What was your power supply wattage that you replaced? Did you test to see if the Diablotech is functional, i.e. test it with a multimeter?

Recently the fan on my Help Power Replacement Supply W Cooler Master Power supply started to make increasingly loud noises Upon investigation I found that the fan was locking up and then fighting to spin I tried dusting down the system but had no luck in getting the fan to function properly So yesterday I went out and purchased a new W Antec Power Supply Power Supply Replacement Help to replace it I powered down my system shut off the power supply and removed the power cable Power Supply Replacement Help With an ESD strap tethered I documented the connections removed the cables and replaced the Cooler Master with the new Antec PSU I then Power Supply Replacement Help powered the box back up heard it post figured it was fine and put my monitor back on it This is where my problems begins My system configuration is as follows motherboard nforce sli vid card GTS RAM GB DDR HD two GB raptors in a RAID for my OS HD two GB k drives in a RAID for storage PSU W Antec OS Windows XP When I power the box up all fans are active the hard drives spin up the mother board posts normally and displays the quot FF quot status on the motherboards LED indicator signaling a normal boot process The BIOS runs and I see it detect my two RAID stripes and it indicates that they are healthy It gets to the boot from CD check and goes to a blank screen It does not progress any further I am not of the opinion that the old PSU somehow damaged some system components as the actual power output was fine and my system functioned as expected it was just the fan making nosies that spurred this replacement I thought maybe removing the power caused the motherboard to lose its settings and changed the boot order to boot from my second stripe which is just for storage Logging into the BIOS I confirmed this was not the case At this point I am kind of at a loss any suggestions would be greatly appreciated nbsp

A:Power Supply Replacement Help

The only thing I can think of is you maybe unseated something a bit when reconnecting stuff. With the power off of course go through and reseat all the power connections, data cables, and add-on cards.

Any reason you didn't just replace the fan in the PSU rather than the entire PSU? Maybe put the old one back in temporarly just to see if it works still.

I have a ThinkCentre M81 which has been regularly shutting down without warning and then re-booting.A technician saw that the power supply does not appear to be the correct type and suggested that I replace it.The M81 manual indicates that the model is equipped with a 280w power supply.  The Lenovo website lists a 240w power supply as the replacement model for the M81.Will using the 240w power supply cause the same problems?Why doesn't Lenovo offer the 280w power supply that it indicates comes with the machine originally.Thanks.

Hello, I have replaced the power supply on a Gateway PC. The PC starts to boot then hangs with the message "no response from MSD". I think I may not have re-connected all the devices properly, or, not plugged in the power to somewhere. Rather than start troubleshooting I thought someone here might know that specific error code so I can go directly to the problem. Any help? Thanks.

A:Gateway Power Supply replacement

Sounds like there is no signal from the video card. How far along in the POST does it get? I am also not sure if Gateway uses standard ATX power supplys, you may need to get one directly from Gateway. Compare the pinouts from the old PSU and the one you just put in and see if the voltages are all the same with the same number of pins. This would be the connector that clips onto the motherboard.

I replaced a bad power supply on my custom built desktop running Vista Business. Everything is up and running except for the audio. I deleted the hardware in device manager and let Vista detect it and install the driver, but that did not help. I did go through all the basic troubleshooting tips without any luck. The sound is onboard and it is enabled in BIOS.

Anyone got any ideas?

For and HP Computer. The power supply model is a Hipro HP-2537F3R and is 250W. I thought that just any ATX power supply would work but i talked to a local vendor and he told me that I have to find one that is specifically made for HP or Compaq Computers because of some kind of difference in Wiring. Is This true? He can get me one at a decent price, but its gonna take him about a week and i was hoping to get one sooner. So i wanted to see if there was anything compatable that i can get locally. Thanks.

A:Trying to find a replacement power supply.....

HP uses a small form factor psu as in all the ones I have replaced. They are ATX psu's but to get them to fit your case you may want to wait on the other guy as in if it does not work you can return it on their business for getting you the wrong part and not be stuck with something you can't use.

I usually leave my machines on permanently as they are set to download and install updates overnight, only switching off the monitors. Went on holiday and turned everything off but on my return the XPS would not respond to the power button - green light on the PS is on, but dim, amber light on the motherboard is on. Reseated the power cables, no change. Jumpered the green cable on the 24pin connector to a black one - PS fan starts up, but still no boot up. I suspect the PS is faulty but I am having difficulty locating an exact replacement - proprietary ones do not seem to have all the necessary cables.

On restart (this time with mouse and keyboard) it reached the first XP screen with the progress bar but then it rebooted itself before reaching the user login screen. Only safe mode now works.

Yes they're not so good at fiability - all their cheap or main-stream products (laptop, printer) I bought from them dissapointed me faster then the competitor's, in the same amount of time. They sell a laptop 20-50 dollars less than others (similar specs), but on the long run you loose, because the product fails faster.Never bought expensive HP stuff, so I can't say anything about those.

You would have to ask them for a list of that which they did.

What brand, model, model # PC, or same information for the motherboard?

Computer specs would be helpful.

Which ;power supply was it: brand, model, model #, wattage? Same for now?

If you aren't happy, take it back & have them install a new power supply and politely insist that they demonstrate it to you before you accept it back.

Start the computer, note time from start to desktop appearance or log in screen appearance.

Start the computer in safe mode & do the same.

To start in safe mode, start > run
type: msconfig
boot.ini tab
put a check in "safe book"
exit without restarting
Shut down.
Turn on.

Ive just fixed a friends PC as it was starting up and then 1 second later stops (only CPU fan spin) so i tried resetting the CMOS which i doubted would work but it didn't take long and of course didn't work. So its the power supply. Then i sent away for a new PSU for them id used a number of times before (the brand not the actually power supply) and installed it and booted the first time fine but as i though it had lost the date and time. Now i didn't think much of it so i unplugged it and took it round and it did it again. So how can i stop it?. It just looses the date and time but they are no way computer literate and would implode if i mentioned using the BIOS so any thoughts?.

Hi there,

I've been having some power issues with my laptop for a while. For some time now, my laptop has been constantly losing power and shutting off, regardless of whether I am running off the battery or the power supply. There does seem to be inconsistency as to whether the computer is getting power from the supply (it will be plugged in and off, and sometimes the light that indicates that it's charging will be on, and other times it won't.) I've also noticed that the power supply, as well as the bottom of the computer, get extremely hot. Sound like a bad power supply, or something else? I just think it's weird that it dies regardless of whether it is running off of the battery or the power supply. Perhaps the battery isn't getting power and it thinks it is?

Thanks for your help!

A:Laptop will not start. Bad power supply?

You don't tell us which laptop you have, but the odds are that the power cable connection into the laptop has failed because the socket is coming off either the power controller or the motherboard. An unstable connection can arc and cause heat. You need to get this fixed before it does any more damage and becomes unrepairable. A decent laptop repair should do this for less than $200/£100 or local equivalent.

Good day everyone maybe someone can give me some light on this issue I have identified this as being a power supply problem however it may be related to another component within the mother board This is what happens Since a couple of weeks back I ve noticed that my machine sometimes just won t boot up The specifics of the PC hardware I assume are unimportant at the moment but just for the sake supply Bestec Power 250-12Z start ATX won't of explanation let me tell you that we are talking about a tower PC de-branded HP P which as you all know that means it has no support from its OEM Anyhow the problem is that sometimes it just did not start up by pushing the power on button Some of you may think it could be due to a problem with a loose cable or the sort believe that is not the case Well this has been Bestec ATX 250-12Z Power supply won't start going on and off but since yesterday my PC has been even more stubborn to power on Today after even removing all external cables and trying a few things it did not power up no fan no sign of life but just a green light I assume it s an LED just below its power connector that while the problem existed it was blinking green I even removed any cable from the HDD DVD and any other power connector and still the same behaviour Ok after trying this and that I could finally make it boot up by the way I m writing this from the same machine in mention but I m affraid this may happen again and probably it s a sign of something worse to come or just break completely Another thing I noted is that when the light is solid green I can power up which gives me the impression the power supply was in a sort of locked state I ve been looking for any manual or troubleshooting guide from the manufacturer Bestec in order to better identify the issue but have been unlucky so far I wouldn t like to replace it without having more info regarding what is causing it Any ideas or anyway I can find this power supply troubleshooting manual Thank you so much for any reply towards solving my issue regards Moris nbsp

A:pc won't start - power supply failure?

Okay, this could be two things: the power-supply or the monitor, both of which you'll need to find another of, at least for testing purposes. If you get the power-supply then make sure it's the same type and make (look on your computer and give us the MODEL number for your specific computer, this'll give us the specs we need to determine what kind of power-supply you need). I don't think it has anything to do with your game, but it could very well have something to do with your graphics and/or your video card as well. Is it the power, or the dv15 pluggin (that's the plug where you hook it to the comp itself, NOT power, the other one) that messes it up?

Most likely this is a power-supply matter as you pointed out and that'll require a replacement. Those things cost alot, so if you can find a used computer at the dump or something or go to a local hospital and buy one for cheap, or have a friend with one they don't use cuz it's broke or something i'd do that, but make sure it's compatible!

So I just recently purchased a new desktop as my laptop fried. I bought this desktop with getting a new video card and power supply in mind. I purchased an ATI Radeon HD5750 which requires one of those 6 pin power cords. The new power supply had what I need.

When i switched out the old 250W for my new 500W, I received no results. The computer would turn on, all fans would run but I would get nothing on my monitor. The motherboard green light would also turn on. When i swapped back to the old power supply, everything still works great. Any troubleshooting tips? Im told that this might not be a great power supply either. Thanks in advance.

This is a problem I had since a few months, but back then it wasn't that irritating. Sometimes when I tried to start my computer it would start up mechanically, so to say; all the fans were working and so were the HDDs, but not the BIOS. Nothing would happen, and the monitor was ever idle. A simple cold reboot usually solved the problem.

Now, like I mentioned, the problem got serious. The computer won't start at all, i.e. nor the fans, nor the monitor, nor the HDDs will ever start up. It just keeps restarting itself every second without any enhancement. I also found a solution for this problem by setting the power supply to 0, and then back to 1 after a few hours(!). Restarting after just a few minutes doesn't work. What's the matter? Have you ever encountered such a problem?

Hi. Recently got a brand new PC on an auction website and have had nothing but trouble from it. Today it's PSU started making a continuous extremely loud whining noise like a jet-liner taxiing on the airport, and the whole system was going crazy; the OS kept crashing etc, and before long it crashed again and could not be restarted. This prompted some Web research on the PSU (an ISO-500PP 420 Watts) and was not surprised to see that they have got an appalling reputation with fake "technical specifications" on the label.

Hi everyone- This is my first time here and I need help I m a newbie and not real technically advanced but here s my problem A few days ago I was trying to connect my scanner to a USB port and I noticed my mouse got stuck I hit the power button on the front of the computer to turn off I rebooted and then I couldn t enter my windows password because my keyboard didn t work either I then turned off the computer from the reset button in the back Then I flipped it back and tried to power on my computer and it has never turned on again I should mention that Power Supply? doesn't or Motherboard start Computer when I try to turn on the computer there are no sounds no fans moving It s just silent and dead It doesn t try to do anything Could it be the power supply or motherboard I tried using different outlets and changed out the computer cord that runs to the outlet My friend helped me build my computer about years ago I have left it Computer doesn't start Motherboard or Power Supply? running mostly which I guess isn t good Could I have worn out my computer faster I don t even remember Computer doesn't start Motherboard or Power Supply? what kind of mobo I have or really anything I have to look and my friend ordered the parts yrs ago The only repair I ve ever had to do on it was replace the fan about months ago My friend instructed me to open up the computer and see if the wiring from the power button to the motherboard looked ok and it looked fine I just wonder if the keyboard mouse problem first gives any hint to what could ve happened There were no weird sounds no smells nothing burned that I could tell My friend and I are going to look at it this weekend but we could use some advice I am going through computer withdrawal at home am posting from work right now Oh regarding the scanner I guess I should mention that my USB port I was trying is in the front of the computer below the power button However I noticed I can t fit it in the USB port anymore because it s bent or something Maybe this did something to affect the power button itself So I never succeeded in getting the scanner in there because it didn t fit in the quot bent quot USB port then the mouse froze etc Then I was checking my cords in the back to the mouse and keyboard and then the whole non-powering thing happened I also tried a suggestion where I unplugged the power button from the Mobo and put a dime on top of the two pins to try to power it on and nothing happened Help I m desperate nbsp

A:Computer doesn't start Motherboard or Power Supply?

It sounds like there was a short in the USB port and it damaged the motherboard. There is electrical current running through the USB port.

Probably need new power supply as on/off switch on back of computer does nothing (won't turn computer on or off by that switch).

However, the ritual I seem forced to follow makes me wonder if that is my only problem--- Let me explain:

Hitting the switch on the front of the computer doesn't usually result in starting the computer-- but what does start it is to unplug the chord from the back of the computer and then plug it back in (unpluggin/pluggin in at surge protector doesn't usually have same results).

I leave machine running 24/7 and it works fine--- however, I am concerned that I want it repaired before it fails altogether.

Your help would be appreciated

A:Switch on Power Supply bad-- and need to plug cord in to start

Having to remove the cord to start is usually indicative of a PSU fault.
Though unplugging or turning off should have the same effect.

PS a "chord" is a series of three or more musical notes...

I have a pc that s been sitting for jumper, supply wont power PC pwr fine with start about years now worked great before Went to plug it back in and it won t start I assumed the power supply was at fault at first The green standby light is lit on the motherboard but just to test I jumped the green and black cables on the pin connector and everything worked great Reset the CMOS still no luck Then I went to check the power switch by jumping the two PWR SW prongs with a screwdriver Now PC wont start with pwr jumper, power supply fine here s the weird part it started up fine the first times Went to connect the monitor and start it back up with the screwdriver nothing I used a different tool to jump the switch and strangely it worked just fine again Now its back to not working tried several different metal tools and nothing I have no idea why the switch is only working intermittently I just tested everything again by jumping the pin connector and that still works just fine nbsp

Even more weird, I've found if I jump the green and black wires on the 24 pin, pc starts, remove the jump, pc shuts down, then I'm able to jump the PWR switch and the pc starts as its supposed to. I've tested this 3 times and it never fails
Why would the switch only work after jumping then removing the jump on the 24 pin???

This is an attempt at understanding what makes a power supply wake up.

I believe that you have to short a couple pins in order to make this happen.
Anyone know what pins to short?
Or am I on the wrong track?

A:Computer won't start anymore after closing it with Power Supply Switch

Hello and welcome to Techspot.

If after trying your other psu it`s still dead, It`s got to be either the mobo or cpu.

I think for whatever reason, you`ve had a short circuit of some kind and it`s fried either the psu/mobo/cpu.

You`ve seem to have tried all the right things, so I can`t really suggest anything else.

Regards Howard :wave: :wave:

A:Computer shut down - power supply problems? - fans start/shot off - not booting

Depends entirely on what the issue is. If the PSU is supplying power but not stably and the board isn't powering up because of that, you could be looking at just a PSU replacement, or various components.

What type of processor do you have? If it is an older model Athlon and the fan was not spinning fast enough, in theory it could have overheated and fried, though that is a rare occurence unless the fan outright stops spinning.

So I turn my computer off one day only to find it wont start the next day. I open the case up and see the led is on. I flip the switch on the power supply off then on and quickly press the power button. My computer starts but the following time I shut down the computer it again wont start and now the led is blinking. I've never had any issues like this before, any help would be appreciated.

I don't routinely use many usb devices, only my mouse and keyboard and every now and then my ipod. I figure the issue is likely either the power supply or the motherboard. The ps is almost two years old while the motherboard is only about three months old.

A:Computer wont start, power supply wont start, blinking led

It sounds to me like your PSU is the problem, get a hold of another and plug it to your computer and see if that will make it start, if it doesn't it might be BOTH your motherboard and PSU. A bad PSU will burn a motherboard.

Toshiba Satellite L305-5955, Ive taken apart and replaced power jack. Not directly soldered to motherboard. While still apart, and battery out/in, connected power supply and still absolutely no response. Power supply is NOT original, and slightly different specs, i.e original 19v..6.3A

current 19v..3.1A

A:Toshiba Satellite L305-5955 does not respond to power supply, new power jack

Almost certainly the problem is that the current rating is wrong, if the laptop needs
6.3 A of current, it won't function on less (just as you can't use a 3A fuse for a kettle!)
Unfortunately it must be the right current rating, I know, I've been caught that way too!

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

I have a Dell 8600 about two years old. When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so. I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally. Any ideas?

The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

Is there any reason I should connect the power for the card to the power connector on the board instead of directly to the power supply?

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

Hello guys.  Can anyone help me understand the power supply on the HP Envy Phoenix 860-019?  The PCIE connector 6 pin connected to the GTX 960 has black and white wires.  Shouldn't there be yellow and black wires?  Yellow is usually 12 volt and black wires ground.  Is the 6 pin connected to my GTX 960  supplying a standard 75 watts of power or something else?  I want to install a GTX 1070 but the 6 pin wire colors are not the industry standard color scheme.  Also there is a 2 pin power connector with a white and black wire.  Usually a 6 pin and a 2 pin can be used together to connect into a 8 pin socket on a GTX 1070.  Will my connectors supply the needed power and connect properly because the color scheme on the wires make no sense. Thank you

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place. My warranty with best buy has expired, so I need to figure out how to solve this problem on my own. I can't just leave it like this because the cord comes out really easily and I can't continue to work with such a tenuous setup. Anyway, is this just a matter of replacing the entire unit inside my laptop? I know you probably need more information, but I'm not sure what to provide, so please ask any questions. The laptop is a Toshia M-45, about 3-4 years old. Thanks in advance

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

Hey, got quite a problem with my laptop.. It's a Medion Erazer X7813, worked well for ~2 years.
I was doing a graphics card benchmark yesterday and it stopped in the middle of it(monitored temperature, it was at ~80 degrees Celsius when it turned off). No bluescreen or anything just off and I couldnt restart after that(no fans nothing). I thought it might be the power supply, so I tested it, but it was doing 19v when not plugged in, but when I plugged it in and unplugged it again it was at 1v. When testing I unintentionally shorted the power supply and it showed 1v after that just as it did after plugging it in, is it shorting inside the laptop? Could it be the battery or something more serious like the MB? Any ideas are welcome!

Linkworld LC - B This case comes with a volt watt external laptop-style power supply that plugs into the rear of the case just like New Build no power-up: case's power supply or MB? a laptop power supply plugs into a laptop - a barrel connector Inside this power connection connects to a power supply component that is not like a regular ATX power supply but is on a printed-circuit board New Build no power-up: case's power supply or MB? mounted on the case This has several capacitors and other stuff From that comes the -pin and -pin power supply lines for the motherboard I assume the -volt power supply for this external power supply unit is right since it came with the case It was watt The processor is an IBM t with TDP of watts Lower-powered CPUs can be put in a small so I assumed the power supply might be under-powered I ordered a -watt volt power supply with the right size barrel - and same polarity pos inside The MB is an ASRock H MV-ITX It is mini-itx form factor Still same problem Everything is connected correctly When I press the power-on button an external CD drive I have plugged-in spins up for a while But no power light comes on in the front of the case there are no POST beeps the fan for the CPU does not spin up No other signs of life So power is getting into the MB - the external CD drive is plugged into a USB socket in the rear panel of the MB After trying a watt and watt power supply I believe the problem cannot be the power supply cord Can it be that I have too little load I don t think so I plugged in another mm fan and an ol-fashion floppy drive just the power connection to add more load - same thing no power-up no POST nothing but the CD drive will spin up when I open-then-close it yet again So here is the help I need what else can I try -assuming the MB and case are fine is it more likely the case power supply is bad or the MB --Thanks nbsp

A:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

Hi I m currently a computing student so I rely won't up power (poss. Computer supply) power on my computer a lot for my studies and was hoping I could get some quick advice troubleshooting on here So here goes I ve had a problem with my computer recently it s been working fine Computer won't power up (poss. power supply) for a year or so with no problems and then one day i tried switching it on and nothing happened I tried once more and then the power short circuited I then had to turn the power back on from the mains switch The strange thing is my housemate had exactly the same problem and after searching for the answer he was told it was due to a static buildup and the solution was to take out components graphics card RAM e t c and put them back in I tried this and no luck I was thinking due to the short circuit there may be a problem with a fuse in the power supply other then that I m completely stumped and would appreciate any help given Many Thanks for all help received nbsp

A:Computer won't power up (poss. power supply)

Does it happen with any other appliances? as in does using the toaster while using the kettle While your mate is in the Electric shower, telly on, or ironing?

Possibly a static build up, it is possible, Wher are you situated??
What voltage are you on?

What is the make and model of your comp? is it the same as your friends?

is your machine custom built or is it a brand?
Answer a few of them and we will try to narrow it down 4 you..

Mean while if you could get your hands on a spare PSU that would be handy. And remember when dealing with PSU's alway leave them to sischarge for at least 24hrs,
the 3 D'S, Disconect, discharge, dismantle.

Finally broke down and started building a new system - I m too old to game this all started out as a home video project Anyway - gathered all my components now I m working to assemble them The case power plug. fan power New for supply, no schematic, looking came with New power supply, no schematic, looking for power fan plug. an Okia Model -ATX power supply But no wiring schematic I m trying to identify the power supply fan plug - what New power supply, no schematic, looking for power fan plug. seems to be it doesn t at all match the connector on the board And I ve got that positively identified by the board manual The board has a small male pin connection The only thing I can find that might be the fan connector coming from the supply is a small pin plug at the end of of the New power supply, no schematic, looking for power fan plug. strings of drive power harnesses Nothing tucked up behind the supply case or anything Is that likely to be it Or would that be for a floppy or something I tried to Google for a wiring schematic but could find nothing In fact nothing much at all on this brand of supply - just a couple places that sell them Please don t tell me I got an el cheapo that isn t worth having At the risk of getting ahead of myself in case I need to adapt something like that to the different style male connector on the board in this case or something else I may find as i progress is there some type of source for adapters or what would I do Bear with me this probly won t be the last question I ll dream up - just getting started While I m at it - the board manual talks about a connector for a power supply that senses board temps - that s another reason I d like to find a schematic or some sort of instructions for the power supply OH The connectors for the fans in the case don t match the connector on the board either The board has another small male pin connector for the case fan s but these have a larger bigger pin pin connector Again - I suppose it s adapter time Guess I ll need that source Thanks for helping an quot old quot computer student still and probly always in a definite learning curve nbsp

A:New power supply, no schematic, looking for power fan plug.

There are basically two voltages available to you: 5V and 12V. Doesn't really matter where you get it from - some pin on the mobo or some wire from the PSU.

From the PSU the yellow wires are 12V and red ones 5V, black is ground. The fan voltages should be written on the fan itself, the black fan wire is ground, red may be 12V or 5V depending on the fan voltage.

Fan headers on the motherboard should be labelled so, check with a voltmeter what pin gives out what.

Ok so lately I have been getting a BSOD at very random times and it looks like a Diver Power State failure. SO all of my friends and every website I go to makes it seem like I need to get a PSU. Right now I have a Quad Core and a 8800GT and 375W PSU. So my friend told me to get a new 700W PSU.

So, if the only fix is to get a new PSU? I tried to rollback my GPU driver but it didn't help.

So any ideas?

A:Driver Power Failure = New Power Supply?

You're greatly risking the health of your whole computer while running with such underpowered power supply. Do yourself a favour and get a quality PSU. That's the cheapest one that is enough and of good quality that I could find with a quickish search.

I have a generic MB (P-120 CPU ) which I just switched to a different case and power supply. It has an extra "six pin power type connection" in the middle of the board. Only one supply that I have matchs this and the wires are three green and three black. What is the funtion of this connector, it looks from the wire colors to be some form of switch.

Its a case of not wanting to swap out the power suppy from my other unit unless necessary. I have 4 other supplies and none have the extra wire, which is listed as P10.

Many thanks in advance.

A:extra power leads on power supply?

Sounds like typical extra +5V lead and can be used for any number of things...(riser cards,backplanes,to drive extra slots, etc.)
Without knowing the specs. on your motherboard this question is impossible to answer...Post Mobo identification (make/model) or obtain FCC ID and post that. Perhaps we can find a more definitive answer for you...BOL

While installing the new optical drive, you might have inadvertently loosened one or more connectors. Recheck all data and power cables to make sure they are tight, including all those to the motherboard.

A:Power Supply Question & HD Power Consumption

Power Supply Question & HD Power Consumption, Pt. 2 - Laptop vs. 3.5"

My second question is this - I have a BTV server that needs to be on at all times during the season to record shows during day and evening.

Suffice it to say that you CANNOT reliably put one of the critters into sleep/hibernate mode and expect it to wake up and reliably record a show. It just won't happen.

Now, this is one case where I can use "Green" 3.5" drives, but I am also considering banking 500GB 7200RPM or even 5400RPM laptop drives. These will all be on a raid controller, but since they will be in pass-thru mode or RAID 0 mode the controller won't freak over TLER like it would with RAID 5/6 and mark the drives bad. The controller also has more than adequate cache to handle a 5400RPM spindle as OTA HDTV generates little more than 2.5MB per second per channel. Even 4 channels at once is 10MB/s and that should not tap the ability of a 3Ware controller with cache on 5400 RPM RAID 0 or even pass-thru drives.

My question is this - 2 500GB laptop drives burn much less startup and idle current than a single 1TB 3.5" drive. Has anyone tried running multiple laptop drives on a RAID controller, and what sort of luck have you had? What sort of sustained throuput can you obtain?

Electricity is a huge factor here, at 12 cents per KWh. I can recover the marginal cost of 2 500GB laptop drives vs. 1 1TB 3.5 drive.

Case construction and drive cages are not the issue here.

I reckon a 500W wouldn't be enough but a 750W may be the right one. I had a look in a few forums and they had 650W & 750W etc but not 500W.

My PC suddenly shut off and wouldn't turn on, but the mouse and motherboard lights were still on. A tech took my PC and ran some tests. I assumed that either my Power supply or my Motherboard was unfunctional but he called me back telling me that it was neither, and that the problem was coming from "a part" that gave power to the motherboard. The replacement of this part would cost $80.

Am I getting ripped off? What part could possibly cost $80 and isn't the Power supply?

A:Power supply and mobo are 100%, no power

There are some motherboards that have a power on button directly on the motherboard. I don't suppose you have one of those? There are some BIOS' that can enable the keyboard to power on the PC by pressing any key. I'm using one of them now. Of course, the problem with that is to get the PC started in the first place so you can change the BIOS setting (if it has that setting).

What motherboard do you have?

A:Power Supply - "The AC power adapter type cannot be determined....."

You are correct, the failure is due toloss of the power supply ID signal. Sometimes this happens because of strain on the plug, which breaks the signal wire. Some even are so severe that the insulation breaks away from the plug; this is due to rough handling. The other cause is one or more of the power socket solder connections to the system board become broken. This also is related to severe handling. I have seen one case where all three power connections and three of four mechanical connections were disconnected. If the power supply is bad, a replacement will cure the problem. If not, then the socket is bad, and this will require a system board replacement. If you are experienced, you can try to resolder the connections. I am experienced and was not able to get my daughter's E6000 to work by resoldered. More recent Dells are using a replacable power connection board which is a much cheaper repair.

I replaced the power supply and now when I push the power button to turn the computer on,  all of the fans will turn on for about a half of a second as the switch makes contact, but then turn off and the computer doesn't boot. I suspect the power button is bad as well. It's like it starts to make contact when I push it, and then nothing.  Any suggestions on what may be the problem? If it is the power button/switch, can this be replaced, and if so, where can I get a replacement?
