I dont mean give Dell a bad reputation but I've had a really difficult time with them.
I purchased an Inspiron 531 and a 8400gs video at the same time form the same sales rep. Little did I know that the 8400gs was not going to work with my 531's power supply. I'm assuming the sales rep made a mistake because he said that the card would work on the system. I emailed dell tech support about the issue and they said that the card would probably or probably not work on my system........whatever the heck that means. I dont want to take any chances. Plus, if im pushing the power supply wouldn't that damage my system? But, anyway,
So, life goes on....
Im looking for a power supply that is at least 350watts with 20amps on the +12volt rail that will fit the Inspiron 531.

Any suggestions?
Thanks in advance

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!
Maybe you can exchange it?

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?

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 picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. 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.

A:No power, no lights but green light on power supply blinks rapidly

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

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.

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

It's been a while since I built a system from scratch and have a... errr... simple question

gfx: Sapphire HD3850 512MB Ultimate (passive)

MB: MSI P35 Neo2 FIR

PSU: Seasonic M12II 500W

The motherboard has a power connector for the graphic card next to the slot.

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?

A:Graphic card power to power supply or connector on motherboard?

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.

As you did not mention any message or display on the screen, I would use this tutorial for a step by step diagnostic.  It also helps to remove the side panel, and visually watch the CPU and rear case fan movement(s).  As you press the power button, pay attention to the fans. Also does the Power Supply LED stay ON? Or did it go OUT when you pressed the power button?

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.

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.

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

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.

was watching dvd and pc cut out completely... high pitch beeping comming from my power supply on hp 110 desktop... when i unplug from tower beeping stops .. plug it back in and it resumes.  No power, no flashing leds ... just constant beeping... no pattern ... just beeps continuously.

A:constant beep from power supply... no power to pc at all.

let me be clear.... beeping not coming from tower.... it comes from the plug in power supply... the square box part of it.

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!

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.

Hello everyone - I have just assembled a new build It will not power up I need a suggestion to figure out if the problem is the case or the motherboard This is a mini-itx build power-up: power New or Build MB? no supply case's The case is New Build no power-up: case's power supply or MB? 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.

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?

I have a Delta DPS-150GB B Power Supply out of an Apple Macintosh Power Mac computer. I would like to use it as a 12v/5A power supply for my model train layout. I have a couple important questions:

1) I need to know the pin-outs of the connectors (1-4pin, 1-14pin, 1-5pin on ribbon wire), specifically which ones control start-up and various voltage outputs.

2) Being a Switching Power Supply, I think there must be a load on at least one of the output rails. Can I create this with a simple resistor of some sort? if so, how exactly what would I need to do.

I can email photo of the connectors if that would halp. I would appreciate any help. Thanks.

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).

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.

A:Self Built PC Power Issue

Could actually be a faulty psu. The symptoms you make-a describe are typical of that.

Borrow, beg, steal or buy (or make-a) new psu and try.

If no possible, take all component out and rebuild from a scratch-a. Even board of mother a too. Turn on with only bare minimum and make-a test. Keep going until you make-a problem. If no make-a problem, have make fun.

Make-a sure board mounted nice in case like maker book say to. Sometimes no plastic washer is good, sometime they make-a good, depending on board.

Important to also make-a check that no single ting overclockified.

Just finished putting together a new pc with a MSI K9VGM-V mainboard, an AMD 64 Athlon X2 processor and a HEC SECC 7K09 Micro ATX Media Center / HTPC Case. When I try to turn it on, it starts up and then less than 2 seconds later it shuts down. Checked all of my connections and everything seems to be hooked up right. Case came with its own 270W power supply. Any ideas? Thanks

A:Newly built PC won't power up

Have your read and followed the guide at the top of the forum for troubleshooting problem builds? If you follow the guide, you will find the cause of your problem.

Next depending on what cpu you installed, a 270W pw supply may be very underpowered. As an example, if you installed a 6400+ X2 with that power supply, that would really be asking for a problem. You might get by with that pw supply with one of the 65W cpus and a very low end video card.

It would really help if you posted the exact system specs; ie mb, cpu, ram, video card, etc, etc, etc.

A:Custom Computer: Won't power up

It sounds like something is shorting to the case. If your motherboard has on-board video, pull out all the PCI cards including the video card and see if the computer boots. You might want to check the motherboard standoffs once again. ATX motherboards usually have 6 standoffs. Make sure you don't have more than 6 installed, only in places on the motherboard, where there are mounting holes

"I got all kew parts and even tested the power supply and power button and everything is in proper." does not tell us anything.
Specifications on the computer you have built would help and what happens when you start your computer do you get anything on the monitor, do the any of the fans start does it switch on then off.
If your graphics card requires power have you remembered to connect it to the PSU.

I highly recommend not using that power supply. Their is no such thing as a $35.00 quality prower supply. A GTX-650 requires a quality power supply along with the rest of your hardware.

I am looking for a Gateway 145 watt U-ATX Form Factor power supply.
Does anyone have any ideas on where I might can get one reasonable.
Also does the form factor mean anything ?

A:Need Power Supply Help

Try this:

or do a google with: micro ATX power supply
Form Factor must be ATX, meaning it is one that switches off when you shut down Windows.
The U stands either for Ultra or (Mu)Micro.
Measure your current PSU to get the right size replacement.

Hi everyone,
Last year i built a computer for a friend and gave him a year's guarantee on parts. He has just brought it back with the same problem as the post below "No Power". He turned off at night next morning no power.
I have changed the power supply.
The thing is, i changed the power supply in June this year, as it went bang.
Could it have anything to do with where he keeps the computer. It is in a cupboard which is on an outside wall (remember this is England) which is pretty cold. No heat gets to the cupboard except the heat from the computer when it is running. The last power supply i changed had what looked like the start of rust on the edges, and i was wondering if condesation is the problem. Or does anyone else have any ideas.
Thanks in advance.

(okay a paste from me)
9800GT which replaced the discountinued 8800GT is what you should look at:

9800GT singe slot:
9800GT Dual slot:

Note: 9800 / 8800 cards generate a lot of heat... You may want to look at a bit cooler running ATI 4850 card... or the slower 4670 card. A dual slot card will help exhaust the heat.

Top level PSUs:
OCZ, FSP, Seasonic, Corsair, PC Power & Cooling, Zalman, SilverStone, Gigabyte

Good PSUs:
Antec, Enermax, Sparkle, Coolermaster. (some of these are TOP end)

Should Avoid:
Aerocool, Apevia, Apex, Athena, Chieftex, coolmax, Dynapower, e-power, Linkworld, Powmax, raidmax. Many of these are exactly the same thing.

I'd say a good quality 750~850watt PSU should handle that.

You could have a problem with the mobo-battery. This is cheap to replace.
Before you do that, make a note of any settings you have changed yourself in the BIOS.
Careful you don't brake any bits when removing/installing the battery.
Your PSU should be OK. Run the PC without OCing the graphics card (that may also be a problem!) for a while.

well first of all check if your aiw 9700 pro has a molex power connector,i think the 9700 pros do have that,if they do than this has to be connected separately to a free power cable from your psu.200 w is not optimal even if you werent putting in a 9700 pro,you were bound to run into problems if this was a generic psu.since you have a amd 2800+,a 120 g hdd,512 mb ram and also some optical drive(i am guessing)a 200w would not be sufficient for your setup.get a new psu from a respected psu manufacturer like antec or enermax forton.a good psu is a one time thing-put it in and forget it.if your 200 w is a generic brand you really ought to consider an upgrade to atleat a 300w+ psu higher the better(if you ever want to upgrade or put more peripheral in).

Where do you live?

If your real mains voltage is 115V then you should get your PSU fixed/replaced. I wouldn't risk running it at 220 very long.

If your mains voltage is 220V then 220 setting is the way it is supposed to work. If it wokred at 115 then you were very lucky not to burn down you PSU or motherboard.

A:H30-50 Power Supply?

hi DKL2,
Welcome to the Forums.
Looking at the parts, the H30-50 (90B80012US) uses a Thin Form Factor (TFX) PSU and can use one of the following:
FRU#: 36200450 - FSP240-40SBV 240W IPG ES SINGLE PSU (full specs here)FRU#: 36200451 - ACBEL PCB020-EL1G 240W IPG ES SINGLE PSU FRU#: 36200452 - LITEON PS-4241-01VB 240W IPG ES SG PSU
The EVGA GT 740 Superclocked 4 GB has a max TDP of 64W so this should work (combined with the i5-4460 CPU which has a TDP of 84W). Note that the GPU requires a  6-pin PCI-E power connector and it might be tight fit when you insert it inside.
  - Sample image (inside the H30-50)
As for the RAM, this unit uses 1x8GB stick (there are 2 U-DIMM slots, max 16GB).
