Power supply (PSU) keeps blowing when switching on

Q: Power supply (PSU) keeps blowing when switching on

My PC has been working fine for a couple of years then all of a sudden yesterday the PSU failed. The fuse at the wall had blown so I replaced it and then plugged the 3pin kettle lead back into my PSU. Turned on the PSU and "Bang" a spark flew out the back of the PSU and so did a waft of smoke. Now its dead. I bought a new PSU and rewired the internals of the PC and double checked all wiring. Plugged it in switched on the PSU. Turned on the power button of the PC and "bang". The PSU emited a pop and smoke and again its dead. Could this be a motherboard problem. ? Please help. I'm about to order an new PSU but I fear it is doomed unless I change my strategy !

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

A: Power supply (PSU) keeps blowing when switching on

When a PSU fails, especially in the manner in which you describe not only does the psus die but it can damage the motherboard, harddrives, etc. I would not buy a new PSU at this point until you can determine if the mobo is good.

Hello there,

This is the first time I have posted.
My PC power supply keeps blowing the fuse. it tends only to be when I am doing something that uses alot of memory, especially when trying to convert .avi files into .mpgs
The PS is 450w and I have an athlon 2400 processor and 192MB RAM
Do you think the power supply is inadequate as I have upgraded it recently and it doesn't blow the fuse as often now but it still does it when using alot of memory. I have tried it in different sockets and have the same probs.

Any help would be greatly appreciated. Mitchy

I m on a Sapphire Radeon X Pro MB PCI-Express video card A few weeks ago my card was running much better than now like an X should but then the power supply blew and i got a replacement from the manufacturer of the same power supply a very cheap w power supply that came with my case-Logysis Phantom Black and now my video card performs HORRIBLY even in COUNTERSTRIKE my frames are horrible they drop down to when i see an enemy and i cant even speak of playing need for speed underground or half life they frame very badly this really started happening after instaling the new power supply is it possible that the power supply blowing damaged the video card or worse the mobo i feel like killing myself but the comp is running fine just cannot perform in games P Prescott Ghz not causing blowing Power supply underperform?? to card video OC d EPoX EP- EPA Sapphire Radeon X Pro PCI-Ex GB RAM Thanks in advance nbsp

A:Power supply blowing causing video card to underperform??

First get a good quality psu from Enermax/Antec etc about 400w to 450w should be fine.

The name of the game here is quality not quantity as your videocard will be power hungry.

Secondly it is possible that your videocard has suffered damage due to your old psu blowing.

And last but by no means least I would recommend that you get antisurge protection if you haven`t already.

Something like this is what I mean

help, I have several questions, but don't know where to post them, I need a power supply- the one i have is out , it says pc100-switching power, model PS150- where can i get one? ac input 100v-240v auto 3a 60/50HZ
My other question is about parts for a mother board it takes an AMD K6-2 socket 7 processor if that helps, but it has no connector for the mouse, all it has is 5 pins that the port connects to, i also need several of these, anyone who can help, please do so, I am sure what i need are ps/2 connectors, but the only ones i have seen don't solder in, thats what i was looking for, so it won't be able to jar loose.

About a week or so ago, i thought it was time to switch out the power supply to a new one on my desktop xps 410, soo i can replace my graphics card too,(yes i know it is kind of ancient, but it all i have for now. and what i am working with) so i switched to:

HIS iCooler H777F1G2M Radeon HD 7770 GHz Edition 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card

and a

COOLER MASTER eXtreme Power RS600-PCARE3-US 600W ATX12V V2.3 SLI Ready CrossFire Ready Power Supply

my mobo is: a lga775 with a core 2 running at 1.86 Ghz AKA the one that was originally with the desktop.

Hopefully this helps. Thank in advance for all your help.

A:blowing out power supplies

Well, you have two possibilities. Either you have a problem with the mobo, or a problem in the power outlet, surge strip, or the line itself. Since you seem to have at least a few dead PSUs, you might take one to a technician and have him look at it and tell you what is blown, this could help you figure out whether it was blown by the line coming into the primary, or if it was an overload caused by a fault in the mobo.
Just from the description alone, I'd say it was power spikes or an intermittent dead short on the motherboard. Look to make sure nothing is in the case that could be periodically making contact on the mobo that might cause a short, also look to make sure nothing is wedged between the case and mobo.

Does anyone have a solution to why my motherboard is blowing power supplies? I read one post that had an answer that motherboards don't usually blow power supplies. WELL mine has blown TWO. I have a power supply tester and the second one I know was good just before plugging into the motherboard, now it energizes for about 2 seconds. If I turn the power supply off using the I/O switch on it I can get it to energize again. I have lighted fans, they light for about two seconds then go out, everything DEAD. I can repeat this process as many times as I wish with the same result. This problem just all of a sudden started. ANY HELP?

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 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

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.

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

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.

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.

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

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?

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.

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.

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.

My power supply died a few days ago and I have replaced it. My PC will now boot but will not send a signal (turn on) the monitor. Everything on the PC seems to work but it just will not turn on signal to the monitor. I have tried two different monitors with the same result.

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.

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!

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.

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

ok, I am confused here. when I power on my laptop, with it plugged in, it shows the battery status. once the battery runs low, it does as usual, "switch to AC, or loos you progress" (something to that effect). even though it IS plugged in, it does not recognize it as that.
once the laptop is OFF, i can plu it in and it will it should. but once powered on agsain, it automatically goes to battery.
i have upgraded to XP SP3, and i am totally LOST!!

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.

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.

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?

 My HPStream11 started switching itself off. The power button was blinking and now it doesn't work. It started up again a few times, enough for me to reset the whole system, but then died again shortly afterwards. The battery light flashes on and off when I plug the charger in. I have tried the usual suggestions like holding down the power button, pressing escape, F11, and nothing works. I have only had the laptop a few months. I will not be buying HP again if this is what happens to them.

I have a Compaq Presario R3000 that I've owned for about 1.5 yrs. Several months ago, I noticed that it keeps switching to battery power even when plugged in. It used to happen when there was movement but now it can happen at just about any time. I assume it's a problem in the AC jack but what I want to know much trouble is this to "fix"? Is it a fairly common problem with laptops?

A:Laptop keeps switching to battery power

It's a very common issue with laptops, and I'd get it corrected BEFORE you end up with this! This is the second of two laptops I've seen in the last year that people ignored the advice to deal with the loose power connection.

As to how difficult it is to fix, that's going to depend on the specific make/model of laptop, and how much disassembly is required to repair/replace the jack.

P.S. Yes, the MB was destroyed and needed to be replaced in both laptops.

Not sure what exactly is going on here, bought an X1 Carbon 3448-2D9 second hand yesterday. Battery level is showing full and it appears to be charging properly but removing the charger the laptop switches off instantly.The laptop does turn on without the charger attached and will run for a while until it switches off by itself again, all the while the battery level is showing over 90%. Powercfg report shows that the battery is in reasonable condition.I could return the laptop but I quite like it and would rather fix it if I can, just need a little help diagnosing the issue. Any pointers on further tests or fixes would be greatly appreciated

"The adapter Power connect a Dell W AC adapter or higher for best system operation quot I press the F Key and everything works fine I ve read about this on other websites and most say it s a design Power Supply - "The AC power adapter type cannot be determined....." flaw in the power supply after the cord has been properly wound around the supply as designed Apparently a few of the cords internal wire strands Power Supply - "The AC power adapter type cannot be determined....." become broken and cause this message My computer is from June and shouldn t be having this issue so early or ever This seems like a flaw that should have created some type of manufacturers recall since so many people are having this issue I m of course out of warranty will Dell replace this free of charge nbsp

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.

Hey Guys,

I recently bought a new Case for my PC, just to provide more space and air inside to make it cooler, plus it looks cool

But anyway, my problem is possibly the power supply. If say im playing a game, Mainly World of Warcraft, My computer will just Die, as if power has been literally cut. The Wiring between the PC and the mains is fine, i tried replacing the power cable and it still does it. I can only access my computer if i unplug the pc from the back and plug it back in a few minutes later. I do have a 350 W psu which never did this problem which i could test, but does anyone know how I could perhaps avoid doing so?

A comp tech recently replaced my 200W power supply in my HP Pavilion tower. I asked him what he replaced it with and he said "A better one." I don't know what the wattage is on the new unit, but since then, I notice that the screen desktop is slower responding (opening programs from desktop icons) and also Windows Explorer (not Internet Explorer) is also slow to copy, move, delete or open folders and files. However, once I get a program to open, it runs normally. I've tried all the usual tweaks, even a system restore. I also tried to reset the setting priority for explorer.exe to "high" through Task Manager, but it always resets itself back to "normal". Nothing seems to improve the slow performance. I wanted to know if replacing the power supply could have anything to do with slowing the desktop and explorer responses?

I am currently having issues getting the pci slots to work.I beleive it is because the new video card I just installed(ATI 4870 512mb) requires two 6 pin connectors.Where as my old card only required one???

are HP power supplies proprietary or can i plug in any ATX power supply without frying the Motherboard? because i know that some of the older dells have power supplies that have the same connectors as ATX power supplies but the wires are arranged differently which causes the motherboard to fry when connected and powered on. i want to upgrade my power supply and i don't know whether i can just go to bestbuy and buy an ATX power supply or do i have to specially order it from HP.

Welcome to TSG!
In determining what size of Power Supply is required there are more factors to consider. Here is a site that will give you hard numbers to work with to calculate the size. After size is calculated I usuually factor it by 25% to give you some breathing room.
Also you have to make sure the Power Supply is AMD Approved.

hey i have recently purchased a geforce 8500gt graphics card and it didn't work so i posted it here, and they found the solution, it was the power supply and now i'm wondering is there anything i should look out for? i know that i should pay attention to the power supply if it supports pci express and the 20- or 24 pin molex connectors. is there anything else i should pay attention to? thanks!


A:Power supply

The brand!
There are plenty of generic power supplies out there where the manufacturer just slaps on a random name and ships out for sale.
You need to get a PSU from a reputable manufacturer. To name a few: Antec, Thermaltake, OCZ, Corsair, Cooler Master, Seasonic, FSP, Enermax, etc.
Thermaltake, FSP, and Cooler Master have some nice budget-priced units if you're not looking to spend too much.
I had a look at your other topic. Just make sure to pick a unit that produces the required output, and also to never buy an eMachine ever again.

My system has locked up twice now on me and only locks up later in the day. It's about a month old and my husband built it for me. Was wandering if these voltage settings were normal to drop or if I should tell him I need a bigger power supply.

make sure all the fans you have now are spinning. (Video card, CPU, power supply and case)

Did you build the system? What did you do about thermal paste on the CPU?

The power supply on my Dell Inspiron died less than six months after purchase.  The warranty provides for 1-2 business days service BUT the part is back ordered and no one can say when or if it will be supplied.  This is a mission critical computer for a small non-profit that serves children that have been abused.  Dell is worth 25 BILLION dollars.  The warranty, however, appears to be worthless.  We spent nearly $500 in charitable contributions to buy this Inspiron desktop ... and the best we can get for service is "if, maybe, or could be ... but we don't know when".  I would ask all community members to join me in reviewing Dell's warranty services, online, as utterly worthless.  I have purchased many Dell computers over the years for NGO(S) ... this will be the last.  What a disappointment!

I can't believe it. I actually managed to get an antec 350 watt power supply into an HP case. I had to remove the cdroms and bend the chassis but it is in.
The screw holes didn't line up, but that doesn't matter. The thing couldn't move if it tried. This was a rediculous ordeal to have to go through.
I'll never buy from the box folks again, this is a 2 ghz with 512 meg of ram and came with a 200 watt power supply. Man, what a rip. I am off to see if there is any noticeable change. I have just fired her up. Had to come here to complain before I did anything else.

I was given a computer that was not working, they said it just stopped, so I tested the power supply by jumping it and it did nothing. I had a lower wattage supply I tried and it still wouldn't start, although when I jumped it the fans started up. It had a 520 watt supply in it and I used a 250 watt to try it, would this affect it, or am I looking at another problem.

A:Power supply or?

If the 1st power supply failed, then there is a good possibility that when failure occurred it may have taken out the motherboard and/or other components.

hello guppies,

I just bought an AT power supply, it has four wires (2 white, 2 black) that goes into power switch.
How do I connect them. Can anyone help? The old ps had four wires, 1 white, 1 black, 1 blue, and 1 brown. Does it really matter, where I connect them?

A:AT Power Supply

Hopefully you noted how(where) the old power leads attached to the switch, primarily the brown and black wires. Any how, connect one black wire to where the original black wire was attached. Connect the other black wire to where the brown wire was attached. Connect the two white wires to the remaining terminals. (one to where the blue wire attached and the other to where the white wire was attached).


Just so you'll know:

Brown = 120 Volt from power cord
Blue = Neutral for power cord
Black = 120 V from switch to power supply
White = Neutral for power supply

Hope this helps.
