Check a dead power supply?

Q: Check a dead power supply?

Is there a way to check a power supply besides plugging it in to your motherboard?
I cant tell if mine is dead or not, its a new case.

300w antec aria, 20pin (1 pin is missing a -5v connector, but Antec said its supposed to be this way). I plug it in and hear a little noise of power thats hard to explain.

The lights flickered on for a second one time, but i dont know why it doesnt like me
You cant plug in the Power connecter to the mobo wrong, its a 24pin on mobo but
20 pin fits fine, im doing it with other cases too.

Any idea?

I'm working on a 10-yr old HP pavillion pc. The pc would not turn on at all, monitor displays 'no signal'. the pc lights flicker. I had an older atx power supply and tried that- it worked. so I know that the old power supply was bad. the case was VERY dirty. almost all the vent holes were clogged. even after I tried my 'new' power supply, the cpu fan does not come on and I still get 'no signal' on monitor (the hard drive/cdrom drive DO come on). I'm thinking the power supply blew, taking the mobo with it. I don't want to spend alot of time on this, but can anyone offer any thoughts on this? thanks.

(Solved) Power supply dead?

My computer turned off by itself and I haven't been able to turn it back on since. I'm thinking it might be the power supply. 480w atx sata AG2 power supply. I pulled the power supply out, cleaned it and the inside of the computer, hooked everything back up but, still dosen't turn on. Could someone possible help me here?

I replaced the psu and now it's running. Thanks for the help.

A:Power supply dead?

If you can borrow one 480w or higher try it on your PC. And try your PSU on others too.

I just bought a Raidmax 735W LED ATX 80 Plus Bronze Certified Power Supply at Frys tonight. I haven't installed it yet, but when I inserted the power cord, plugged it in and turned it on, nothing happened - no fan, no light. Is that normal? Does it only kick on once it is attached to the motherboard and computer devices? Or did I get a dud? I don't want to go to the trouble of installing it if it is a defective unit.

I started my PC this morning and it booted as normal then after 30 second or so it turned off. I tried to start it and got nothing at all. I could smell something like an electrical burn. I pulled the power supply and put a jumper between the green wire and a black wire and the PSU did nothing. I had a smaller PSU not being used so I tried the same thing with the jumper and it started right up. So it looks like my PSU is dead. I hooked the older one that was working to the motherboard and got nothing again when I tried to start it. I am wondering if a power supply goes could it have taken other hardware with it?

The PSU and processor are 6 years old. The memory is 2 years old. The motherboard is 4 moths old.

A:Power Supply Dead?

Yep, if another PSU booted the machine, you have a dead power supply. I'd look at replacements with the same Wattage rating, but spend the money to get a good quality replacement, and don't buy the cheapest possible PSU. A crappy power supply can fry your system if it fails. You are much better off spending some extra bucks on a highly rated power supply than buying a cheaper unit that claims to have a higher output. Antec, Seasonic, Coolermaster, Thermaltake, Corsair, OCZ/PC Power and Cooling, and Sparkle are good brands. I'd avoid Rosewill, Diablotek, Xigmatek and "budget" power supplies in general.

We had a storm roll through late last week. Long story short, my pc was dead. Hitting the power button had zero effect. No lights no fans no nothing. I swapped outlets with the same result. I swapped power cords with the monitor, which was working, and the pc still didn't power up and the monitor powered up with the pc power cord. That narrowed it to internal to the pc. I put the hard drive in another machine and can view everything, so thankfully the hard drive is good. My guess is the power supply. Does that sound like a good guess to you guys?

It is a Dell Dimension 2350. I have heard and read that Dell ps are proprietary with a unique plug. The articles that I have found though are several years old. Is this still the case? I compared it to an HP machine and aside from the physical shape, the connectors look to be the same. My question, is will I be able to buy any brand ps and swap it out, so long as it fits this case?

Thanks a ton for any insight and info,


A:Power Supply dead...I think

you would have to make sure that the mobo and psu conform to ATX form factor, the plug that goes into the motherboard has to be ATX 20-pin, and of course your power suplly has to match the ATX ones in the local pc store, if I were you take out your dead one and bring it with you when you go looking.

I assume that my power supply has died on me. When I try to start my PC I get no power except the green LED light on my motherboard. I have noticed when I had my case open that when I push the power button on my case that all the fans in my system slightly turn but thats it, even the cooling fan in my power supply. The power supply is a 300 watt ATX and I wonder if I was underpowering my machine. My mother board requires a minimum 230 watt power supply and I have my hard drive, floppy drive, dvd-rom and cd-rw along with the motherboard and all of the cards pulling power off of the PS. My dvd-rom had quit working over a year ago, it would freeze up on me whether I tried watching a dvd or doing a data transfer. Also, I would have to push the open button on my cd-rw 3 or 4 times to get the drawer to open. I suspect that I may have been underpowered for the hardware I have.

Anyway, is my PS dead and if so, what should the minimum wattage I should get for the hardware I have? Thanks in advance for any replies.

Hello, I have been using a home-built computer for about 2 years now. It's been working fine, no problems. However, today, I was unable to boot it up. Do I have a dead power supply? When I turn on my surge protector (which has my computer, as well as my moniter connected), it seems as if everything works fine. My monither turns on, and my computer's modem light (on the back side) turns on. When I press my power button, nothing happens. I looked inside my case and there is a light on saying that my DIMM is functional, so it seems there is SOME power..but when I hit my power button, I see my CPU fan spin once, and then stop moving. WHenever I hit my power button after that, I get no response.

Is it time for a new power supply? Or could there be another symptom?

By the way, the power supply I bought CAME with my case..

A:Is my power supply dead?

Well it could be the power supply, or the front case power switch, or the motherboard, or another faulty component.

But you need to start somewhere. Youll have to either have the power supply tested or you'll need to get a power supply to test in your system.

hi all just turned on my pc and loaded it up fine when it turned itself off and won't come back on again. my psu fans been making a buzzing noise lately but a well placed smack seemed to shut it up. now when i turn it on it tries to spin the fan but dies. got power to the motherboard, theres some dust on the fan but it spins easy enough when i push it manually.

guessing the buzz was its screams for help and its now dead? got no other pc to try the psu from ether. so what i'd like is a rough idea if investing in a new psu would be the solution and if so which one coz i'm broke!

I just installed a CD-burner. Once I got everything put together I hit the power button and nothing happens! I assumed I had knocked something loose but I can find nothing. I installed this Mother Board so I know it pretty well. I can not figure out what has happened.

The only clue is that when I hit the power button I hear the familar pop of the speakers. The fan on the CPU twitches and that is it. Any clues as to what is going on? I am leaning toward a bad power supply but the fact that I just installed this CD-drive really makes me wonder if it is somehow related.

BTW I have tried unplugging everything to see if one of drives might be responsible. Double checked all conections and all the obvious things.

I am open to ideas!


A:Dead power supply??

I would agree kudzu. Your computer shows the same symtoms as a computer I replace the power supply in about 4 months ago. Most likely a burnt out capasitor.

As long as it burned out because of age and not because of a hardware falure, I think your safe.

Good luck

I went away for a few days and had shut the system off while I was gone. When I got back, I turned the system on and the power supply fan won't run. I'm using the system for very short periods trying to do some important stuff like making a startup disk (procrastinated far too long I know!) The question is this, can this be fixed, or should I just buy a new tower with a new power supply? My current tower was from the 386 that my system was originally (now it's a 300Mhz with Win'98SE).

Just to clarify further, when I turned it on to come here to ask the question, it booted with a CMOS checksum error and I had to reload all of my BIOS settings, auto detect harddrives, CDrom, everything. I'm assuming that was due to the complete failure of the system resulting from the loss of the power supply fan (and the dying breath of the CMOS battery which I know needs to be replaced since it loses time when turned off).

Need some wisdom. My computer stopped working, and wouldn't start would just keep going around it circles. We had a power surge, and yes I have a power surge protector.
I just bought a new tower, but now the old computer won't even turn on. As in when you push the power button, nothing happen. Not even the fans inside the computer start, and no lights come on. I know nothing about power supply to these things, but I have heard that they can go. Any wisdom on this subject would be great.

Did you check the breaker switch at the rear of the case on the supply? It sounds like
that simply tripped. If not, try a substitute supply to see if that is the actual problem.

My XPS laptop fails to boot and battery is flat (tho' it is old).
The power adapter is cold and has no light on it.
BUT if I disconnect it from the laptop and re-plug it into the wall socket the light does come on.
However when I reconnect the adapter to the laptop, the light on it goes off again.
I assume this shows the PSU adapter has failed.
Can anyone confirm this for me?

A:Power supply dead?

Sounds like the adapter is OK, but there's a short circuit inside the system somewhere.  Replace the DC power jack in the system first -- if that doesn't solve the problem, replace the mainboard.

Right i got myself a 600W EzCool power and it worked fine in my new gigabyte p31 mobo.
3 days later it turned itself off and would not work, I thought nothing of it went to bed and the next day it was working again.
However a few hours into the day it turned itself off a few more times, and eventually would not boot whatsoever.
Put my old 420W back in works fine and is quieter than what was meant to be a 'silent fan' that always ran quite loud.
Is there anyway to find out if the EzCool PSU is dead as it did not blow or anythin, it just refuses to work and the fan inside wont spin.
When i try to turn my pc on the fan on the CPU spins for about a second and dies but nothing from the PSU fan, any help would be appreciated thanks.

In a previous thread someone suggested it may be the power supply that the +5v line was broken and the +12v was okay.

My kids related a problem on the "kids computer", eMachine T2040 running XP. They related the computer CPU seemed to get very hot and got a funny, burning smell. Oh well, let's keep using it and see what happens. The power abruptly shut off and then they brought this to my attention.

I pulled out the power supply and found a fragged cooling fan and glue like substance oozing from one of the components. I bought a new powersupply and everything appeared to come back to life. Except the built in sound card and CD Rom now longer work. I rechecked the cord connections for data and power and they seem fine. The device manager shows yellow exclamation points next to sound card and CD rom drivers. Uninstalling them and re-installing them kills some time but has no resolution.

Question: could the high temp and sudden shutdown adversely affected and damaged the BIOS chip (where I presume the driver info is stored?)


A:Dead power supply and BIOS

The driver info is stored on the hard drive though.
You could check on the BIOS to make sure there is nothing disabling the devices, as the power supply failure could have caused problems.

You have to consider that the power supply failure could have actually damaged the devices or the motherboard though, as a prime cause.

I have a homemade system that just died. It has a Duron 900 that I know had been running hot (175 F). It also has a 375w power supply that also serves as a power strip. I removed the heat sink & fan to do some cleaning (spray air to knock off dust on the MOBO around the CPU). I broke one of the prongs on the socket that holds down the heat sink. A "friend" suggested using super glue to re-attach the heat sink. Now...nothing. The reset button lights up on the power supply, but the fan does not kick on and nothing else functions. Would a dead CPU cause this...power supply...MOBO...or a combination? Thanks for your consideration.

A:dead computer - CPU or power supply?

CPU sounds fried. Superglue? Really? I'd replace both the cpu and the board as you can no longer attach a heatsink to the board unless you have mounting holes and can find one that attaches with mounting holes.

Hi, folks.

During a recent power outage, I was running a portable generator through a power subpanel to power fridge, freezer, and a couple light and outlet circuits. I inadvertently shut off a couple of the higher load circuits without cutting the lights and outlets first, which sent a surge through the circuits still on.

My old HP a1210n desktop and all the peripherals and accessories were connected to a power-strip type surge suppressor, but none were powered up.

The power surge fried the suppressor. After the utility power came back on (three days later) I connected the monitor, printer, scanner, and sound system directly to the wall outlet and they all work fine.

The PC won't power up. Power supply is Bestec ATX-300-12Z Rev BD. Slide-type breaker on back of PS said "reset" and I slid it back to the 115 position. Still no power.

Pulled the PC cover and there's no obvious damage/smoke around the power supply.

Is there a trick to resetting the breaker? Are there additional breakers/fuses inside the unit I need to check?

If not, I don't know how to test to see if there's damage beyond the PS. Guess that'll be a trip to the repair shop.

Any ideas/suggestions are appreciated. Thanks!

The power supply died on my desktop pc (asus board with amd proc and windows xp home edition with sp3). Replaced power supply and eventually determined that even in safe mode it would
boot as far as mup.sys then reboot.
Running chkdsk from installation cd fixed it somewhat.

It boots ok now and makes it to the desktop with mouse and keyboard working but:
- no start menu or taskbar
- wallpaper and desktop icons are present
- during bootup several messages are displayed saying I don't have permission to change settings in catalyst control center (software for ati onboard video)
- can access/edit/view desktop documents created with apps such as windows notepad, openoffice and google sketchup
- can view saved .pdf files
- can access and view desktop folders
- cannot access files (mp3, mpeg) that use windows media player - nothing happens
- cannot access desktop shortcuts to websites or a saved webpage on desktop (.htm or .mht).
This results in error message "there was a problem sending the command to the program".
internet explorer is the default browser
- photo thumbnails appear ok but no viewer - can view/edit .jpgs with windows paint program
- taskmanager runs ok and will run msconfig, sfc, etc.
- it says Windows Explorer is running. Ending the task and restarting does not help
- ran sfc - it ran for 30 or 40 minutes then ended without saying anything.

For some reason, flicking the switch (in the uk they have switches to turn the actual socket on/off)a few days after I had decided to get some new RAM sticks, it must have 'detected' it as 110 volts (rather than what it should be, 220+ volts). The power supply, for a lack of a better description, 'blew up'. I was obviously extremely pissed off. Not only would I have to replace the RAM, I would also have to get a new power supply. Everything was plugged in and installed when it blew up. The machine was off when I flicked the socket switch to ON, and it blew up, a bit of smoke billowed out of the power supply, I knew it was dead.

So I ordered a slightly better power supply, a Corsair TX 650W (I had an NZXT 600W before), which also automatically detects voltage. I also ordered 2 2gb sticks of corsair ddr2 800 mhz ram.

let me reiterate that the computer was actually OFF when the power supply blew up / got fried / etc. not sure if it makes any difference, but it may be worth pointing out again.

so i put it all back together again slowly. the power supply goes in, the motherboard was already installed with the processor on it, the heatsink goes in... Read more

A:Dead hardware due to Power Supply Malfunction?

When a power supply blows you have to check each component individually. I've seen blown power supply's only take out the board and everything else was fine, and i've seen power supply's blow and take out everything.

If you don't have diagnostic equipment/parts to change out take it to a shop.

My dad said he came home the other day and smelled something "electrical" burning and traced it to the computer, so he unplugged it.

I plugged it in to test it, and got a loud horrible sounding beep (so loud i'm not sure if it came from speakers or the hardware??) and then nothing happens Won't boot up. I just hear a vibrating/sickly humming sound in the box that is in the back of the case, with a fan, and as far as I can tell the fan is still spinning, so the noise most likely isn't the fan. Would this 'box' be the power supply? I am guessing so since this is where the power plug goes in at. Also, if it is indeed the power supply, would this problem inflict damage on other components?

my laptop is a packard bell dot (same as the acer aspire one zg5) equipped with a hannstar j mv-4 94v, I disassembled it to fix a wireless module problem, then when I assembled it back and put on the battery the power and charge leds flash for a second and nothing happens when I try to power it on.
same reaction happens when I plug on the power supply or put on the battery.
even the battery doesn't seem to charge anymore (its indicator just flashes for a second as I said)

here's a video:

any help or suggestion?


A:Dead netbook except leds flash once when power supply plugged

One of the ribbon cables may not be securely connected. Them things are a pain to deal with.

If you hadn't previously worked on it, I was going to suggest the power supply may have gone bad. Since you worked on it and that is when the problem started, its been my experience the problem is nearly always workers error.

I left a 3-year-old Compaq desktop computer at my summer camp last fall. Apparently, the cold temperatures got to it. When I returned recently, it was completely dead. No pilot light, HDD spinup or fans. Checked power at outlet, replaced power cord and verified switch continuity. All OK.

I remember from years past that power supplies typically contain a “power good” circuit that totally shuts down the supply if any voltage is out-of-spec. Assumed stiff lube in a HDD might be stalling the motor and overloading the power supply. Disconnected power from all drives, removed PCI cards and disconnected all USB cables. Still dead.

I borrowed and installed 2 used power supplies both of which are believed (but not known for sure) to be good. Neither produced any change.

Thus I am assuming that the motherboard is bad and overloading the power supply. Before jumping to that conclusion (and probably junking the computer) I would like to verify the power supply is OK. Don’t have another computer to try it in.

Does anyone know pinouts on power supply connectors? I’m assuming a small load (say a 1K resistor on each supply) and shorting the power switch leads should make a good supply operate. Is that correct?

Thanks for any insight anyone can offer.

HP Officejet 7210 Printer stopped after power supply removed during shutdown
My HP 7210 OfficeJet all-in-one printer stopped working after I removed the power supply in the middle of a power shutdown. No functions including the fax, printer, scan and copy work. The display is dead, and there is nothing lit or working on the printer. Is there any combination of buttons to press on the keyboard to allow access to a troubleshooting menu or reset? Or, any other suggestions to fix it? I tested the power supply for correct voltage and it is correctly working. Windows XP sp3, direct connection to PC.

A:Power Supply check

Hi Panais,

No software that I know of, you can use a multimeter to check voltages on the various lines and thus work out current draw on the PSU and thus the power.

The easiest way is to add together the power "wattage" rating of each of your components (info should be available in documentation or on manufacturer's web site) a total of all the ratings at their highest load figure should give a worst case figure which should be less than your rated peak PSU output. The total of the "normal " Load figures of all the components that are working at the same time should be less than your continuous rating for the PSU.

This is of course an exercise based on quoted figures each component is different and also may vary over time.

Is this a general question or do you have reason to think the unit may not be upto the task?

I have an older computer that was acting up and completely shutting down every 20 minutes, and now it rarely will start at all. I was wondering the best way to check to see if the power supply is burned out, or if there is another possible issue. I have a voltameter for testing electrical stuff, but want to make sure that I don't do something really dumb!! Thanks for the help!
