How to check a power supply

Q: How to check a power supply

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!

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.

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?

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.

I probably need to replace my power supply in my computer with a more powerful unit. How do I find out the output of my current ps?? Are they difficult to replace yourself or should a pro do it??

A:How do I check the specs of my power supply?

If your Dell computer was manufactured after August 1998, it may require the use of a proprietary Dell power supply. Although the Dell power supply looks like a standard ATX, it is a non-standard PSU that cannot be replaced with a standard power supply alone. Because of this design difference your Dell Power Supply may need a Dell to ATX power supply converter in order to be replaced with any standard ATX Quiet Power Supplies.

Pentium 4 Dell Models that do not require a power supply adapter:
Dell Dimension 4300, 4400, 4700, 8200, 8300, OptiPlex GX 400

Pentium 4 Dell Models that are not compatible with this power supply adapter:
Dell Dimension 8100
http://www.endpcnoise.com/cgi-bin/e/std/sku=dellconverter
open the case from the side
Remove 4 screws on the back of the power supply
Unplug everything from the power supply

Reverse the process your done. No real big deal. just make sure you know the power supply you purchase will work with a dell or the adapter you but with the power supply will work as well.

How do I find out the output of my current ps??
Look at the lable on the power supply it will tell you.

Also whats involved in replacing the cooling fan yourself?
Depends on what fan you are speaking of? the case fan? not much just remove it and replace. if your speaking of the cpu? a little more in depth, the stock heatsink+fan usally work and no reason to change unless overclocking.

I turned my emachine T2825 desktop off to move it. I plugged it back in and tried to turn it on but now it does not boot up, nothing on the screen. The blue indicating light around the power switch does not come on but the hard drive amber light is on and the processor fan is on all the time. I have been reading several threads with simliar problems on this PC and it sounds like the motherboard went bad and it is possible the power supply caused it to go bad. I have check my voltages and I get the 12 and 5 vdc at all my plugs. I have replaced the power supply with another 250w P.S. but it still won't boot up with the same results as before. Before I invest in another mother board I would like to make sure the power supply is bad or not. Is there a check for this? Also do these syptoms indicate a bad motherboard?

Thanks,

A:How do I check power supply on an emachine T2825

I would have to agree that it sounds like a bad motherboard...make sure that everything else is SEATED correctly, especially the video card.

You can get a 15 dollar tester from a computer store that allows you to test the P-Supply...Otherwise, you might google on home ways to test it.

I have 2 failed Z800 power supplies (1150 watt version). After some internet research I am led to believe this is a common problem and related to the PS capacitors. Since I do not know how to do this capacitor replacement (yet). I thought I would buy a new PS. However, I do not want to buy a Z800 PS since it seems to me to be a defective design. Can anyone chime in and tell me if the new z840 1125 watt PS will work with my older z800? I have called HP support and spoken with the correct support people on this and they were not able to confirm if the Z840 PS will work (fit) on the z800. The closest confirmantion I recieved was that if it fits then it should work. Instructions to fix the capacitors:http://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Z800-power-on-issue... Same issue I am facing:https://www.youtube.com/watch?v=f563JGeoxaw On a side note, can anyone recommend a good service tech to make such capacitor repares in Southern California or insrtuctions on how to make this repair (with pictures). Thanks

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!

Hi, so I have had a powering issue with my previous power supply which was the Corsair CX600W so i purchased a newer power supply - the EVGA SuperNova G2 550W. I unhooked my old psu, hooked up my new one and the PC turned on and I turned it back off from the power button on the case. I also hava a boot drive problem so I unplugged the sata cables from my SSD and wanted to try to turn on the PC with only my HDD. I did this with the PSU switched off and the power cord unplugged. When I tried turning the PC on again the PSU made a clicking noise and nothing turns on. The motherboard Led's are lit up so it is definitely getting power but when I go to turn the computer on it just makes a quick clicking noise and nothing turns on. Any help is appreciated, thanks!
 

A:Power Supply makes clicking noise when I press power button

You may just need to drain the power off from the power supply and try again. Unplug the power to the power supply, press and hold the power button for 30 seconds, then plug it back in and try to turn on the computer again. If that doesn't put the old power supply back in and see if the PC works, or was the old one dead? If the PC works with the old one and not the new one then you may have gotten a faulty power supply.

AMD Phenom Black Edition 9850,
4 gigs PC 6400 ram (Corsair XMS2 CM2X1024-6400
ATI Radeon 4870

The problem is that the motherboard will NOT power up at all with the 2 of the latest power supplies (600 watt+) i have.

It wont work at all with; (Nothing happens its just dead)
Arctic 600 watt Jeantech PSU (brand new and working)
Corsair 620 watt HX PSU (working)


It only seems to work with my Jeantech 450 Watt PSU and i cant for the life of me figure out why. Ive tried everything to get the board to work with the new PSU's. I had thought that the PSUs i got were dodgy but after testing out one in an older PC it worked fine.

Ive removed all parts and tried powering up and i cant get it to boot up. But the PC seems to work fine with the oldish 450 watt PSU which i find just unbelievable.

Can anyone help with this nightmare? Now on the Gigabyte site the CPU i have isnt listed as supported by this motherboard which is kinda worrying could this be the reason? If so how the old PSU boots up.

I just want to have the fracking thing working with the right PSU.
 

A:Power Supply Wont Power up - Gigabyte ga-ma790fx & AMD Phenom 9850

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'm interested in the Toshiba G25 laptop but have heard that you can't use it on airplane seat power. It comes with a 120W AC power supply (15Vx8A), but I've been told that most airlines limit seat power to 75-90W max. Lind sells a 12V car adaptor for the G25, but specifically won't include an airline plug for this reason (which I can get independently, of course). I've read some interesting electrical discussions on this board. Can ya'll comment on the following or provide any general advice about power consumption?

1) Given that the voltage of the laptop and airline seat power pretty much match up (12-15V), if the amp draw on the laptop exceeds what the airline power supply can deliver, what will happen? Will it damage the laptop to feed it insufficient current? Will it shut down the laptop altogether? Merely dim the screen?

2) If I remove the laptop battery, which requires power to charge it, how much will that reduce the power need of the laptop? I'm not sure how to work the math, but the spec sheet states the battery supplies 4400mAh at 8A output. Does it require the same to charge it?

3) Most importantly, on my 15 hour transpacific flights, will the DVD player work with that ultrabrite screen at the low airline power supply?

Hi,

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.

I have just bought a Dell 19.5 V 90 W power supply adapter for a Dell from ebay. The PSU turned up this morning without a power cord. That's annoying enough but when I looked the connector needed is a type I have never seen before. The centre pin is slightly longer and wider than the other two so I assume that is the Earth pin. The centre pin is also offset between the other two. Again I suppose for connecting only 1 way. The two outer pins have a distance of just under 2 cms between them. Please can anyone tell me what type of connector this is. If I can get some info on it then I may be able to get one.

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.

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.

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.

Hello to the HP community. I must warn you all, this is a long thread and is potentially confusing, so only read this if you're interested in giving feedback. I am here today to not ask a question, but to share with you my confusion on your Pavilion desktop PCs. I've looked at the technical specifications for many of the Pavilion desktops, including my own, and I simply can't understand one thing; where do you get your PSU power ratings from? I currently have a Pavilion 500-319na: http://support.hp.com/us-en/document/c04343438.It's a good computer, powerful in most areas although the GPU isn't, so I'm looking to upgrade it. The first thing I check before I upgrade parts, and hopefully others do too, is the PSU's power rating. And this is where my problem lies. Firstly, your website states that for my PC, and others, it's an external power adapter. It simply isn't, as it's inside of the PC. I've seen in many discussions that this has confused people, including myself. And secondly, your website states that for many of the Pavilion PCs, including mine, the PSU is rated at 180W. Let me tell you why I believe is wrong: The PSU that comes with my PC, and presumably other Pavilions too, has four power outputs: 3.3V (12A) and 5.08V (10A) outputs, 'limited' at 70W. Then there are 12Va (7A) and 12Vb (10A) outputs. These apparently produce 180W. First of all, the 3.3V and 5.08V outputs can't be limited to 70W, in theory. This is because, using the equation...

I have it hooked up like this, two Optical Drives connected to 1 IDE connector/cable which is hooked into the IDE input on the motherboard, both are set to slave. Two CD outs (connected one to each Optical Drives) to one CD input on the motherboard. Both HD's are connected to SATA inputs on the motherboard, one is set for master, one is set for slave (I heard that it did not matter but wanted to state that anyway), then my ATI RADEON X1950 is hooked directly into my only PCI Xpress 16 slot.

Also, I have my power running through a Monster Power HT700, I live in a new apartment so the wiring should be ok, I've dusted out all of the components inside the case, double checked my connections, all that jazz. I've got a cooler over my memory, I am still using my stock cpu cooler, but thats changing soon (I get crashes @ idle too) Any help I could recieve I would appreciate, thanks

A:Hardware Power Consumption-Picking a new Power Supply

You have pretty much the same problem as me (getting BSOD's randomly). For me it's bulging capacitors on motherboard. You should take a closer look for capacitors on your motherboard. Dead capacitors look something like that:

Yea...so we finally got my girlfriends new PC up and running. The problem im having...or more of a concern really. Is when you flip off the power supply, and then flip it back on, the PC gets a short burst of power. IE the lights and fans all come on for a second or two. Then you can press the power button and turn it back on.

Any ideas guys?

I shut down my Pavilion Elite for 1 week while away and now it will not turn on. The power supply light is on, I replaced the CMOS battery and the power switch is ok.

A:Pavilion elite power supply light on, won't power up

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?

Several months ago I upgraded most of my PC.
ASRock Z370 Gaming K6
i7 8700k Coffee Lake
Team T-Force Vulcan DDR4 2800 (16 gigs)
EVGA Geforce GTX 970
2tb SATA hard drive

This was all running on a Corsair 500 watt power supply. Now a couple days ago I decided it was finally time to upgrade, so I bought another 16 gigs of the same RAM listed above and a Seasonic Focus+ 750 Gold power supply. (I think) everything is hooked up the way it should be, only now it's sounding like my hard drive doesn't want to turn on. It'll make a whir like it's trying but then it just makes a sound like it can't turn on. I'm assuming this is the problem because my motherboard can't detect the hard drive, and it's still plugged in the same spot I had it originally when it was working. I believe it was slot SATA3_0_1.
Faulty hard drive? Or hopefully I'm doing something wrong so I don't have to screw with returning it.
Any ideas would be warmly welcomed!

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!
 

A:Laptop gets no power, power supply seems to be working

The charging circuits on the laptop motherboard may be shorted...

So I hooked my pc up after I took it w/ me to work becuase I though I was going to a lan tonight. But when I came home and plugged it back. I noticed the power supply box light was blinking. And it wont turn on. No power or what so ever. I need help BADLY

Thanks

Have you opened case to make sure all connections are secure? Something may have come loose while you were transporting it. Give us more info about your computer (e.g. make and model, cpu, ram, name of psu, etc.)

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.

Help!?!?!

Thanks,

Hi everybody,

I tried to search on google about this, but it's not really help and it never happen to me before so I post here.

My PC was running normally for a long time, just couple weeks ago I sent my faulty video card (xfx nvidia 8800 ultra) to get warranty service and they sent me back another. The new one works fine, but a week later I tried to turn on my computer and there's no power at all. No lights on, no fan running, just no sign of power. So I check inside if there's any wire from the PSU is unplugged, but everything looks good, nothing seems wrong. I'm sure the power from the wall is good and the power switch on the back is on. So I tried to check the wired again, push the power cable to the mother harder and press the button, it worked. But that doesnt solve the problem, if I put something heavy near the PC or the desk is vibrating a little bit, the power turns off. I press the power button again it would not turn on until I open the case and press the power cable to the motherboard harder, it's on. I then close the side panel, it's off, no power.
This is really annoyed me, I dont know what else to do. What caused this problem? The power supply or the power button? Can somebody help me?

My system specs:
ECS G31T-M mobo, Intel E8400 Duo, 2x2GB RAM
2x2 SATA HD, nVidia 8800 ultra video card
ULTRA's 1000watt PSU

Hi,
I'm currently a computing student so I rely 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 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
 

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.

I have a server that I would like to upgrade to 20 1TB Hitachi HD's. They claim max startup current of 2A. and idling down in the .5A range. The platform will be a 775-series X48 with a 6600 Core Duo. Graphics card is small, does not even require aux power connector. Not needed to just supply the KVM with 1280x1024. No other signficiant sources of 12V drain exist other than the MB/CPU, a slim CD-Drive for installs, a slim floppy, and one additional 30GB SSD startup drive (2W when active).

I am looking at an 850W Corsair. I've heard these are quality supplies and I don't want multiple rails since no one really knows what sort of Voodoo goes on as to how they divide multiple rails up. And I don't want to get into that. I will be using a single-rail +12V PS. I can add a second if I need to but I'd rather not.

Do you think this will be sufficient for handling 20 Hitachi hard drives? "Green" drives are a non-starter since they will drive my Raid 6 controller, and then me, off the deep end with TLER issues. I do have staggered spin-up control of the drives with the controller.

Thanks for any help.
 

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.

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 came with an Okia Model 500-ATX power supply.
But no wiring schematic.

I'm trying to identify the power supply fan plug - what 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 3 pin connection. The only thing I
can find that might be the fan connector coming from the
supply is a small 4 pin plug at the end of 1 of the 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.

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
