Computer power supply

The power supply seemed to be doing fine, running fans and such, putting out the correct voltage, etc. but when I put it back in the computer, the most it does is that once it clicked a couple of times.

I used a multimeter to check the voltages coming out of the big four pin connectors and they seem to be fine.

What could be wrong with it?

    The power supply that came out of the computer would only turn on for a second or two. It would output the correct voltage, and then go to zero

    The one I put in, I put the black lead from the multimeter into one of the grounds and then ran down the lines making sure the 3.3v, 5v, -12v, etc. were working and putting out the correct voltages.

Could be a bad component on the motherboard, not sending the correct signal to turn on the power supply. How did you test it while you had it out of the computer?

HP P4SD, its running good with 4 gb RAM, P4 3.0ghz, and a couple sata hd. The problem is the fan output voltage, i havent been able to read the output chassis and cpu cooler pins voltage cause i can find...


"i can find my dmm?" did you mean CAN'T?
"its clearly off", what is off?
the fans are 3 pins,2 are power, one is RPM tachometer.
"it all works fine", so you can boot and run any OS, ?

"the voltage reads +12vdc", where, at fan or PSU?
the fans run off 12vdc, they are DC motors (from outside fan)
if the fan runs slow at 12vdc the the fan is bad or is a low RPM
fan, as some are, bigger fans run slow, for less noise.!

first is the CPU fan it must run full speed, if not the CPU will overheat in seconds and ALL CPU shut them selves (by there selves) this way. so CPU fan is first. what does it do... there....?

then BIOS screens. GOT BIOS UP? and running? with, ESC key pressed>.
let me guess your symptoms
1: PC dead. will not boot.
2: BIOS dead.
3: all fans DEAD,.
4: power switch works and all PSU voltages read right, (seems not)/?
5: if the PSU power wire reads right(DMM), matching the side sticker voltages, and the CPU is dead, the MOBO is dead, or CPU is toasted.


here is a modern PSU, sticker.
see 5 to 10 power lines, see them. all must read correctly
if a fan is dead, then its dead if 12vdc is present on the fan power pins.

Note: I'm answering your post with the assumption that you plan on using this power supply with a computer. If this is not your intention, please disregard my solution attempt.

You likely already know this, but if you are powering a computer you're going to need a power supply with more wattage. I would recommend nothing less than a 350 watt power supply.

Follow this link to calculate how much power you need to run your computer: http://www.extreme.outervision.com/psucalculatorlite.jsp

If you're not ready to give up on your 270 watt power supply, then remove all PCI/PCI-E devices, USB ports, extra fans, non-boot hard drives, extra DVD/CD drives etc. one at a time until the computer powers up. Anything you can do to reduce the load on the power supply will help.

Good luck and thanks for using FixYa.

First, make sure you plug the power from the fan back into the motherboard & try it again. Did you do anything else besides just pulling out your old hard drive & putting the new one in? The CPU fan is completely independent of the CPU fan. You can start up you system without ANY hard drives & the CPU fan will come on if it's plugged in & the power supply is working etc. If you make sure the fan is plugged in correctly & the fan still doesn't come on, I suggest you temporarily put your old hard drive back in & firing things up. I'm sure you will find that the fan still doesn't work.

All that said, if the CPU fan isn't working (& everything else is), then it's a bad fan or motherboard. It's not necessarily a bad motherboard. Sometimes there are jumpers that control that sort of thing. I'm not sure exactly what that motherboard does. I have had this exact motherboard for years & as long as the fan is plugged in (& the power supply is working), when you start things up, the fan comes on.

One last thought, try flipping the power supply switch in the back to reset the power supply before you press the button in the front. Good luck...

Having never repaired, or seen an Acer Aspire L100 desktop, I went to Acer Support, and reviews on the internet. (I do repair computers, however, not just Googling info off of the internet here)

Seems the Acer Aspire L100, uses an external power brick for a power supply. Also looks like they're harder to find than hen's teeth!

It does seem judging by your findings, that your problem is the power supply.
A computer power supply put's out three main voltages, (Such as you have seen)
A.3.3 Volts
B.5 Volts
C.12 Volts

You obviously have a weak 12 volt power rail.
At this point I would take the power brick to a repair shop. I'll bet it's bad Electrolytic Capacitors, but this is just IMHO.

Also read where there are problems with overheating issues. Most post that the front door should be kept open, when using the computer. Better make sure the inside of the computer is clean, as well.

(Computer off, and unplugged from power. Use a can or two, of compressed air for computers.
Pay special attention to the heatsink under the processor fan, and the processor fan.
Do NOT keep constant air pressure on the fan. It is only designed to spin so fast. Spinning it faster than it was designed for, can lead to premature failure of the fan's bearings! {If you hear the fan go 'Zing' get the air pressure away from it!}

BEFORE you reach inside the computer, unplug the power from it. TOUCH the metal frame of the computer case, to relieve your body of static electricity. Static will fry out those delicate computer hardware components. You may not see it, or feel it!
Zap! There goes your computer!

Try to gently move the fan blades by tipping them. Looseness in this area means the fan bearings are shot. Replace fan)

My emachine shuts itself off, fan working ok, help help


Hi there. When you turn on your system, enter the BIOS setup screen. Depending on your BIOS, you may have a section that tells you the PC Health Status. If you do, you can check what temp your processor is, and it may even let you adjust the warning temp, (it may be set too low). Some BIOS's will shut down a machine automatically if this temp is reached, to save the integrity of the system.

Yes, you may have a faulty power supply. Try testing it with another and see if the same thing happens. Also, make sure that your power supply is connected to your motherboard properly. Easiest way is to just disconnect it from the motherboard, check for any bent/broken pins, then just click it firmly back into place.

If you need me to clarify anything, just post a comment.

Same problem... orange power light, fan starts slow and builds up to very high speed.
I removed my video card and SIMMs --> it beeped on boot and the fan did not speed up.
Put one SIMM back in --> booted fine, pressed F2 to view BIOS. Memory reported fine.
Put all SIMMs back in --> all fine now.

Cpu fan wont come on after new power supply put in


what made you change the power supply to begin with? Most cpu fans run off the motherboard, but the motherboard initially gets all voltages from the Power supply to begin wth. Did you assume that because cpu fan wasn't running to begin with, that the original power supply was bad. Not a bad assumption but one that needed verification before changing out a power supply. So it seems at this point that you have an unverified bad power supply, a possible bad motherboard, and a known good cpu fan. Plus at ths point you really don't know of the new power supply is good yet until you see something electrical run with it.
