How to Tell if my PSU is Failing?

post #1 of 9
Thread Starter 
I got a new computer. It's custom built and arrived in the mail yesterday.

Since then it's been shutting down randomly. The computer would close windows and just shut down.
Specs:
8GB DDR3 Ram
FX-4100
6770 GPU
500 Watt PSU

Is the PSU failing or what?

It could be, especially if it's shutting down / crashing when the computer is under load. To test your PSU, you will need a Multi Meter to test the voltage output of your PSU.

Here's a link on how to do this if you are unaware.

From what you are saying it sounds like the computer is shutting itself down maybe to protect itself

Have you checked temps?

Or maybe it is something like a faulty power button on your comp?

I had a PSU do exactly that, It's the PSU (If it isn't temps). What do you have currently? I had a Xigmatek 600w do that, replaced it with a Seasonic S12II and it's been perfect since.

I'm pretty sure it's a low quality 500W.
Ram is fine. I checked it on different computers. I'm loathe to take out the power supply and check that with a different computer because of all the unplugging. T.T

PSU isn't under load when it crashes. I'd use my computer normally and it'd sometimes crash on startup or after use for a while.

Not overheating. tongue.gif Made sure of that. There's a GPU, CPU and PSU fan a case fan, one fan over the HDD and a fan in the back. CPUID shows temperatures of CPU at 25-32 Celsius for the CPU and 33-34 for the GPU. HDD holds at 32 constantly.

Does it abruptly shut off as if someone pulled the plug or is it more of a shutdown sequence? If it's the former, it could be a symptom of a dying PSU.

Unless a PSU is over-heating or has low voltages it's pretty difficult to determine it's status. The PC shutting off could be any number of things including but not limited to the PSU.

Computer just shuts down as if I were holding down the power button.
It's really annoying D:
Replacement PSU should arrive in 2 days. If that one doesn't work I guess I can dish out another $50 for a decent 80+ PSU or figure out whatever the heck else is wrong.
