How do I tell if my power supply is faulty?

[Kitten of the Broccoli]

My issue with my computer is fully explained here: 

From what I can find out, it's likely the power supply is causing my computer to crash the way it is, but nowhere else am I able to find anyone recounting how their computer screens go black and the power and reset buttons stop working. Can anyone else confirm this theory?

It's not the PSU. 

 

NONE of what you described points to the PSU.  If anything, the motherboard is bad.

If the power button stops working as well, it points to the motherboard.

When you said none of your USB ports were working did you check the ones on the back with that are directly connected to the motherboard?

My keyboard and mouse are connected to the back, and they both lose power.

WAIT 

 

I had that board. You probably have an old BIOS. I had that issue but it was fixed with the 3401 BIOS. It usually happens a lot more with overclocking.

Well then that eliminates the case connections, honestly as they said above it is likely be the board, the PSU can cause somewhat similar issues but normally in the event of a PSU failure the system will either shutdown completely or blow a part breaking the computer beyond the initial issue. Advice given above is nulls what I was writing beyond this ^^^

After thinking back on it, I DID start having this issue while I was overclocking about a week and a half ago. Also, I already DID update the BIOS, and when I go to try to do it again, it tells me that I'm on the latest version already.

You probably need to up your SOC voltage. On that board you can set it up to 1.2V so try setting the offset up by .3125V to start with, and if that doesn't solve your problem then go up to +.5.

I don't have the overclocked applied right now, though. That's the issue. It does this even when running completely stock.

Is your RAM running at DOCP speeds?

It was, then when my computer started locking up, I disabled it, but when it still kept doing it, I re-enabled it.

After you reset CMOS and do all the same stuff again, does that solve it?

 

Supposedly running both HWInfo64 and Asus AI Suite at the same time can often cause that. Perhaps try uninstalling AI Suite.

I'll keep AI Suite disabled, but I did have to clear CMOS after the trying to overclock and the only options that I have changed since are DOCP and certain options relating to networking.

Check that for all the various issues that board faces. Mine, especially with any BIOS after 3401, had tons of issues with getting RAM to run at higher speeds.

That thing the one guy said about getting black screens and only being able to fix it is by physically cutting power from the system makes me even more certain that it's a problem specific to this motherboard and that I should just get a new(different) one.
