Windows 7: Failing PSU?

Failing PSU?

My computer will automatically reboot from complete shutdown after about 30 minutes.

Googling the problem, says it might be a failing PSU.

Can someone read this chart and advise if the PSU is going bad?

Thanks,

Paul

I can't tell anything from that info.
Do you have a multimeter you can use?

To clarify: you turn the PC OFF (not sleep, not hibernate) and approx. 30 minutes later it starts all by itself?

Go into the BIOS and see if Restart on Power Loss is set. If it is, disable it. You may have some power drops or brown-outs that could trigger a start. Is your PC on a UPS?

Couldn't find such a setting.

Not on UPS.

Called thermaltake and they said it probably is caused by the hot swap bay (built-in to Case), some sort of of conflict. They also said the PSU might be failing.

If I disable hot swap controller in BIOS, the problem disappears, but I NEED the hot swap and would just as soon put the computer to Sleep.

When I ran Powercfg -devicequery wake_armed- it said USB controller.

The wake options shouldn't turn the PC on. Those are started from sleep states. Are you on an administrated network? (Work PC)

Speed Fan is useless. Download and run HWiNFO64. Post an image of the voltage area. You can also set it to log for a while to capture a history while you do other things. If the PS is weak, it may show wide swings in voltages.

Forgot to mention: Do NOT run more than ONE monitor at the same time. Disable Speed Fan while running HWiNFO64.

That's not the temperature/voltage area. You need to show the sensors window.

It will look similar to this:
