PSU beginner question

post #1 of 7
Thread Starter 
Hello,

yesterday I bought EVGA G2 850W and surgearrest APC perfomance edition. When computer was on I forgot to plug in audio cable and I accidentally moved PSU cable and computer instantly turned off. Can that do any harm to my computer? Also are these voltages OK for my PSU:

+3.3V 3.264 V
+5V 5.036 V
+12V 12.149 V

For your computer - No. For Windows - Yes.

Plus or minus 10% is tolerable, 5% for overclocking though.
Check the voltages when the computer is under a heavy load. Volts at idle means nothing.

The program HWMonitor will monitor PSU voltage on most motherboards.
But best way to do that is with a digital volt meter. Just check the voltage at any 12 volt power connector (under load).

There is no diffrence in idle or load. +12V sometimes is in idle 12.098, sometimes 12.145. So EVGA quality, nothing to worry, everything in super condition?biggrin.gif

I don't understand. Are you saying idle volts varies from 12 to12.145?
Or something else?

LIke I said, the PSU isn't gong to show itself having a problem when it's hardly doing anything.
