Hi all need help my pc keeps saying cpu over voltage error i have a new psu its a evga gq 650 my motherboard is a P5G41T-M LX3 and my bios version 0503 i checked in my bios by hardware monitor the readings is as follows

Vcore Voltage - 1.424 jumping up and down to 1.392V

3.3V Voltage - 3.360V

5V Voltage - 5.632V in red color jumping up and down to 5.555V

12V Voltage - 13.464V

The cpu isn't overclocked.

Any help would be aprecciated.

check with a volt meter any of the 24 pin atx 5v lines if there over 5v return the power supply the 5v readings it too high.

Those voltage readings are too high. Your PSU is most definitely faulty, and if it isn't that, then your motherboard is.

To confirm it, check your PSU with a volt meter.

Ohk thanks i have a multimeter will quickly switch of pc and test the psu, how exactly can i test the psu 24 pin connecter? Must i test each pin bottom and top for example positive of multimeter by top rail and negative by bottom rail? And what voltage must each pin give me?

You can google PSU pinout btw.

thanks for the reply ive looked around for vids on how to test psu and they say psu must be running while testing ive seen a video where a guy uses a bend paperclip on two of the rails, like I said my psu is still brand new like 3mnths old I'm just worried to do stuff like that with paperclip etc and something happen and the guys don't give me refund back. my psu is also a modular and other vids show color coded wires on psu mine is all black wires. but like I mentioned I cant think that the psu would be the problem still it isn't impossible to happen

how can I test MB to see voltage etc? or not possible? I noticed also my pc was switched off for a fer hours and when I plugged the 24pin connecter on motherboard and booted pc up it showed me nothing of cpu over voltage error
