Horrible performace possibly the PSU to blame?

post #1 of 4
Thread Starter 
I have a close friend who I play games together with on a regular basis that has a problem. It started out awhile ago and it has become worse. I tried to help him trouble shoot and he has since upgraded his GPU for better performance but the problem is that after say one or two hours his frames drop to single digits. I have looked at his CPU temps and usage and everything is fine. After he restarts his computer the problem goes away for a short period of time. He has a Corsair HX850 PSU so power inst the issue. I was just wondering if the PSU has become the culprit and if their is some way to check if that truly is the problem.

I'm going to bet the GPU is getting too hot and is down-clocking itself to prevent overheating.

He has monitored his GPU temps, nothing over 75 degrees.

best way to find out would be to take a psu tester (around 15$ at a pc shop) and check the power flow on the pcie rails. I wouldnt bet on it being the power supply though, i would think that the GPU might be a little on the defective side. Ive seen a 680 barely handle occt (talking .49 fps). Card was defective, RMA'd and when the new one came it was going great.
