PC Shut Down Mid Game After New PSU Install

[xscratchnsniffx]

Hi guys don't know if you can help or not. the other day I brought a new gpu and that blew my psu up. so I brought a new one and Ive just installed it and tested crysis 2, and after about 20 minutes my pc just switched off like as if someone turned the plug off. it booted up fine. my temps where ok before my cpu was 40c and gpu was on 65-70c.

ASUS HD7870 CUii V2
CORSAIR CX750M PSU

under clock the video card. (this is one of those direct cu)?............... asus has quite a few of those that are unreliable.

sorry its not overclocked, just standard core clock 1000 and memory clock 1200. I think something may of got to hot i dont have lots of fans so i took the side casing off and have put a fan blowing towards it to air the air flowing.

it just did it again i started playing rust and after 2 minutes it shut down. i rebooted and it done it again, all temps were really low so it not that. im confused if anybody have an idea please let me know. ive spent £250 this last week on my pc and can hardly use it because of this.

the cpu on the card is the only thing that registers temps......... there are other parts that get hot.

what's your old card and what happens when you put that back in?

It seems to have stopped doing it now. I reconnected the psu and all's ok now. My old gpu was a 6670 so don't fancy putting that back in lol

the idea of your old card was to see if it still worked................. so you found the connections weren't tight. easy fix.
