Hello, I recently just bought a evga geforce gtx 660 graphic card. my old card was a geforce gt 220. I put it in, and everything goes fine. Then i ran the windows experience index thing and after like 5 seconds the computer shut down and when i restart it beeps and says it shutdown because of a thermal event (cpu overheating).
so I downloaded core temp and speed fan, and did it again, and the temps were all fine when it shut down. the gpu was at like high 30's and once the cpu got up to like 50 is when it crashed. but i put my old card back in and ran the same thing and it got up to mid to high 60s with no problem and didn't shut down(gpu temp was fine as well, i think it was around like 40 or something)
So i don't really think it has anything to do with temperature at all, cause even if i run the experience test as soon as i start up the comp it still happens after 10 secons, so i dont think it would have time to heat up that much, and why with my other card in would the cpu be able to go into the high 60s c but now with this one it shuts down at 50? and i can start my pc up again right away and the temps are at normal.
So i was thinking it might be that my psu isnt good enough? the geforce website says that for a single card 450w is enough and my psu is 450w, but I can't really think of any other difference between the old card and this card that would cause this.
(the old card doesn't plug into the psu but the new one does. the new card has a 6 pin connector that splits into 2 molex connectors, and i connected both of them in.)
my internet on that computer is messed up and cuts out every 5 minutes for some reason right now so i havent been able to download any games but basically i think it would happen with a game to, i think as soon as i run anything that requires some muscle like the windows experience test it shuts down within like 10-20 seconds. but if im just browsing the internet or anything it works fine.
so does anyone else think it might be the psu? or what else it might be? i wanted to ask here before i went and spent money on a new power supply.
