My 350W ATX power supply is running hot at 45°C when the pc is idle and whenever i play cpu-intesive games, it plays for about 5 mins and then the whole pc restarts. This is not a game specific problem, it even does it during cpu-intesive apps like TMPGEnc. Its whenever the cpu is at 100% load it does this. The cpu temps are fine, so is temps for the motherboard, hdd and gfx. I am thinking that perhaps i have too much hardware for a 350W psu to handle and am overloading it.
I have a qtec 400W dual fan psu that i can put in it's place. do u think that'll help?
