Recently i decided that after 5 years it was time to upgrade my pc. After looking at my build at the time i decided to keep my case, PSU, and hard drive. Ive gotten it built and everything works like it should (i believe), but now ill start to play a game like fallout and after 15-45 it shuts off. ive ran speccy to check temps and they are all below 100° consistantly, but the CPU will fluctuate from 50-80° even when im not running anything. I have 5 fans and a giant cpu cooler so i dont think its a heat issue, but power instead, so i ordered a new 750W. Is there anything else it could be? Or is it most likely a power issue? Please help.

Specs as of now:
Gigabyte 990FXA-UD3
AMD FX 8350 8-core 4.0Ghz
Geforce GTX 770 2Gb
Xtreme Gear 600W ATX
G.SKILL Ripjaws X Series 8GB 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900)

Hi,

I'm willing to offer an opinion - it's worth what you're paying for it. :)

Have you checked that the CPU cooler is seated correctly? Could be a loose seating on one pin.

Have you tried running PRIME95 for an extended period to confirm stability?

It could also be a faulty component. Bad Video card, ram or cpu COULD cause this problem, AND: Did you install the cpu cooler properly? AND: Your CPU is a power hungry sob. It just might be that you will need that 750 watt PSU.

im 97% sure that the CPU cooler is attached correctly, i dont really see anymore fluctuation. i ran Prime95 for a solid few hours with no crashes, now im running FurMark to check my GPU, and when i find a disk i can burn i will run MemTest86+.

About 1 minute after starting to run FurMark my PC shutdown, i was watching the temp and it hardly went past 100 degrees, gunna re-seat my GPU and double...no triple check everything is plugged in properly and then try it again, if it does the same thing will that mean that its a PSU issue?
