Hello, my system recently shuts itself down completely.

CPU: 10 5800k

GPU: gtx 550 ti

MB: GA-F2A75-D3H

PSU: Cooler master 400w

When playing games after like 0.5-2 hours the pc shuts off. I bet it's the power supply overheating since I can't turn on the pc right back when it shuts down (only after 1min or so)...

 

Edit: Did a 15minute run on Furmark on the gpu and it shut itself down after 6 minutes, could it be that the psu is too bad (400w) for the gpu?

had the same problem with my a10 5800k too, it turned out that i activated my turbo mode in the bios (3.8ghz - 4.2ghz) and i think my PSU (corsair 650 tx) cant handle it or my pc ventilation is horrible so i deactivated it.. and it worked great again..

That wasn't my problem, it turns out my PSU only delivers 18A on the +12V rail, and the gpu needs 24A+ for it to function normally. Also I've read that with low Ampers your gpu will hog all the power and will not leave some for the HDD, so the HDD will die very soon cause of that
