Pc shutting down. Gpu/Psu problem?

[ogzozcelik]

Hi.

Im having a problem with my pc. I had an old system that randomly crashing and restarting as if someone pulled the plug. It started to repeat it more frequently so i decided to buy new cpu, motherboard and rams.


I only kept my Gtx970 Asus strix gpu and psu xigmatec 650W silver.

I installed everything and launched system. Updated the drivers etc. Then i tried to lunch games, when i launched a game pc shut down as if the power is gone.

When i tried to restart the system the fans spin for half a second, and goes down, pc doesnt boot.

I replaced the gpu with my old Sapphire 4790, same thing.

When i wait a bit and reinstall everything pc sometimes starts normal. Then i launch a game in windowed mode, watching the temperture same time. It crashes in a couple minutes again while the temperature is at 65C.

I suspected overheating but 65C should be ok i guess? It shouldnt shot down at 65c as far as i know.

If it is the psu then why it goes for a while then shots down?

Cant be anything else as i bought them all new yesterday, all but gpu/psu and the ssd.


Another thing is when pc fails to boot (fans working for half a second then stopping), i unplug the pci power cables off the gpu, then pc starts normally.

If i remove gpu and plug the onboard gpu, everthing is fine.

Is this about the Psu? If so why is everthing ok without the gpu..

Specs;

Intel I7 7700
Asus Strix gtx970
Hyprx Predator 8gb 3000mhz
Asus b250f gaming motherboard
Xigmatec 650w silver

Sorry for long post/bad language.

It could be a PSU or GPU like you said, but did you try a different plug in the wall?, if it still proceeds it's probably a PSU problem, and i'd get it RMA'd if you have the warranty still.

Changed the psu with corsair tx750, everything is fine now, it was psu. Thanks for reply.
