PC restarts after playing games-is my PSU dying?

[Chris Redfield]

Hello everyone,

I'm playing The Witcher 3 for few days and my PC started to restarting while playing without BSOD,it just restarts.

I played for 4-6 hours per day without problems,but sometimes like today it restarts after only 30 minutes.
I know that may be dying PSU,but I ran OCCT stress test for more than an 3 hours and max CPU temps are 88c max while average is around 86c (I have very small case).
I haven't overclocked anything.
Here are my PC specs:Windows 10 x64
LG 27UD58-B
MSI Z97 PC Mate
Intel i5 4670K with aftermarket cooler (link below)

8 GB RAM
MSI GTX 1080 Gaming + 8GB
Coolermaster G550M
I can't swap PSU to check is the problem in it,so I'm using OCCT.

I even ran Catzilla because I heard it could be good for testing PSU,and it went fine.

I'm aware that my PSU wasn't the best choice for my GPU,but that's another story.

Is there anything more I can do to test PSU?

What do you think?

maybe run AIDA64 and stress all at once

 

or reinstall windows that could get rid of any software problems

What does the Eventmanager say?

Is this PSU still under warranty ?

I will run AIDA64 with OCCT,but I hope reinstalling Windows will be the last option.

Unfortunately not,warranty expired few months ago.

Well PSU is a first suspect, you need another one (decent) to test and confirm that.

Yeah,I know.Unfortunately I'm not available to get another one,and I won't be for next month or so.

I was hoping there's some other way to test it like some sort of stress test or software.

I looked at EventManager and here is the result:(pictures below).

I will try to stress test it with AIDA64 and OCCT both at once.

I ran OCCT at 4k for 7 hours and it didn't crashed.

However, yesterday it did crash while I was playing.

Do you have any advice?

[Chris Redfield]

I still have this problem,if anyone can help me,please do.

I wont be able to get new PSU at least for month and the half,so any help is more than welcome.

Downvolt the GPU.

How much should I downvolt it?

I never done that so I'm not sure.

Also,will downvolting decrease performance in gaming?

Until PC stops shutting down. It's temporary remedy, until you replace the PSU.

Yes.
