PC Just shuts down while gaming

[HashtagGrandpa]

So I built a system and it only shuts off during gaming. it doesn’t bsod or reboot, it fully shuts down and requires me to unplug the psu before restarting. I have conducted multiple stress test including prime95 and furmark at the same time for 6 hours and it works fine. I’ve completely changed ram as well as ran memtest86. I have completely reinstalled windows and it hasn’t fixed it. I am currently doing a scan on the hdd to check for bad sectors (I have had it for a while and maybe it’s just went bad?) I’m hoping it’s not the cpu or mobo.

Any help is greatly appreciated. I am completely out of ideas.

I'm with Cvet76 here, I think your PSU is at fault. Most local technicians will test your PSU for free or at least very cheap.

That power supply is a bloody napalm charge. I'm amazed it hasn't caught fire yet
