Power Issue with PC

[ConfiXs]

In the past day or 2 my pc shuts off 10-15 minutes after booting up battletech. Ive had this issue before with Snowrunner but it just stopped doing it out of nowhere so I really dont know what fixed it. Ive moved my VGA cables to different ports on my PSU, ran in different window modes, put my power option to the recommended settings, even switched the plug my power cable goes into. My gpu drivers and windows are up to date.

Sorry if I missed it in the post but what are your temperatures of your CPU / GPU while gaming ?

 

Switching off is a sign of overheating or PSU failure.

i also switched my PSU's fan mode from eco to performance and havent had a shutoff since, i really need a new case cause my current case chokes the PSU in a tight shroud

And it's back to doing it every 10 minutes
