Pc instantly shutting down and rebooting during certain games

[slazy_rules]

so my pc is shutting down and instantly restarting as if someone pulled the power plug im almost 100% sure this isn't a heating issue, I've been reading all day trying to find a fix for this and literally can not find a single thing that points to a definite problem, the below screenshot shows both GPU and CPU temps with a game running so im almost sure it isn't a heating problem, im not sure what else could be causing this to happen i was playing overwatch earlier where it would instantly shut down but i fixed it by lowering all my graphics to minimum but lowering my graphics on the current game (The forest) isnt working at all, basically all i need to know is if i need a new power supply so i can buy one asap, so any help would be super super amazing! Cheers!

Your power supply is not something I would pair with a GTX 1080 Ti. You may need a new, better quality power supply.

what your describing is PSU failing how old is the PSU

Those symptoms correspond to BSOD with auto restart turned on.
PSU problem or overheating would cause shutdown (not restart).

What has to be done - turn of auto restart. Next time BSOD will give info about the problem, that caused it.

Already turned had it turned off with no succession.

Personal preference is SeaSonic FOCUS and EVGA G2/G3.

Would these be suitable for a Gtx 1080Ti? also would you go with 750w or 850w, cheers!

Yes, 550W and up of Tier 1 or Tier 2 is good enough for a GTX 1080 Ti system.

650W for single GTX 1080 Ti
850W for 2x 1080 Ti SLI

If 750W is not much more cost than 650W and you want it then go for it.

Also forgot to add the fact it only started happening a month or so after I added in the Gtx 1080 Ti and had never happened before at all

Probably a capacitor or something finally went bad. Parts degrade over time. That's the thing with cheap, low quality power supplies. They work, up until they don't.
