[SOLVED] Computer restarts randomly when playing games!

[benana]

When I play any kind of game, my computer randomly restarts during the gaming session. I have recently factory reset it so it's not a virus for sure.
Specs:
Intel i7-6800k @3.4GHz
16 GB RAM
GTX 1070ti
MSi Motherboard

My temperatures are fine. I'm not sure what PSU I have to be completely honest.. If the PSU is using too much would the PC do a little quick refresh?

Stability issues including hard reboots when under heavy load (like gaming) are often caused by an inadequate or failing psu. This is very serious, if a psu fails completely there is a chance it can damage other components. This is why we need make and model of psu to check the quality and suitability. However even the best psu’s can go faulty buts it is less likely.
