Question whole pc turns off while playing Rainbow six siege

[joshuablofield123]

When mid game of Rainbow six siege my pc will turn off completely with no warning no bluescreen or anything.
specs: gtx 1070ti i7 8700k 16gb of ram

i checked temps while in game my cpu at hottest hit 82c and my gpu hit at hottest 67c, this is the only game it crashes on but before it was never like this.

In BIOS there might be some setting to turn off PC once the 82 or 85 deg temp reached

any way to change that?

What's the exact power supply? An 8700k won't shut down until higher temperatures than this.
