Pc crashes during games

[Spacepotato2k]

When I play certain games my pc decides to crash, like it was just unplugged, then turns back on. I can play League of Legends and Counter Strike GO, but not Rust and Overwatch. My cpu and gpu temps are 40c and 70c, I dont believe its an overheating issue. Please some help, much appreciated <3

Specs:

MSI z97 gaming 5

Intel i7 4790k

Cooler Master hyper 212

EVGA geforce gtx 1070

Corsair vengence 2x4gb ddr3 2400mhz (Running at 1600mhz)

EVGA supernova 750G
