specs

w400 thermal tank

14900k intel

4x48 ddr5 ram

thermal tank 1650 watt

8 hard drives 7200rpm (lsi sas 3008 card)

My pc will shutoff instantly while playing cyberpunk. I have frame view pulled up while it happens there is no indication of it going over 65c. It has to be playing for around 2 hours for it to happen. Then once it does happen it will shutoff and once im back in the loading screen for cyberpunk it shuts off again. Any ideas?
