I have a 8700K (not overclocked), and an 2080TI (not overclocked), 7 USB 2.0 devices, 32gb 3000mhz ram, 2 x 140mm fans, 3 x 120mm fans, a D5 Pump, and a 650W Seasonic Focus Plus PSU.
While playing a game, after a little while sometimes 15min, sometimes 1 hour, and sometimes as little as 1 min, the computer just instantly shuts off, like some one just flicked the power off at the wall.
I have monitor CPU and GPU temps they seem fine.
Does anyone have any idea what might be causing this?
