Pc randomly shutting off

[Joe_mac154]

I’m having a problem where my pc will randomly shut off normally during loading or when I’m walking into a large area in a game. I think the power supply might be tripping or something because I’ll be playing a game then all of the sudden my pc will just click then it’s off. I have to flip the switch on the power supply to off then back on for it to power up again almost like I’m resetting it. I have recently upgraded to a 3080 FE and a Ryzen 5900x but kept my 750w power supply. I’m thinking it could be that the power supply just can’t keep up when my components boost and draw a large amount of power quickly and just shuts down. It also happens in games I wouldn’t exactly call demanding like phasmophobia, but this could be a optimization issue that causes my card to draw a lot of power maybe? I don’t really know, any thoughts to help me out tho?
