[SOLVED] PC Shutting Down

[Akau]

Recently I got a new PSU (Corsair CX750M) as my old one died, (EVGA 600+ Bronze). After this change, once I load into games of Fortnite I can play for around 1 - 3 minutes and then my pc powers off, and instantly boots back up.

Specs:
RTX 2060
i5 9600k
Corsair CX750M

If anyone knows a fix, that would be great.

First thing I would do is a CMOS clear. I do that any time I change any part.

Make sure to undo any overclocking that might be happening, including the gpu, during troubleshooting. (Boost is fine)
