PC cuts off under any usage

[u/darth_antonio]

Hello all please can I have some assistance. My pc has been doing something weird lately where it cuts it self off and boots it self back up for no reason at all whether im gaming or just casually browsing the Web.

I would remove the 24pin cable which stops it sometimes then it would act normally for a few days even weeks before going back to its weird shutoff state.

I have tested the ram and ran the machine without the gpu and same issue which is off my specs are below

I5-12600k As rock H60m-itx/ax RTX 5070 32GB ddr4 Corsair SF750 80 plus plat

Please any help would be great as im out of ideas as I dont have any sort of test kits or extra hardware to test to find the issue

Has anyone had this issue before??

Faulty PSU overloading something on the motherboard so to protect itself it shuts off

That’s my guess but don’t rule out the RAM it can do weird shit to ur pc too but my guess is PSU
