Question Random System shutdown with no identifiable cause?

[Zdos123]

Hello,
Over the past 4 months i've been having an issue with my PC, it'll randomly restart (black screen immediately), sometimes just after i start a game, or sometimes just when i'm on reddit listening to tidal. At first i linked it to my keyboard as it wouldn't turn back on without me unplugging it (or at least i thought that), i replaced the keyboard and the issue is persisting and after further investigation it has no relation as to the keyboard being plugged in. When it restarts it takes a couple of seconds to reboot, sometimes it takes like a minute or two where it's completly dead to any input, power button, restart button both do nothing during this phase.

I've not changed anything recently, i can't really spot an indentifiable cause, it's a real pain in the arse though. Any ideas?

Specs:
CPU : Ryzen 5 5600x
GPU : Palit Geforce RTX 3060ti
Ram : 2 x 16gb 3200mhz Corsair (forget the name but the basic low-profile non rgb one)
PSU : Corsair TX650M
Storage : LG Laptop NVME 512gb, 3tb WD Blue 5200rpm, 1tb WD Blue 7200rpm
Thanks,

I remember a similar issue not to long ago. Turned out to be the power supply.

Least it's still very much under warranty
