Week ago i launched Metro Exodus and during cinematic advertisement part ( 30 fps ), pc just shutdown. I pressed only power button, rebooted again and its fine again. Happened once and i cant reproduce.

My question is. It was psu issue or maybe other hardware?

Power was in house,laptop and router dont notice anything.

i am running now game and no shutdowns. Happened once 4 days ago. Also i have pc until march 2021 and thats like today never happened.

Is psu going just bad,rma or what you recommend for me. Thank you


I think it was not overcurrent protection getting triggered or yes?

That causes complete shutdown of PSU needing power cycling to clear it.

I don’t have to flip switch.

Last question. So my shutdown was not related to OCP protection? It happened when i launch Metro Exodus in advertisement part ( 30 fps ).Happened once and i cant reproduce. Also I don’t have to flip switch on the back psu. Just pressed power button in case to boot pc.

If i run without issues that apps: 3dmark fire strike, port royal, wild life, time spy, Unigine Heaven
Quake 2 Rtx, Battlefield 5 , Watch Dogs Legion, Cyberpunk 2077,Ghost Recond Wildlands, Crysis 3 remastered, Crysis 1 Remastered, Metro Exodus Enhanced, Cod Vanguard, Control <-- 24 hours without shutdown. Its fine?

So issue with shutdown not repeated all working fine. BUt i wanna ask. Is any chance that this shutdown was caused just in a bug from game or driver issue ?? Thanks
