My pc:
10850K stock 4800mhz stock Kraken X73 good temps
2x16 GB DDR4 GSKILL 3000mhz XMP
Seasonic Tx-850 Ultra Titanium
Gigabyte Rtx 3090 Gaming OC

I wanna ask about something. So i plugged my pc in march 2021. All is fine. No pc shutdowns,reboots,pc stable. Had one power outage in june.
But 3 days ago, my pc suddenly shuts off during launching Metro Exodus Enhanced just after cinematic part.
I was wondering if that was my psu or very short for split second power outage?

I had laptop connected to other power cord but laptop doesnt go to battery mode in this moment ( i checked event logs ). Also router plugged to wall dont disconnect internet. And my question is. It was so short power outage for a brief second that only pc went off or it was my psu? Thank you.

But when pc shutdown i saw pc case bottom lights flickered for 1 second.Also monitor flickered for a moment ( flickered for 1 second,10 seconds after shutdown maybe ).

All working fine no shutdowns actually. I tested all games no issues now.
