Question Pc goes off

[litwicki23]

Hi 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
Aorus Z490 Pro Gaming
1 TB SSD

I bought machine and plugged in march 2021. No single issue,no reboots,no shutdowns. I played all games for many hours,no issues. Today...........i launched Metro Exodus and after cinematic part pc just shutdown<goes off>. I rebooted again and its fine again.Happened when gpu load change from 0% to 99%.



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

I go to neighbourhood and ask about power ,but they had power in this time. So propably not power outage for 1 sec?

I remember that when pc goes off ,case lights flickered once and monitor flickered. That not happens when i shutting down manually.


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

It's the PSU. Prime 850w and 1000w trips with RTX 3090. Cut the sensewire from the 24p ATX or buy a new PSU. 850w Corsair RMx/HX Platinum, XPG Core Reactor, Thermaltake GF1, Super Flower Leadex III Gold, that kind of stuff.

But this is TX model

All 850 and 1000w (GX, PX, TX) Prime have issues with RTX 3090.
