Is my Seasonic Tx-850W going bad? Shutdown once

[SLitw]

Hi my pc: 10850K stock 4800mhz

2x16 GB DDR4 GSKILL 3000mhz XMP

Seasonic Tx-850 Ultra Titanium

Gigabyte Rtx 3090 Gaming ( 2x8pin,2 separate pcie cables )

Asus Z490 Maximus

1 TB SSD


4 days ago…i launched Metro Exodus and during advertisement part,my pc just shutdown. I rebooted again and its fine again.

Happened after launching game on intro advertisements part.

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

I remember that when pc goes off ,pc case lights flickered for a second and then turned off completely. That flicker not happens when i shutting down pc manually.
I have checked to ON in bios: Automatic restart after power loss.

Also monitor flickered 10 seconds after shutdown.


In my room i had laptop on connected to other power cord in this moment, and in eventlogs there was not log about power mode changing to battery.So i think power was on in house. Also router plugged to wall dont turned off, because WIFI was active on laptop ,though.



Ok 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

It's not overcurrent protection getting triggered.
That causes complete shutdown of PSU needing power cycling to clear it.
I don’t have to flip switch.

Hhmmm... Sounds more like you had a THERMTRIP event (processor got too hot). Run a tool to monitor the processor temperatures and see how hot the processor is getting during normal operations and gaming.

Hope this helps,

But it happened right after i click launched game. No temps issue. Also after this i run few games for many hours and no shutdown.

Seriously? How do you know? Run a tool and find out.
