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

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


I have mine pc since 2021 march and never had single shutdown in games or when starting games.
But first time it happened 4 days ago, right after start Metro Exodus Enhanced Edition,in advertisement part before main menu. Monitor turns black,and pc shutted off. I saw fast flicker of case lights and pc turned off.
To start pc i presset power button and its ok. Happened first time that thing. Also monitor flickered too for a moment after 10 seconds after shutdown.

So after this i tested for many hours that games and shutdown not repeated:
1.Control
2.Metro Exodus Enhanced ( in game and main menu load )
3.Crysis 1.3 remastered
4.Quake 2 Rtx
5.Watch Dogs Legion
6.Cyberpunk 2077
7.3dmark all tests
8.Battlefield 5

Weird that it happened only once when launching Metro. Heh



ps:
Also
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.

 

How many devices are attached to the PS? That to me would indicate the PS isn't work as it's suppose to. MEtro is power hungry and if you 3090 isn't helping when the power draw starts. Remember not all PS are created equal. That name is not a brand name I know so that would be suspect to me. Contact the company or whom you bought and get it warranty for it. Too many PS shutdown can cause O/S issue and GPU issue as that will be the next hit from sudden shutdown happening far to often as it gets direct power from the PS anything happens to the PS will happen to the GPU as unintended consequence of this issue.

 

This is usually a WHEA error or some video driver watchdog failure.
Check windows event viewer for the time of the shutdown and see if any errors are logged, either at that time or at windows restart.

 

I would just keep tabs on the system for more events.

Not having to do a hard reset on the PSU would indicate it's performing as designed preventing dirty power from entering the system.

As mentioned though check event viewer for any logged events surrounding the power reset for potential causes. Windows .+ Drivers do funny things. I tracked down a power issue over the course of a month plus even swapping PSU's on a laptop to narrow things down.

If you're truly in doubt you can get a PSU meter that plugs into each lead and test the voltage to rule things out like cabling. Typically though desktop PSU's either work or don't, There's not much in-between with then since everything ties together in the housing. Seasonic is a OE supplier to other brands and has a good reputation when it comes to running long term. Most of them have a 10 year warranty and if anything is going to happen it usually does so in the first 90 days or so of break in.

If you do end up replacing it I would recommend going with a GOLD instead of wasting money on the Titanium. I switched to using EVGA PSU's a while back and they've been rock solid for years. In a pinch I did pick up a ThermalTake that was solid as well. The ratings are more for marketing as they only save you a couple of bucks on electricity per year and you won't save enough to make up for the price difference.

 

My pc shutted off and stays off ( not rebooted )i dont know if that was psu or brownout.
I just pressed power button to power pc. Dont switched ( power cycle ) that button on the back psu,no.No hard reset.

Also router plugged to wall dont disconnect even for second and laptop doesnt go to battery mode ( still was powered by other power cord ).

So that was propably psu or brownout ?


Happened just once i am using pc now few days and no shutdowns again.

So like you said techjunkie:" PSU would indicate it's performing as designed preventing dirty power from entering the system." ?

 

having dealt with rolling outages over days I've seen odd things when power is restored. Sometimes the PC comes back on its own and other times it required hitting the power button on the case. Seeing as though it's only happened 1 time it's hard to say what exactly cause it to power down. If everything is plugged into a surge protector it shouldn't be much of an issue though devices on the same power strip probably would lose power at the same time. During my experience though if the power tripped quick enough sometimes 1 or 2 devices would flicker and reset and other times everything would go down completely.

If you're really worried about it then hop on Amazon and order a backup PSU but, like I said before I wouldn't worry about it too much at this point.

 

But why router and laptop were not affected? Ah i remember that after pc shutted down monitor flickered after 10 seconds after shutdown. Why monitor flickered ?

 

The monitor probably went into power save mode after it lost signal from the PC.

Are the router and laptop plugged into the same outlet / power strip?

 

router plugged to the same wall socket like cord where is plugged pc. Laptop plugged to other wall socket and other power cord.


So propably there was power in house and maybe that psu one off?

 

Is this possible that was a brief power outage or brownout? I ask because 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. Also router plugged to wall dont turned off, because WIFI was active on laptop ,though.
Is this possible that only pc was affected due to brownout?Pc turns off only.
Or maybe not and psu issue?



Also when i cut power for 1 second by turning OFF/ON switch in power cord pc restarting,not shutting down.

 

I replaced my Seasonic 1200 due to power shutdowns. Installing a brand new EVGA 1300G+ PSU solved all of my problems!

No more power shutdowns!

I will say this too, Metro is extremely power hungry. It was the only title that would push my old 2080Ti beyond 500 watts. So, a 3090? Lol yeah. I haven’t played Metro on my 3090KP yet, but I imagine it would consume over 500-600 watts easily.


My [email protected] all cores, and my 3090KP HC heavily overclocked can use over 1,000 watts fairly easily. And I was getting power shutdowns.

No way that 850 Seasonic you have is enough..

I could get get by with a really good 1,000 watt PSU probably. Which is what I would recommend at the very minimum.


Even running games like Battlefield 2042 my system uses 850-900 watt in games.


Also, Seasonic has a super sensitive OCP protection. 850 watts is just not enough for a 10850K, and a RTX3090
