Hi my pc:
10850K stock 4800mhz stock
2x16 GB DDR4 GSKILL 3200mhz XMP
Seasonic Tx-850 Ultra Titanium
Gigabyte Rtx 3090 Gaming stock
Aorus Z490 Pro Gaming
1 TB SSD


I have my pc till April 2021. All was fine. All apps and games working without shutting off system. My pc is 24hours on in idling Windows 10 desktop. Today just suddenly pc powers off.
Pc was in desktop Windows 10. In some moment i heard CLICK from pc case and pc goes off.
I rebooted and its fine again. I checked power in house,and power was on.
My question. Is my pc failing? Why it shutted down? Or maybe it was voltage spike in house and pc only react?

As said above, shut down once or twice is no cause for alarm. It could have been a power brown out or something like that since the PC wasn't uder heavy load so it's unlikely it was PSU over-voltage or over-current protections that shut it down. Click is probably the relay in the PSU. Some PSUs do this 'click' once when they turn on and once when they turn off.

It can't be temperature related unless temps rise slowly at idle and reach a point where CPU would shut down system. That's unlikely too because that would mean a near total failure of the cooling and you'd notice that daily when you use the PC for gaming or anything.

I too say there's no need to worry. If you want however, you can use OCCT to stress test the CPU, GPU and PSU...

I doubt it would result in crash or shot down as you say system is stable under loads like gaming. A PSU that can handle power spikes of a 3090 should be in good working condition.

Not necessarily. It depends on BIOS settings. If it is set to do so by user or if it is like that in the BIOS by default it will.

If you've configured your PC BIOS to turn on when there's a power loss/cut, when you don't shut down the system from wihtin an OS or when power is suddenly cut due to a black out or something similar it would turn back one when the AC mains resumes.

It's a BIOS power setting which is under settings named 'advanced settings' or 'APM' or something similar.

Yes, if you have set it to ON it should turn back on when AC is back.

Again, if like you said system is OK under load and when it runs games I don't think you need to worry about it. As I said you can stress test it and see how it behaves if you like.

Can't say for sure. If some power issue (AC mains) caused the protection in PSU trip somehow maybe that's why it didn't turn back on and needed user (you) to start it back up.

Did you have to flip the PSU switch? Or you just pressed chassis power button, like always, and it turned back on?

Again you don't need to worry about this if it happened once or twice. If PSU had any trouble in power delivery it would show when running games with a 3090 I think.

How come nobody mentions the Seasonic Tx-850 Ultra Titanium + RTX3090 combination? Some members here would have a field day talking about how crappy Seasonic PSUs are... and how Corsair RTX would have been much better choice. I don't see them as often these days.

If you're going to make such an accusation it better be backed with some facts. Seasonic is highly rated by many sites. Yes they have had some mis-steps in the past couple of years, but the TX-850 is highly rated by this site and all the other major review sites. I'll take Aris' word over some hyperbole about them being poor.

It seems to be the edgy thing to do to trash on Seasonic because.... reasons?

Corsair RTX? Doesn't exist. Corsair RMx are you thinking of? Thats made by CWT..... Or are you saying Corsair TX? Because thats made by.... surprise! Seasonic!

Now to get into the nitty gritty that particular PSU had an issue involving OCP triggering while using RTX 3090 GPUs. Clearly though if it shut off at the desktop OCP isn't the cause here. But some are reporting such behavior anyway. This was heavily discussed here, in fact you were in that particular thread. This can be resolved by bumping up to a TX-1000. Doesn't make Seasonic bad, its a known issue, that affects more than just the TX-850.

I was just pointing out how some people here overreacted to flaws in Seasonic products and took the opportunity to promote Corsair products, whatever their motivation was. (you can search with some keywords you will know what I am talking about.)
I personally use Seasonic Focus GM850 with zero issues with RTX3080

I know what you're talking about, So it was sarcasm, got it. That user won't be participating in this thread. However sarcastic replies aren't helpful so lets not do that.

So can i buy Seasonic PX-1300W good idea?

1300w is overkill a TX-1000 would do the job, but either way thats a fix. That said you may be fine continuing with the PSU you have. This is a known issue with the RTX 3090 and the TX-850.

As RL said it, is a known issue with that PSU and graphics card (usualyl under heavy load when high current is running to the card and transient spikes happen) but since you said it happened in desktop which basically means system is under no heavy load and it happened once/twice I didn't think it'd be the OCP protection of the PSU doing this. Apparently, it can happen then too.

If the shutdowns keep happening you can change to the TX-1000 or some other god quality 850W or 1KW PSU.
