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

[sew333]

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 after cinematic when is press E button part 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.

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

ps:So I am a bit confused. Everyone is saying that it is likely the psu with a problem...but they are also saying if it was the PSU’s over current protection, then I would HAVE to switch the flip in the back. I don’t have to flip switch.

happened once in 7 months of use.Also after shutdown I don’t have to flip switch on the back of psu.

Happened to me to without any flipping of a switch. Changed PSU and problem solved. 

So likely your PSU.

Try undervolting your RTX 3090...

Try keeping an eye on your temps. I had an odd shutdown or two before Xmas. Turned out to be my AIO building up a blockage and failing.

It would work and then not work, I was lucky enough to be monitoring it at the time. However this was alongside odd performance behaviour. 

Are you also able to monitor the 3090's memory temps they are known to get toastie. Never heard of it causing a random shut down though.

Saying all that this does sound like something in the power tripping. I thought that would cause a restart, not shutdown though.

[BitMaster]

I doubt the PSU was the reason the PC shut off.

As others said, monitor your temps across all chips, load test the system and see what happens.

The PSU has enough wattage to run your rig at full load for many many hours...unless it's faulty.

[sew333]

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.

 

Is any difference between short power outage and turning off/on power in power cord? THanks

If that was momentary power outage why pc shutted down and not rebooted? Instead of fliping switch OFF/ON in power cord when pc shutting down and rebooting.

 

Thats why i asked. If that was momentary power outage why pc shutted down and not rebooted? Instead of fliping switch OFF/ON in power cord when pc shutting down and rebooting.

So propably psu? If router dont turned off and laptop dont go to battery mode <in this moment>

With a normal Bios you are always able to configure what the PC does AFTER a power outage:

1. Power ON

2. Stay OFF

3. Return to previous state ( state that it was in before the outage, either ON or OFF )

 

When you cycle the rocker I/O switch it will actually fall under the same rule listed above, there should be no difference.

That leads me to the assumption that you encountered a hardware failure state ( not broken hardware ! ) that abruptly lead to an emergency system shut down.

That can happen and the system will usually stay OFF after this sudden shutdown. There are also usually no log entries anywhere because Windows OS got killed without any warning.

It can have many reasons, a rare Bitflip or a more common memory corruption, firmware error states due to various reasons, many many possible reasons.

If it only happened once and never again since, stay calm and don't mess up a system that is not broken. Such things do happen to every computer.

Run some stress tests with common sense, let it ON for 48-96h at least to see if it can handle 5 days without a reboot ( it should easily ). If it does all that there is nothing to worry about.

Thank you for answer. But i wanna ask why monitor flicker after 10 seconds after shutdown? thats weird

 

Is  this possible that was brownout but router and laptop was on power?

Could very well have been a powerine issue and maybe your Router's AC-Adapter can bridge a longer timespan than your PSU could.

Don't think too much when it's a one-time thing. Likely you will never find it out unless it happens again and/or more people have the same issue(s).

 

Overthinking leads to repairing an otherwise great system to death.

[sew333]

oki thank you so much Bitmaster

Hi Sew333,

If your monitor was constantly flickering for ages after I would work out what that is. If its just a short flicker 10 seconds after a shutdown, that is probably just a small signal left over as you shut down. I cant be sure without physically seeing the system. My best guess dont worry about it.

As for your main problem, again if this has only happened once. I would not worry about it too much. If that happened to me I would have already just kept a mental note for future reference. That would have to happen a few times in a row within a week for me to go digging around searching for a problem. Its easy to worry when its your own system. Really though some time has past now, you probably will never know for sure. It really could just have been a random one off.

If you really are worried, there are two things to try. Go through your system and carefully check your power connections. Check they are properly connected and for things like excess dust etc. Check them for tension, has one got pinched by the back panel of the case etc. Its easily done. 

Secondly if they are cheap in your country get a watt meter for the plug, check the system is using the power it is suppose to, helps to problem solve,,, sometimes. 

Finally keep an eye on your temps, things like all the GPU temps, hotspot and memory. Dont stress about it too much just keep an eye.

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

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 ).

Why monitor flickered after 10 seconds ?

Ok, I hear what your saying. However ask yourself. Were you looking at the laptop, router and PC all at the same time when this happened?

A split second interruption in the main power of your home would be all it would take to shut your PC down, especially if it was loading a game at the time. Your laptop and router probably just didn't show the problem.

You either had a split second drop in mains power. Or, you have a strange short in your PC. Or a growing temp problem your not noticing yet.

If it's all working fine now, my bet is it was a split second power cut/drop out. It fits everything your describing to be honest.

[sew333]

Oki last question. If that was split second power cut/drop out why then pc not rebooted? I simulated that one time,by switch power button in power cord,OFF/ON fast and pc rebooting ,not shutting off. THanks.Sorry for my english.

Sew333, I honestly don't know. It's a guess but you said the computer was under load while it was loading Metro Exodus.

I have not done any extreme over clocking in years. When I did I had shut downs without a restart caused by instability. A split second power outage could have caused similar. I cannot say for 100% though mate. 

If it's working now I would just keep an eye on it. If your still ok in a couple of weeks. Seriously mate, just forget about it. I would if it was mine.

Someone said:"
I have to express my frustration with the exact same power supply and nearly identical setup except I have an RX6800 and a Z590 board. A simple setup with no overclocking and Intel power limits enforced (not using Asus settings). I built this PC around Apr 2021 with all new components, got done, and it wouldn't post. After testing everything, it turned out to be the TX-850. I've been building PC's over 35 years and hadn't seen a no post in almost 10 years! Decided put the TX-850 back in because I couldn't believe I had a bad Seasonic and it posted!

Got windows and everything setup and after about 2 weeks the power supply clicked and shut off doing nothing more than web browsing. The ONLY way to get it working again was to flip the switch, pull the cord and let it discharge a few seconds (mobo lights off). After that, the computer would run normally for a random amount of time from days to weeks then I'd have to repeat this exercise.

THIS WENT ON FOR ~6 MONTHS (didn't have time to deal with it), completely random and usually NOT while gaming. I threw in the towel and got Microcenter to exchange my PS for the same one. Put the new one in and it POSTED right off and has been fine for 2 months now - until yesterday. I was gaming last night and it happened again - click, shut off. There is NOTHING in event logs, it happens too quickly for windows to log $^%#. IMO, there is some odd issue with these power supplies. A google search led me here!



I'm about to toss this over-priced POS Seasonic in the bin. I cringed spending almost $300 on PS but I wanted the best. I've used many of their supplies in the past and they have been excellent. That's why I stuck with them for my latest build. However, seeing all the strange issues with a simple search makes be believe they have missed the mark on their new supplies. There is a faulty component somewhere in the design.

So rma my psu?

A shame that you do not have a spare PSU and send this to Gamers Nexus for testing.

 

 

[Bossco82]

Hi Sew333,

If its playing on your mind that much and the PSU is still under warranty then open a RMA ticket with Seasonic. If it helps I run a Corsair TX850m PSU and it has had no problems powering my system. Its quiet too.

[sew333]

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.

So only pc affected.

[AngleOff66]

Just saw a LTT video about a pc shutting down.  The first few mins are Linus, the rest is all Anthony.  I did not know about event viewer in windows. 

Maybe take a look?

Best of luck

It was so short power outage for a brief second that only pc went off or it was my psu?Laptop and router dont notice anything.

[sew333]

Ok thanks all for help. Issue not repeated still, so its ok.But still dont know why it happened heh
