3080TI Founders Edition unexpected shutdown issue

JonnyGuru works for Corsair now that is why he was not doing the reviews on his/the old site for years now and now seems it is now gone.
 
It's interesting, my friend had this EXACT same problem with a similar spec system, weird shutdowns when gaming - for no apparent reason at all, tried everything, new PSU, reinstalled windows, perfect temps, ran with just bare basics no change... literally couldn't figure it out. In the end we re-seated the CPU and everything was fixed... ¯\_(ツ)_/¯ (been building PCs since 1997, so not new to weird issues, but this was a weird one)

I doubt it's the PSU - I run a 3090 with a mediocre 750W PSU and I've never had a single issue, ever (3d rendering as well as gaming). But it'd be good to rule it out with a different one.

Out of curiosity, have you tried running it with literally every other peripheral and hard disk disconnected (literally running it with the bare components) ?
 
Why would you even want to run a new high end GPU like a 3090 or such with a "mediocre 750W PSU" as it is the most important part of any PC?

Try running it on a Q-Tec. ;)
 
I also have a new 3080 Ti, they can pull 400W+ if the power limit is increased.
As everyone else says, its very likely its a power delivery issue, either insufficient PSU or fluctuations / droop caused by the load affecting other components. Unplug everything non-essential.
Ensure the GPU is fed from two separate rails and that the cables are securely plugged in. REMOVE any overclocks and undervolts, hell I'd even go as far as overvolting the RAM and CPU for the purposes of testing stability. Definitely run a monitoring / logging too like HWINFO64 while gaming so you can see what goes wrong at the time the power drops
 
Still confused by this 10GB 3080Ti but assume that's another typo.

As mentioned I would try to reduce the overall system power utilisation, unplug those HDDs for starters and make sure you've got dedicated power leads to the GPU.

Had the same issue with my 1600x It was due to the heat sync being tightened down too much. Caused the system to shut down randomly and require hard reset.

delta and seasonic have been around for a lot longer than super flower.

super flower has a rep for issues like the op's where it just cant deliver.
https://forums.overclockers.co.uk/threads/possible-super-flower-psu-issues.18769149/
plenty of threads like the above around the net.
again just my opinion others may think different.

Super Flower has been around for 30 years. Hardly a fly-by-night operation. The only thing they have a "rep" for is making some of the best power supply platforms around. At least amongst those who know what they're talking about. And are you seriously suggesting that the other top OEMs don't produce platforms with issues too?

https://linustechtips.com/topic/1093286-why-you-shouldnt-buy-a-seasonic-focus-plus-goldplatinum/

Plenty of threads like the above around the net.

So again, you're entitled to your opinion, but objective measurements say otherwise. Super Flower are, factually, a top tier OEM for PSUs regardless of your views.
 
Maybe its just me, but there seems to be very tribal following when it comes to PSUs compared to other PC components.
With people either swearing by a specific OEM (like Super Flower) or re-badger (like Corsair).

Seen it on various Tech discords too.
 
It's massively unlikely, that an average 850W PSU that's working correctly, is causing problems for a system with a 3080ti in it. Myself and 4 other close friends are running 750-850W PSUs with 3080 / 3090s and it's just fine. The only time the PSU might be to blame is if it's faulty, but then again - switch-mode power supplies don't really tend to go into degraded/faulty states, they just go BANG! and that's that.

The best thing I'd recommend, is to strip the system down completely, and literally run it with nothing at all connected, other than mouse/keyboard/monitor and a single SSD, then start from there. If it's still crashing, you can start to look at individual components, but until then - the only way to work out a problem like this, is to strip everything right down to the most basic possible state, then work from there.
 
Again it does not matter if its a good brand and brand new and 850w, it now on these new top AMD/Nvidia GPU's matters how it handles or does not handle Transient Spikes.

So "me and my buddies run 2x3090Ti's on a Q-Tec 550w and it is fine" is getting kind of old, best of luck when it blows and hopefully does not take the rest of your hardware with it.

This is just nonsense, and only encourages people to go out and spend stupid amounts of money on very high power PSUs they don't need. Literally any PSU you buy - such as the OP's 850W EVGA (which meets/exceeds the recommended requirements), will have no problem at all, absorbing transient spikes - they're literally all designed to handle sizable transient spikes.

The OP's problem may well be a PSU issue, but unless he can instantly rule it out by swapping it - I'd suggest he focuses on stripping the system down, then perhaps re-seating everything, before prematurely diagnosing the fault and spending money which won't fix the problem.

It's not nonsense, he is stating facts. Seasonic Focus Plus units (among others) had this issue and the 'fix' was to include inline smoothing on newer units. So it is a thing, have a read on the Internet and you'll find examples of it happening.

It's all a load of tosh.

Any half decent 850W power supply is fine for a normal build containing a 3080 / 3090, that's basically the end of it.

I'd say the multitude of videos, reviews and customer complaints would say you're wrong - The high current peak transient draw of the 3090 especially has been shown to cause some PSU's in some systems to fail so the claim of "Any decent 850w PSU..........." isn't 100% accurate.
