Help... Possible faulty 3080FE / PSU??

Hi Guys,

Not having much luck with tech of late! :(

I was very lucky to have got hold of a 3080FE in the last drop before Christmas but the last few days my system has become unstable.

This is intermittent but I'm getting screen blanking on my monitors along with driver crashes which is getting picked up in the Event Viewer. Now just this evening my system actually rebooted, the same screen blanking and this time I actually noticed that the lit Geforce RTX logo on the 3080 was also flashing at the same time like there was a power issue. Checked the event viewer and I had a Kernel-Power critical error message with event ID 41.

Now this Kernal-power error just denotes that the system shutdown unexpectedly and doesn't provide a cause. Seeing that the graphics drivers are crashing and that the card LED's also flashed and screen blanked before the crash the card seems to be involved in the issue somehow. I've also noticed that the LED that sits around the top fan comes on intermittently but its off more often than not.

To confuse matters one other thing I've noticed though over the last couple of days is that the power button is not responding well and can take a couple of presses to power the PC up.

My system was stable when my old GTX1070 was installed but its getting on now being close to 6 years old
and did have power button issues in the past but seemed to resolve itself as its been stable for many months.

Temps on my CPU and GPU are actually fine and I've been playing Cyberpunk 2077 and other games without any issues. I've run 3D Mark Time Spy a few times with no crashing issues either.

Do you think this is a straight up faulty card or possibly my PSU is on its way out and the 3080 is causing it it power problems. I should mention the PSU is an EVGA 750W Gold plus card but as said its getting on for 6 years old now.

I really hope the card is actually ok especially as it took months to get hold of the bloomin thing and its the PSU but seeing that 850w+ PSU's are also a rarity these days getting hold of one may be a problem!

If it is the 3080 again it may take a very long time before I can get a replacement so don't fancy going that route either.

Any insight or ideas would be appreciated?

It could be the PSU. But lets not jump to that conclusion yet, are you running any overclocks on any of your components?

Because I would start there first.

No overclocks no, although I did undervolt the 3080 but I was getting driver crashes and screen blanking before I did that and testing seemed to show it being stable. To confirm these issues have all been while idling, surfing the web etc not while doing any intensive GPU/CPU tasks.

Oh and just after I put my post up my system completely locked up and I noticed my RGB fans shifted to the standard rainbow pattern from the solid white I've got them set to. I'm replying now using my phone.

I’d rule out cables by reseating them.

Thanks, I will try that as I must admit when fitting the second GPU power lead in to the PSU it was a tight squeeze for my hand in the case when I plugged it in so might not have gone in 100%

Back in my system now and as it's behaving for the moment I ran a 3DMark Stress Test with the 20 loops and it passed ok so hoping that points to a healthy card??

I've gone ahead and purchased a new EVGA 850W PSU as I wanted one for my new build anyway so will just put it in and see if it makes a difference!
 
The second thing to ask is do you have two cables from the PSU running to the GPU, or just the one?

You should have two separate cables.

Just read above you're using two cables.

Hope the cables fix the problem mate. Glad you found a new high capacity PSU, that’s probably the next easiest potential fix and if it’s not the problem you can sell the old PSU.

Are you using custom PSU cables? I was and it caused very similar issues

No mate, using the supplied adapter in the box and my standard PSU cables.

The new PSU is arriving tomorrow but not sure when I'll have the time to install it as I work from home at the moment and need my PC.
Was playing CP 2077 last night and the game crashed twice from after around 2 hours of play, checke the event viewer and again there was a display driver crash recorded. Not sure if it is the same issue or just CP 2077 being buggy!
Will report back when the new PSU has been installed.

On a separate note I've decided to go ahead and start my new build as long as I can get the parts I need, just need a new case, CPU & motherboard and RAM and of course I already have the new PSU. Will re-use all the other components, CPU cooler, SSD's etc.
Going the AMD route this time, probably with a 5600x to start with but just don't know which motherboard to go with, really out of touch with that side of things but I'll post in the relevant section for ideas as this is not the place :)
