2080Ti SFF Build: PSU Causing Crashes?

[LyondellBasell]

Hi! I've been troubleshooting a new SFF build for consistent crashes and I'd like some advice.

Build is 9700k/2080Ti FE on Silverstone's SX800-LTI. No overclocks.

 

Metro Exodus, Obduction, PUBG, 3dMark Time Spy, and Firestrike crash to the desktop (no BSOD or shutdown) at some point during normal operation. No error message is returned, just that the game has crashed, or the benchmarks did not complete.

Lowering the graphics quality in games seems to prolong the length of time they will run but does not stop the eventual crash.

 

I hooked the 2080Ti up to a second, separate power supply and the crashes to the desktop stopped immediately.

 

Is this a bad card or a bad PSU? I'm not getting any error messages at BOOT like "overcurrent protection tripped" or anything of the sort.

Does the 2080Ti require more than an 800W PSU?

Does anyone else have a 2080Ti in their SFF build? Can you recommend a good PSU?

 

Thanks for your time

Overcurrent will be PSU. Not sure what's causing it though. 800W is more than enough for a 2080 ti.

Your rig probably isn't using more than like 500 watts at load, and that's probably a high estimate there.

My best guess is a driver issue, maybe? I'd think that the power supply would cause a hard crash to the system rather than a crash to desktop.

Try downclocking (underclocking) the memory by 100MHz or more. There was a bad batch of Turing cards that went out that were causing issues, and supposedly it was determined to be faulty memory as the culprit.

Daisy chain or two separate cables? A daisy chain for something as power hungry as a 2080 ti might be an issue on this particular PSU

Is this a fresh windows install?

I went with two separate cables straight from the PSU

Yes. Installed from the latest ISO onto new drive.

That was my initial thought too, but after a total format, Windows reinstall, and driver reinstall, AND a driver update to the 425.31 on the 11th, the issue reproduces the same.

I have the exact same issue with my 2080ti black edition. I am on a second PSU has well. Went from Silverstone sx700w gold to sx800w LTI. Did all the same attempts to solve the problem. . My temps seem good. I am coming close to RMA, but it seems this is an unaddressed issue with the 2080 and 2080ti. I am wondering if there are spots on the VRM that are not in contact with cooler, but I don't want to void warranty to find out. The only solution I found is not running any overclock and restricting the fps in games to display based. Plus under powering the GPU 90%. But that keeps clock speeds down around 1575mhz and cant even touch the memory clocks on the gpu.
