I just made a new pc and swapped the 2080 ti from my old case to my new one. It was working great until all of the sudden it crashed after hours and the 2080 ti had one red light above where you plug in the power cables. It wouldn't display so I took it out and put it back in and things were back to normal with the red light gone. It's been about a day now and I was playing some games and went to watch tv and when I came back it has the red light again but is working. Does anyone know what this red light means?

Are you using one PCIe Power Cable to your Graphics Card or Two Separate PCIe Cables?
Two Separate PCIe Power Cables are recommended.

Just one I believe. 8 pin to the power supply and the other end has two 6+2 pins plugged into the graphics card.

Add a Second PCIe Power Cable.
Use only  One 6+2 pins from each cable.

Thank you. You think it just wasn't getting enough power?

I'm using the corsair RM1000X. Sounds like an easy fix. I will open it up and run another cable through tomorrow afternoon. Thanks for the help. I was getting a bit scared xD

Not sure what a single red light means, but 3 red lights mean the card is stuck in flash mode.

Keep us posted.

I added another PCIe and my computer has been great so far. Thank you for the help I really appreciate it! I'll post if it happens again but I think you solved it. Thank you again.

2080 Super ftw3 - red light on
no red light previously; had to remove card to make nvme change, put it back together and now I have a red light...
no changes, 6 pin cable inner plug, 6+2 cable outer plug, EVGA 650W Platinum power and cables
thoughts?

Resolved - had a loose power cable on the PSU end. Check all your connections once.
