GPU will not display as in a PCIE slot despite removing and replacing it multiple times, resetting the BIOS, getting what I am pretty sure are correct drivers, and checking my PSU connections. I have no idea what to do.

Posted earlier tonight. My PC is able to start and run with visuals when plugged into the motherboard, but not only will the GPU ports not show anything, my BIOS does not recognize anything as plugged into the PCIE slot. I am running CachyOS and have gotten drivers, and still nothing has worked, and I am running out of patience.

What's the board model? Board BIOS up to date?

I have a GIGABYTE B850 Eagle WIFI6E, and I have not checked if the BIOS is up to date. There are no lights on the GPU I can see, and when I try starting with the GPU the VGA light comes on, but not when my DisplayPort is plugged into the motherboard.

I would try updating the BIOS. Your motherboard released about a month before your GPU, so, technically, it could be unsupported, although Idk if that's likely. Could be a dead slot or GPU, but it's worth trying everything before going that route.

I have updated the BIOS. When it was done restarting and updating, the GPU turned on, and the fans started moving, but the BIOS doesn't register it as in the PCIE slot.

Ok, have you tried exiting BIOS? Weird behavior from BIOS, but if it's posting and receiving power, it might just be an odd BIOS display issue? Idk what else that could be other than a faulty motherboard.

The PC functions when it's plugged into the motherboard but with the GPU it's still not working. I've reseated it as well, and reset the BIOS. But what would I need to look for on the pins of the GPU?
Cold-Sandwich-34@reddit
Anything that would indicate damage. How is it plugged in btw? A photo might help.

It's plugged in like this
The only way I could figure out posting a picture.
Cold-Sandwich-34@reddit
OH that's the problem. You are not giving it enough power. Both of those plugs need to be populated on the PSU. There's a reason they gave you an adapter.
XaghiTheDarkMistress@reddit (OP)
That worked! Thank you! I feel like an idiot but it's working now!
Cold-Sandwich-34@reddit
I'm glad! Yeah, the purpose of the 600W connector is to take the place of multiple PCIe cables. The adapter still needs both, you were under-powering it.

I hadn't realized. Thank you again, I'm gonna get some sleep, it's 6 am and I have a TTRPG session this evening lol

So, Newegg gave me a free liquid cooler as a gift with my case. I decided, to get more clearance on the top slot that was actually PCIE 5.0. and after doing that and reseated the GPU there. Now it won't turn on at all even after I reupdate my BIOS. I'm going to bed, hopefully I can find a solution some time tomorrow or this week.

The pins look fine. I believe that it may just be this PCIE slot. I've decided I'm gonna return the GPU I have and get something a little cheaper and smaller to make it easier to move it around to other slots.
XaghiTheDarkMistress@reddit (OP)
Okay so now it just won't boot my OS!
XaghiTheDarkMistress@reddit (OP)
OK so I disabled Secure Boot and was able to boot up my computer.
XaghiTheDarkMistress@reddit (OP)
I'll give that a shot soon

The VGA light usually can indicate some sort of general issue that the board has with the GPU(whether a detection issue or power issue).
Hopefully, can update the board BIOS for best up to date compatibility to rule that out.
Also, if the PSU came with a Nvidia power cable, using that cable instead of the adapter that came with the GPU(if the PSU came with this cable).

PSU model is MSI MAG A750GL PCIE5. I updated the BIOS, and the GPU does turn on now, but it doesn't register in the BIOS as in the slot.
