GPU not outputting video (Please help me)

Not open for further replies.
Hi, I am in desperate need of help at the moment, I am losing my mind as I try to upgrade my GPU. To begin, here are my specs:

Intel core i7 12700k
32 GB Corsair Vengeance DDR5 5600 RAM
ROG strix B760-I Gaming WIFI
Powercolor Radeon RX 7900 XT
Cooler Master V850 SFX Gold 850W 80+ Gold
Samsung 970 Evo Plus 500 GB M.2 NVME

So I have been gradually upgrading my system over the last couple months, and the GPU was the last one to replace (GTX 1080). The when installed, the 7900 XT's fans spin, but there is no output detected. I made sure to reseat the graphics card, as well as the PSU cables. I even did so again after it failed to output a second time. I wanted to make sure that it wasn't a complete dud so I tested the 7900 XT on another system (intel i7 8700k, ASUS Prime z370-A, 32gb corsair vengeance DDR4 3200, 750W 80+ gold) and the card output just fine, all it needed was the proper driver install. I then tried to boot with native graphics to see if I could attempt to install the RX 7900 XT drivers prior to seating it again just to see if it would do anything, but the AMD software Adrenalin thin wouldn't allow for driver install without an RX card present. I then tested my new system again with the gtx 1080 just to make sure that I didn't damage the PCIE slot during the transfer but the system worked just fine. My BIOS version is up to date btw.

I'm currently losing my mind over here, I don't understand what the issue could possibly be, besides an incompatibility with the motherboard and the GPU, but there's nothing on the internet that would suggest that. If anyone has any advice for me I would greatly appreciate it because while I could RMA, I don't believe that there is anything wrong with the card. Thank you in advance for any and all suggestions.

(PS, I also considered that 850W could be too low, but since the card worked just fine on the 750W system, I figured that it isnt the problem).
