New 7900 XT not detected

I was building a new machine and had the machine together using onboard graphics and the 7900 xt showed up today. I put it in the new build with the 2 8 pin power connectors. 

Result: Fans spin, but card is not detected in the PCI slot by the BIOS. 

Specs:

AMD Ryzen 9 7900X

CORSAIR HX1000i CP-9020214-NA 1000 W

GIGABYTE X670E AORUS MASTER

Troubleshooting:

- Reseated everything

- Tried a different PCI-E slot

- Took GPU from old machine and put in new machine (works)

-Took 7900 and put in old machine (Same problem)

Everything looks and feels like, to me, it doesn't get power. Any ideas would be appreciated.

You ever get a response or figure it out? (same issue as yours)

I sent it back as a dud.

You can try to update the BIOS, X670E AORUS MASTER F8c BIOS mentions "Improve memory & PCIe device compatibility".

Sending mine back (DOA) as soon as AMD's Warranty / RMA link is back up and running.
