Finished a build from scratch last night and cannot get it to post, can’t even get a display. First off, build specs (essentially the Obtanium Reference System with a GPU difference):

PROCESSOR (CPU) - Intel Xeon W5-2565X

MOTHERBOARD - Gigabyte MW83-RP0

GRAPHICS CARD (GPU) - GeForce RTX 5070 Ti

PRIMARY STORAGE (SSD) - Samsung 990 PRO 1TB M.2

SECONDARY STORAGE (SSD) - Samsung 970 Evo Plus 2TB M.2

MEMORY (RAM) - Corsair 64GB WS DDR5 5600MTs (4x 16GB sticks)

CAPTURE CARDS - 2x Blackmagic Decklink Quad 2

CPU COOLER - Silverstone XE360-4677 AIO
360mm Radiator with 3x 120mm Fans

POWER SUPPLY (PSU) - Seasonic Focus GX-1000 V4 1000W

CASE - SilverStone SST-RM44 Server Case

Things I have tried so far: swapped the 5070 Ti with an old 1050 Ti, HDMI gives me no display with either.

Removed the Decklinks in case they were causing some interference, will reseat later once I’m past installing Windows.

I tried VGA direct from the motherboard, still no dice. With and without a GPU seated.

Reduced memory modules from 4x16GB memory sticks to 2x16GB and 1x16GB stick, no difference.

Tried booting with the BIO_RCVR (BIOS Recovery) jumper in either Default and On positions, tried BIOS_PWD jumper (BIOS Password Reset) swapped as well.

I double checked that the CPU pins were good and I don't see any issues.

As far as I can tell, no bent pins on the board. So I’m just completely up against the wall at this point. Any thoughts?
