Computers New Build Trouble

Tonight I finally got my 18 year old to finish getting the parts for his PC build that has been in progress for some time now, and then when we added in the GPU and a pcie wifi adapter all the sudden the damn thing wont run post.

Before today with just the mobo, power supply, RAM, CPU and cooling system connected with an M2 SSD in place, we could do a test to make sure everything connected and we had all the RGB lights come on for the motherboard and fans were running. But once we added the two new components mentioned above, when we powered it on the RGB lights came on for a moment and then went out, and we didn't see if the fans spun up in that moment before it went dark.

Any suggestions on what to try next to see what went wrong and if anything is damaged? First thing I did was take back out the GPU and wifi adapter that we added and re-check all the other connections, but that didn't help.

Possible problem I saw was that for the two GPU power connections one of the cords was a PCIE with the 8 pins and one of them being a blank slot, but the other cord was marked CPU and had all 8 pins in place. The only other thing I could think of is the video cable that was connected was close enough to part of the slot rails that it could have been grounding to the case, but there was nothing that seemed like an audible short.
