Don't those Ada 6000 GPUs support NVLink? I think I can even see the cover for the connectors in OP's pic.

edit: Hm, finding mixed information online on whether that's still supported or not. Apparently it was removed in workstation GPUs.

Nope, they don't support it. And afair even if they did, you would be limited to connecting only in pairs, not all 6 together

Honestly, I made the same mistake when I added a GPU to my (not $48K) existing homelab. I got a Ada 4000 for its slim form factor and low wattage, but realize after I bought it that it does not support NVLink, so I can't really effectively double it up later if I wanted to. Live and learn. I suppose you might research that a little before blowing that much money though LOL :)
