I was kinda thinking in this general direction yesterday. My PC is a bit older, so it doesn't draw 1000W like a proper gaming rig. I doubt I can make it draw 400W, but it has a proper THICK boy cable to the wall socket for those 400W, but we expect some thin, probably braided, cables to do 600W for a GPU? And why 12 pins, if all you're giving the GPU is the same 12v in all of them?
Fucking redesign PSUs from the ground up already, fewer pins for GPU, but have them massive, cause at this point the GPU is the main power user in your build.

Tell that to the 4090 connectors that have started to melt.
Sure, theoretically you could push the wires to be even thinner. The connectors are the actual weak link. But thin wires means small flimsy connectors. And we're already seeing what just 450w can do right now to the new connector spec.

I don't really see the point of higher voltage cards. It's not like you're actually pushing in 12v to the chip. You'd just be forced into having more voltage stepdown circuity on the card.
Only thing it would help you at is pushing the same wattage but with fewer amps, and maybe that's more efficient or something, but I'm not enough of an electrical engineer to know.
@roboneko @alyx @LukeAlmighty
to add to your answer:
Watts = Volts x Amps
Cable thickness is directly proportional to amps.
With the same wattage, more volts => less amps => thinner cable.
@alyx @LukeAlmighty the meltong connectors were on the cable side, not GPU side, and only certain PSU manufacturers had this issue AFAIU. But yeah it is near the limit...
