Without taking away from how cool that is, the Threadripper 7980X manages to run at just 3.4W/core according to GamersNexus [1]

It's pretty amazing where everyone (other than Intel) is on the perf/W scale.

I don’t know but I’m curious: I’d imagine at that many cores you’re probably reaching the limits of how much power the socket can realistically get? I know some motherboards have that supplemental power port.

Yeah motherboards for threadripler have extra power supply connections.

I believe there's a the option to connect two

As I understand it, the main issue is cooling the damn thing. Socket SP5 can do up to 700W, and that's all emitted from a heatspreader 72mm x 75mm.

Getting the power into it isn't trivial, but it's not rocket science either. When the socket has 6000 pins, you can spare a few hundred for power.
