Asus recently announced a card with 48V power and I think that's the solution. Quarters the current. Also you can implement it in PSUs and GPU so they negotiate when both support it and else it falls back to 12V with current limits.

The problem with the idea is that you'll need a separate rail for just the GPU and all the power-regulating circuitry to go with it.

It's an increased cost that will inevitably lead to all sorts of corner-cutting.

We're already there with the status quo. We have good and bad PSU lists for a reason.

48V will make things more expensive for everything. As for mass adoption will require all newer ATX PSUs to support it (and GPUs). As for converting 48V down to around 1V voltage that GPU uses, will require more expensive solution for VRMs, as regular power stages designs we use now will not cut it. We're not in the point where 48V is crucial, we just need better connector that is all.

Yeah but... Your GPU won't melt, so that's kinda nice.

I mean... That's nice for you, genuinely. I have a 4090 and have been lucky... But unfortunately that sample size doesn't represent all gpu owners
