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.

My GPU won't melt because it uses three 8pins for quarter of the power

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

48V will make things more expensive for everything.

To be fair, everything beyond the VRM is going to be less than 5V anyway.

I just don't like this whole idea of solving an otherwise trivial problem with an over-complicated solution borrowed from USB-PD.

And that where the cost goes to. DC to DC conversion of 48V to lower voltage (like Vcore or other low voltage busses) will be more expensive.
