On: Nvidia's RTX 5090 power connectors are melting

I think the problem with this is that chips can only use a relatively low voltage around 1-1.5 volts. So if you supply 48 volts to the card it still has to be stepped down and this means more components and heat dissipation on the card. We are basically arriving at the idea of graphic cards having their own integrated PSUs, but this doesn't fit well with the current physical design of computers.

I feel like it could work with an external power brick and the card exposing a dedicated external port.

For what purpose? That gives you similar cabling problems to internal connections, but now that cable is far less protected.

It would be a different connector and it moves some mass and heat outside of the case.

If you want a different connector then just use a different connector.

Moving 5% of the mass and 1% of the heat outside the case is a bad thing. One of the main purposes of the case is to be one big hunk of mass.

The cards supply 12 volts today, which is stepped down. There isn't a significant difference between 48 volts and 12 volts other than the amperage
