Why can't we just use more robust connectors (xt60 for example)? Or higher voltages? Trying to send low voltage, high current through a bunch of tiny connectors and hoping none of them melt seems silly. Is it just because no one wants to challenge the standard?
Better connectors cost more money, as do DC transformers.
Changing either one requires industry consensus.
3x pcie connectors (3x 150w) + 75w from the x16 rail gets you to 525w. Scrape together 50 more and that’s a 5090s max advertised power draw.
