Honestly this doesn't prove anything. It needs more testing to prove it. Now replacing 3 8-pin(24 total) connectors with 1 12 pin connector with less surface area is bound to cause problems as it has shown many many times. I would have looked to a blade based power connector with thicker wires, but less of them. Maybe a 4 blade 10awg design for consumers with options for 6 and 8 blades in the server. That would probably allow for over 900w peak per pair based on my limited guessing.
I thought the issue was that there’s no way to manage the current, so cables would catch fire because all the power would pass through a single wire instead of spreading the load over multiple. I’m not an electrician though, that’s just what I remember from all the testing done in the 40xx cards
It is actually the connector that is over heating due to poor contact or lack of contact and an excess amount of the current going through 1 or 2 pins beyond what they are capable of carrying. You could send over all the current with 1 positive and 1 ground if it were thick enough , but that would be a thick, bulky wire. Car stereos use 12 volt and you used to find a lot of people putting 1000w+(peak) systems in their trunk. The 8pin connector has more surface area, but was designed and specced the wires and contacts for a lower wattage. It is hard to re-spec that all these years later with all power supplies out there safely.
