Might help a little bit, by heatsinking the contacts better, but the problem is the contact resistance, not the wire resistance. The connector itself dangerously heats up.
Or at least I think so? Was that a different 12VHPWR scandal?
- ryao 1y agoI thought that the contact resistance caused the unbalanced wires, which then overheat alongside the connector, giving the connector’s heat nowhere to go.

- bobmcnamara 1y agoContact resistance is a problem. Another problem is when the connector is angled, several of the pins may not make contact, shoving all the power through as few as one wire. A common bus would help this but the contact resistance in this case is still bad.
- ryao 1y agoA common bus that is not also overheating would cool the overheating contact(s).
- alright2565 1y agoIt would help, but my intuition is that the thin steel of the contact would not move the heat fast enough to make a significant difference. Only way to really know is to test it.
- chris11 1y agoI think it's both contact and wire resistance. It is technically possible to solder a new connector on. LTT did that in a video. https://www.youtube.com/watch?v=WzwrLLg1RR4 https://www.youtube.com/watch?v=WzwrLLg1RR4
- ryao 1y agoUneven abnormal contact resistance is what causes the wires to become unbalanced, and then the remaining ones whose contacts have low resistance have huge currents pushed through them, causing them to overheat due to wire resistance. I am not sure if it is possible to have perfect contact resistance in all systems.
