Computer power supplies have (usually) multiple rails, which are multiple voltage regulator circuits outputting the same voltage. You wouldn't be able to do that with two wires. Also, I think the connector needs to be larger to distribute load, and the ATX style pin connectors are already used and no one wants to add a completely new connector type on their assembly line.
- formerly_proven 4y agoModern ATX PSUs are all single-rail, including the highest power ones. E.g. Seasonic Prime 1600 W produces over 130 A on its singular 12V rail.
- Karliss 4y agoThe current connector 12VHPWR connector already joins all the wires together on GPU end of connector. So multiple PSU power rails isn't an argument why they couldn't have used two beefier wires and connector.
