They would have been so much better off using a 2 wire power connection like they use for car subs than this. Just tighten down the wires.

Nv:"Oh we made a connector that can peak at 600w" Everyone: "what about any safety leeway?" Nv:"What's that? Oh, AI Didn't say we needed that"

    It's not really the wattage that's an issue.
    If it ran at 600 volts, it would only be 1 amp.

    But at 12v, it's 50 amps of current.
    Which is a lot.
    And it's not massively peaky/bursty, so it needs to withstand that constantly.
    Pretty sure something like 10-15mm² cross section of copper is needed for that, which is a thick cable.

    But, this is also a problem that has been solved elsewhere. For whatever reason, manufacturers have settled in a terrible solution.

    As I understand it, not "manufacturers," Nvidia specifically. They designed the connector then basically forced PSU makers to follow because they're 90% of the market.
