Aren't 12VHPWR cables like https://www.overclockers.co.uk/seasonic-pcie-5.0-12vhpwr-psu-power-cable-black-ca-08f-ss.html https://www.overclockers.co.uk/seasonic

Sure, there are problems with the connector. But 600W split over a 12-pin connector is 8.3A per wire, and a 16AWG / 1.5mm² wire should handle that no problem.

- zamadatix 2y agoYou're correct about 16AWG however "But 600W split over a 12-pin connector is 8.3A per wire" is only what _should_ ideally be occurring, not what Roman aka Der8auer _observed_ to occur. Even with his own 5090, cable, PSU, and test setup: > Roman witnessed a hotspot of almost 130 degrees Celsius, spiking to over 150 degrees Celsius after just four minutes. With the help of a current clamp, one 12V wire was carrying over 22 Amperes of current, equivalent to 264W of power.
