I'm glad they actually made it one connector with different wattage.

And hopefully the 4 auxiliary pins will have some kind of sensing or communication to announce to graphics card how much watts they support, so GPU can decide to run something like "emergency 2D only mode" that would just inform user that power delivery is inadequate, vs running full speed if PSU/cable can offer enough juice. I mean, with 4 pins you don't even need chip in PSU, it's enough to just have active/inactive pins, so eg 100W is pin 1 active, rest disabled, up to 600W with all 4 active. There's enough combinations to cover 50W increments

Main thing is we can actually have 450W PSU with this connector, and lower end GOU all running fine, not just use it for 1kW+ PSUs

AWG Wire Gauge Chart For All 44 Wires (Ampacity Chart)

Picking exactly the right wire size is not an easy task at all. Different AWG (American Wire Gauge) wires have different diameters, cross-sections, and allow only a limited number of amps to flow through them. To adequately figure out what size AWG wire you need, you require at least a wire...

600W over 6 pairs is just over 8A per wire, so we're still talking #18.
