> The RTX 50 series are the second generation of NVIDIA cards to use the 12VHPWR connector.

This is wrong. The 50 series uses 12V-2x6, not 12VHPWR. The 30 series was the first to use 12VHPR. The 40 series was the second to use 12VHPWR and first to use 12V-2x6. The 50 series was the second to use 12V-2x6. The female connectors are what changed in 12V-2x6. The male connectors are identical between 12V-2x6 and 12VHPWR.
