Article is a summary of der8auer's video. Measurements show 22A/260 watts – nearly half of the card's power draw – going through a single wire heating it up to 150 °C in an open-air test bench.

I don't understand how the ATX standard hasn't adopted higher voltage rails for GPUs. Higher volts mean fewer amps which means less heat. 44A through an 8 pin connector is going to make a lot of heat. 11A at 48v would be much better.

Apple did something similar, then they put 48V pin next to 3V pin 🤦
