RTX 5090 cards may have problem with uneven power distribution on 12VHWPR cables Roman “Der8auer” Hartung quickly reached out to the person who revealed the first melted RTX 5090 Founders Edition card this weekend. As it turns out, this person lives close to Roman, allowing them to have a long conversation about what happened. The […]
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 🤦
That’s…sooooooo Apple…FFS 🤦
