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.
Using custom cables even in that scenario would still lead to cables melting.
It’s from increasing the cable length and therefore the required power draw to draw the required amount to power the device. It already happens with 8pin systems as well, this isn’t unique to the delivery system either.
Using too many extension cords has the exact same affect… it’s like blaming the heater because the cords melted. But no, let’s not blame physics, let’s blame the GPU(heater) -.-
Now you’re really showing how uniformed you are. It’s not an extension cable, it’s 20cm in length total which is significantly shorter than what comes with standard 12Vhpwr native PSUs at 60-70cm.

Did you watch the video?
Sure they did…had their eyes crossed, fingers in ears yelling:
