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.
The cards aren’t affected* it’s the custom cables people are using.
I wonder why he didn’t do a temp test without the extensions and just Nvidias adapter? Those parts aren’t hot and haven’t caused any issues from any reports so far. It’s ALWAYS had a custom extra cable. Increasing the length of cables increases power draw, it’s the basics of electricity. So yeah… increaseing cable length, and adding extra connections will make it waste more power and draw more…… it’s not surprising it’s only happening with systems with the extra cable length and connections that cause loss.
Also, the headline is misleading, he’s blaming the cards, when the only piece that’s ever melted is custom non approved parts.

He isn’t using a custom cable though. He is using the Corsiar cable that came with his PSU.
