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.

Because Roman showed very clearly in the video the issue isn't the device or the user, it's inherit in the design. Pushing that much current through those small cables is a really bad idea. It's needed to make everything smaller, but it has way too many failure cases. Even a small imbalance can cascade into dumping all that energy in one little cable, causing the plastic to melt and burn.
