RTX 5090 Meltdown Investigation: Uneven Current Distribution Points to Design Flaw
2025-02-11
YouTuber Der8auer investigated a recent RTX 5090 graphics card meltdown. While many blamed the use of a third-party 16-pin power cable, Der8auer's tests revealed uneven current distribution in the 12VHPWR connector, even with official cables. One wire carried over 22A, exceeding safety limits and reaching temperatures over 150°C, causing the meltdown. This isn't isolated; it suggests a potential design flaw in Nvidia's 12VHPWR connector requiring further investigation and improvement.
