RTX 4090 Power Connector Melting Issue: Still a Concern

Despite initial hopes, the power connector melting issue affecting some NVIDIA RTX 4090 graphics cards remains a persistent problem. NorthridgeFix, a graphics card repair specialist, has revealed that they continue to receive and repair RTX 4090 cards damaged by connector melting “every day.”

To underscore the severity of the issue, NorthridgeFix displayed a box filled with melted 16-pin connectors. The repair technician also attributed some of the RTX 4090 failures to melted CableMod 16-pin angled adapters, which CableMod had previously recalled due to 12VHPWR connector failures.

The ongoing connector melting issue with RTX 4090 cards is concerning, especially considering the hundreds of thousands of these cards sold over the past two years. However, it’s important to note that not all RTX 4090 cards are affected, and the problem primarily impacts those using the 12VHPWR connector, not the newer 12V-2×6 connector.

The timing of the connector melting issue can vary, with some reports indicating it occurs within months of installation, while others suggest it takes a year or more. The exact timeframe likely depends on usage patterns, with heavier usage potentially accelerating the issue.

On a positive note, NVIDIA has transitioned to the new 12V-2×6 power connector for newer RTX 4090 models and other RTX 40 series cards that utilize the 16-pin connection. The 12V-2×6 cable is reportedly more resistant to overheating, and there have been no reported cases of melting with RTX 4090 cards using this connector. Nevertheless, with many older RTX 4090 cards still in circulation, the issue of connector melting may not entirely disappear anytime soon.
