First Report of Melted Connector on NVIDIA RTX 5090 Involves Third-Party Cable

A Reddit user reports damage to both the GPU and power supply, with initial findings pointing to potential issues with a third-party adapter rather than the GPU's design.

A Reddit user reported melted connectors on their NVIDIA GeForce RTX 5090 Founders Edition and power supply while using a third-party Moddiy 12VHPWR cable.
The incident occurred during gaming, with the GPU drawing between 500-520 watts, and resulted in damage to both the GPU and the power supply's power connector.
The user stated the cable was properly inserted and had been used previously without issues on an RTX 4090, but the thinner pins on the power supply side may have contributed to the problem.
NVIDIA had previously updated its connector design to the 12V-2x6 standard to address melting issues seen with earlier RTX 4090 GPUs, and the official adapter was not used in this case.
The user plans to file warranty claims with NVIDIA and ASUS but may face challenges due to the use of an unofficial third-party cable.
