Nvidia RTX 5090 Faces Power Connector Melting Issues

Reports highlight overheating and uneven power distribution in RTX 5090 GPUs, with third-party and official cables both implicated.

Multiple reports have emerged of Nvidia RTX 5090 GPUs experiencing melted power connectors, with temperatures reaching over 150°C in some cases.
Investigations suggest uneven current distribution across the 12V-2x6 connector pins, with some wires carrying significantly more load than others.
Third-party cables, including those from Moddiy, have been implicated in some incidents, though testing also revealed issues with official cables.
System integrators and manufacturers have implemented measures like safety lights and colored pins to ensure proper cable seating, but the root cause may lie in the GPU's power draw and design.
Experts have called for design changes, such as using dual connectors, to better manage the high power demands of the RTX 5090.
