You might want to check your power cables, some GPUs are melting because of it

The issue of melted power cables on Nvidia graphics cards doesn't seem to be over yet. Despite the introduction of the 12V-2×6 standard to replace the old 12VHPWR issue, a new report claims that some GeForce RTX 5090 units are still suffering from damage due to melted power connectors. The report claims the system used a 1000W Be Quiet Dark Power 13 PSU with original cables and properly installed.

This is not an isolated case

For your information, sources shared that their RTX 5090 Founders Edition unit failed during testing when the 12V-2×6 connector melted and damaged the cables and power supply. The same issue was also reported by one YouTuber who used a 4×8-pin to 12V-2×6 adapter on his RTX 5090. This adds to the list of RTX 50 series-related cases that occur even when users use the recommended cables and limit power consumption.

In theory, the 12V-2×6 standard was built to improve security through better connection detection. However, the RTX 5090's high power consumption, which can reach 500–600W, is believed to still cause issues such as uneven current distribution, excessive heat, and stress on the cables.

For now, Nvidia is still defending the use of the connector and stating that it complies with the ATX 3.1 specification. However, for users planning to buy an RTX 5090, checking the cabling and using a quality PSU seems to still be important for now.

You might want to invest in an original and SIRIM-certified power cable

Personally, we would advise you to get original and SIRIM-certified power cables. This is important for active PC users and content creators in Malaysia because their work, assignments and other important documents depend on a healthy power cable.
