Despite attempts to address the melting issue plaguing the 12-pin power connector, design flaws continue to pose a significant challenge.
A recent incident reported by a Reddit user highlighted concerns with MSI’s 12V-2×6 connector, which is designed with dual-color tips to ensure proper insertion. Unfortunately, even this supposedly improved design suffered from the dreaded melting problem, leading to questions about the connector’s ability to handle loads up to 600W during peak performance.
While many blame improper connections for these incidents, the real issue might be deeper, involving the uneven distribution of load across the pins. As increasing numbers of cases emerge, it becomes clear that more than just minor design tweaks are needed.
The user in question was using MSI’s adapter with their GeForce RTX 5090 GPU. This adapter, also packaged with MSI’s latest power supplies, requires the yellow tip to be fully inserted into the GPU port. However, even with this feature, the connection failed, indicating a potential flaw that goes beyond user error.
Although thorough investigations have been carried out, no permanent solutions have emerged. If MSI’s specialized connectors are failing, then standard ones might be even more vulnerable. The problem seems particularly prevalent with the RTX 5090 model, yet the RTX 5080 is not entirely exempt.
The power consumption of the RTX 5090, which can soar close to 600W, results in cable temperatures reaching over 100 degrees Celsius, with potential spikes up to 150°C—enough heat to cause serious damage. Fortunately, the GPU in this reported incident remained unharmed.
The situation underscores the need for a redesign or a more robust solution to prevent these critical hardware failures in the future.
