A Reddit user reported a similar incident again with his MSI GeForce RTX 5090. In both cases, the GPU's 16-pin connector melted in just a few weeks.
Redditor Witnesses Melted 16-pin Connector on MSI RTX 5090 Twice; User Says He Used Corsair SF1000 PSU and the MSI Adapter To Power the GPU
It's not just the Ryzen 7 9800X3D owners who are suffering from burnt CPUs over and over again, but it's the same with the RTX 5090 owners, too. Seeing melting 16-pin power connectors on GeForce RTX 5090 is quite common, but as a user, seeing this twice back-to-back is definitely frustrating. In a lot of cases, it was user error, but in others, it was due to a combination of factors that led to the melting of connectors. Thanks to the poor design of the connector, it's easy to get it melted in no time, and this is what the user u/Deja_ reported in a thread.
The user had the MSI GeForce RTX 5090 Gaming Trio, which ships with the MSI yellow tip adapter. The user says that he didn't use the native 16-pin power cable that ships with the power supply. In this case, he used the Corsair SF1000, a compact power supply that is ATX 3.1 compliant but ships with a 12VHPWR connector cable as per what's mentioned on the official website. Nonetheless, the GPU melted in July, but he received a new one through RMA in August. In less than two months, the connector on the GPU melted again.
He mentions that he used the MSI yellow tip adapter that came with the GPU instead of a single 12V-2x6 or 12VHPWR connector. This might explain why he saw the connector melting in just a couple of weeks. This 4x8-pin to 16-pin adapter is pretty well known for such issues due to poor load balancing. Even if the user says he ensured a proper connection (meaning the yellow tip was completely inside the GPU connector), it still doesn't guarantee that the adapter will have a proper current distribution.
Nonetheless, in both cases, the results were the same, and some are even speculating that it could also be due to his PSU. We know that such cases can arise due to a combination of factors, and we can see at least two here as well.
