A Reddit user has reported a second instance of the 16-pin power connector melting on his MSI GeForce RTX 5090 graphics card within just a few weeks. The user, who goes by u/Deja_, described using a Corsair SF1000 power supply and the MSI yellow tip adapter rather than the native 16-pin power cable that comes with the power supply. Despite ensuring the adapter was securely connected, the connector melted in July. After receiving a replacement through RMA in August, the same problem occurred again.

Such issues are not uncommon among RTX 5090 owners, with melting adapters often linked to poor load balancing, especially with the 4x8-pin to 16-pin adapter included with some models. Even when properly installed, these adapters may not distribute current evenly, leading to overheating. Similar reports suggest that a combination of adapter design and possible power supply compatibility issues could be contributing factors. Some users speculate that switching to a direct 12VHPWR connector may help prevent further problems.
