TECH NEWS – It wasn’t enough for the power connector on an MSI graphics card to melt once — it happened twice, highlighting a growing problem among RTX 5090 owners.
A Reddit user has reported another case of a melted power connector involving an MSI GeForce RTX 5090 graphics card. In both instances, the GPU’s 16-pin connector melted within a few weeks. It’s not just Ryzen 7 9800X3D owners struggling with repeatedly burned CPUs — RTX 5090 users are facing similar issues. The melting of GeForce RTX 5090’s 16-pin connectors is unfortunately a fairly common problem, but seeing it occur twice in a row is extremely frustrating. Often, user error is to blame, but a combination of factors can also lead to this failure. According to Deja_, the connector can easily melt due to poor design.
The user owned an MSI GeForce RTX 5090 Gaming Trio graphics card, which came with a yellow-tipped adapter. He claims he did not use the native 16-pin cable supplied with the PSU. Instead, he used a Corsair SF1000 power supply, which is ATX 3.1 compatible and, according to the official website, comes with a 12VHPWR cable. Despite this, the GPU melted in July, and after receiving a warranty replacement (RMA) in August, the same issue occurred again less than two months later.
He used the included yellow adapter instead of a 12V-2×6 or 12VHPWR connector, which could explain why the connector melted in just a few weeks. The 4×8-pin to 16-pin adapter is notorious for such issues because it distributes power unevenly. Even if the user claims the adapter was fully inserted into the GPU, that does not guarantee proper power distribution.
Since the result was the same both times, Reddit users speculate that the power supply might also be to blame. These incidents typically result from a combination of factors, and at least two seem to be at play here.
