GeForce RTX 5090: Individual reports of melting connectors
Caution is also advised with Nvidia's new generation of graphics cards. Cables and connections can still melt.

The heat problems with the 12V-2x6 connector do not appear to have been fully resolved with Nvidia's new generation of graphics cards. The first reports of melted connectors when using a GeForce RTX 5090 are currently doing the rounds. In the worst cases, this leads to defects in the power supply or the graphics card itself.
At the weekend, a Reddit user shared pictures of his Nvidia GeForce RTX 5090 Founders Edition. The connections on both the graphics card and the power supply unit show heat damage; one of the 12-volt pins has melted.

The power cable used here comes from the third-party supplier Moddiy. Neither the original cable from the power supply (Asus ROG Loki 1000 Watt) nor Nvidia's official adapter were used. Third-party cables and adapters already led to defects in the GeForce RTX 4090. However, according to the user, he had already used the same power supply and cable with a GeForce RTX 4090 before – without any problems.
With a real electrical power consumption of 500 watts and more, the GeForce RTX 5090 puts even more strain on cables and connections. More than 80 watts run through each of the six 12-volt wires. The four sense pins at the top of the connector are actually intended to ensure that the connectors are seated correctly. However, crooked contact and therefore uneven current distribution cannot be ruled out.

Two cases with potentially loose plugs
In a second case, the Youtuber "Toro Tocho Reviews" melted five wires on the power supply (FSP Hydro GT Pro 1000 Watt); here with the enclosed FSP cable. The graphics card itself is undamaged. The user himself suspects that the power supply connector was probably not 100% secure.
In the third known case, a tester from the Chinese publication PCM switched several times between the GeForce models RTX 5090D (China-exclusive), RTX 5080 and RTX 4090. Here too, the connectors melted both on the power supply side and on the graphics card. PCM found damage on the RTX 4090. It is unclear how hot the connectors got on the other models.
The reports show: Anyone who was able to get hold of an RTX 5000 graphics card should continue to take care. The plugs must be firmly attached to the power supply and GPU. Particular care should be taken when using third-party adapters or cables.
