There's no end in sight to the melting of the 12VHPWR graphics connector

The Nvidia GeForce RTX 4090 graphics card is still up to the toughest tasks. This purposeč it is based on the Nvidia GA102 graphics core and has 16,128 CUDA cores available for data processing. 24 gigabytes of GDDR6X graphics memory with a bandwidth of 21 gigabits per second are available for storing intermediate calculations.

The #141 connector marked 12VHPWR provides enough electrical energy. This has a total of 16 contacts available for supplying electrical energy. At full load, this can deliver up to 600 watts of electrical power directly to the graphics card. Therefore, it is not surprising that it can melt during operation, and in certain cases it can even catch fire.

The failure of the 12VHPWR connector is actually due to a connection that is not done correctly to the end. Although Nvidia tried to solve this problem by introducing a new or improved 12V-2×6 connector, there are still many GeForce RTX 4090 graphics cards equipped with the previous connector. . Therefore, it is not surprising that service technicians encounter melted connectors on a daily basis.

If you also have a GeForce RTX 4090 graphics card with a 12VHPWR connector, we recommend that you follow Seasonic's instructions. This recommendation recommends a minimum distance of 35 millimeters between the connector and the bend of the power cable. The best effect will be achieved by using a homemade hair dryer. With the additional heat, we will be sureč bend the cable more easily, and at the same time it will stay in the desired position more easily. A trick that is definitely worth trying.
