Although Nvidia has clarified the power cable melting problems in the GeForce RTX 4090, the problems are not completely resolved. Finally, there have been a number of new cases showing that the 16-pin power connector and external connectors on the video card are insufficient.Increasing complaints about RTX 4090 cables
If we recall, this problem started in October when multiple users said their power cords were burnt or melted. Then in November, Nvidia confirmed 50 cases worldwide, saying users connected adapters incorrectly. However, complaints from users on the Reddit platform continue to increase.
For those who don’t know, the RTX 4090 was introduced with 16-pin 12VHPWR connectors and naturally offers support for ATX 3.0 power supplies. However, let us remind you that converter support is offered to users who have an ATX 2.0 PSU. So far, there has been no burning or melting problem in ATX 3.0 supported PSU connectors.
At this point, a Reddit user, who stated that he connected the connector in accordance with Nvidia’s instructions, shared images showing that the power cable melted after six months of use. In addition, the flagship GPU was primarily used for artificial intelligence models rather than gaming. Another user states that only one of the two RTX 4090s he bought had a problem.Finally, another user, who said that the power cable melted, stated that he used the RTX 4090 with a third-party Corsair SF750 platinum adapter and limited the GPU to 70 percent power. So there is no big load on GPU and PSU. Nvidia did not make any statements about the new cases. However, the best solution to the burning or melting problem seems to be to avoid external adapters and turn to the ATX 3.0 PSU.
