Even Regular Checking Couldn’t Prevent RTX 5090 Cable from Melting
The RTX 5090 user shared that the 12VHPWR cable, which he checked systematically, melted. Melting problems at contact points and things to pay attention to.
Problems with 16-pin power ports in the graphics card world force users to be cautious. But sometimes being too careful can cause unexpected damage to the hardware.
A new incident shared on Reddit caused RTX 5090 owners to question their habits of checking 12VHPWR contacts again. After checking at regular intervals, the user realized that the cable was melting.
Frequent Control and Contact Problems
Reddit user u/KusKundale noticed that the 16-pin port and cable were burned during routine checks on the RTX 5090 graphics card. The user stated that he removes and reconnects the cable every three months and manually presses the contact every month to make sure it is properly seated.
Experts warn that frequent removal and installation of 16-pin power connectors may damage the pins. It is said that such a process weakens the structure of the connector and increases the risk of melting. This situation experienced by the user shows that too much intervention can have negative effects on the life of the hardware.
The user shared that he used a Corsair Type 4 12VHPWR cable in his system and that the graphics card was mounted vertically. However, it is stated that the cable used is not in the current 12V-2×6 standard and the power supply is not compatible with ATX 3.1 or PCIe 5.1. These details reveal that there are some deficiencies in the installation of the system that may affect contact safety.
Recommendations for Hardware Security
It is of great importance for RTX 50 series graphics card owners to follow the instructions shared by the manufacturer. Instead of frequently checking the connection points, making sure that they are fully seated in the first position is generally considered sufficient.
It is a critical step for users to always avoid forcing the contact points to prevent terminal damage. If the contact point is established securely, there is no need to systematically apply pressure on it. In order to ensure the long life of your hardware, it is considered the safest way to stick to the manufacturer’s instructions for such sensitive contacts.
Do you think these melting problems in the graphics card power cables are entirely due to user error, or is there a fundamental flaw in the design?
