Kit Developed to Reduce Melting Risk for Nvidia RTX 5090 Graphics Card

    A special conversion kit has been developed to reduce the risk of overheating and melting in the 16-pin power connector on Nvidia’s GeForce RTX 5090 graphics card. Developed by a Reddit user known as “DallasGrave,” the solution replaces the 12VHPWR and updated 12V-2x6 connector with 4 8-pin PCIe connectors. This distributes the electrical load across more connections. The card’s price on Amazon currently stands at $8,500 (approximately 14,450 manats).    The kit does not connect to a cable like a conventional adapter; it is installed directly on the graphics card. A custom cable is soldered to the card’s power lines, bypassing the standard 16-pin connector. Each 8-pin PCIe connector delivers up to 150 W of power. The combined capacity of all the connectors is 600 W, equal to the maximum limit of the 16-pin connector.    The standard 16-pin connector carries 50 A of current through 6 closely spaced power pins. Under the PCI-SIG standard, the upper limit is 9.5 A per pin. The theoretical total limit is 57 A, or 684 W. When the card operates at 600 W, each pin carries approximately 8.33 A. Because the new kit has 12 pins, each pin’s share of the 50 A load drops to 4.17 A. This reduces the risk of overheating and damage.    The conversion kit sends a signal indicating that the full 600 W of power is available to the system. The creator says he tested the device at 800 W using a shunt modification that changes the power limit. The kit can operate as the primary power source or be connected in parallel with the card’s own 16-pin connector. The risk is not completely eliminated with 8-pin connectors either, but they melt less frequently.    DallasGrave is also developing a custom backplate to improve the kit’s appearance. The solution is not limited to the GeForce RTX 5090 or cards from certain manufacturers. The creator says he is preparing compatible models for nearly all versions on the market, including the Nvidia Founders Edition, for production. The release date, price and installation procedure have not yet been announced.
