This hardware mod adds<\/a> two additional 8-pin power connectors to the RTX 5090 graphics card. It keeps wire temperatures below 40\u00b0C under load.<\/p>\n

When it comes to melting NVIDIA RTX 12V-2×6 connectors, third-party adapters aren’t the best solution, since they can also melt. Fuses also do not solve the problem – they only turn off the graphics card and the PC. It seems the mod by Reddit user DallasGrave avoids these shortcomings.<\/p>\n

The modder attached an add-on board with two 8-pin power connectors to the top of his MSI RTX 5090. This way, the video card is powered by three connectors: the original 12-pin and two additional ones. This reduces the current through the wires, helping prevent overheating.<\/p>\n

“A printed circuit board is soldered to the pins of the original 12VHPWR connector, which allows power from two 8-pin connectors. Power consumption and temperature of all wires are significantly lower, with approximately ~3A. The card was operated at full load for 48 hours at 550W, and the temperature of the wires never exceeded 40\u00b0C even at the connection point,” DallasGrave describes the design and its operation.<\/p>\n

ASUS\u00a0explored<\/a>\u00a0another promising solution to the melting-connector problem.\u00a0The video card has a modified power supply circuit, and the PSU operates at 48 V instead of 24 V, which not only reduces current but also increases power consumption.<\/p>\n
