The mod works by soldering a small pickup board directly to the contacts of the card's 16-pin header. That board feeds a second PCB carrying two 8-pin PCIe sockets, so the card ends up drawing power through three cables in total. According to DallasGrave's post on r/pcmasterrace, each conductor now carries roughly 3 A, and the wires never crossed 40°C during a 48-hour run at 550 W, even at the soldered joint.

Those figures come with a caveat: they are the modder's own measurements, and more test data is apparently still to come. They nonetheless contrast sharply with what independent testing has shown. Last month, Hardware Unboxed watched its RTX 5090 power cable reach 175°C with a single wire pulling around 22 A, and testing by Korean outlet QuasarZone, reported in September 2026, found the Founders Edition's 16-pin connector exceeding 90°C under heavy load, hotter than the GPU die itself.

The 12V-2x6 revision of the connector was supposed to fix the melting problem, and in early 2025 NVIDIA declared the 16-pin melting issues over, pointing to the updated connector on the RTX 50-series. The first melted RTX 5090 Founders Edition was reported shortly afterwards, in that case with a third-party cable. Since then, several RTX 5090 power connectors have reportedly melted, including one on a card running an undervolt with a -100 W power limit.
