GoKawiilModders replace RTX 5090's 16-pin connector with three 8-pin plugs, no overheating
Brazilian YouTube channel TecLab modified a Galax HOF OC LAB RTX 5090 to run on three 8-pin Mini-Fit Jr. power connectors instead of Nvidia's dual 16-pin design, by rewiring the Sense 0 and Sense 1 pins to fool the card into recognizing the new configuration. The card still hit its full 575W TDP and ran stable at 3.4GHz across load tests up to 900W and 120A peak current, with temperatures staying around 35°C and no firmware changes needed.
GoKawiil's interpretation of the reporting above, not reported fact.
Nvidia's 16-pin 12V-2x6 connector has been linked to repeated melting incidents on high-power cards like the 5090, raising safety concerns across the industry. This mod suggests that splitting current across more, smaller connectors could be a safer and more thermally stable alternative, potentially informing future GPU power designs or aftermarket cooling solutions.
- TecLab successfully ran an RTX 5090 on three 8-pin connectors instead of the stock 16-pin design.
- The modified card sustained full 575W TDP and stayed stable even at 900W and 120A peak loads.
- Results hint that distributing power across more connectors may reduce the melting risk tied to Nvidia's 16-pin connector.
Corsair 600W PCIe 5.1 12V-2x6 Cable — If you're running a 575W monster like the RTX 5090 and don't fancy hand-modding 8-pin connectors, a proper native 12V-2x6 cable from your PSU maker is the sane route. Corsair's Type-4/Type-5 600W cable ditches flimsy adapters for a single direct run, and its updated 12V-2x6 terminals are designed for firmer seating — the exact contact issue at the heart of these melting-connector stories.
