Modders 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.

TecLab mods RTX 5090 to run on triple 8-pin connectors, sustains 900W

YouTube modding channel TecLab rebuilt a Galax RTX 5090D HOF OC LAB XOC by removing its dual 16-pin power connectors and soldering in three 8-pin PCIe connectors directly to the power regulators, rewiring sense pins to remove power limits. Using liquid cooling, they pushed the card from 400W up to 900W, drawing over 120A and hitting clock speeds of 3,400 MHz, all through hardware changes alone with no BIOS or software tuning.
