Modders at the Brazilian YouTube channel TecLab have an RTX 5090 running on three standard 8-pin PCIe connectors instead of the 16-pin design that keeps melting on high-end NVIDIA cards. The team stripped a Galax GeForce RTX 5090D HOF OC LAB XOC down to the bare PCB, removed both native 16-pin inputs, and soldered three 8-pin connectors straight to the power regulators.
Sense pins were rewired so the card would still request full power, with liquid cooling keeping temperatures in check. During a livestream, the modders ramped the card from 400 W to 900 W across the three cables, pulling over 120 A while holding a 3,400 MHz clock.
Two connectors still delivered 66 A at 3,200 MHz, and even a single 8-pin managed 65 A at 3,100 MHz. The mod stayed entirely at the hardware level, with no BIOS or software tweaks involved. Throughout the test, the modified RTX 5090 stayed within its power and thermal limits, and passed all tests with flying colors.
