Modders power RTX 5090 with 8-pin connectors, drawing up to 900W

By PulseAugur Editorial · [1 sources] ·

Modders have successfully adapted a high-end RTX 5090 graphics card to use three 8-pin PCIe power connectors instead of the newer 16-pin 12VHPWR connectors. This modification, performed by the YouTube channel TecLab, allowed the card to draw up to 900W and reach clock speeds of 3,400 MHz, demonstrating the continued capability of 8-pin connectors for high-power GPUs. The experiment also showed that the card could still operate at respectable speeds with only two or even one 8-pin connector, suggesting a potential reconsideration of connector standards by manufacturers.

    Modded RTX 5090 ditches 16-pin power for triple 8-pin connectors — draws up to 900W and hits 3,400 MHz

    TecLab’s experiment puts the humble 8-pin connector to an extreme test, with the modified RTX 5090 pulling more than 120A while avoiding the newer 12V-2x6 design altogether.
