Reddit user Dallas Grave has created a 'Quad 2x8 Header Conversion' for RTX 5090 graphics cards, mounting four 8-pin PCIe connectors directly on the card. The mod taps the 12V-2x6 header contact points, allowing the 16-pin connector to be used alongside or bypassed entirely. By spreading the load across twelve wires instead of six, each conductor carries roughly 4.1 to 4.4 A at 600 W, with wire temperatures dropping by approximately 20°C.
The sense pins are rated for 600 W, and testing reportedly reached 800 W with the PCB at about 45°C. Installation videos and a 24-hour sustained load test are in production, with custom backplates being developed for a factory-like appearance. Versions for most cards, including Founders Edition, are entering production as connector melting reports persist despite safety measures from MSI, ASUS, and ASRock.
