All lengths have a tolerance of 10 mm, the PATA cable 25 mm. PATA plugs are the 4-pin Molex plugs. The 12V-2x6 to dual 8-pin cable counts as PCIe 8-pin, so there are 4 PCIe 8-pin plugs on 3 cables. It starts at the 12V-2x6 socket of the PSU, so it shares that socket with the 12V-2x6 cable. Hardware Busters and Cybenetics list 3 PCIe 6+2 cables with 3 plugs and no dual cable, which does not match the maker's list. The page does not rate the 12V-2x6 cable. The Cybenetics report and Hardware Busters list it at 600 W. Gauges come from the Cybenetics report.2Owner's manualcorsair.com/us/en/explorer/diy-builder/power-supply-units/corsair-rmx-seriesRead 15 October 2026Included cables: 1x ATX 24-pin 610 mm, 2x EPS/ATX12V 8-pin (4+4) 750 mm, 1x PCIe 12V-2x6 (12+4) 650 mm, 2x PCIe 8-pin (6+2) 650 mm (RM750x), 1x 12V-2x6 to Dual 8-pin (6+2) 650 mm (RM750x only), 2x SATA with 4 plugs 850 mm, 1x PATA with 3 plugs 750 mm.8Measurementcybenetics.com/evaluations/psus/2406Read 15 October 2026Cables and Connectors table: ATX 16-20AWG, EPS 18AWG, 6+2 pin PCIe 16-18AWG, 12+2 pin PCIe (600W) 16-24AWG, SATA 18AWG and Molex 18AWG, no in-cable capacitors. The report lists 3 PCIe 6+2 cables with 3 connectors, which does not match the maker's dual 8-pin cable. The 16-24AWG range for the 12V-2x6 cable includes the thin sideband wires, so no gauge is stored for it. Cybenetics lists the SATA cable at 500 mm, which is not stored.9Reviewhwbusters.com/psus/corsair-rm750x-atx-v3-1-psu-reviewRead 15 October 2026Cables page: the same cable table as the Cybenetics report. The text says the modular board has ten sockets, one of them 12V-2x6, and no pair of 8-pin sockets for the high-power PCIe connector.

The table leaves out the third single 6+2 pin PCIe cable that the manual, the launch article and the Cybenetics report list, so 3 single cables and the 650+100 mm cable are stored. Length is to the first plug. Gauges come from the Cybenetics report.2Owner's manualdrive.google.com/file/d/1opHpL_4HrcZ0yMicOTelF5psguN19QCk/viewRead 15 October 2026Contents table, 850W row: 24/20-pin x1 (620 mm), 8-pin CPU x1 (750 mm), 4+4 pin CPU x1 (750 mm), 8/6+2 pin PCIe x3 (650 mm), 8/6+2 pin x2 on one cable x1 (650+100 mm), 12V-2x6 x1 (450W, 650 mm), 4 SATA x1 (300-15-15-15 mm), 4 Y-type SATA x1 ((400-150 mm)*2), 4 SATA x1 (400-150-150-150 mm), 4-pin peripheral x1 (500-150-150-150 mm). The manual prints 400 mm for the Y-type cable, while the maker page prints 375 mm and Cybenetics measured 380 mm, so 375 mm is stored.4Measurementcybenetics.com/evaluations/psus/2747Read 15 October 2026Cables and Connectors table: ATX 20+4 pin 625 mm 16-22AWG, 4+4 pin and 8 pin EPS 745 mm 16AWG, 3 single 6+2 pin PCIe 645 mm and one 6+2 pin PCIe cable with two plugs (645 mm then 100 mm) 16AWG, 12+4 pin PCIe 650 mm (600W) 16-26AWG, SATA 380 mm with 4 plugs in a Y shape, SATA 310 mm with 4 plugs, SATA 400 mm with 4 plugs and one Molex cable of 495 mm with 4 plugs, all 16AWG. The 16-26AWG range of the 12V-2x6 cable includes the sideband wires, so no gauge is stored for it. The report prints 600W for that cable, but the maker rates it 450W for the 850W model, which is stored. The maker's lengths are stored.6Press articletheoverclocker.comRead 15 October 2026Included cables table, 850W: MB 20+4 pin 620 mm x1, CPU 8 pin 750 mm x1, CPU 4+4 pin 750 mm x1, GPU 6+2 pin 650 mm x3, GPU 6+2 pin 650+100 mm x1, GPU 12V-2X6 (450W) 650 mm x1, SATA extender 345 mm (300+15+15+15), SATA-Y 525 mm (375+150), SATA 850 mm (400+150+150+150), PATA 950 mm (500+150+150+150).
