Source1Maker product pagecorsair.com/us/en/p/psu/cp-9020285-na/rmx-series-rm750x-fully-modular-power-supply-cp-9020285-naRead 15 October 2026Cable listing: 1 ATX 24-pin 610 mm, 2 EPS 8-pin (4+4) 750 mm, 2 PCIe 8-pin (6+2) cables with one plug each, 1 PCIe 12V-2x6 to Dual 8-Pin (6+2) cable with two plugs, 1 PCIe 12V-2x6 (12+4) cable, all three PCIe cable types 650 mm, 2 SATA cables with 4 plugs each (505 mm to the first plug, 115 mm spacing, 850 mm total), 1 PATA cable with 3 plugs (550 mm to the first plug, 100 mm spacing, 750 mm total). 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.

All lengths have a tolerance of 10 mm. PATA plugs are the 4-pin Molex plugs. The listing and the quick start guide say 12VHPWR, but the Corsair 12V-2x6 explainer lists the SF Series cable as a 12V-2x6 cable. The maker names it both ways, so it is stored as 16-pin PCIe. The page does not rate the cable. The 600 W rating comes from the Cybenetics report. Gauges come from the Cybenetics report.2Owner's manualcorsair.com/us/en/explorer/diy-builder/power-supply-units/corsair-sf-seriesRead 15 October 2026SF750 included cables: 1x ATX 24-pin 300 mm, 2x EPS 8-pin 400 mm, 2x PCIe 8-pin 400 mm, 1x 12VHPWR (12+4 pin) 400 mm, 1 SATA cable with 4 straight plugs, 1 with 4 right-angle plugs and 1 PATA cable with 3 plugs.4Maker product pagecorsair.com/us/en/explorer/diy-builder/power-supply-units/which-corsair-psus-have-a-12v-2x6-connectorRead 15 October 2026SF Series (750W / 850W / 1000W): 12V-2x6 cable (Type-5 to 12V-2x6). The cable runs from two 8-pin Micro-Fit sockets on the PSU to a 12+4 pin plug, as the Hardware Busters review says. It is a cable of its own, not an adapter on another cable. The page does not rate the cable.6Measurementcybenetics.com/evaluations/psus/2352Read 15 October 2026Cables and Connectors table: ATX 20+4 pin 16-20AWG, 2 x 4+4 pin EPS 16AWG, 2 x 6+2 pin PCIe 16AWG, 12+2 pin PCIe (600W) 16-24AWG, 2 SATA cables with 8 plugs in total 18AWG and 1 Molex cable with 3 plugs 18AWG, no in-cable capacitors. The 16-24AWG range of the 12V-2x6 cable includes the sideband wires, so no gauge is stored for it. The 600W rating is printed next to the 12-pin cable. Cybenetics lists 410 mm for the EPS and PCIe cables and 110 mm to the first SATA and Molex plug, which are not stored. Corsair's lengths are stored.7Reviewhwbusters.com/psus/corsair-sf750-atx-v3-1-psu-reviewRead 15 October 2026Cables page: the modular panel has nine sockets and the 12V-2x6 cable uses 2 x 8-pin Micro-Fit sockets, with no native 12V-2x6 socket. The cable table matches the Cybenetics report. The review text confirms two 6+2 pin PCIe cables and one 12+2 pin cable.
