Tolerance 10 mm. The 12V-2x6 to dual 8-pin cable plugs into the 12V-2x6 socket, so it counts as 2 PCIe 8-pin plugs on 1 cable and cannot be used together with the native 12V-2x6 cable. Tech Specs tab: SATA 6, PATA 2. A January 2025 copy of the tab and the prog-it listing also print EPS 2 and PCIe 3. The quick start guide agrees with the cable table. The 2 PATA plugs are stored as 4-pin Molex. The gauge and the 12V-2x6 rating come from Cybenetics.3Owner's manualcorsair.com/explorer/diy-builder/power-supply-units/corsair-rme-series-2025Read 16 October 2026Included cables for the RM650e: 24-pin 610 mm, 1 EPS 4+4 pigtail cable of 850 mm in total, 12V-2x6 650 mm, 12V-2x6 to 2x (6+2) 650 mm, 1 PCIe 8-pin (6+2) 650 mm, 1 SATA cable (4 SATA) and 1 SATA/PATA cable (2 SATA, 2 PATA).5Measurementcybenetics.com/evaluations/psus/2628Read 16 October 2026Cables and Connectors table: ATX 24 pin 610 mm 18-20AWG, 4+4 pin EPS12V (740 mm then 100 mm) 16-18AWG, a 2x 6+2 pin PCIe cable 650 mm 16-18AWG, a single 6+2 pin PCIe cable 640 mm 18AWG, a 12+2 pin PCIe cable 640 mm (300W) 18-24AWG, SATA and Molex cable (450 mm then 100 mm to the second SATA plug, then the 2 Molex plugs at 100 mm spacing) 18AWG and a 4-plug SATA cable (450 mm, 100 mm spacing) 18AWG. DUT Notes: this unit ships with an 18AWG 12+4pin PCIe cable, so 18AWG is the power wire gauge and the 24AWG end of the 18-24AWG range is the sideband wires. The 300W rating of the 12V-2x6 cable is printed by Cybenetics and Hardware Busters, and Corsair states none for this cable. Corsair's lengths are stored. They equal the report's or are 10 mm longer.6Reviewhwbusters.com/psus/corsair-rm650e-atx-v3-1-psu-reviewRead 16 October 2026Technical specifications: 2x EPS (1 cable), 3x PCIe 6+2 pin (2 cables), 1x PCIe 12+2 pin (300W), 6x SATA (2 cables), 2x 4-pin Molex (1 cable). The page shows the same cable table as Cybenetics. The modular panel has eight sockets, including a 12V-2x6.
