Tech Specs: SATA connector 6, PATA connector 2. PCIe 8-pin is 1 single cable plus 1 cable with two 8-pin plugs, so 3 plugs on 2 cables. The two 4-pin PATA plugs are the molex row, which takes the 450 mm to the first plug of that cable. The 12V-2x6 cable is described as a native 600W-capable cable. The wire gauges come from the Cybenetics report. The quick start guide lists 2 single 8-pin PCIe cables for this model, which does not match this table, the Cybenetics report or Hardware Busters. The PSU side has one 12V-2x6 socket, so the dual 8-pin cable takes the 12V-2x6 socket and cannot be used together with the native 12V-2x6 cable. Cybenetics measures 600 mm, 740 mm, 640 mm and 445 mm for some of the same cables, which are not stored.5Measurementcybenetics.com/evaluations/psus/2625Read 16 October 2026Cables and Connectors table gives wire gauge per cable: ATX 18-20AWG, EPS 18AWG, 6+2 PCIe 18AWG, 2x 6+2 PCIe 16-18AWG, 12+2 pin PCIe (600W) 16-24AWG, SATA and Molex 18AWG. The 16-24AWG range for the 12V-2x6 cable includes the thin sideband wires, so no gauge is stored for it. Lengths are Corsair's.

The review says there are no native PCIe 6+2 cables and that the two traditional PCIe cables come from the 12V-2x6 socket of the PSU, so the dual 8-pin cable shares that socket with the native 12V-2x6 cable. The review gives 16 AWG for the CPU and PCIe cables. Lengths come from this single review, since Seasonic's own cable table was not readable. The SATA 750 mm and Molex 690 mm figures match Seasonic's cable table for the CORE GX family, which gives the length to the last plug, so they are not stored.4Retailer pagedekada.com/en/seasonic-psu-atx-31-650w-gold-full-modular-pcie-51-core-gx650-v2-srpcgx651a5a32sf-p-6265.htmlRead 14 October 2026Connector counts: 12VHPWR 1, PCI-Express 6+2 pin 2, Molex 3, SATA 6, 4+4 pin ATX/EPS 2, 20+4 pin ATX 1.
