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.
