The page says primary cables are 16-20 AWG and APH Networks says 18 AWG, so gauges are stored only for the 12V-2x6 cable.6Reviewaphnetworks.com/reports/fractal-design-ion-3-gold-1000w/2Read 15 October 2026Page 2: 16 AWG wires on the 12V-2x6 bundle only, everything else 18 AWG. The 12V-2x6 header is 16-pin 600W. Only the 12V-2x6 gauge is stored because KitGuru gives a 16-20 AWG range for the other cables. The APH list of SATA cables disagrees with the maker, so the maker table is used.

Cybenetics and Hardware Busters measure 450 mm for the SATA and Molex cables and 155 mm for the SATA spacing. The maker figures are stored. The 12V-2x6 to dual PCIe cable and the native 12V-2x6 cable use the same 12V-2x6 socket, so they are alternatives. Gauges come from the Cybenetics report.5Measurementcybenetics.com/evaluations/psus/3167Read 15 October 2026Cables and Connectors table: ATX 20+4 pin 600 mm 16AWG, 2 x 4+4 pin EPS12V 700 mm 16AWG, 3 x 6+2 pin PCIe 550 mm 16AWG, the 2x 6+2 pin PCIe cable 550 mm 18AWG, 12+4 pin PCIe 600 mm (600W) 16-24AWG, 2 SATA cables with 8 plugs in total 450 mm + 155 mm x 3 18AWG and 1 Molex cable with 4 plugs 450 mm + 150 mm x 3 18AWG. The 16-24AWG range of the 12V-2x6 cable includes the sideband wires, so 16AWG is stored as the power wire gauge. The report lists the dual PCIe cable as 2 cables with 2 connectors, while Lian Li and Hardware Busters count 1 cable with 2 plugs. The maker count is stored.6Reviewhwbusters.com/psus/lian-li-sx1000p-1000w-atx-v3-1-psu-reviewRead 15 October 2026Page 2: the modular panel has a dedicated 12V-2x6 socket, five CPU and PCIe sockets, four peripheral sockets and the split 18+10-pin motherboard pair. The bundle has three single PCIe 6+2-pin cables and one cable from the 12V-2x6 socket to two 6+2-pin plugs. That cable and the native 12V-2x6 cable are alternatives, so the five legacy PCIe plugs and the native cable cannot all be used together.
