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.

The 16-24AWG range of the 12V-2x6 cable includes the sideband wires, so 16AWG is stored as the power wire gauge.

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.
