All lengths have a tolerance of 10 mm, the PATA cable 25 mm. PATA plugs are the 4-pin Molex plugs. The 12V-2x6 to dual 8-pin cable counts as PCIe 8-pin, so there are 4 PCIe 8-pin plugs on 3 cables. It starts at the 12V-2x6 socket of the PSU, so it shares that socket with the 12V-2x6 cable. Hardware Busters and Cybenetics list 3 PCIe 6+2 cables with 3 plugs and no dual cable, which does not match the maker's list. The page does not rate the 12V-2x6 cable.

The report lists 3 PCIe 6+2 cables with 3 connectors, which does not match the maker's dual 8-pin cable. The 16-24AWG range for the 12V-2x6 cable includes the thin sideband wires, so no gauge is stored for it.
