They might sell something, but they also recommend CableMod for additional/custom cables for the ROG PSUs. CableMod already sell the new 12 pin PCIe power cables for them (might be custom only, not sure if they had prepackaged ones when I last looked). The CableMod classic cables are identical to the ones supplied with the Thor. (Just remember to get the correct series, the PSU end is not standardised across the industry.)
