Either Corsair AX760 or an older AX650/750/850 and buy the modular cable kit...
Or buy a Silverstone Strider and sleeve it yourself, or get somebody else to.
You could probably buy a Silverstone and pay somebody to sleeve it and get it cheaper than an AX760 with braided cables.
The Corsair braided cable kit isn't particularly good either, so it would look better with the Silverstone.
Or, just get Bitfenix extensions instead of an entire kit.
