Most psu's come with cables braided these days and some like the Bitfenix Fury range come with individually sleeved cables. The price is high because of the sleeving and the psu's are just mid range units that would cost around £30 less each if it wasn't for the cables. The Op is asking about ribbon cables though. Do you mean the flat non-sleeved cables? My Seasonic has these as do some of the Corsair units and the excellent Coolermaster V series (Seasonic built).
