i currently have all black cables that came with my corsair rm850 but they just look thin and abit tacky. so im looking for some red ones to go with my build. but, the ones im using now has 2, 6=2 pin connectors(i need a 8 and 6 pin) on one cable. online i can only find them separate, will this make a change? also im not wanting yo buy a full set just the cables for my gpu's.
