I'm extending one of my PSU power cables because is to short. the line got 2 black/1 yellow and 1 red (molex) I know the colors have to be matched but if at the other end I end up mixing the 2 black lines, will there be a problem?ps: I already sleeved the cable for that matter I can't see the 2 black cables inside and i forgot to mark them. :)
first of all dont make any home made concoctions you can find those tipe of extensions in a pc store for under a buck and it dosnt mater the black cables are just grounds the important ones are the red and yelow
swapping the black wires will not cause any problems.
Mixing the Two Black Wires doesn't matter becuase the Black Wire = 0V it is common wire used with red and yellow. The Red Wire = 12V and the Yellow Wire = 5V so don't mix the Yellow and Red Wire and be sure to connect the Yellow and Red Wires to the Correct Place in the Connector because if wrong connection made with yellow instead of red it will damage your hardware.
