Just want to warn the newer people to computing that mixing cables from the same or different psu's will kill your computer!
I didn't know this and killed a GPU, 3 hard drives and a motherboard by mixing up a cable from a different psu (the cpu, memory was fine).
I used a cable from a different psu and plugged into my GPU and blow every thing up that way.
 
If you can't find a compatibility chart (as above) use a Ohm meter to check out that pin 1 goes to pin 1 on both ends of the cable and do this for ALL the pins as some times they switch pin-outs and what was a 5 volt pin could be a 12 volt pin on a different cable (or a ground).
 
That was an expensive lesson learned the hard way.

If the pinouts are the same as the original cables your good to go.
