I'm using an OCZ 100W ZX series PSU for my build and it is fully modular. It has a single 12V rail. I'm making all my own custom cables and I want to know if I can get 2 voltages out of 1 connector.
Here is the 5x1 connector that goes into the PSU.
I know the Red is 5V and Yellow is 12V and the 2 blacks are grounds. My question is can I use 1 black wire with each connector, so red + black and yellow + other black to make 2 different strings? I have 12V and 5V LEDs and I see no need to use all of the connectors on the PSU if I can do it with 1. There would be no more than 3 LED strings on the 5 and 12.
Please let me know if this is clear enough and if it is possible.
