12v and 5v from the same Molex Connector?
« on: March 24, 2008, 11:19:19 pm »
Since molex connectors have 4 pins, [12v, gnd, gnd, 5v] is it possible to connect the left two to power one item needing 12v, and the right two to a different item which requires 5v?  Do I need to steal 12v from one molex, and rob the 5v off another?  The two items should never interact (NovaMatrix at 12v, Solarberics Secret Motor Driver at 5v), but I was hoping to only have to expose 1 outlet from the power supply for both needs.

Thanks!

Yes, you can do that.

Once all of those connectors and wires get back into the power supply, all of the 12V/5V/GND are commonly wired. So, you could actually tap all the power you want to off of one connector. Providing, you don't draw too much current and melt the insulation....

Super!  That's what I was hoping to hear.  Didn't want to just forge ahead without asking, and fry everything I've all ready mounted.  Thanks a bunch.

What is the best way to attach the Novamatrix?  I'm about to just cut off a floppy drive connector and attach it with some crip on connectors.  Is there a better way?
