remove the yellow and one black wire.  Attach the red and black wires to the 5V and ground on your LED-Wiz.

So that I understand you right. I get an old molex connecter, take away the yellow and one black wires, attach the red and black wires to the 5v and ground on the LED-Wiz. And then what? Do I connect the molex to the power supply? So basicly I would have one male molex and one female molex? What about hooking up three LEDwizs? Do I do the same for all of the LED Wizs then? Because I don't think I have that many molex connecters on my power supply! Sorry if I seem like an idiot, but this kind of stuff is way over my head.

BobA:
One molex connector will feed many LEDwiz's.  Remember some lines have multiple connectors on the same yellow black black red so try to use one that is not connected to all your drives.  The max current at 5V is determined by your power supply.  Even with all your drives connected to the same line the load should be light.

Yeah, you need a female molex connector you can hack up so that you can easily plug it into your PC power supply when ready.

Off of this one molex you can easily solder/connect 3 wires for the 5v to each led-wiz and another 3 wires for ground.


A single molex can easily put out plenty of juice for 3 led-wiz's.  I am powering my two led-wiz's with a connection just like this.

I don't suppose you could hook me up with a diagam of some kind could you? I just don't wanna fry somthing! there's alot of money sitting here. lol

MonMotha:
The fuse isn't to protect the power supply, it's to (hopefully) protect the stuff you're powering.  You can pull a *lot* of power off a PC supply.  Generally in excess of 30 amps.  With small wire, the supply may not reliably detect a short circuit (due to the resistance of the wire) and won't shut down.  You can easily melt wires in these situations.  Imagine if some fault dumped all that power into a chip.  You might well literally blow it off the board.

The fuse is highly recommended.
