The fuse is highly recommended.

So how would I incorporate the fuse? And do I need one per LEDWIZ?

MonMotha:
Just put a fuse in-line with your supply voltage (between the power connector on the PC and where you're hooking it up to your LED-Wiz, etc.).  One fuse for the whole setup should be fine.  Size it about 2-3x your anticipated maximum current draw.

I'm still in the dark on how to run all of the wires/grounds and stuff. Is there a diagram somewhere I could follow? A step by step sorta thing? I'm trying to hook up three 32 port LEDWIZs, so I need a diagram that shows how to run all three. I'm just not getting it! Sorry guys!

Really? Nobody has a picture/diagram on how to do this? :banghead:

I ended up using a powered USB hub to power three LED-WIZs. Not sure if I just got lucky but I've confirmed the LED's all run at 100% brightness, and it saved having to deal with splicing into the PC's power supply.
