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. --- End quote --- So how would I incorporate the fuse? And do I need one per LEDWIZ? |

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. |

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. |
