I took a look at that and I'm not to sure on what inline fuse to get?

That's no small amount of current.

Keep in mind that a USB port is specd to deliver +no more than+ 500ma, period. And if it's not a powered hub, it'll only deliver a fraction of that before it either crowbars and shuts down, or worse. 500 ma, using 20ma LEDs amounts to 25 LEDs at the absolute maximum, and that's not counting the current draw from the LEDWiz itself.

Bottom line, you just about HAVE to make use of the external power connectors on the LEDWiz, esp if you ever expect to light most of the LED's simultaneously.

You might get away with not doing that if you only light a few LEDs at a time, but that can be pretty tricky.

When you do grab a 5v DC wallwart, just make sure it's not one of those 500ma output wienies. You'll be back in the same boat.

You'll want to get an external harddrive supply or something similar that can output 2-3amps (2000-3000 ma) of current.

(EDIT) Connecting to the PC Supply with a fused line is also good as in the link that Hoopz points to.

Thanks for your response! But you might aswell been speaking Russian because I'm terrible when it comes to electrical terms. lol
Nephasth:
I have 2 PACLED64s running a total of 26 RGB LEDs (13 RGBs each, for a total of 78 individual LEDs). The LEDs are externally powered by the computer's PSU. Each PACLED64 is connected to one of the PSU's Molex drive connectors' 5V lines. I don't have an inline fuse for either of them, and haven't experienced any problems. Very easy to tap into the computer's PSU to power your LEDs, and this would be my recommendation as well.
Green Giant:
You can get your power from the PC power supply.  You simply need any old molex connector you can hack apart so that you can avoid cutting up your PC.

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

drventure:
really, the only reason for the fuse is because everything is being hand wired, and it can be easy to make a mistake.

If you do, and there's a fuse, no harm, no foul, the fuse bites it, you figure out what went wrong, fix it and replace the fuse.

Without a fuse, you might end up frying a rail in your PSU or worse, which would sucketh greatly  :)

Just depends on your confidence level  ;)
