Multiple LED WIZ power ?

Are you using all of the ports on all three ledwizs though? And, are they RGBs or just regular LEDs?

MonMotha:

Power hookup from PC:

* Black ground wire from PC hard disk drive connector to the LED-Wiz "External Ground" (G) terminal.
* Red 5V wire from PC hard disk drive connector to one side of a fuse holder.  Other side of the fuse holder to the two "bank voltage select" terminals on the LED-Wiz.  Install an appropriate size fuse (approximately 2x your maximum calculated current draw - remember 1A = 1000mA).For LEDs with built in resistors for 5V:

* Red 5V wire from the LED-Wiz "bank select" terminal to the anode terminal of each LED.For LEDs without a built in resistor:

* Red 5V wire from the LED-Wiz "bank select" terminal to one side of a suitably calculated resistor.
* Wire (any color, but I like orange, white, or brown since it looks like an "intermediate voltage") to the anode of the LED being powered.  You could also just use the leg of the resistor soldered directly to the leg of the LED for this.  You might consider covering the whole smash with some heat shrink tubing if you do that.For all LEDs:

* Wire (any color, but I like gray, brown, or one color per channel, however a lot of people fairly reasonably use black) wire from cathode of each LED to the appropriate channel on the LED-Wiz.
Note that you're kinda using the LED-Wiz as a terminal strip for bundling the power and ground lines, here.  It works well enough if you don't have a ton of LEDs, but if you've got a lot, you may prefer to daisy-chain the power between the LEDs (or the resistor, for LEDs without an integrated resistor) and the LED-Wiz.  There are other valid ways to do it, but I find what I described above to be the least error-prone.

The wire from the PC to the LED-Wiz should be at least AWG22.  The wire from the LED-Wiz to each LED should be at least AWG26, and you may need bigger to get it to reliably stay in a terminal connection.  If you bus the power from the bank select to the LEDs, use at least AWG22 for that.  I find AWG22 to be a generally workable size that is sturdy but not too big.  If you're going to crimp it, I recommend stranded.  Stranded is also more resistant to breaking when flexed, but solid may be a little easier to work with if you're soldering directly to the LED legs (and then you may want smaller wire, too).  I wouldn't use anything bigger than AWG18 for any of this: it would be major overkill, and generally harder to work with (not to mention expensive).

Note that standard telephone wire is AWG26 solid, but it's not tinned and so is hard to solder, and the insulation doesn't take soldering heat well.  AWG26 solid is also far too small to reliably hold in standard red crimp terminals without folding it over a couple times.

Also, if you've got multi-color LEDs with a common anode, you need to put the resistor on the cathode side between the LED and the LED-Wiz.  Everything else stays pretty much the same.  This is shown in the LED-Wiz docs.

One other thing to make clear here: the +5V output terminal on the LED-Wiz is NOT USED in this configuration and should not have anything hooked up to it.

I've got 30 RGB LEDs, which means I'm using 90 ports between the three LED-WIZs.

Honestly I was all set to power them off the PC, but since there was no loss of brightness using the powered hub, I didn't see any reason to.

Yeah but I have the newer LEDWIZ so I think I have to make use of the Bank voltage select thats on the board. And I'm also using the RGBs from /http://www.paradisearcadeshop.com/en/ The problem I'm having is hooking up/running all three LEDWIZs together.  I'm going to be posting some pics on here today that show how I currently have them running, and see if someone can point out what i'm doing wrong! This shouldn't be this hard to figure out.
