I have a question regarding this power supply as well. The one from Twisted Quarter that is.
For my system, I will have 20 of the 5v LED Lamps from Ultimarc

http://www.koolertek.com/computer-parts/pc/Logisys-15-Sound-Activated-Cold-Cathode-Kit-Red-212p1167.htmThat's all I need powered. I, like the OP, currently have this all running on an extra PC power supply. I'd like to change this to an arcade power supply, like the one from twisted quarter.
http://www.twistedquarter.com/index.php?main_page=product_info&cPath=1&products_id=4Now, like someone said before, typical LED's are in the 20-30 mA range.
Then my LED light bar is powered by 12v
And my cold cathode light kit says it is 12v, with an input current of 700mA
So I have three real questions.
1.) Is the twisted quarter power supply powerful enough to run all my lights I've mentioned? I think that it would be, based on the numbers I've been looking at, but I just want to confirm...
2.) How does the power supply work exactly? The picture is pretty small on their site, but from what I can tell, it looks like there are just different screws on the front, used for the different voltages. So I assume it's just as simple as wiring up both the wires from the cold cathode and the LED light bar to the 12v, and then all my LED's to the 5v line? Is that correct?
3.) Lastly, about the ground wire. My LED's are run through my LED-Wiz, but the LED marquee bar, and the cold cathode are not connected to the LED-Wiz at all. So I'm looking at three separate ground wires. Could I just have one ground wire connected to the LED-Wiz, one going to the marquee light, and one to the cold cathode, and then just wire all three ground wires to the Ground connection on the power source? I'm obviously not an electrical genius here, so I wasn't sure how that worked, and if ground was ground, and they could all be run together.
Thanks!
