Wow, you guys are great! I totally appreciate the quick reply. I did a forum search on PC power supplies but I couldn't find the specific answer I needed. I never even thought that the info would be out there on the net.

Oh by the way when you say bridge do you mean just twist them together right.

So theoretically I could use this to create a remote switch.

    Thanks again. I build a lot of furniture and my cab is looking really awesome but my electronic and computer skill are weak. Some times I think, "Man am I going to be able to do the computer part of this project or am I going to just stare at my $1500 dollar cab wishing it would work." I guess I will find that out soon.

I'm off to test my UV LEDs.

Hey Whammoed are you just messing with me or are you serious?

He's serious..... You can damage the power supply on an ATX unit, if there's no load on the 5V Rail.

The PSU uses that to set up its voltage regulators, they can swing wildly if there isn't a correct load on that rail.

Bummer! I bought this power supply just to run my car amp and LEDs.

Is there any solution to this or should I toss this sucker and look for a AT power supply on eBay?

Fozzy The Bear:

If you're using the 5V supply for your 100 LEDs then you should be OK with it. As long as you remember never to turn it on without the LEDs connected.
