how should i power my external case? it will have 2 cold cathodes, 3-6 fans(atleast 3)and a pump(swiftech mcp655) i have an extra psu but i would hate to use a flip switch just to turn on a pump and ideas.
 
Well you can always run a trigger wire to your external case. Or you can purchase two wireless computer starters... put them on the same frequency so that when you press the start button both machines will boot ;)
 
Option #3:
Buy an old AT powersupply. They are independently switched, so you don't need a motherboard or whatnot to power it on. A small AT PSU would power everything you need. Hell...you could probably leave it on 24/7 to keep your W/C gear running and but just switch your comp off.

I put a left over PSU in my external box.

The major reason was simple. Testing and filling. With an external box, you usually have more hose, etc.. so it takes a bit to fill the whole system. Having it connected to its own PSU is a life saver, You are turning it on and off a lot during filling, having it on its own PSU that you can turn on and off at will is a great feature.

There are 2 ways to mod a PSU so it doesn't need to be connected to a mother board... one way is to use a paper clip (you can search the forums for that one) or you can twist one black and the green wire together to jump the mobo connector.

Heres my work log where I did that

PSU Mod

and heres my external box, and where i modded the PSU a little more

ext box

i hope this helps!

THe PSU i had left over was a cheap 500w that came in my $35 broadway.com case.... so it was a perfect use for the PSU.

Like the others said you could buy and old AT PSU, those work too.

You could always rig it to turn on as soon as you plug it in. That's what I did with mine. I was going to put a switch in for the pump, but what's the point? You'll never turn it off and you don't want to risk it getting shut off on accident.
