Title: Power without a PC?!
Post by: Jellyman_4eva on April 08, 2005, 04:58:13 pm

Hi all,

Just a quick question for an expert I guess! I want to use illuminated buttons on my control panel. The panel is using an USB IPAC. However the control panel is actually a seperate unit to the rest of the arcade machine (Where my PC is), my control panel controls link with a USB cable which goes from my control panel to the arcade machine, but how can I get power easily for my control panel!! I was thinking of just using a PSU on its own (As it has the necessary 12V + 5V I need and I aint no electrician!) but without a motherboard how do I make it come on!!

I would prefer a more elegant solution but as of yet I can not think of one... any help?!

You short 2 pins, I forget which ones.

Can't you use the 5v a USB cable (or iPac) supplies?  Do those things need 12v?  You'd probably be best to make a custom connection.  Use a 6-pin connector that you make, for the 4 USB connections and some powers.

you could also get the older style pc power supply
not atx. I can not think of the name right now.
you do not have to short out the two wire on them
or an old arcade power supply. those you can adjust the voltage

Pins 14 and 15 on an ATX PSU will simulate a load and power up the PSU.

Here's the pinout for a std ATX PSU

Yup... Connect a wire between the green wire & a black wire...
It'll work then.
