Small ATX PSU into an A500 PSU casing - a few questions...

[mingle]

Hi,

I've managed to find a very nice little (95W) ATX PSU which will fit very nicely inside an A500 PSU casing, but I have a couple of questions:

1: Which power lines on the ATX connector do I need to wire up to the 5 pins of the A500 power connector?

2: I'd like to keep the on/off switch A500 PSU casing, but since an ATX supply used a 'momentary' on/off switch, is it safe to wire up the A500 on/off toggle switch to the two ATX on/off wires? If not, how can I retain the A500 on/off swith?

Any help or commenst greatly appreciated!

Cheers,

Mike.

I thought the best way to use an ATX supply was to set it up to always be on, and then switch the AC input voltage on and off.

If you can just use a momentary switch, I can't imagine there'd be a problem with a quick flick on-then-off of the power switch, or maybe even there's a momentary style switch with a spring that would fit in place of the original one.

As for which lines, well, I'd say you need a voltmeter to figure out the +5V, +12V, -12V, and ground wires (though they probably are color coded, yellow is usually +12, red +5, and black ground. Blue for -12v? Who knows.)

Hi,

Managed to find a few very useful guides on how to do exactly what I'm after...
