Compaq ATX Connector Wiring

Hi,
I have a Compaq 5320US with a bad power supply. Unfortunately
it uses a proprietary 24 pin ATX connector scenario, and the generic
power supply I have will not connect properly. The new power supply
has 24 pins, but in the wrong location.
I would like to re-wire the connector of my new supply to work with
the Compaq motherboard. Does anyone have the exact wiring changes
I would have to make to the connector to have it connect with full
functionality?
Thanks!

I doubt you might find one.

Are you certain you do not need a 24 to 20 pin adapter (the power supply should have a separate 4 pin adapter for that connects near the CPU)? I needed one when I built my last PC.

Try asking at the HP forums. Home PCs -Pavilion seems to be the one (I can't see a Presario forum).

You awoke my curiousity. This may help somewhat.

The motherboard pic is indeed the one I have, and the pin-out info.
is what I need.
Thanks!
