Replacing Compaq Power Supply!

Hey guys I had purchased a new 500watt power supply and was wanting to
put it in my new case... but ran into a problem... connected the new
psu to my compaq motherboard and nothing happened... it would though
when I used the compaq psu. Well I have discovered that compaq uses a
different standard than what the 24pin on my new psu is using... I
don't know anything about re-wiring or what would be needed to do to do
that.... but I suppose that is an option... is there any kind of
adapter I could buy ? I know on several forums people have asked but
nobody has responded with a yes or no... I really need to get my psu
running x.x the compaq psu I have won't hold up with all the components
I have.... and I don't have the money to replace the motherboard just
yet....

Which model of Compaq computer is this? It is impossible to respond to you
without very specific information... Ben Myers

Compaq Presario 5415WM

Power supply is an Aspire 500W ATX Power Supply model # ATX-AS500W

both psu's are 24 pin, but I saw that compaq's pins are different than
the standard ATX....

I'm surprised that Compaq used a 24-pin power supply in the Presario 5415WM.
But then I should never be surprised at any product the HPaq produces. The
Presario 5415WM is old enough that it pre-dates the newer BTX 24-pin standard.
I'll bet that the pinout of its power supply is identical to some of the earlier
Compaq DeskPro desktop models, which used a 24-pin power arrangement.

24-pin is the BTX standard. 20-pin is the ATX standard. ATX-12v adds the
supplementary 12v connector required by newer Socket 478 Pentium 4 and AMD
CPUs... Ben Myers
