Michael, you sound like a man who knows what he is talking about but I
have to
ask.........what is the model number of the Presario? I have a 7ap195 and
I
upgraded my Compaq PS to an Allied 350W last year, no problems with the
connector or functionality. I also had a 235W, at least Compaq tried to
call it
one.

I know what a pain the Presarios can be with proptietory parts and Compaq
charges a small fortune to replace or upgrade them. I'm not questioing
you, I'm
just curious.
