Hi and welcome to Geeks to Go. I have an old HP Pavilion as well, and I have had to remove the power supply several times to install new components, upgrades etc. I do recall that it is smaller than the usual atx power supply in my other computers. No doubt you are trying to find one of similar size because like my HP, that case is really packed tight and there is no way an atx power supply will fit. My first suggestion would be to go to hp's web page and use their web interface to ask their technical support for specs on that power supply. My own experience using that is that they do in fact answer and it does not cost you anything, unlike calling them. I wanted to know the maximum cpu upgrade that I could to to my old 450 Mhz HP, so I asked my question and provided them with the data on the HP build sticker on the back of the computer. I would suggest you include that data in your question.
Your other option would be to examine the power supply, get all of the specs off of the unit, measure the dementions and then start searching the web for a replacement. I would start with HP.
