Any new power supply you buy will work with your existing motherboard.
Your motherboard requires a 20-pin ATX connector. Most new power supplies
have a 24-pin connector, but the 4 end pins can be disconnected or just
hang over the edge not plugged into anything.
I would caution you from installing a new motherboard in your current case,
as the ventilation probably isn't enough for a P4 processor. Your case was
designed for a Slot 1 or P3. I just wouldn't reuse the case when you
upgrade next year.
Finally, I think you should just dump the whole system and buy something
newer. It doesn't have to be brand new or state-of-the-art. A slot 1
system is just so old now. You could buy a used P3 or P4 system on
Craigslist that would have 6x the processing power for around $200.
