Power Supply Upgrade? vs. Graphic Card Power

OK... I should be able to answer this myself, but I'm having a heck of a time deciphering Compaq's system specs. Here's the deal. I have an older machine (Compaq Deskpro PIII EN 733Mhz) which is all I can really afford right now, that I'm trying to keep alive. For various reasons, I need to upgrade my Geforce 2Ti video card, but all the cards I can find specs for seem to require 250 Watt power supplies or better to run. Mine's a 200 Watt that came with the machine.

My questions are as follows:

1) Can anybody help me figure out if it's possible to stick a more powerful PS into this old beast? And b) if so, what recommendations do you have as to brands, size, etc.

2) Are there any current or recent generation Video Cards out there that I can dig up to replace my current Geforce 2Ti with something a little more recent/capable in the graphics dept.? If it makes any difference, I'm leaning towards cards with a Heatsink rather than a fan, as the fan on the Ti is dying a hideous death right now, causing my most recent dilemna. I figure a case fan and a non-fan-cooled video card are the way to go.

Any help y'all can offer would be MOST appreciated! Thanks!
