Power requirements?

I have an old Dell Dimension PIII 750MHz computer that I just brought back
to life (several problems resolved, upgraded to XP, Etc.) The power supply
is only 200 watts and I've already added a second hard drive and a wireless
PCI network card! I need to replace the video card with one that has more
memory and better performance and I'm wondering just how far I can go with
upgrades (I still have a couple of PCI slots available), before I need to
worry about getting a bigger power supply?

Thanks all!

Does it use a standard power supply?

It's not only load but age that begins to play a part in PSU
adequacy. Ideally you would use a good 300W name-brand,
even 350W with a high-end video card (which would be a bit
of a waste of a high-end video card on a system that old,
but regardless...) . 200W PSU with only the HDD and wifi
card should be sufficient when new but higher % of capacity
wears out a PSU faster, so at this point it's not a good
long-term strategy. A new 250W would be suitable for system
as-is but with vague plans about the video card upgrade it
would be good to have more margin in a >250W PSU.
