There should be a label on the psu,specifying the total output and max current on each rail.

Ati says 300w-350w for the x800 series,but when it comes to psu`s there is no such thing as overkill.(Had a frustrating time this August trying to make my new comp run,the psu that was supposed to work with margin just wasn`t powerful enough on the 12v rail.)

A 480 should be OK, but as niu said, you can never have too much :D. Although, I suppose a 3,000,000w PSU would be pushing it...

I'd recommend you go for 550w, then you have some future-proofing. They aren't exactly the most expensive component in your computer, in fact if you don't go for anything overly fancy they're one of the cheapest, but they're definitely the most important... can't hurt to give yourself some wriggle-room.

if its a good brand it will be good, eg. shuttle xpc 250w can run a 6800gt which is more power consuming than a x800 so the brand is what matters

Just remember that power supplies differ... most will only put out a certain number of amps over each voltage rail, eg. only 18A on the 12V rail, 10A on the 5V, etc. Your graphics card, CPU, etc. all pull primarily from the 12V rail, so make sure whatever power supply you have has enough amperage available there. (to get wattage, multiply volts * amps)

I have a RX800XT Vivo Platinum, and run a HighPower 420w, and it works, though the higher the better, i hope to upgrrade to a 500w+ later on.
