How much power does this computer use?

Solution
Looks like with different configurations it came with either a 305w or 255w. You can look on the sticker on the psu to see which one you have. This isn't how much power they use, psu ratings are how much they should deliver either steady or peak. Depending on their efficiency rating and component load will be how much they use.
