Because the other parts in your computer need power also. The recommended wattage includes the other parts as well.

And the vendor wants to make sure it will work so they add on about 25% more power than what's really needed so people are not returning cards saying it did not work.

The "minimum" wattage a PC and a video card will work on are always less than the "recommended" wattage. But if you have a cheap power supply that is labeled 500 watts, it could only be putting out 300, so the video card vendor tries to account for all that stuff, including putting out a list of certified power supplies.
