Model B would be 5 watts if you want to turn on USB/Eth ports. Model A or the earlier B was 3-4 watts.
You specifically need a 1A USB port which is where a lot of people have problems. The newer one (not sure about the one with built in WiFi) was 5-10 watts which really sucks at 5 volts. Those power supplies are more difficult.
