well the formula for that is current times voltage or voltage squared over resistance. there is no direct way of measuring wattage really. it's all sort of a calculation kind of thing. but you can take a look at the charts in the basics and general info sections of this site

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
