How to calculate the wattage of a power supply?
Determine amps or volts the same way. You can do the multiplication formula in reverse. For example, let’s say you have an AC 24-40 power supply. This means your power supply has 24 volts and 40 watts. The power source can supply 1.6 amps. The formula used is 40-? X 24. Thus, you would divide 40 by 24 to get 1.6.
