Power MOSFET Maximum Ratings
Maximum ratings must not be exceeded in order to guarantee the lifespan and reliability of devices. For power MOSFETs, maximum ratings are defined using an absolute maximum rating system. Maximum ratings are the highest absolute values that must not be exceeded even instantaneously under any conditions.

Does the wattage on a power supply simply mean the max output wattage?
The wattage of your power supply is what it could potentially supply. However, in practice the supply won''t ever make that. I always count 60% of the capacity as the truly maximum capacity. Today however, there are also bronze, silver, gold, platinum power supplies which guarantee a certain amount (minimum of 80%) of efficiency.

Are computer power supply ratings the input or output wattage?
Nevertheless, the computer power supplies typically sold are touted as 500W, 600W, even 800W devices. This does not seem to make much sense unless these are the input wattage of the power supply. Since there is a lot of heat loss, to deliver 250W of regulated power, you might need as much as 500W inbound.

By using Ohms Law it is possible to obtain two alternative variations of the above expression for the resistor power if we know the values of only two, the voltage, the current or the resistance as follows: [ P = V x I ] Power = Volts x Amps. [ P = I2 x R ] Power = Current2 x Ohms. [ P = V2 ÷ R ] Power = Volts2 ÷ Ohms.

4 Ways to Calculate Wattage
To find out the number of kilowatts, take the number of watts divided by 1,000. Then take the number of kilowatts multiplied by your hours of usage. This is the kilowatt/hr. Then, take kilowatt/hr and multiply that number by the cost of your energy. This is your annual cost. For example, let''s say you have 10 lights.
