The result is the total watts that your pc build requires.

If you re having trouble starting your computer you should consider checking if everything s alright with your pc s power supply. Manually calculating this requires that you multiply the total amps of all components by the total volts of all components.

Atx power supplies provide an extra 3 3v voltage rail. Most power supply models have a light on back of the unit that glows when it s powered on. They convert the 60 hertz hz or cycles per second current to a much higher frequency meaning more cycles per second this conversion enables a small lightweight transformer in the power supply to do the actual voltage step down from 110 volts or 220 in certain countries to the voltage needed by the particular computer.
