what is the difference between c13 and c14
IEC 60320 Most desktop computers use the C14 inlet to attach the power cord to the power supply, as do many instrument amplifiers, monitors, printers and other peripherals. A power cord with a suitable power plug (for the locality where appliance is being used) on one end and a C13 connector (connecting to the appliance) on the other is commonly called an IEC cord. IEC cords are used to power many pieces of electronic equipment, including computers, instrument amplifiers, professional audio equipment and virtually all professional video equipment.
