How can you configure a power supply to receive 220 volts AC if it is currently set for 110 volts AC?

To configure a power supply to receive 220 volts AC when it is currently set for 110 volts AC, the correct method involves adjusting a switch within the power supply itself. Many power supplies are designed with a dual-voltage switch that allows for easy switching between 110 volts and 220 volts. This switch is typically found on the back of the power supply and can be toggled to select the desired voltage.

By positioning the power switch to the 220-volt setting, the unit can safely accommodate the higher voltage input. This adjustment is crucial to ensure the power supply operates correctly without risking damage from incorrect voltage levels.

Other methods, such as changing cables or reinstalling the power supply, do not address the fundamental need to adjust the voltage setting specifically intended for the power supply’s operation. Turning off and unplugging the computer is a necessary safety measure when working with electronic equipment, but it does not solve the issue of changing the voltage setting.
