An integrated power supply apparatus for information appliances includes a power supply input unit, a rectification unit and a voltage boosting unit. The previous design of transforming low voltage to high voltage through a voltage boosting unit (inverter) is changed to transforming to medium voltage through the rectification unit then is transformed to high voltage through the voltage boosting unit. Therefore loss on the low voltage power supply is eliminated, and performance may increase from 64% to about 80% or more. Thus the low voltage power supply module that otherwise should have extra power and greater watts may be shrunk and power supply efficiency may increase.
