Provided is a standby power saving circuit. A switching element is arranged between a SMPS supplying power to a load and a power supply unit supplying power to the SMPS to block power supply to SMPS in a standby mode by turning off the switching element in the standby mode and to supply power to the SMPS only when an electronic device operates. In addition, a circuit supplying a power to a load and a circuit for supplying a standby power are separated, a power storage unit for supplying a driving power to the switching element is arranged inside the circuit for supplying the standby power, and if a charged power of the power storage unit is lower than a reference value, power is supplied to only the circuit for supplying the standby power, and the power storage unit is charged. Therefore it is possible to reduce a standby power.
