摘要： A power supply apparatus and display apparatus having the same are provided for outputting power, in which a standby mode selecting unit switches on and off a standby mode, a standby power supplying unit outputs standby power of a predetermined magnitude in the standby mode and temporarily outputs first auxiliary power when the standby mode is released by selecting of the standby mode selecting unit, a main power supplying unit outputs main power of a predetermined magnitude, and a backup power supplying unit continues to supply second auxiliary power, which is induced by the main power output from the main power supplying unit, to the main power supplying unit as driving power substituting the first auxiliary power. Thus, the output of standby power is increased when a standby mode is released, without increasing power consumption in the standby mode, using a standby power converter with small capacity.
