A power supply for a PDP(Plasma Display Panel) module is provided to reduce manufacturing cost by simplifying a discharge circuit in order to discharge address and sustain voltages using a diode. A sustain voltage supply unit(120) supplies a sustain voltage to a PDP module through a sustain voltage line. An address voltage supply unit(110) supplies an address voltage lower than the sustain voltage to the PDP module through an address voltage line. A discharge unit(130), which is connected to the sustain voltage line, discharges the sustain voltage based on a discharge control signal from a micom. An anode of a first diode(D1) is connected to the address voltage line and a cathode thereof is connected to the discharge unit. A cathode of a second diode(D2) is connected between the cathode of the first diode and the discharge unit. A resistance unit is series-connected between the anode of a second diode and the sustain voltage line.
