A power supplier includes a power supply to provide a supplied power to the power supplier, a first capacitor charged by a predetermined voltage corresponding to supplied power supply, a power state detector to detect an on-state or an off-state of the power supply, a first controller to generate a first discharge control signal that has a signal level varying according to the state of the power supply and controls discharging of the predetermined voltage charged in the first capacitor, and a discharger connected to the first capacitor in parallel and to discharge the predetermined voltage charged in the first capacitor in response to the first discharge control signal, thereby reducing discharge risks to a user.
