A power source system (1) operable to supply a load circuit (10) with electrical power, including a power-supplying source (2) including a plurality of power source terminals (3) and (4) that differ in output voltage from one another, in which the power-supplying source is operable to supply the electrical power through the plurality of power source terminals (3) and (4), a power source terminal-selecting unit (5) operable to select either one of the plurality of power source terminals (3) and (4), a plurality of voltage converting units (6) and (7) connected to the power source terminal-selecting unit (5) and operable to convert electrical voltage, and a voltage converting unit-selecting unit (8) operable to select either one of the plurality of voltage converting units (6) and (7). The power source system provides the proper supply of the electrical power in accordance with a status of the load circuit (10).
