A computer system and a method for saving power thereof are provided. The computer system includes a switch, a system power supply unit and an operation control unit. The switch is electrically connected to a peripheral component selectively. The system power supply unit is electrically connected to the switch. The operation control unit is electrically connected to the switch, and it detects whether an application program relative to the peripheral component is executed. Then, the operation control unit outputs the switch control signal to the switch to determine whether the system power supply unit provides the operation power for the peripheral component.
