Abstract
A computer system including a first and second main boards, a judgment unit, a power supply, a first switch and second switch is provided. The judgment unit receives a first and second power start signals from the first and second main boards, and outputs a total power start signal. The power supply outputs a power reply signal according to the total power start signal. The first and second switches determine whether to output a power good signal individually according to the first and second power start signals. When one of the first and second power start signals is available, the total power start signal and the power reply signal are available, and the power supply outputs an operating voltage. When the first and second power start signals are unavailable, the total power start signal and the power reply signal are unavailable, and the power supply stops outputting the operating voltage.
