    Abstract: An uninterruptible power supply (UPS) device for providing a DC operating power to operate a motherboard is disclosed. The UPS device includes a main power supply system, a backup power supply system and a disable control unit. In a normal condition, the main power supply system converts and outputs a first DC standby power to the motherboard. The backup power supply system outputs a second DC standby power to the motherboard when the main power supply system is incapable of normally outputting the first DC standby power. The disable control unit receives a power supply-off signal outputted by the motherboard in a power-off state to generate a disable signal to the backup power supply system. In response to the disable signal, the backup power supply system stops outputting the second DC standby power to the motherboard.
