A DC uninterruptible power supply (DC UPS) is configured in a computer device that includes a power supply connected to an AC power source and a motherboard. The DC UPS is electrically connected between the power supply and the motherboard. Thus, when the power provided by the power supply is abnormal, the DC UPS can provide a set of DC powers to the motherboard and associated devices in the computer device.
