Abstract: An overclocking control method cooperates with an overclocking application of a computer system when the overclocking application is started. The overclocking control method includes the steps as follows. A BIOS enters an overclocking mode according to an executing state of the overclocking application. The BIOS receives a first triggering signal outputted from a south bridge chip, and the first triggering signal is generated by the south bridge chip according to a first button of the computer system. The BIOS selects a piece of corresponding overclocking information from a look-up table and loads the overclocking information into a register of the BIOS according to the first triggering signal to control the overclocking of the computer system.

Abstract: A power management apparatus and a system using the same, which are suitable for managing power supplies for peripheral devices connected to a host system, are provided. The power management apparatus includes power supply switches, a control circuit and a power supply unit. The power supply switches are respectively coupled between the peripheral devices and the power supply unit. The control circuit determines whether or not operating powers are supplied to the corresponding peripheral devices through the power supply switches according to a control signal outputted from the host system.
