摘要： A management circuit for a power supply is provided. The power supply includes a power factor correction circuit and a power conversion circuit. An output of the power factor correction circuit is coupled to an input of the power conversion circuit. The management circuit includes a power factor correction controller, a pulse width modulation controller and a control circuit. The power factor correction controller controls power factor correction of the power factor correction circuit. The pulse width modulation controller controls power conversion of the power conversion circuit. The control circuit selectively activates the pulse width modulation controller according to a first activated signal generated by an input power of the power supply. After the pulse width modulation controller is activated, the control circuit generates a second activated signal based on the first activated signal. The control circuit activates the power factor conversion controller according to the second activated signal.

摘要： A casing including a first body and a locking plate is provided, the locking plate is installed to the first body, and the locking plate extends inward to form a frame, so as to lock the casing to a main chassis of a desktop computer. Compared with the existing technique, the casing is directly locked to the main chassis of the desktop computer from exterior to interior through the locking plate, i.e. the casing is adapted to install the redundant power supply without changing an internal configuration of the main chassis or changing an outline dimension of the main chassis or the casing. Moreover, in terms of material purchase, it is unnecessary to purchase casings of other dimensions, but only one type of casings are used to produce general power supplies and redundant power supplies, so as to effectively save the manufacturing cost. Moreover, a redundant power supply is provided.
