Abstract: A power supply apparatus is provided, in which a control chip is used to detect an AC input power, so that it is unnecessary to additionally set an external independent detection circuit, by which not only a design cost is decreased, an extra standby loss is also avoided. Moreover, the method of using the control chip to execute detection of the AC input power can effectively decrease detection deviation, so as to notify the load system within an allowable (accurate) time (i.e. the predetermined time). Moreover, the control chip can determine and adjust the predetermined time within which the indication signal is generated to notify the load system according to an application requirement of the load system, so that the power supply apparatus can be generally applied in different types of the load systems having a timing control requirement.
