摘要： A circuit for controlling time sequence of a motherboard to supply power for a motherboard component includes a control circuit, a switch circuit, and a power conversion circuit. The control circuit is configured for receiving a startup signal during turning on the motherboard. The startup signal is configured to turn off the control circuit to delay a first voltage signal received by the first power receiving terminal for a period of time before outputting a new voltage signal. The switch circuit is configured for being turned off under the control of the new voltage signal. The power conversion circuit is configured for converting a second voltage signal into a supply voltage in response to the switch circuit being turned off, to provide the supply voltage to the motherboard component.
