An embodiment of the present disclosure provides a power control circuit and a power supply device. The circuit is provided with a feedback module and a control module. A first end of the feedback module is connected to a primary side circuit of a push-pull switching power, a second end of the feedback module is connected to the control module, and the feedback module is configured to generate a corresponding feedback signal according to an electrical signal of the primary side circuit of the push-pull switching power. The control module is respectively connected to control ends of two switching tubes in the primary side circuit of the push-pull switching power, and the control module is configured to control on-off states of the two switching tubes according to a preset power voltage and the feedback signal, so as to adjust output electrical signals of power output channels.
