1. A power-saving supply controller circuit for supplying power based on electrical specifications, comprising:
a first switch component, wherein a first terminal of the first switch component is connected to a first terminal of a power supply device, and a second terminal of the first switch component is connected to a second terminal of the power supply device;
a capacitor, wherein a first terminal of the capacitor is connected to the first terminal of the power supply device and a first terminal of a load, and a second terminal of the capacitor is connected to a second terminal of the load;
a second switch component, wherein a first terminal of the second switch component is connected to the second terminal of the capacitor, and a second terminal of the second switch component is connected to the second terminal of the power supply device; and
a control circuit connected to a control terminal of the first switch component and a control terminal of the second switch component;
wherein, when a current is supplied from the first terminal of the power supply device, the control circuit controls operations of the first switch component and the second switch component, such that a sum of a current flowing through the first switch component to the second terminal of the power supply device and a current flowing through the capacitor, the load and the second switch component to the second terminal of the power supply device within a specified time is not smaller than a current threshold prescribed by electrical specifications.
