A high-voltage detecting circuit for saving power in a standby mode is provided. The high-voltage detecting circuit includes a high-voltage detecting module, a switch module and a control module. The high-voltage detecting module is composed of several resistors for detecting a high-voltage power supply. A control terminal of the control module is controlled by the power supply to switch off the switch module when the power supply stays at the standby mode, ensuring that the power loss of the high-voltage detecting module is eliminated.
