An adaptive power managing device for an IC chip or a circuit system comprises a tunable voltage generator, a data generator, a data processing unit, a data checking unit and a control unit; the tunable voltage generator is used for providing the IC chip or the circuit system with an operating voltage; the data generator is used for generating a series of predetermined data to the data processing unit; the data processing unit is used for processing the series of predetermined data and then outputting a series of output data associated with the series of predetermined data; and the data checking unit is used for checking the validity of the series of output data; wherein if the series of output data is checked to be invalid, the control unit outputs a control signal for tuning up the operating voltage; if the series of output data is checked to be valid, the operating voltage is maintained or the control unit outputs another control signal for tuning down the operating voltage whereby efficiently achieving the objective of power management. The present invention also provides an adaptive power managing method.
