The present invention provides a power control device and a power control method applied to a computer system. The power control device includes a data processing unit, a throughput determining module, and a clock control unit. The data processing unit is utilized for processing and outputting data according to an adjustable clock rate. The throughput determining module is coupled to the data processing unit, and utilized for obtaining an indication value corresponding to a data output rate of the data processing unit and comparing the indication value with at least a predetermined threshold value to generate a comparing result. The clock control unit is coupled between the throughput determining module and the data processing unit, and utilized for adjusting the adjustable clock rate of the data processing unit according to the comparing result.
