Abstract:
1. A method for adjusting power consumption, the method being adapted for a device for adjusting power consumption of an external graphic processing unit according to different voltage sources and comprising: determining whether power to the external graphic processing unit is supplied by a first voltage source or a second voltage source of the voltage sources according to a comparison result of an input voltage input to the external graphic processing unit and a default reference voltage, wherein the power to the external graphic processing unit is determined to be supplied by the first voltage source if the input voltage is higher than or equal to the default reference voltage, and the power to the external graphic processing unit is determined to be supplied by the second voltage source if the input voltage is lower than the default reference voltage; wherein the second voltage source is a computer apparatus, and the external graphic processing unit is externally connected to the computer apparatus through the device for adjusting power consumption of the external graphic processing unit, the external graphic processing unit being controlled to remain in a normal speed operation status when the power to the external graphic processing unit is determined to be supplied by the first voltage source; and the external graphic processing unit being controlled to remain in or convert to a low speed operation status when the power to the external graphic processing unit is determined to be supplied by the second voltage source.
