A method and system for adjusting Digital Subscriber Line (DSL) transmitting power level are disclosed, and the method includes: acquiring a current noise margin according to a predetermined value of DSL transmitting power level; calculating a current power reduction value according to the current noise margin and a predetermined noise margin; determining an adjusted DSL transmitting power level for adjusting DSL transmitting power level according to the current power reduction value and the predetermined value of DSL transmitting power level. In the method of the present invention, the DSL transmitting power level may be farthest reduced; and the power consumed by the driver circuit may be farthest reduced; the resource waste and the heat introduced by consuming powers also may be reduced.
