A computer system and a power supplying method thereof in which noise due to switched power mode is reduced for a user's convenience. The computer system comprises a mode determiner to generate a mode signal comprising a predetermined part corresponding to one among a plurality of power modes; a power supply to supply power having a level of voltage corresponding to the mode signal to a central processing unit; and a mode controller to maintain or convert the predetermined part of the mode signal corresponding to one among the plurality of power modes to lower a difference in the level of voltage when the power mode is switched from a first level of voltage to a second level of voltage, wherein the second level of voltage is higher than the first level of voltage.
