An electronic device has a frame and a back board having plural logical units and power supply units mounted thereon. The logical units and the power supply units are alternately located on both sides of the back board in the center of the frame so that the power supply units mounted on one side of the back board may feed a power to the closest logical units mounted on the other side. Further, the air flow paths to be circulated through the logical units and the power supply units are formed so that each unit may be efficiently cooled by the air fed by an air fan unit. As a result, the feeding voltage becomes uniform and the cooling efficiency is improved.
