PURPOSE: An apparatus for supplying power in a base station transceiver subsystem is provided to prevent waste of installation space in a power distribution rack or a rectifier since each rack requires at least two power supply branches, and reduce the cost since a plurality of racks share one or more branches. CONSTITUTION: A power distribution rack(510) distributes direct current provided from a rectifier into a plurality of branches by using a plurality of fuses(511) and a plurality of diodes(513). A plurality of base station controller racks(520-540) are directly connected to the power distribution rack(510), forming a daisy chain form with each other, and receive power from at least one branch. At least, one power terminal(527) of the first base station controller rack(520) directly connected to the power distribution rack(510), distributes power supplied from at least one branch, so that one part of distributed power is provided to the first base station controller rack(520) and the other part of distributed power is provided to the next base station controller rack. At least, one power terminal of at least one second base station controller rack connected to a front end base station controller rack, distributes power supplied from a power terminal of the front end base station controller rack, so that one part of distributed power is provided to the second base station controller rack and the other part of distributed power is provided to the next base station controller rack.
