A power management subsystem included in a computer system may include a host device and a power circuit group. The power circuit group includes multiple power circuits arranged in a tree-like structure. The resources of the multiple power circuits are mapped to corresponding addresses within a common address space. The host device sends, via a first communication bus, commands to a branch power circuit of the multiple power circuits, which, in turn, relays the commands, using a second communication bus, to corresponding ones of the other power circuits based on respective power resources specified in the commands received from the host device.
