1. A server chassis, including:
a server motherboard;
a power supply unit (PSU) positioned within a first enclosure of the server chassis, the PSU including:
a control board coupled to the server motherboard;
a hot-pluggable rectifier;
a charge control management module coupled to the control board;
a first capacitor coupled to the hot-pluggable rectifier;
a first voltage regulator coupled to the first capacitor and the hot-pluggable rectifier; and
a battery pack positioned within a second enclosure of the server chassis, the battery pack coupled to the charge control management module;
wherein, when the hot-pluggable rectifier is coupled to the control board and an AC source is coupled to the hot-pluggable rectifier, i) the hot-pluggable rectifier maintains a first voltage on the first capacitor, the first voltage on the first capacitor is input to the first voltage regulator, and the first voltage regulator provides power to the server motherboard through the control board and ii) stores energy, via the charge control management module, at the battery pack,
wherein, when the hot-pluggable rectifier is de-coupled from the control board and/or the AC source is de-coupled from the hot-pluggable rectifier, the battery pack provides power to the server motherboard via the charge control management module.
