A system for performing computing operations in a data center includes one or more sets of computer systems, one or more primary power systems, and a reserve power system. The primary power systems include a downstream portion that supplies power to at least one of the sets of computer systems. The reserve power system includes switches that switch between supplying a primary power feed and a reserve power feed from the reserve power system through part of the primary power system. An input resiliency switch can switch between supplying primary power or reserve power to support power supplied to the sets of computer systems through the primary power system based upon a primary power feed fault. A power distribution switch can switch between supplying primary power and reserve power to part of the downstream portion of the primary power system to bypass an upstream portion of the primary power system.
