A method, apparatus and computer program product are provided for implementing power system performance. Power supply system data are processed and a power path in a power supply system having a predefined component failure mode is identified for placement of a fuse. Transient and steady state current levels are determined for each identified power path. A fuse size is selected within an identified fuse size range based upon the determined transient and steady state current levels. A selected fuse energy rating is lower than an energy rating of the solid-state devices in the identified power path.
