In some implementations, a power balancing device may monitor a power supply module (PSM) that includes multiple power supply channels. The PSM may be part of a power supply system for a network component that includes multiple PSMs, with each of the multiple PSMs being associated with a maximum output power. The power balancing device may determine that at least one power supply channel, of the multiple power supply channels, is inoperable. The power balancing device may determine, based on determining that the at least one power supply channel is inoperable, a revised maximum output power for the PSM based on a maximum allowable input current to each power supply channel, of the multiple power supply channels. The power balancing device may cause the PSM to output a power that is less than or equal to the revised maximum output power.
