A power distribution system and a method thereof regulate power distribution in a small form factor satellite flight system. The power distribution system may include a power source and a plurality of power channels. The power channels may distribute power from the power source to a plurality of systems in the small form factor satellite flight system. A processor may monitor power availability of the power source. The processor may also collect housekeeping information of the plurality of systems in the small form factor satellite flight system. The processor may regulate the power channels based on the power availability and the housekeeping information.
