An inflight entertainment (IFE) system receives power from a multiple of power supply units that each supply power to passenger seats in a multiple of multi-seat groups, wherein different power supply units supply power to adjacent passenger seats in each multi-seat group. The IFE system exhibits reduced power supply unit costs and incurs lower operational penalties in the event a power supply unit fails, and is particularly well suited for a wide body aircraft wherein flight attendant call buttons are integral with the IFE system. For example, where flight attendant call buttons are integral with the IFE system and a power supply unit fails in the present arrangement, every passenger still has access to a flight attendant call button associated with an adjacent seat, which can remove the requirement that passengers be relocated or moved to another flight in order for the aircraft to depart.
