Energy efficienct power supply system

An apparatus comprising:

• a plurality of power supply units, a power monitor unit, wherein the power monitor unit is to determine a power consumption value, wherein the power consumption value represents power requirement of a power consuming system, and
• a control logic coupled to the power monitor unit and the plurality of power supply units,
• wherein the control logic is to determine power supply units of the plurality of power supply units that are to be activated to provide power to match the power requirement,
• wherein the power supply units that are identified to be activated is to operate at a maximum efficiency value while providing power specified by the power consumption value, and
• wherein the control logic is to activate the power supply units, which are identified to be activated.
