ENERGY STAR* Capable
In 2007, the US Department of Energy and the US Environmental Protection Agency
revised the ENERGY STAR requirements. Intel worked directly with these two
governmental agencies to define the new requirements. Currently Intel Desktop
Boards are capable of meeting the new ENERGY STAR requirements depending upon
system configuration.

ENERGY STAR requirements: http://www3.intel.com/cd/channel/reseller/asmo-
