Power effciency helps manufacturers deliver ENERGY STAR® 4.0 compliant systems
The ENERGY STAR 4.0 specifications are recognized around the world as a way of identifying energy-efficient PCs and other office equipment. PCs that meet the ENERGY STAR 4.0 criteria are expected to become increasingly required by government agencies, corporations and consumers. Some corporations are choosing to purchase ENERGY STAR PCs as part of their “green” initiatives. The Deskstar P7K500 hard drive delivers industry-leading low-power consumption – up to 40 percent operational power savings over previous generation products – contributing to a reduction in overall system power requirements which helps PC manufacturers achieve ENERGY STAR ratings. Additionally, less power required by the hard drive means more power budget available in an ENERGY STAR PC for additional features and functions.
