Dear ENERGY STAR Computers Partner or Other Interested Stakeholder,With this letter, the U.S. Environmental Protection Agency (EPA) is releasing the Draft 2, Version 7.0
ENERGY STAR Computer specification. EPA thanks stakeholders for the feedback that they provided
and has taken that feedback into consideration in developing this draft specification.
The Draft 2, Version 7.0 specification incorporates the following key elements:
Definitions:
EPA is proposing a new definition for mobile workstation, and has revised definitions for workstations,portable all-in-one computers, discrete graphics, and additional internal storage.
Energy Criteria:
EPA has adjusted the notebook base allowances and performance score boundaries for notebooks in thisDraft 2. Due to a mistake noted by stakeholders in the analysis, the revised specification levels result inoverall requirements that are more stringent than those found in Draft 1 and identify the top quartile of themarket for each of the three product categories. EPA has harmonized more closely with the CEC discrete
graphics and integrated display adders. EPA has also clarified that products that claim the Energy
Efficient Ethernet (EEE) allowance must have EEE enabled at shipment.
Amendments to Scope:
EPA is proposing to remove the newly defined mobile workstations from the scope of Version 7.0. This
product category may be reconsidered as part of the Version 8.0 specification revision if further data
regarding this market is made available.
Power Supply Criteria:
EPA is proposing to maintain the 80Plus Gold equivalent internal power supply (IPS) requirements
proposed in Draft 1 but only for products that ship with IPSs with a nameplate rating greater than 500watts. EPA also corrected the power factor requirements at 50% load to align with the 80Plus website.
Full Network Connectivity:
EPA has clarified that increasing the flexibility of very low power network connected modes to apply thefull capability network proxy mode weighting does not negatively impact products that do not make use of
these modes, as they will continue to certify using conventional mode weightings as the vast majority of
products have in Version 6.0/6.1.
