Overall efficiency compared to “EPA rev. 5.0 computers”
This latest ENERGY STAR
method of testing the energy performance of computers. It sets a limitation on typical energy
consumption (TEC) of computers which is a value for typical annual electricity use, by
measurements of average operational mode power levels scaled by an assumed typical
usage model (duty cycle). This new approach, like the previous one, does not establish
direct limits to the power supply minimum efficiency for each different state. In fact it
depends on the actual load applied by computer itself. At the moment this application note
has been written, not all the major computer manufacturers have produced specific
requirements for EPA rev. 5.0 compliant designs. Anyway, the good margin achieved against
the EPA rev. 4.0 limits proves that this board can be a viable solution even for upcoming EPA
5 computer designs.
