Energy savings are based on 85 kWh per year for each 80 PLUS desktop PC, 150 kWh per year for each ENERGY STAR desktop, 48 kWh for each ultra-efficient LCD monitor, 112 kWh for each Data Center Server, and 301kWh per year for each server using 80 PLUS. For PC Energy savings, the baseline is the Intel required efficiency levels for power supplies. Savings per unit for desktops is the difference between consumption between the Intel required and a minimum qualifying 80 PLUS power supply - one that is precisely 80% efficient at all load levels.

Energy cost savings are based on a national average of 9.5 cents per kWh for the commercial sector. Source: Energy Information Administration, Form EIA-826, "Monthly Electric Sales and Revenue Report with State Distributions Report." http://www.eia.doe.gov/cneaf/electricity/epm/table5_6_b.html
