- 2. Efficiency Calculation Power Input 100W Output 80W Socket System = Output/ Input = 80/ 100 = 80% Efficiency
- 3. What’s the Benefit of Efficiency • ECO Friendly Efficient power supplies directly save 85 kWh per desktop PC per year, and 300 kWh per server per year. • Increased System Reliability reduced heat output increases computer system reliability by up to 40%. • Decreased System Maintenance Costs Increased reliability reduces costly repairs, IT support and lost worker productivity. • Increased Comfort Reduced heat output minimizes the need for noisy PC fans, making for a quieter and more productive office environment.
- 4. Efficiency Certificate 80PLUS The 80PLUS performance specification requires multi-output power supplies in computers and servers to be 80% or greater energy efficient at 20%, 50% and 100% of rated load with a true power factor of 0.9 or greater. This makes an 80PLUS certified power supply substantially more efficient than typical power supplies and creates a unique market differentiation opportunity for power supply and computer manufacturers.
