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.

  1. 1. How to determine PSUs efficiency
  2. 2. Efficiency Calculation Power Input 100W Output 80W Socket System = Output/ Input = 80/ 100 = 80% Efficiency
  3. 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. 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.
