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.

Efficiency Certificate

80PLUSThe 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.
