80 PLUS Specification Includes |
| Internal Form Factor |
| Qualified computer units have an internal power
supply form factor and provide multiple DC voltage
outputs (i.e. 12 volts, 5 volts, 3.3 volts, etc.). |
| Energy Efficiency |
| Power supplies have a minimum efficiency of 80% when tested at each of the following three load conditions: 20%, 50% and 100% of rated power supply output.
|
| Power Factor |
| Power supplies maintain a true power factor of 0.9 or greater at 100% of rated power supply output.
|
 |
| What is 80 PLUS? |
| 80 PLUS is an innovative, electric utility-funded incentive program to integrate more energy-efficient power supplies into desktop computers and servers. The 80 PLUS performance specification requires power supplies in computers and servers to be 80% or greater energy efficient. This makes an 80 PLUS certified power supply up to 33% more efficient than current power supplies and translates to annual energy savings of approximately 85 kWh/year in desktop computers and 300 kWh/year in desktop-derived servers.

| 80plus benefits |
| Efficient Power Supplies Have Many Energy, as well as Non-Energy, Benefits |
|
80 PLUS certified power supplies are bringing utilities, the PC industry and consumers together in an exciting new energy efficiency endeavor
|
|
| Energy Benefits |
|
|
A. Energy Savings (kWh) |
|
- Efficient power supplies directly save 85 kWh per desktop PC per year, and 300 kWh per server per year.
- Upgrading to computers with 80 PLUS power supplies will reduce building cooling loads.
|
| Peak Reduction (kW) |
| 80 PLUS qualified power supplies save 16 watts on desktop PCs and 34 watts on servers during peak demand periods. |
| Improved Power Quality |
| higher power factor reduces current draw by roughly 50%, which means that up to twice as many computers can be placed on the same branchcircuit.
|
|
| B. Non-Energy Value Added Benefits |
|
| 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.
|
| Lower TCO for PC Networks |
| Increased reliability of PCs, decreased maintenance and lengthened equipment life combine with energy savings to significantly reduce the total cost of ownership (TCO) of PC networks.
