80 PLUS

 80PLUS certification requires a power supply to operate at a minimum of 80% efficiency. The efficiency of a computer power supply is tracked by its max value when running continuously on full load and how much power the power supply needs to push that power out.  For example, at 60% efficiency for an 800W power supply the required power needed is around 1333W which is taken from the consumer’s power factory and used by the PSU to achieve 800 Watts.  With an 80% efficient PSU it only requires 1000W from the consumer’s power factory in order to achieve that 800 Watts.  This not only is more efficient but it can also save the consumer money on their electric bills.

For a given power supply, efficiency varies depending on how much power is being delivered. Supplies are typically most efficient at between half and three quarters load, much less efficient at low load, and somewhat less efficient at maximum load.  To qualify for 80 PLUS, a power supply must achieve at least 80% efficiency at three specified loads (20%, 50% and 100% of maximum rated power.
