The difference between the five 80 Plus certifications available is summarized in the tables below. The numbers presented are the minimum efficiency a power supply must present under each load in order to be granted a given certification. As explained in the previous page, their numbers may be different from the numbers we see during our tests due to differences on the measuring equipment and especially on the room temperature (23º C on their tests vs. 45º - 50º C in our tests).

The requirements for each certification level depends on the market the power supply is targeted to. Non-redundant power supplies (i.e., the kind everybody uses) are tested at 115 V and use the table below.

Requirements for redundant power supplies (used on servers), however, are slightly different, as you can see in the table below. Also, they are tested at 230 V, because this is the voltage used in datacenters (datacenters use a 230 V power grid basically because power consumption is lower at 230 V and since they have hundreds of servers running, they can save money in their electricity bill).  

Besides efficiency, all 80 Plus certification levels require a power factor (PF) of at least 0.90 (0.95 for the 80 Plus Platinum certification).
