Understanding the 80 Plus Certification

Everything you need to know about the 80 Plus certification, their methodology, and the different certification levels (Standard, Bronze, Silver, Gold, Platinum, and Titanium). Updated to include the 80 Plus Titanium certification.

The Available Certifications

  • 2. The 80 Plus Certification Methodology
  • 3. The Available Certifications

The difference between the six 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 (23° C on their tests vs. 45° – 50° 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. The Titanium certification is the only one that has a minimum requirement for 10% load.

115 V Non-Redundant 10% Load (Ultra Light) 20% Load (Light) 50% Load (Typical) 100% Load (Full) Power Factor
80 Plus Standard NA 80% 80% 80% 0.90 at 50%
80 Plus Bronze NA 82% 85% 82% 0.90 at 50%
80 Plus Silver NA 85% 88% 85% 0.90 at 50%
80 Plus Gold NA 87% 90% 87% 0.90 at 50%
80 Plus Platinum NA 90% 92% 89% 0.95 at 50%
80 Plus Titanium 90% 92% 94% 90% 0.95 at 20%

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).

230 V Redundant 10% Load (Ultra Light) 20% Load (Light) 50% Load (Typical) 100% Load (Full) Power Factor
80 Plus Standard NA NA NA NA 0.90 at 50%
80 Plus Bronze NA 81% 85% 81% 0.90 at 50%
80 Plus Silver NA 85% 89% 85% 0.90 at 50%
80 Plus Gold NA 88% 92% 88% 0.90 at 50%
80 Plus Platinum NA 90% 94% 91% 0.95 at 50%
80 Plus Titanium 90% 94% 96% 91% 0.95 at 20%
