The 80 plus logo of plug load solutions has become an important identification method for users to purchase computer power. As an important part of the computer host, a durable power supply can ensure that it does not need to be replaced for many years, and now all kinds of high-energy computer accessories need more reliable power supply to provide protection. < / P > < p > 80 plus is based on the power efficiency as the grading unit, with a total score of 6 grades. For users, this may be easier to master than the grading conducted by high-tech certification bodies such as cybernetics. According to techpowerrup, research institutions in the industry have found that plug load solutions has significantly increased licensing fees, and power supply manufacturers may pass these fees on to consumers, especially in some models with low sales volume. < / P > < p > according to the authorization and certification policy documents of 80 plus, we can understand the cost structure of the certification, including the cost of manufacturer registration (one-time authorization fee), and the test cost of each equipment. The & quot; unit & quot; here refers to a single SKU, which will charge a fixed fee and is not applicable to each sales unit. Per SKU means that each subdivision model needs to be certified separately. For example, the HX series of the pirate ship is a model, while the hx750w and hx850w are subdivision models, which will be regarded as two separate certifications. < / P > < p > currently, plug load solutions has tripled its per SKU certification price. For new models launched after 2021, this means that the unified licensing fee will increase by tens of thousands of dollars. If a manufacturer introduces a series of 450W, 550W, 650W, 750W, 850W and 1000W power supplies with six power ratings, the certification fee for the six sub models alone will be $21000. Surprisingly, even for OEM power supply models that have passed 80 plus certification, manufacturers have to pay licensing fees. Here & quot; OEM & quot; refers to CWT, seasonal, HEC, FORTRON and other OEM power supply manufacturers. If the 650W power supply of a template model is labeled by different manufacturers, the licensing fee will be charged repeatedly because of different labels.
