If you pay attention, you will find the CCC logo on the power cords of car glass and electronic equipment. This logo is 3C certification. So what is the relationship between 3C certification and computer power? It can filter out part of the cottage power supply.

3C certification on the power supply parameter nameplate
3C certification is China Compulsory Certification (China Compulsory Certification). It is a national standard implemented in my country and formulated by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) and the China National Certification and Accreditation Administration (CNCA).

Do you see it? This is a compulsory certification, that is to say, as long as the product is within the scope of 3C certification, it must be certified, otherwise it cannot be marketed.

No 3C certified power supply cottage undoubtedly

The power supply (switching power supply) used in the computer is also in the category of 3C certification, so looking at the 3C  certification on the parameter nameplate is also a way to products. If there is no 3C certification mark on the power supply, it means that the product does not even have the most basic safety guarantees, nor can it provide any protection for users and hardware. This kind of power supply is undoubtedly a fake.

Unable to cut corners inside the 3C certified power supply However, it should be noted that the 3C certification is only a basic  safety certification. With this mark, it does not mean that the quality of the product is excellent. We also need to combine evaluation and  other certifications to judge the performance of the product, and it  cannot be used as a single  criterion.

Shanzhai's 80PLUS bronze power supply
Another interesting point is that some counterfeit power supplies have imitated the fake 80 PLUS certification, but have not passed the 3C certification. Although it is difficult to check 80 PLUS, the 3C certification can expose the counterfeit goods to their feet. Isn't it interesting?
