What is the 80PLUS certification standard? Ask for explanation!

80 plus is a power conversion efficiency certification standard issued by the U.S. Energy Administration, which will evaluate the overall efficiency of a power supply based on its conversion efficiency in % and full load environments. According to the gradual improvement of power conversion efficiency, the 80 plus certification can be divided into white, bronze, silver, gold, platinum and titanium. The GX series is a gold power supply, and the LX series is a bronze power supply.

The program was first implemented in 2003 and was officially incorporated into the ENERGY STAR standard specification in 2007. To date, 80plus has become recognized as one of the most stringent power supply energy saving specifications. And the average consumer can also get the following benefits from the 80plus certification:

1.Reduce energy consumption and save electricity bills;

2.Reduces the heat generated by the computer, thereby reducing heat dissipation support;

3.Enhance the reliability of the computer and reduce the cost of computer maintenance;

80plus certification is a power certification promoted by the U.S. Department of Energy. White, bronze, silver, gold, and platinum have higher requirements for power conversion efficiency. For our users, the higher the certification, the better the workmanship and materials of the power supply, the more power saving, but the higher the power supply**.

Platinum 95%, Gold 90%, Silver 85%, Bronze 80%, White 75%.

July 2010 and June 2011. It requires that the power supply must achieve a conversion efficiency of more than 87% at 20% light load and full load, and 90% at 50% typical load. Roadmap for the implementation of the 80plus program.

The power brands and models that have passed the 80plus certification, and the 80plus official ** provide inquiry services. Up to now, a total of 1,239 power supplies have passed the 80plus certification. Among them, 830 power supplies have passed the original 80plus certification, and 318 power supplies have reached the standard of 80plus bronze certification.

There are 69 and 22 power supplies that have passed the silver and gold certifications, respectively, less than 1 10 of the total. However, with the gradual implementation of 80plus certification, there will be more and more power supplies that meet this standard. In order to obtain the best power supply quality and also contribute to environmental protection, we recommend that readers choose a power supply that has passed the 80plus certification as much as possible when purchasing a power supply.

Now the world is advocating energy conservation and environmental protection, energy conservation and environmental protection are mostly carried out from two aspects: one is to find new energy, and the other is to improve the utilization rate of existing energy to reduce the current waste of resources and the impact on the environment. In view of the current low resource utilization rate, the U.S. Energy Program has made 80PLUS certification specifications for PC power supplies to improve the conversion efficiency of power supplies and avoid unnecessary waste of resources.

Before, when we buy a power supply, most of us will weigh the weight of the power supply or look at the internal workmanship of the power supply through the heat dissipation hole, and then look at the wattage of the rated power of the power supply and whether it has obtained the 3C China compulsory certification, and now we have to see whether the power supply nameplate is marked with the 80PLUS certification standard when purchasing the power supply, because this certification is directly related to your electricity bill.

The China Compulsory Certification, which came into effect on May 1, 2002, lists PFC design as a necessary standard, which is also a consideration of energy saving. PFC is divided into two types: active PFC design and passive PFC design. Compared with passive PFC, active PFC has higher conversion efficiency, but about 30% of the power conversion is still wasted.

Therefore, many high-end power supplies and foreign power supplies now have an 80plus certification, I believe that many friends who do not pay much attention to foreign power supplies or do not pay attention to them are not very clear about the specific content of this certification. In addition, although many domestic power supplies have not obtained this certification, I believe that 80plus will be a direction for the development of domestic power supplies.

The 80plus certification standard is not immutable, with the progress of technology of major manufacturers, the efficiency of many products has been greatly improved, so the 80plus certification standard has been following the footsteps of technology to improve its own certification standards.

From July 2007 to June 2008, personal computers must meet the ENERGY STAR requirements, which means that the power supply should be at least 80% at 20% and at 50% and 100% rated output; At least the power factor at 100% of the rated output should be achieved; Maximum power requirements should also be met in standby, sleep, and idle modes.

From July 2008 to June 2009, the standard will be increased to a minimum efficiency of 85% at 50% of the rated output (82% at 20% and 100% of the rated output).

From July 2009 to June 2010, the standard will be increased to a minimum efficiency of 88% at 50% rated output (85% at 20% and 10% rated output) for PSUs.

From July 2010 to June 2011, the standard will be adjusted to a minimum efficiency of 90% at 50% of the PSU (87% at 20% and 100% rated output) for the PSU.
