Gold medal, silver medal, and bronze medal refer to the conversion efficiency of the power supply. There are titanium, platinum, gold, silver, bronze, white and other grades. The higher the grade, the higher the conversion efficiency, but the higher the cost, the smaller the power, and the higher the relative cost.

Of course a gold medal is good. This refers to the conversion efficiency of the power supply. Conversion from alternating current to direct current. There is a concept of PFC. If the PFC is active, the conversion efficiency will be high and power will be saved. If it is passive, it will be very low. When choosing, try to choose an active power supply that is better and will be selected under the 80PLUS trademark. Refers to efficiency above 80%.

If it is passive, it will be very low. When choosing, try to choose an active power supply that is better and will be selected under the 80PLUS trademark. Refers to efficiency above 80%. Bronze, Silver, and Gold medals are more than 80% stronger in power.

This is an 80plus certification standard. Ordinary consumers can also get the following benefits from the 80Plus certification: reduce energy consumption and save electricity bills; reduce the heat generated by the computer, thereby reducing heat dissipation support; enhance the reliability of the computer to reduce computer repair and maintenance costs; Bronze certification will be implemented from July 2008 to June 2009.
