Computer power is so important, so how to identify a good power supply?

The first is to look at the workmanship of the power supply circuit board. A good power supply, circuit board solder joints, and components have a large gap compared with the poor ones; good power supplies have filter devices, and poor ones do not. This is easy to see.

The second is to look at brand and quality. In addition to believing that some famous brand products such as Meji computer power supplies, the most important thing is to look at the quality of the chassis power supply. Generally speaking, the power supply with good chassis quality is not bad. In fact, it is not. The main reason is that many original high-quality power supplies are replaced by middlemen and replaced with inferior power supplies. In view of the current popular configuration, the 200W power supply is already stretched. For the safer operation of the system, it is very important to leave a margin. For users who install dual hard drives, CD-ROM, DVD-ROM, and CD-RW, choose a power supply above 250W. More appropriate. If you are financially rich, you can also consider buying a 300W power supply.
