服务器电源:服务器电源有两种，一种是冗余服务器电源，一种是大功率电源。冗余服务器电源由两个PC电源组合而成，两个电源之间通过一些特殊的电路进行连接，在一个电源工作时，另一个电源处于备用状态，当工作的电源突然出现故障时，另一个备用电源能在很短的时间内接替故障电源进行工作，以防止服务器出现“宕机”现象。冗余服务器电源—般用在银行、电信等不可“宕机”的部门，普通消费者往往并不适合采用.

失真:失真分为波形失真，电压失真、电流失真等，不论是何种失真，皆以百分比来计算，其失真的大小与谐波、电压、电流以及功率因子有关系。

电磁传导干扰:从电磁安全的角度上讲电脑要符合电磁干扰标准。电磁对电网的干扰会对电子设备有不良影响也会对人体健康带来危害。国际标准化组织和世界上绝大多数国家对电磁干扰和射频干扰制定了若干标准标准要求电子设备的生产厂商对其产品的辐射和传导干扰降低到可接受程度，的是“FCC B”，它是美国对住宅环境所制定的电磁干扰标准。

Server power supply: There are two types of server power supplies, one is a redundant server power supply, the other is a high-power power supply. The redundant server power supply is composed of two PC power supplies, and the two power supplies are connected through some special circuits. When one power supply works, the other power supply is in a standby state. When the working power supply suddenly fails, the other standby power supply can take over the faulty power supply in a very short time to prevent the server from "down". Redundant server power - generally used in banks, telecommunications and other "downtime" departments, ordinary consumers are often not suitable for use.

Distortion: Distortion is divided into waveform distortion, voltage distortion, current distortion, etc., no matter what kind of distortion, it is calculated in percentage, and the size of the distortion is related to harmonics, voltage, current and power factors.

Electromagnetic conducted interference: From the point of view of electromagnetic safety, the computer must meet the electromagnetic interference standard. Electromagnetic interference with the power grid can have adverse effects on electronic equipment and human health. The International Organization for Standardization and the vast majority of countries in the world have developed a number of standards for electromagnetic interference and radio frequency interference standards requiring manufacturers of electronic equipment to reduce the radiation and conducted interference of their products to an acceptable level, "FCC B", which is the electromagnetic interference standard developed by the United States for residential environments.
