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。

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.
