超级用户读者Sam Hoice有一些PSU问题：
My computer powered off the other day on its own, and now when I push the power button, nothing happens. My assumption would naturally be that the power supply is done (possibly well done) but is there any good way to test this before I buy a new one?
前几天我的计算机自动关闭电源，现在当我按电源按钮时，什么也没发生。 我的假设自然是电源已经做好了(可能做得很好)，但是在我购买新电源之前，是否有任何好的方法可以进行测试？
How can Sam test things without damaging his current computer or other hardware?

超级用户贡献者Grant写道：
Unplug the power supply from any of the components inside the computer (or just remove it from the computer completely).
从计算机内部的任何组件上拔下电源(或将其完全从计算机上卸下)。
USE CAUTION HERE (Though you’d only be shocked with a max of 24 volts)
请在此处使用注意事项(尽管最大24伏特只会使您感到震惊)
- Plug the power supply into the wall. 将电源插入墙壁。
- Find the big 24-ish pin connector that connects to the motherboard. 找到连接到主板的24针大销钉连接器。
- Connect the GREEN wire with the adjacent BLACK wire. 将绿色线与相邻的黑色线连接。
- The power supply’s fan should start up. If it doesn’t then it’s dead. 电源的风扇应启动。 如果没有，那就死定了。
- If the fan starts up, then it could be the motherboard that’s dead. You can use a multimeter to check if there is power output from the power supply. 如果风扇启动，则可能是主板坏了。 您可以使用万用表检查电源是否有电源输出。
Adrien offers a solution for readers who may not be comfortable jamming wires into their power supply unit’s MOBO connector:
Adrien为可能不习惯将电线插入电源设备的MOBO连接器中的读者提供解决方案：
Most well-stocked geek-stores sell a “power-supply tester” that has all the appropriate connectors to plug each part of your PSU into, with spiffy LEDs indicating status of the various rails, connectors for IDE/SATA/floppy power cables, etc. They run ~$20 US.
大多数库存充足的怪胎商店都出售“电源测试仪”，该电源具有用于将PSU的每个部分插入的所有适当的连接器，带有指示各个导轨状态的漂亮的LED，用于IDE / SATA /软盘电源电缆的连接器，等等。它们的价格约为20美元。
With a little careful shopping you can even find a highly-rated PSU tester for a measly $6.
稍加购物，您甚至可以以仅$ 6的价格找到一款高评价的PSU测试仪。
