The power plugs in the power supply are the same, but not universal, and this is mainly a power issue, with the previous 945 main plate being almost universal with almost 300 w, but the follow-on main plate is becoming more and more functional and more power is being consumed, and in some cases 300 w power is not stable for the start-up computer host, which leads to instability in the mainframe. There are a variety of inexplicable problems, so there is a difference between the later power of 350 w and 400 w, so there is a great deal of connection between the power of the power source and the configuration of your host, especially with the main panel. In general, 350 w is the same. As long as your mainframe is not server-type, there's more to be paid for, not more than three words. One or the brand. It's like the great wall, but it's too much fake. It's hard to tell. He's got a good power supply, too

1. Beware of the authenticity of false symbols。

2. Weight: a lot of good power is important to keep it stable, so it's big, but it's aluminum alloy, it's expensive, and the fakes replace it with small, light
To see if the pcb plate welded the side of the tablet was isolated with insulation. Insulation films are used by regular plants to secure and prevent ants from accessing the power, creating short circuits, and many fake insulation films are not used to save costs, only a few glues!

4. Measuring output voltage is stable at 24v. This is more specialized, forgetting which feet to measure. You have to check it out yourself!
