目前电脑设备发展了太快了，越来越多的新设备出现，机箱内的300W电源也有点吃不消了，怎么办呢？再加一个300W的电源，加上去简单，那么有什么办法可以让第一个电源打开时，也打开第二个电源。/a_7x_]

?经过本人翻阅资料发现，在电源与主板连接的接口上有一个Power Supply On，可以把2个电源的这根线连接，双电源就搞定了。Bv ~"hr

??我是学电子方面的，怎么可能这么简单满足呢？深入研究，通过自己设计电路来控制，这样做出来可以让人家刮目相看了，不错，开始动工。

h-[DP5Qj9yVL [size=2]上面的这块芯片要重点介绍一下，它存放指令空间是20K，运算速度是20MHz，相当于486的速度了。

??这块电路板制作难度比较高，需要我们有耐心，还要懂的一些焊接方面的知识，当然汇编也是很重要的，这等于是自己在开发一快芯片，祝大家好运喽。

其实没这么复杂,我很简单的把两个电源并连,就得到了双电源并同时启动的效果
