以前的计算机电源以标称功率在250瓦以下的居多,但实际上,这种电源的最大输出能力却达不到标称的额定值,一般只有不到200瓦,具体到电源的某一路输出,功率就更小了。随着CPU的频率越来越高,系统组成越来越复杂,整机的耗电量 In the past, most computers had a nominal power of less than 250 watts, but in fact, the maximum output power of such a power supply can not reach the nominal rating, and generally it is less than 200 watts. The specific output of a certain power supply , The power is even smaller. With the CPU frequency is getting higher and higher, the system becomes more and more complex, the power consumption of the whole machine
