大多数PC均带有一个功率至少为200W的电源,这足以满足普通配置的需要。但对额外配置,PC系统电源能否满足需要,便不好一概而论。所以在为您的PC添加新设备时,先要弄清楚您的电源是否够用。 首先,应确定您的电源的最大功率,这可以从电源盒子外面的标签或系统手册中得到。将此值与您的各个设备所需功率之和相比较,各设备的功率可以参考PC手册中的技术说明或各种外设的手册。如果您知道电压和电流,可以用电压乘以电流得到功率值。如果无法得到某个设备的功率值,下面的表格可以给您提供一些参考。
Most PCs come with a power supply of at least 200W, which is sufficient for common configurations. However, the additional configuration, PC system power can meet the needs, it is not easy to generalize. So when adding a new device to your PC, first figure out if your power is good enough. First, determine the maximum power of your power supply, which can be found on the label or system manual outside the power supply box. Compare this value to the sum of the power requirements of each of your devices. For the power of each device, see the technical specifications in the PC manual or the manuals for the various peripherals. If you know the voltage and current, you can multiply the current by the voltage to get the power value. If you can not get the power of a device, the following table can give you some information.
