请注意 :

在下面列出的是对于每个组成设备最大值的瓦数。总指标是所有设备运行峰值利用功耗的预计值。这个数值不能在通常的操作应用中体现。 然而我们感觉这一计算将使你更好的了解你的系统所需的功耗，对你应该有一定的帮助。毕竟了解和掌握一些知识不是一个坏事情：）需要注意的是显卡的功耗只是估计值：显卡厂商很少地标注设备功耗。下面只是计算主机功率，其它外围设备由于厂家标准不一，所以没有整理，提供一个大绝值：17英寸的纯平显示器大约为90瓦，17英寸的液晶显示器的大约是40瓦，音箱大约为30W，仅供参考。
Please Note: The Wattages listed below are maximum peak wattages for each component. The total amount this calculator figures is for all devices running at peak utilization. It is important to bear in mind that this amount will never be reached under typical operation. However we feel that this tool will give you a better idea of how much power your system will need. After all when it comes to power, having too large of a power supply is never a bad thing! It is important to note that power listings for some video cards are only estimates: the video card industry rarely reveal how much power their cards are drawing.
