PC能耗研究
摘要：
说到节能，大多数人想到的会是非常高耗能的一些电器，却很难想到计算
机，但随着计算机的普及和家庭耗电量的不断增加，人们逐渐意识到，计算机
原来也是一个“用电大户”。目前，计算机的节能问题已经在全球范围内引起
关注，使用计算机时有何节电诀窍，也成为人们迫切需要了解的知识。
基于这样的理念，本文以节能的研究为目的，深入了解计算机的能耗，本位
的贡献如下：
1. 大致了解了计算机不同的硬件的大致能耗比例。
2. 从科学的角度分析和预测可能影响计算机CPU、显卡、硬盘、内存能耗的
因素，并对这些因素进行测算和实验，同时对已有的实验进行总结。
3. 初步分析了电源、网卡、声卡、散热装置的原理从而大致判断其能耗，由
于功耗较小，不易测算，故之作理论上的分析。
4. 基于以上的能耗的分析，对目前的计算机应用中可能存在的无用功耗进行
分析。
5. 对于不同的用户给出不同的用户需求，同时提供不同的建议使不同的人群
对计算机体验不会下降的情况下尽量节省能耗。

Abstract
When referring energy-save, most people would think of some very high
energy-consuming appliances, few think of the computer. However with
the proliferation of computers and the increasing domestic
consumption, people gradually realized that the computer was a “use
Big power”, too. At present, the computer's energy problem has
caused worldwide concern, what energy-saving tips when using a
computer, but also become an urgent need to understand knowledge.
Based on this concept, the paper studies energy conservation for the
purpose of understanding the computer's energy consumption，the
based contributions shows as follows:
1. general understand power consumption of the different proportion
of computer hardware.
2. From a scientific point of analysis and forecasts factors that may
affect the computer CPU, graphics card, hard drive, memory energy
consumption, and these factors were measured and experiments,
while for the experimental summary.
3. Preliminary analysis of the network card, sound card, the
principle of cooling devices which largely determine its energy
consumption, due to power small and difficult to measure,
so the theoretical analysis made.
4. Based on the above analysis of the energy consumption of current
computer applications, there may be unwanted power analysis.
5. Given for different users to different user needs, while
providing different proposals to make the computer experience
of different groups of people will not fall as much as save energy.
