A quote from the article:
Although PCs have steadily grown more energy efficient over the last few years, there's still room for improvement. We tried to find out how you can make a Haswell system as efficient as possible. We first tried using different components, then attempted tweaking various (BIOS) settings, and finally tried undervolting.Workshop: making your PC as energy efficient as possible @ Hardware.Info
Generation after generation, processors (especially Intel's) have become more energy efficient. Nevertheless, a desktop computer will still consume tens to hundreds of watts under load, depending on its configuration. Those who choose more efficient components for their PC and/or make the right adjustments in the BIOS, can substantially reduce their PC's power consumption. Those who don't mind a small drop in performance can achieve even greater reductions. Read on to learn how you can do this!
