Apart from the ecological considerations, can say that there is little reason "urgent" to reduce the consumption of its PC: it's a totally optional and voluntary approach. Consumption in the rest of average desktop varies between 45 and 60 watts once it is built around an integrated graphical circuit and mid-range components. Add an a nothing more powerful graphics card and a little more strong material and you will easily reach 80 watts. Down to 50 watts seems perfectly acceptable for a modern computer without large graphics. But when it reflects well, why would it not reduce the consumption of his PC if it costs nothing and hinder neither performance nor functionality?
Contrary to what one might believe, the main interest of a PC consumes 25 watts at rest rather than fifty is not financial: at this level of consumption, the savings are relatively small, especially given the price of electricity in France. No, benefits stories are mainly of annex order and the most important is without any doubt to the level of the necessary cooling. A system using only 25 watts at rest requires less fast than a normal configuration fans. Result is a reduction in power consumption, but also the noise. With such consumption, it is even possible to consider a computer cooled passively, although in this case make a most important original investment.
The PC to 25 watts at rest
New processors with dual-core Intel Core i3 and i5 and H55/H57 chipset today allow us to design a system fully functional, extremely efficient and consumes only 25 watts at rest. In fact, it is even possible to descend lower still for some settings (low voltage) or a choice of components. Incredible when you know that performance does not suffer! Obviously, speed is not of a quad-core with a high range graphics card, but all similarly: performance are those of a dual-core, the features are excellent, all obtained with midrange components.
