Tricks on Building a Green PC

The consumption of energy is something that we are still concerned about the modern world. Personal computers should not be ignored with regard to the amount of energy, day after day. A typical modern PC can consume about 100W to 150W in use to a minimum and almost heavy. Rates for high performance gaming platform can be doubled.

If your computer has been left all day, these figures may represent a substantial portion of the electricity bill, especially if you have an office full of computers.

When building your own computer (s), you can take steps to make the machine more efficient. It is also noted that for his PC green you really have to take into account the amount of lead in computer parts. Lead solder is in place electronic components on a circuit. The components containing low levels of lead and other dangerous items have been baptized as "RoHS" compliant.

There are three main factors of energy consumption of a PC.

Power Supply (PSU)

The PSU would be ideal 100% efficient, ie the power that the consumer is equal to the power it delivers to the computer. It is obviously impossible and some power is converted into heat and noise, but modern PSUs are often greater than 80% efficiency.

PSU should be able to provide power when needed, rather than sit at a computer burning electricity when the power is not needed.

You can choose to secure the supply, which is higher than 80% more efficient, make sure that it is a "80 Plus" certification. It also ensures that power is lead free and RoHS-compliant.

Processor Unit (CPU)

Number of available processors, which are designated as "green." They are usually slightly more expensive than their non-green, and even slower, but the performance difference is not huge. If you do not want to buy green, then stick with dual-core processors, and check the specifications for power, especially to a minimum.

Of course, no need to install a standard computer processor. You can actually use a laptop processor, but it could be hunting around for a supplier. These processors are low power and the number of energy-saving features, such as green, but processors are slightly more expensive.


If you have an old CRT monitor, but much loved, you will use the PC's new green building, think again. This type of monitor you are hungry monsters that now drawing to a close. Modern LCD panels are more green, a lot of energy, and actually offer a better viewing experience to offer, you can choose the right type of panel.

Not much said about the details of Crowley's energy reduction venture. This is an ad for the man, not his business. Not to say he is not an interesting guy. But the good news he brings to an energy-strapped globe might just be what we need to make us more conscious about saving the environment.

define physics


(Physics / General Physics) the branch of science concerned with the properties of matter and energy and the relationships between them. It is based on mathematics and traditionally includes mechanics, optics, electricity and magnetism, acoustics, and heat. Modern physics, based on quantum theory, includes atomic, nuclear, particle, and solid-state studies. It can also embrace applied fields such as geophysics and meteorology.
