How much do you know about computer power consumption

How much electricity does your computer consume every day? Do you know that? Many people have thought about it, but have not counted it. Generally, the power consumption of the television is below 80W, the computer is approximately between 250--400w. One computer per month power consumption: If 300Wx a day for 10 hours x One months 30 days =90kw, that is, 90 degrees of electricity, this is only a conservative estimate (monitor consumption: 15 inches, 17 inches, 19-inch monitors are consumed in 60W, 80W, 100W, respectively).

A report by a Canadian university suggests that the latest computer, if it has power-saving function, consumes about 35W per hour, is about a little higher than a general brightness bulb, although this waste has little impact on individuals, but if all the computers in the world are on standby for a long time, the amount of electricity wasted per hour is staggering.

The computer also has energy consumption in the sleep state, about 7.5W, it's hard to understand that when you go to standby under Windows XP, power consumption is up to 51.48w!. The motherboard at this time to protect the data, but also in the consumption of electricity; even if the machine is turned off, as long as the plug has not been pulled, the computer still has energy, about 4.81w! such as remote control and intelligent switch to make the appliance more comfortable, but also to the electrical added an additional energy-standby energy consumption.

In standby state, the device does not cut off the power, and does not run the main function, looks like a shutdown, in fact, there are a few parts of the electrical wiring and components in the live work, this state of electricity consumption is standby energy.

Even in the shutdown state, is also an electric mouse, in the constant stealing electricity. Standby loss is usually referred to as our most common situation----shutdown after the power supply to connect the motherboard, monitors, printers, ADSL network terminals, routers, etc., at this time +5VSB also to continue for the motherboard, keyboard, mouse and other equipment continues to power, at this time its standby power consumption will also be around 5W. Click the system shutdown, computer host, monitor and its computer peripherals (printers, scanners, ADSL network terminals, routers, etc.) are still in power consumption.

Computer Standby Power Test: (with multimeter model for Mastech?) MS8215)

Condition: When the computer does not boot

Test equipment for computer mainframe, 17″ flat-screen display

Result: The power instantaneous consumes 176 watts

2 seconds to continue standby power consumption of 13.7 watts

Computer in the shutdown state, there is no real harm to disconnect the power:

Computer Standby State In addition to power consumption, resulting in unnecessary energy waste;

Long-time electricity will make the electrical appliances in a state of fever, thereby shortening the life of electrical appliances;

In the event of natural disasters, such as: Thunder Thunder will be along the wire (or cable) to hit the electrical appliances.

Here are some energy-saving suggestions and measures

1, suspend the use of computers, if the expected pause time is less than 1 hours, it is recommended to put the computer on standby, if the pause time is greater than 1 hours, it is best to shut down completely.

2, usually after the computer to normal shutdown, should unplug the power plug or power off the switch on the wiring board, and gradually develop the habit of complete power off, and do not let it in the power state.

3, the use of peripherals such as printers, speakers and so on in time to turn off. (Speaker is a large power consumption)

4, such as optical drive, floppy disk, network card, sound card, such as temporary use of equipment can be in the BIOS screen out. (Power consumption will not fall too much, long time to extend the service life of the equipment)

5, the use of CPU cooling software.

6, reduce the brightness of the display. In doing text editing, the background darkened some, energy-saving while also protecting eyesight, reduce the fatigue strength of the eyes. When the computer plays music, storytelling, novels and other single audio files, you can completely turn off the monitor.

7, many DIY enthusiasts are keen on overclocking. As a technical test is not necessary, if not overclocking as can fully meet the performance needs, or as little overclocking, energy-saving and stable and safe.
