【 Weak current College 】 briefly computer power and electricity consumption

Now many users have noticed that the power in the whole of the importance of computer configurations, purchase the computer normally require a reliable power supply. But how much power the power to meet the needs of the computer, as well as the usual computer use much electricity and electricity, but very few people go to calculate a figure; this article provides some general data for your reference.

Computer parts power overview

The various parts of the computer requires a power-driven, so the parts that have the corresponding power consumption, the electric energy consumption rate we usually call it power or power.

With the continuous development of computer hardware, hardware capacity consumption are increasing, so the power requirements are higher and higher.

Power consumption compared to large equipment: monitor, CPU, video card and the motherboard the transistor-highly integrated parts. Of these, Intel and AMD's flagship processor and graphics of top-level products have exceeded 90W (Watts) of power, or even already broke the 100W control; such as: NVIDIA6800Ultra power have reached 120W external power supply required; ATiX850XTPE interface. For the video card, the higher the frequency of core, graphics memory and memory capacity, are causing power upgrade. For the CPU, the same manufacturing process CPU frequency higher consumes more; improve voltage overclocking also will increase the CPU power consumption.

Learn ways to power accessories

Schedule the power data is approximate and is not an exact numeric value; and the user's computer configuration also between. If you want to understand exactly how your computer's power in various parts, in addition to the specification by viewing accessories and search the Internet, you can test the software such as EVEREST for reconnaissance.

Analysis of how much power the computer

When we know the computer power of all parts in General, you can accumulate and then calculate a PC consumes power. The accessories listed below: IntelPentium42.0GHz i865PE motherboard, processor, video card, NVIDIAGeForceFX5200Ultra 256MBDDR memory, hard drive, DVD-ROM drives 7200PRM, RW, coupled with a sound card, network card, mouse and keyboard, and a host of power consumption by approximately $ 250W (if coupled with a 17 inch CRT monitor, 320W or so); now mainstream 300W power supply is in line with demand, even if additional TV card or connect a few USB, IEEE1394 interface's parts, but also the rich more than the rich.

In addition, we know that 1 unit is 1 kW/h, if a computer's total electricity consumption, 320W per unit $ 0.8 8 hours a day on, day in the electricity consumption of the computer's is about $ 2. Of course, here in consumption, is the theoretical data, but also about computing, can only be used as a reference. As for the actual, need to post, using CoolerMasterRealPower power supply, Multimeter, and other special tools test to get an accurate value.

Finally, it is recommended that you purchase power or upgrade a computer to calculate the computer power consumption by the individual parts, ensuring the provision of adequate power supply. After determining the power, then according to their own computer to the actual configuration; purchase price constraints, we do not have to be blind pursuit of Bove high-power power because, after all, for your own is the best.
