How to look at the power of computer

Generally look at the power supply power We all say is rated power, so everyone in the purchase of power must pay attention to look at the rated power, not the maximum power. Many well-known fake brand power supply, are like in the Power label won a very high power value, but this is only the most high-power, not rated power, to know that the maximum power is the limit of the power supply, the power supply under the limit of the operating life is not long. Therefore, I suggest that you try to choose Brand Power, the general brand Power will clearly indicate the rated power, the following we said power supply power is also referred to the rated power.

First, let's take a look at the more representative Intel Classic Getting Started configuration: G630 processor +h61 motherboard +hd6750 graphics +1TB hard disk +4GB memory, overall power consumption of about 170W, for a classic introduction to the unique configuration, all DIY accessories add up rated power only 170W, plus the mouse , keyboard to die will not exceed 180W, plus about 50W online reservation, for the introduction of a single display configuration, in fact, the power of 250W is enough, the following figure:

From the results of actual test data, we can see that in fact, the initial configuration of the power is indeed very low, even in the platform alone, the power is less than 200W, if not with the single show, the Power can also be reduced by dozens of Watts, so in some SNB or APU entry configuration in fact, the rated power of 200W has been completely enough, So for getting started configuration (including show alone) in fact 200w-300w about enough.

Below we will be the classic Intel midrange Computer Configuration: H61 motherboard +i3 2120 processor +gtx460 video card +1TB hard disk +4GB memory configuration For example, describes its rated power about how much.

As shown above, in the current mainstream installed in the most popular H61 motherboard +i3 2120 processor +gtx460 graphics +1TB hard disk +4GB memory computer, its rated power is only about 240W, plus 50W reserved on line, in fact, the ideal rated power in 300W or so can meet the requirements, In addition, we tested the mainstream AMD platform configuration, such as: Speed Dragon II 6,404 core +880g motherboard +hd6770 graphics +1TB hard disk +4GB memory its rated power is about 245W, the best 300W or so to meet demand.
