How much power does the computer configure?
DIY installed computer power supply how much to fit? Generally look at the power supply, we are talking about the rated power, so when we buy power, we must pay attention to the rated power, rather than the maximum power.
Power don't save money. Many cottage power labels 300W, 400W or even higher, only a few dozen dollars, in fact, even the brand 200W is not as good. Power supply is the most important guarantee for the stability and life of a computer. Power key to see its structure, workmanship, materials, power enough.You this configuration can be rated 300W, do not want to spend money on diamond Huntkey cold Win7200 yuan.CPU Athlon 630 to 615 low, too much feeling is not normal, do not know whether the three nuclear open... Taobao's cheapest bulk is about 640Motherboard with MSI bar, 760GM-E51 is about 490, on the only obvious words, do not care about sets of display performance.With 2 generations of graphics card, joined the fan speed. Display is not big, then with King titanium HD-575X-YHF, the price is almost.With the West 500G single disc blue disk driveSama this power standard 350W, actually be taken in, it is a 300W on it. Over 300W, voltage, ripple and efficiency are not good. Mainly because it is the half bridge + passive PFC old structure, and the materials are not good. Recommend diamond Huntkey cold low-end Win7, basically it is.
From the angle of provincial electricity fee, how much power supply is suitable? Generally speaking, the power supply at 20% load above will have better conversion efficiency, and reach peak at about 40%-60%. As a result, the idle power of the host is no less than 20% of the total power supply, and no more than 60% under full load, which is the most ideal. So, choose the power rating, not all parts of the largest power consumption simply add up so easily.
Finally, the purchase of power, not only to look at the total power, but also 12V output, because the current CPU and graphics card, these two power hungry are dependent on 12V output. INTEL ATX2.3/2.31 version of the power specifications in the technical specifications, the middle and high-end power needs to use dual +12V design;Moreover, sometimes appropriate to improve the power level, but because of the conversion efficiency increases, but more energy saving. Make a simple analogy: you have a thicker, more advanced faucet in your house. Of course you can't say it will cost more water. How much water do you use to pay for the water?. Maybe the new faucet is more water saving because it solved the leaking problem of the small faucet before.
Power is not the greater the power the better, but the more suitable for your platform, the better, not necessarily high power, but also can not be lower than the minimum requirements of the platform, so that the operation will be unstable. The power consumption of the whole platform to understand clearly, plus 50~100W on this basis are just the power you need, do not blindly follow, the greater the power supply is not necessarily the most suitable for your platform.
