PC power development should return to practical

Looking back at the development of PC power in the past fifteen years, except in the first few years, Intel has been trying hard to improve the so-called ATX specifications for its increasingly power-hung Pentium 4 CPUs. From 2005 until now, the changes in the ATX specifications have been described as minor repairs. Make up. The development of power supply seems to only increase the output power with the development of CPUs, motherboards, and graphics cards, or increase the number of output interfaces with different specifications, etc. The technical breakthrough is very few - take a power supply 10 years ago 10 years later on the computer, maybe you can use, then count the CPU pins, change several times?

I do not know when to start, the concept of conversion rate began to gradually attract the attention of the players, in the concept of "power saving" speculation, coupled with the evil emperor 80plus boosting, domestic and foreign manufacturers set off an upsurge in the pursuit of conversion rates, even once There is a saying "no 80, no high-end". So far on the market's high-end power supply, is still the only 80plus head start, no gold or gold medals are embarrassed to say that they are high-end goods - in fact, also tens of thousands of US dollars knife thing, and ultimately the bill is not a consumer.

I do not know when to start, "go back line" concept began to rise in the power market - that is, the power cord does not look good at the front, affecting the cooling, wind tunnels, all plug into the back of the chassis, and then cover up, so that heat Enough. This sounds like a sense, the calm power market has finally found a new direction, so the electromechanical joint efforts to jointly start a new round of speculation. However, this only makes the wire longer and does not have any technical content, and the cost does not increase much. The back line has gradually become the standard of the power supply.

What is the power of the game? Baidu, do not know recently, some manufacturers have begun to hype the so-called "game power" concept, although I can not call the game madman, but also reluctant to count a game player, want to think about really can not think of what kind of power to play The game is helpful - it really needs to be said that it can only be a big power, high-power power supply can support a stronger CPU and graphics card to deal with higher-end game configuration, but this is not entirely correct, you must know to do design, rendering, etc. Semi-professional graphics workstation configuration requirements are also very high, but in addition to power this thing really can not find other reasons called the game power supply, is there power supply can be optimized for the "Crysis 3" one?

As mentioned earlier, the development of the power supply is followed by two large power consumption CPUs and graphics cards, but in recent years, microelectronics technology has developed rapidly, and the manufacturing process has progressed step-by-step. Today, the mainstream CPU has fully entered the 22nm era. Since the beginning of last year it has grown to 28nm, and the development of the process will inevitably bring about a drop in power consumption - today's mainstream computer performance may have been more than 10 times 10 years ago, but the power consumption may be even lower than 10 years ago , This is why the author said that 10 years ago the power to get the computer 10 years later may be able to use the reason.

Although the high-end market is only a small number of enthusiasts can contact, but with the economic development, the computer anti-CPI guy gradually from the then high Shuaifu toys into a manpower now, the so-called high-end power and low-end but the difference between A few hundred dollars only, for CPU, graphics cards, these large numbers of K is only a small figure, but now with high-end configuration also no longer need super power supply, with the strongest single-core flagship graphics GTX Titan The most powerful CPU i7 3960x, for example, the sum of the two TDP has not yet exceeded 400 watts, coupled with other accessories with low power consumption, the whole number of 500 to 550 watts is more than enough, then kilowatts or even fifteen hundred What can be used to power the tile? supercomputer?

Judging from the current development trend, Intel's technology will certainly continue to improve in the next two years, and graphics cards will also be the same. In the future, even with the limit configuration of computers, the use of kilowatts of power has become a thing of the past, and even 500 watts or more will never be lost. No need. With the increasingly advanced architecture, the performance of a low-end IVB Celeron is sufficient to meet the daily Internet and office needs of most consumers. The standard office configuration power is only around 100 watts. There is no support for large power consumers. How should high-power power supply find its own market?

In fact, in the more homogenous PC market, the development of "plan-style" has been accompanied by the power market for many years. This is ultimately due to the relatively low technological content of the power supply itself, which has been inexhaustible for many years. The cottage and counterfeit goods are also one of the reasons for the crackdown on regular manufacturers investing in R&D. Price has always been a key consideration for consumers. Companies are forced to reduce R&D costs, shorten the R&D cycle, and directly purchase so-called “plans” for production.

In fact, more consumers who purchase power are non-professional, and they generally do not know much about the conversion rate and programs, which involve electronic technology. Moreover, the conversion rate also requires specialized instruments to test. What is the actual conversion rate? Only the manufacturers themselves and the IT media know that, in this environment of powerlessness and homogenization, where does the power supply go?

The author believes that in today's power is enough, the conversion efficiency is basically 70 to 80%, proving that the current PC power technology is very mature, the blue ocean market can be developed is not much, but the power will always be the PC can not In some cases, manufacturers should focus their R&D on workmanship and the added value that can be seen in fan noise control. After all, if the conversion rate cannot be tested, whether or not stability is the only criterion for judging the merits of a power supply.

Solving the noise problem is always more important than the previous "85plus" and the actual power supply is the heart of power supply to the PC. It is also an important factor in controlling the stability of the whole machine; the power supply will not increase the number of game frames, and the wire length and placement position. It will not have a huge impact on the performance of the computer; honestly doing a good job of every PCB board, checking every component, and fan noise is a bit smaller, these are already the best interpretations of the good power concept. Return to the nature of power, practical supremacy is the king of the power market.
