How to see the Power Plate

Believe that a lot of computer enthusiasts for the knowledge of hardware, focus on the CPU, graphics, small to memory, hard drives and other factors affecting the performance of the host. They may be able to position a certain part of the performance specifications of catchy, but once go to the computer city or the electric Power channel "actual combat", but always because of some obscure accessories previously shelved and doors.

Especially in the power of this aspect, as the computer hardware system behind the hero, although not determine the performance, but has a complex electrical structure, also has a profound knowledge. So, in the actual combat link, we can through the evil fill to understand your power? The answer is the nameplate.

　　One, why to see the power supply nameplate?

In fact, as a power editor, small more than everyone know, as an ordinary player to read a large amount of power evaluation articles, like a heavenly book general. If the search engine to find their interest in the power of the evaluation article, but because the article inside the complex terminology and do not know what to use the evaluation data and skip directly, only read the evaluation section at the end of the article.

There are complex circuits and materials

The lack of integrity of people leads to many times when we look at articles with a kind of critical emotional color. Therefore, to teach the fish as a fishing, learn a simple and easy to use the "evaluation" power, through the Hango can know the power of the high or low, why not?

Power suppliers also know this, after all, such as PFC, +12v output, gold and so on to indicate what we may not be able to explain. So the manufacturer directly on the power supply surface affixed to the nameplate, so that players directly through a simple number, you can see the power parameters, give yourself a reassuring.

　　second, the wool out of sheep, nameplate false odds?  

I believe many beginners, especially the cautious friend, will feel that the nameplate is the manufacturer's own printing, then the parameters how to draw, you can decide! What is the use of nameplate?

In fact, although the manufacturer has the freedom to draw their own nameplate, no one dares to cheat. Because the power supply is sold to consumers, if the consumer because you believe that your "fake" nameplate and the recruit, then touched the most the most the bottom line of business-integrity. (Of course, for the plot to make quick money and disregard the credibility of the cottage manufacturers is another matter)

No honest manufacturer, who dares to buy your product? Who dares to cooperate with you? So, no manufacturer wants to throw stones at their feet. So everyone can be assured through the nameplate to refer to.

　　Third, how to look at the power supply nameplate?

The nameplate is full of many parameters, so which parameters are we need to learn and attention?

　　1. Power supply

We know that the current power nameplate will be labeled two kinds of power: rated power, maximum power (peak power).

Rated power generally refers to the ability to continuously output the effective power, that is, in the normal working environment power supply can stabilize the output power. Rated power is a power supply the most important parameter specifications, if the power of the rated power can not meet the needs of your computer, all kinds of unpredictable problems will be followed.

Maximum power (peak power) refers to the power supply stable work can output the largest power, generally speaking, the maximum output power is higher than the rated power of some, generally a power supply of the maximum output power is its rated power of 1.3~1.6 times.

Previous power nameplate, often blurred the most important rated power, exaggerated the maximum power to confuse consumers. But with the power market of the fittest, there are no manufacturers dare to do so, after all, "rated power" of the four words have long been deep in the hearts of the public. So, we now see the Power nameplate, all with the obvious words to mark the rated power

As for the maximum power, in order to reduce the simultaneous occurrence of two power values resulting in the phenomenon of silly small white. Now the manufacturer plays down this concept, mainly gives the maximum power value of each output item, lets the consumer sum up by itself, obtains the maximum power value.

Therefore, now the general good power of the power labeling routine is: to emphasize the rated power, dilute the maximum power, to ensure a clear glance. If the current power supply even rated power is not displayed in a conspicuous position, it shows that the power supply manufacturers a bit "guilty".

　　2, all kinds of certification

To see the authentication information is an important step when purchasing power. To assess the quality of a power supply, you can first see if it has passed the necessary security certification. Generally speaking, the more reliable the quality of the power supply. Although a lot of certification is not necessary, but there is a certification is necessary, that is in the current market power supply, must be through the national compulsory 3C certification before sales.

Although we often ignore the 3C certification this point, but buy time to see more, whether there is a "CCC" logo, nor waste your too much time, also can let you buy a peace of mind.

-Plus authentication, is a symbol of high power conversion efficiency. Its certification requirements are through the integration of internal power supply, so that power supplies in 20%, 50% and 100% of the load point can achieve more than 80% of the power efficiency. For the plus certification, I believe we are familiar with the. The progress of the process and the cost of the base of the river, so that the current plus certification everywhere to go.

Therefore, the plus certification does not matter, the key depends on which level of the plus certification. At present, like the first horse gold 500W, Xin Valley gp600g and other mainstream power has passed the gold certification, some of the more high-end power also through high-grade platinum or even titanium certification, is the conversion efficiency of confidence, of course, the price is also rising. For ordinary players, the gold medal certification power is the current mainstream choice.

In addition to the above certification, some high-quality power supply will also pass the FCC certification, it is an electromagnetic interference certification. A power supply through the FCC certification will shield the electromagnetic interference from its work and eliminate the harm to the human body. In addition, in some advanced power supply will also see the UL certification mark, it is currently one of the world's most stringent certification, the power supply in the structure, materials, testing equipment and methods have related restrictions.

　　3. Output table of each road

Rated power, maximum power how do you get it? That's from the output of each road. With the current output of the hardware power gap is more and more, such as the independent graphics card is currently the largest export of power output, responsible for the output power parameters of the natural to pay more attention. Otherwise, only look at the total power, ignoring the output, if a certain way output can not meet the corresponding hardware appetite, it is easy to cause hardware instability.

By the nameplate of the current power supply, we can see the output of the main power supply, including +3.3v, +5v, +12v, -12v and +5VSB five kinds. +3.3V for motherboards and specific parts of the power supply, +5v for SSD power supply, +5VSB for the shutdown is still available USB power supply, -12V is responsible for the motherboard serial circuit output function. In general, the factory qualified power supply in these four outputs to meet the ATX power supply specifications, we do not need to pay more attention.

As for the +12v not mentioned, it is the key to see the output table of each road.

+12V is the most important power supply output voltage in the current system. CPU, graphics card power source is from +12v Road, at the same time mechanical hard disk, optical drive, such as hardware with mechanical structure of the motor part is to rely on +12v power supply, to meet the demand of 7200 rpm per minute.

+12V also divided into a single road +12v and two +12v two kinds of road. What difference does it make? In simple terms, the single channel +12v independently bear all the hardware on the platform power supply, output current bursts, can maximize the use of current, so single power conversion efficiency high, suitable for machine players.

Dual +12v refers to two outputs are responsible for the CPU and graphics card power supply, in the nameplate will appear "+12v1" and "+12v2" logo. Dual +12v output power supply will generally design a finite-current resistor, when the output current is too large, the general will trigger the protection of current-limiting resistors, so as to protect the power supply and other hardware. As a single channel Dabaogan CPU and graphics power supply, do not consider the multi-channel output of the "cross-border" problem, so generally do not have a limit resistance function.

But you do not understand the principle and good or bad, so as long as you remember the dual 12V mainly used in the mainstream low-end power supply, single 12V more used in high-grade power supply.
