The higher the rated power of computer power, the more charge it

As the heart of the computer hardware system, although the power supply does not determine the performance, it determines the stability and durability of performance. Our knowledge of the power supply is wrapped in a metal shell. This also greatly reduced our understanding of the power supply, we need only through the power supply nameplate, Power module composition and so on can see the origin of power and quality. However, although this is not enough, because of artificial misleading and network rumors prone to a lot of power errors. Today, we have to put the right, to take you to understand the current common power error.

  Misunderstanding one: Only look at the rated power

In the past, we earnestly, the power supply should not only look at the power given by the manufacturer, to find out the actual rated power. Because the previous JS often in the most high-power and rated power, often the maximum power mark in the obvious position to mislead consumers. Now, manufacturers have learned to behave, the rated power to a conspicuous position. Does this mean that the power of the consumer to look at the power has become more relaxed and happy? Small knitting look, not necessarily!

  We used to look at the rated power, but it's not enough.

Times in the development of our computer power consumption from the main CPU shift Cheng Xianka mainly, CPU for the times. Due to the exemplary relationship of ATX Power design, 12V is the most important output voltage in the current power supply system. CPU, graphics card power source is from the 12V road. Therefore, sometimes it is more important to look at the output power of the 12V than to see the rated power, which determines the stability of your power supply .

12V output power and 12V output power accounted for the key, many manufacturers pay attention to this point

Generally speaking, a power supply 12V output ability, probably can judge the whole power load capacity, in other words, is a power supply depends on the 12V power of the ratio, 12V output power ratio, the power quality, generally more than 80%. We can bear this in mind.

  Misunderstanding two: The higher the rated power, the more the cost of electricity

Many friends will feel, my home computer maximum power is 200, 300W or so, buy a 500W power supply is waste also more than, high fixed power also consumes electricity. Is that the case?

2000W rated power power supply?

  In fact, the higher the rated power, the greater the cost of a priori error . The power of the PC is completely determined by the consumption of the hardware, and the PC is just an "energy pool", and the larger the wattage, the more electricity it can load.

In fact, to see consumption without electricity, the impact factor is very complex, and the most important is the power conversion efficiency, so why do we attach importance to the reason of the certificate.

The conversion efficiency of the power supply is usually highest under 50~60% load

Don't say don't know, high-wattage number of power supply, due to the more sophisticated components, so in the conversion efficiency is often higher, from the load curve can be seen in the 50~60% load, the power conversion efficiency is usually the highest, which not only means to save electricity, but also means to save energy.

400-500w power supply is the best choice for the current household

Therefore, the appropriate choice of the power of the number of stalls, in many aspects, there are certain benefits, and also for future upgrades left the corresponding load space, of course, certainly, at the price is certainly higher than the low wattage, as to whether this money is worth the flowers, but also to see the specific actual situation of users, there is a need to upgrade, You may consider the High-wattage number power supply.

  Misunderstanding three: module power is better than non-module

Module power supply, free collocation, install on demand, save space, enhance the impression. Seemingly modular power supplies have an innate advantage, and we often praise the benefits of modular power on power channels. So consumers have a common understanding that the module power supply must be better than the non module.

Full Module power supply

Not necessarily. From a cost-effective point of view, the modular power supply is indeed a bit higher, more out of the price, consumers can choose better performance of the hardware, or if you are obsessive-compulsive disorder of course can directly select back to the module power. From the user's point of view, if positioning is an entry-level home, office, learning machine, it does not necessarily require modular power. If you plan to build a light effect, multiple graphics video RAID hardware, the main game and other multiple systems, then need module power.

There's always a risk in the plug.

Module Power also has a key problem, is the module power supply is through the module circuit PCB board as a medium and then output to the module wire, so the voltage stability will also be reduced, while the module power supply than the non-modular power supply of the probability of bad contact is also high, but the modular power supply for the line is also an indisputable fact.

Not only to see the module does not module, the quality of the power itself is also important

Generally speaking, the module power supply must be better than the module power supply, this is not established, the internal components of the power supply, the circuit scheme is the impact of the fundamental quality of power. And the performance of the players, should pay attention to conversion efficiency, 12V accounted for important factors. Therefore, in the purchase of power when you must not the cart before the horse.
