Individual buy parts, assemble a PC, the so-called Computer DIY has a considerable customer base, home applications, enthusiasts, professional design, both on the assembly machine soft spot. Assembled PC, has gone through a decade away, the original PC assembly machines, to attract users is its low price, and now, the price is just one part of the more attractive to users, and is higher than the brand configuration, the better performance. However, many aftermarket purchase but users are not familiar with, in front of a wide variety of accessories, it is a loss, or listening to a friend, or get from the media, but tend to focus on the graphics card, CPU, hard drive of choice, but Like ignore the most important thing: the chassis power. Many businesses in the configuration to the customer to fill a single, often filled vertical ATX chassis, or luxury ATX chassis, etc., without making specific statements. Why chassis power most important? First, in addition to a computer monitor, all parts are by the internal chassis laptop power supply, the power supply output DC directly affect the quality of parts, longevity and performance, the switching apple power adapter technology is concerned, it should be said has matured, including Many power supply manufacturers in Taiwan, the mainland also has factories supply the international market on the one hand, it also serves the mainland market, but many manufacturers face competition in the market tend to reduce the components, such as saving filter circuits, temperature measurement devices, etc. or the use of low-price components to reduce costs and improve market competitiveness. And this is often the victim user. Easily lead to poor computer power following questions:

One, leading to hard disk bad sectors or damaged; easily lead to a bad power supply false bad sectors hard disk, this failure generally can be repaired by the software. If there are users encounter such situations, the first thing to check is the laptop ac power adapter. At the same time repair the hard disk, the solution is to change a Rongsheng power. Over time otherwise prone to permanent damage, must return to factory repair, if you are a computer company, found that clients are more then repairing hard drive failure, but also to pay attention to what your company is using the brand's power to statistics and analysis. (Of course, frequently non-normal shutdown, may also lead to hard disk damage)

Second, the noise is involved: When you find your sound noisy, but you are buying is a good sound card, we should pay attention to your power supply.

Third, the CD-ROM drive performance is not good. If you are a new or newly bought computer with a CD-ROM to read the disk is not good, the reason may be that a great power, the CD-ROM itself is good.

Four, overclocking instability, there may be power.

Fifth, there is water ripples on the display, there is the power may be able to.

Six, the host baffling restart, there may be power.

Seven, install Windows often wrong,. CAB untied, there may be power.

Since the laptop battery charger is so important, how to identify good power it? First, look at the power circuit board work, good power, circuit board solder joints, devices are poor, compared with a larger gap; has good power filtering device, there is no difference, this is also very content to see out. Second, look at the brand and signage. On the market have a better power supply Roeyuta Rongsheng Power Wall Huntkey Power Supply

Some people may ask: Why are more than 300 pieces of the chassis is only 240W? 240W dell ac adapter enough? Indeed, some enclosures offer more than 200 pieces, but it marked a 300W or 350W, but they are not enough watts! That is their power to reach the target wattage (as some active speaker marked a 150W, while the actual power was only ten watts, you noticed that the highest bid thousand nominal power amplifier is only 150W x 2), and all Rongsheng watt power supply is enough! There is sufficient power margin!

Average user has only one hard disk, a CD-ROM drive, the display is connected to a separate power supply, 200W power supply is sufficient. (Unless you want to take more hard disk, optical drive, or CPU ... Those from a different matter)
