Computer DIY common misunderstanding what

Today we're going to talk about the basics, and the high-end mod is just a small crowd. DIY computer, simply put a bunch of hardware patchwork, composed of a complete host. And this, CPU, board card, memory, etc. are not too much of a problem. One is due to strict product specifications, the second is the product quantity is not high, the third is directly related to host performance, more attention. Mainly prone to problems or mechanical and electrical cooling products.

　　Chassis Shopping Error

　　1, only look at the appearance of ignoring compatibility

Many appearance control of the small partners like the appearance of beautiful chassis, and many mini chassis look good, very pleasing. So many players value the appearance and ignore the size of the chassis, compatibility. The first is that if the player chooses a standard ATX motherboard, then the Mini chassis is not supported, which players should note.

said the motherboard in the said graphics card, hard disk, want to get the fun of the game experience, a high-end graphics card function is self-evident, but now high-end graphics cards are very long, the ability to support the production of video cards is also an important consideration conditions. Some of the tower chassis will support long graphics cards at the expense of hard disk bits, and some mini enclosures simply cannot support them.

　　2, neglect of heat dissipation

The heat dissipation of the chassis is an important factor in measuring the quality of a chassis. The entire tower chassis has a large volume, heat dissipation is very in place. The main central tower chassis, also equipped with a number of fan bits, front, rear fan can be set up a horizontal duct. However, individual mini chassis due to limited space, there is no fan bit, players should pay attention to. If you prefer the Mini chassis, consider the following mini chassis.

　　To see some of the power of misunderstanding.

　　Typical example:

Mainstream support long video card in the Tower chassis: Game Titans Blade series, first horse "warrior" series, Xin Valley fighter C, Aviation Jia MVP

Excellent thermal performance Mini chassis: Tt core v1, pirate ship Air240

　　Power Purchase Error

　　1, blind pursuit of high-power

Power can be said to be the most fundamental parameters, the power of the host and the power to match, but many DIY novice does not know their host power in that Dan, so blindly pursue high-power power supply, so not only waste money, and conversion efficiency will be reduced. After Zhongguancun the conclusion of many times, the power supply is the most efficient when 40-60% load.

　　2, blind pursuit of efficiency

Power conversion efficiency is also an important parameter, according to 80plus can be divided into white cards, bronze, silver, gold, white gold. However, there are businesses in order to save costs, no certification, but the power itself is not poor efficiency. To take a step back, the bronze power supply and the gold price of 500W or so may be very large, and the efficiency of the increase is not significant, the election of gold is not necessarily suitable for all players.

　　3, ignoring the Power interface

Although the Power interface can not calculate the power parameters, but the hardware of the host is closely related. The most easily overlooked is the interface of the graphics card. The most entry-level video card can be powered by PCI, while the top video card requires 2 8pin connectors. Like the shadow of 770 people Hall will need dual 8pin, and the public version of Asus 290X is 6pin+8pin. Not only that, but even the same power of 500W power, some equipped with dual 8pin, while others are only 8pin and 6pin. This is also the need to pay attention to players.

　　4, Blind pursuit of modular interface

Modular interface power source has been in the high-end power supply, but now more and more popular to civilian-level power, so many players blindly follow, not the module does not buy. The same parameters of the two 600W power supply, modules in the module price to a lot of difference, and did not bring any quality improvement, so the choice of modules may not be suitable.

Summary: Here I give players summed up on the selection of several misunderstandings, although it is not a big problem, but players if all understand, not only can have a clearer understanding of the power supply, purchase time can also be more emboldened to avoid being fooled. Next look at some of the heat sink errors.

　　Typical example:

500W power supply, dual 8pin: aviation ka mvp500

500W power supply, 8pin+6pin: Titanium grams vp500p

　　Radiator Purchase Error

　　1, ignore the third party radiator

Players are aware that CPU is divided into boxed and bulk, boxed with a radiator, but the heat sink with the radiator is very general, if the entry-level CPU is OK, but the players to start with high-end CPU or play overclocking, then or in addition to choose a radiator more suitable. At present, can be divided into air-cooled, heat pipe (air-cooled), one water-cooled, in general, cooling capacity is to be gradually upgraded.

　　2, ignore the heatsink size

First of all, heat pipe (air-cooled) radiator, generally can be divided into side-blown and lower pressure type. Side-blown heat dissipation is relatively superior, but due to the larger size, some chassis may not be installed, will be directly to the chassis side panel. Consumers also need to pay more attention to purchase, especially the narrow chassis may not be compatible with the high tower side of the cold.

For the above chassis is not compatible with the situation, players may wish to choose the lower pressure radiator, which can effectively avoid the problem of compatibility. However, it is necessary to note that the choice of pressure-type air-cooled, but also ITX motherboard, it is necessary to see whether the radiator block the position of the memory, the author's experience is that the vest is basically unable to install the memory.

Then is one water cooled, can according to the cold row size divides into 120, 240, 360, in general, the mainstream of the tower chassis are supported 120 water-cooled, can be directly installed in the chassis behind the fan bit, but 240 water-cooled is not every chassis can be installed. Players can only observe the board's upper edge and the top of the chassis space, if very small, it is certainly impossible to install. So choose 240 water-cooled users to be cautious.

Summary: This part mainly talked about the purchase of some of the attention of the radiator, is mainly the size of the problem, because the factors restricting the size of the radiator, so the author listed for your reference. As for how to choose air-cooled, water-cooled, each person's needs are different, and I believe that some players choose water cooling just for the sake of good, it will not be discussed.

　　Typical example:

Tower side blow: Kyushu wind and Ice 400, overclocking three east China Sea X4

Lower pressure type: Kyushu, the "Eagle" and "Cool" series

One water-cooled: Game Titans LC120, Tt Water 3.0

　　Installed error

　　1. Ignore Silicone grease

Mentioned earlier on the chassis, power, heat dissipation of some of the misunderstandings, and then look at the installed time some error-prone problems. The first is silicone grease smear, the author found two extremes. One is to apply a thick layer, the other is to ignore the existence of silicone grease, do not apply. None of this is advisable. Silicone grease is to make up the contact between the cold head and the CPU gap, so only need to evenly apply a thin layer on it.

2, the power supply is reversed

The second is the power of the fan bit, because the chassis power fan is used to absorb the wind, if the power supply fan upward, it will absorb the top card generated by the hot air, is not conducive to power dissipation.

3, the radiator direction is not right

The third is the direction of the radiator, in general, the airflow inside the chassis is from the front backward, so the side-blown radiator, the fan should be placed in front of the cold row, so as to the cold wind back.

Summary: Today I give you a summary of the DIY field, electromechanical products in the purchase time of some misunderstandings and installed easy to make mistakes, although these misunderstandings are not serious, but it is a lot of DIY novice easy to make mistakes, and sometimes it is these casual details did not notice, causing their own losses.
