Computer assembly

I graduated from a computer. In college, computer assembly and maintenance is a more practical course. In the class, everyone must have assembled a computer. It is quite interesting. After graduation, the most important thing is to myself. I can buy accessories to assemble a computer. After all, the difference between desktop and notebook performance is too large, not an order of magnitude.
After working for half a year, I got a little bit of savings and finally got my wish. Hahaha! Interesting!

First of all, the computer hardware part includes the following parts: CPU, motherboard, graphics card, memory module, hard disk, monitor. Of course, what are the audio, headset, keyboard, mouse and so on.

1. CPU: At present, there are only two processor manufacturers: Intel and AMD. Only Intel is introduced here. Everyone knows that the CPU currently has i3, i5, i7. Here, I will introduce you to the suffix.
Desktop processor:

1. X suffix: Extreme level, best performance. A bit expensive……

2. K suffix: Supports overclocking, but we usually do n’t use it. You may need to use overclocking for live broadcast of large games (explain a little overclocking, for example, CPU frequency of 3.6GHZ, you can overclock to 4.0GHZ without damaging the CPU), but it is possible. After all, I am not very specific. The price is slightly higher. Note: If the CPU supports overclocking, the motherboard you bought must also support overclocking, otherwise the CPU will not overclock.

3. F suffix: Removed the built-in nuclear display, the most cost-effective. Personally recommend buying this (frequency 2.9GHZ). However, please note: additional exclusive display is required. Of course, those who like to play games will definitely buy the exclusive display, so the nuclear display will not be needed. An additional reminder: if you install a standalone display, the monitor interface should be connected to the standalone display, not the motherboard. The monitor interface on the motherboard needs to be verified.
   The processor I bought is: i5-9400F, which can be said to be the most cost-effective, the price is around 1200. The price of i5-9600KF is around 1400. Now it seems that an i5-10400F comes out.
   In fact, when playing games, i5 is enough, just buy a better graphics card. If you have money and willfulness, buy high-end ones.

4. Some other suffixes (such as S, T, etc.), S suffix means low voltage processor, T suffix means ultra low voltage processor. I wo n’t say anything about these things, and I do n’t recommend buying them.

Notebook processor:

1. X suffix: Needless to say, the most advanced and expensive.
2. Q suffix: 4 core to high performance processor
3. H suffix: high-voltage non-removable processor, soldered to the motherboard of the laptop, it is not possible to replace the CPU
4. HQ suffix: When buying a game book, we may often see it. 4-core to high-performance processor soldered on the computer motherboard.
5. Suffix M: Standard voltage processor
6. U suffix: When we buy office notebooks, we should often see this
7. Y suffix: If the ultra-low voltage processor
   needs to buy a notebook, only office is needed, U suffix is ​​enough, if you want to play games, H, HQ suffix.

Understand CPU production briefly: The
mysterious CPU is actually made of sand . When I first knew it, I was completely ashamed. I did n’t expect that the expensive CPU was actually made of valuable sand. It was incredible. Only Intel and AMD can make CPUs in the world. And, even more incredible it is that there are CPU transistor billions of dollars .

Briefly talk about the production process: extract silicon from sand, to achieve 99.9% -----> make silicon into silicon ingots, slice it (imagine, similar to cutting carrot slices) -----> use For a long time, engrave several layers on the slice to make transistors -----> Finally, build the connection circuit between the transistors -----> Next, we will start to enter the test phase. The
general process is like this. Probably enough. In short, it is very difficult to produce and takes a long time.

Second, the motherboard:
If the CPU you buy supports overclocking, the motherboard must buy a motherboard that supports CPU overclocking. ASUS motherboard is recommended here .
ASUS motherboard series: ROG series, TUF series, ROG STRIX series, PRIME series
There are three models in each series. Z stands for high-end, B stands for mid-end, and H stands for low-end . If we play games, we usually buy B mid-end. . Z-type motherboards support overclocking, some are expensive, and some of them also support WiFi .

I personally bought the ASUS TUF B360M PLUS GAMING S motherboard (4 ddr4 slots, 2 M.2 interfaces, 6 SATA interfaces, 1 DVI interface and 1 HDMI interface), does not support overclocking.

Tips: When assembling the computer by yourself, first install the CPU fan base on the motherboard, then install the metal sheet, then start to tighten the screws to fix the motherboard to the chassis, then start to plug the remaining wires on the power supply Fortunately, on the motherboard.

Third, the graphics card
low-end graphics card: GTX 580 or less
mid-range graphics card: GTX 580-GTX 1660, personally bought is GTX 1660, the price is around 1600. The power supply must be at least 450W.
High-end graphics cards: RTX series, these graphics cards are too expensive, not an order of magnitude. High-end series. At the same time, the power requirements are also very high.

Fourth, the memory
stick What kind of memory stick does the motherboard support, what kind of memory stick do you buy, generally 8 G is enough, if the memory is a little higher, buy two is enough. Of course, if you want to save money, you can buy fish, but there is no quality guarantee. The official website is slightly more expensive, a DDR4 8G memory stick is about 300. What fish, about 180.

Fifth, the hard drive
Personally recommend that you buy a solid-state and 1T mechanical hard drive with M.2 interface. Solid-state hard drives (120G is definitely enough, about 200 yuan) are dedicated to the system, and mechanical hard drives are used to store data. Personally think that solid state plus machinery is the best combination.

Sixth, power
This seems unimportant, but extremely important. The power supply supplies power to the motherboard and the graphics card. The weight is very heavy. The power of the power supply is very important , mainly depends on how much power your graphics card needs, such as the GTX 1660 graphics card I bought, which requires 450W for the power of the power supply. If the power supply is insufficient, it will not be able to achieve the performance it deserves.

Seven, display: Here, talk about the display interface: VGA, DVI, HDMI, DP
VGA: an older interface that transmits analog signals, and the following interfaces all transmit digital signals. The graphics card and the monitor directly transmit digital signals without loss of signal, which means that no distortion will occur.
DVI: Because the interface is relatively wide, plugging and unplugging is not very convenient. Support high resolution.
HDMI: Similar to DVI, except that it transmits digital signals as well as audio signals. What do you mean? In other words, if your monitor comes with a stereo, you only need to plug in a HDMI cable, no need to plug in an additional audio interface. HDMI supports up to 4K resolution. Now HDMI interface is more common. However, there are fewer monitors with built-in audio.
DP: Similar to HDMI, audio signals can also be transmitted simultaneously. Support higher 8K resolution.

to sum up

When personally assembling the computer, it is necessary to pay attention to: the CPU interface of the power supply (now generally 4 + 4P pin, formerly 3 + 3 pin) and the interface of the graphics card ((6 + 2) P * 2) Don't connect these two interfaces wrongly. One interface supplies power to the CPU and one interface supplies power to the graphics card.
The more important point is that the power on, restart button, power light, etc., these interfaces must not be mistaken.
As for the other interfaces, the size is unique, just a fool operation.

The problems that may occur when the device is turned on after the assembly is complete: the
dots are not bright, and the device cannot be turned on: 1. The problem of the memory module 2. The problem of the graphics card interface 3. The power-on and restart of the chassis are wrong

Finally, attach my host diagram:
