If you are a beginner on the road to building a PC, the knowledge below will be presented to you as a hand-held guide to lead you out of a maze of things to learn. Asked that if not careful, he will get into a "hell of a fire".

Just imagine, building a PC is like playing a lego game. Everything in the lego world needs to be put in its right place and in order for it to be perfect, the colors and the order of the pieces need to have a certain order that corresponds to each other. Similarly, not all components in the machine can assemble with other components, but need the appropriate ports and appropriate performance, your computer will fight in all "arenas". Here we will go into more detail about the parts you need to keep in mind when starting to intend to build case:

1. Price
Not every component that the first thing you should think about when building a PC for yourself is the budget you will spend on it. This completely depends on each individual because each build will have different purposes and interests. If you only need to play games with "normal" graphics requirements that are not as sublime as Dota 2, LoL, Hearthstone or Overwatch, a computer with a price range of 10-15 million is enough but if you want to play Ultra settings, it's a completely different story.

In addition, balancing the budget when selecting and buying components is also an important issue to be aware of. You can't spend too much money on VGA but forget that there are other motherboards or power supplies.

2. CPU
With the CPU, there are a few important things to keep in mind, and also one of the metrics that assess whether your computer is running strong and efficient:

Core : CPU currently on the market can be roughly divided into 4 common types: 2 core, 4 core, 6 core, 8 core. Of course the higher the multiplier the stronger the CPU but that is only true when you compare CPUs in the same series. For example, Intel's 6-core i7 chip is still stronger than AMD's 8-core FX as usual. Another important thing is that with the higher the multiplier, the performance is also increased, but do you need to use such high performance? In my opinion, with Intel (popular and recommended chips), only 4-core chip can study, entertain comfortably without worry.

Heartbeat: Of course the higher the clock, the better the computer's working rotation. But similar to the multiplier, the clock should only be compared by the same line chips. For example, Pentium 4 3.0 GHz is naturally much inferior to the 1.7 GHz i3 chip. The reason is because i3 chips have more cores. By the way, a little more about the multiplier, each core can be considered to have a single clock, for example, 2 cores 2 GHz chip, each operating core has a clock speed of 2 GHz. But this does not necessarily mean that the machine has a high clock and many cores will run well on the software. Many software is still designed to be single-threaded, so it only focuses on one core of the computer, resulting in poor performance. Anyway, you are assured because today,

Cache (cache): This is the third part should be concerned every time you choose a certain chip. Currently, all types of chips are popular with cache from 3 MB to 8 MB. The main feature of the cache is actually only useful when used with tasks that consume a lot of bandwidth such as encode or compress video (perhaps more useful for youtubers). When buying a chip, you should not choose the model with a cache too low (less than 3 MB), choose a range of 6 MB is okay.

3. Mainboard

After selecting the chip we continue to choose to the mainboard. There are many articles on how to choose the first mainboard component because the motherboard is like a foundation of a house and has a new foundation to build. This is true but I personally find that if you choose the chip first, when choosing the mainboard, it will be easier to choose the socket (socket) for the chip, which is easy to upgrade later.

Chipsets : Chipsets are the most important part of the mainboard (saying so, but I also feel important at all). The simple explanation is for the CPU, RAM, VGA or other peripherals to pass data smoothly to each other via the chipset. Not only that, the chipset also supports other functions such as integrated graphics card, sound or USB 3.0 port, ... And the last important thing when choosing a chipset is that you have to consider whether it supports your CPU. have chosen no.

Socket : Each mainboard will usually support certain types of chips with certain ports. For example, currently, Intel's chips are mainly divided into 4 socket types: LGA2011, LGA1155, LGA1150, LGA1151. Of these 4 types, LGA1150 and LGA1151 are the latest and will be supported for at least the next few years, so if you want to build a PC right now, you should choose one of these two types, and if you want to keep This handbook to save money to buy later, you should note about the new socket type that Intel provides, advanced technology so now obsolete very quickly. As for AMD, now using AM3 + and AM4 ports is the best.

RAM : The types of RAM used on motherboards include technology standards, bus speeds, and the number of slots allowed. The remaining problem when choosing is mainly to see how fast the main support speed, how much the clock. For example, the MSI B150M Mortar with DDR4 2133 MHz slot is too delicious and sufficient, and is also very popular with PC builders.

4. PSU

PSU or Power Supply or power supply is the heart of the computer. The power supply is extremely important because its operating power is excessive, it will cause a shortage of electricity, it will cause a power failure, sometimes both the component damage and certainly the heart without pumping. full blood for the body will not be okay.

Capacity : See the power, the first is to look through how much it runs. The capacity must meet the performance of components, especially the graphics card and then the chip. When choosing a chip and vga, you should see how much performance you need, the more power you save, the cheaper price you have to put in the PSU. Currently the trend of graphics cards and cpu are taking full advantage of the power-saving ability, so choosing the power capacity, I suggest that the range of 500W or more with gaming builders using mid-range graphics cards, and range 600W or more if using high-end, high-performance card lines.

Trademark: Brands and power supply certificates are equally important after looking at capacity. To have a healthy heart, you need to know if this heart is genuine or not. If the bad types of nursing, the box recorded 600W, when brought back to run only 300W and then fire the card, the source of the fire at that time did not know who to call. When choosing a PSU, pay attention to the source's 80 Plus certificate. This certificate checks to see if your power supply is 80% or more when used at 10, 20, 50 and 100% of its performance. There will be 5 levels granted under this certificate, including: Bronze, Silver, Gold, Platinum, Titanium. In general, once you have received this certificate, using Bronze is quite enough and fits your pocket. In addition, you should also check out some reputable psu manufacturers such as: Acbel, Cooler Master, Seasonic, Thermaltek,

5. RAM

This is also easy to see. Usually when building a gaming PC we can choose between 8GB and 16GB. In fact, because RAM is also easy to upgrade, at first, just plug in 1 8 GB stick It is important that you consider whether the DDR RAM and support on the motherboard are compatible (for example, the same DDR4 and the operating frequency of RAM is less than or equal to the support frequency on the main). Currently DDR4 is the best and the latest, even cheaper than DDR3 so I highly recommend this type.

6. VGA

Graphics cards are actually the most talked about thing, but for those who are playing the game or starting to build a PC, surely have learned a lot about this issue. Currently, the latest two GTX graphics cards are 1080 and 1070 with the power of "monsters" have been released, and Nvidia's rival AMD, owning RX480 card will also be released at the end. June with power "asymptotic" GTX 1070 but cheap nearly half. Readers can learn more to increase the ability to choose about GTX 1080 and 1070 here , and RX 480 here . Additional note is that when choosing a graphics card, it is still necessary to look over whether the main has a compatible slot.

7. Some other details

To complete the missing case, I would like to point to name a few components that are indispensable but do not need to go too deep to learn the professional indicators here:

Cooler (heat sink): In the summer, melting fat, you need to air conditioner, your computer needs cooling fans only. In fact, quite a few hot components of the machine are also equipped with heat sink fans already. But sometimes this is still not enough because computer gaming must also operate with quite high capacity. Even high temperatures also cause dangerous conditions such as jerky engine, slow running, sometimes even reset or spontaneously shut down the device. Here I will not note anything more about the index or performance of the cooling fan, but please give a few reputable manufacturers that you can buy such as Cooler Master, Deep Cool, ... And you should also remove the cover case out to sweep, wipe dust regularly because the computer is easy to get stuck but too much dust sometimes stuck to the fan, that's not kidding.

Case : The case , the least important part but the most beautiful part because the outsiders look at it, of course, look at its case first. Many people who like mod leds will choose cases with transparent body covers, then wiring and arranging components so that they are neat and beautiful. In the framework for all newcomers and learn how to build a PC, I will only briefly mention some criteria when choosing a case.

The first is the size, there are 5 types of case sizes depending on the components, the main size, the length of the graphics card that you choose accordingly. The easiest is that you ask the salesperson to advise personal fit. Anyway, I am not too serious about the problem of beautiful strings, just fit the hardware inside and the price is okay.

Secondly, it is equally important to choose a case cover so that the ability to escape heat and space to install the "high-air-cooling" cooling fan is smooth. Things to note about the case's heat-release issues are the placement of the heat sink fan, above, behind, and not to get in the way of other items.

Storage (HDD / SSD): Choosing a hard drive (HDD) or optical drive (SSD) is always a top concern every step to this section. Each type of drive has its own advantages and disadvantages. SSDs use flash memory with read and write speeds much faster than HDDs, but the price of SSDs is not "flexible" at all. HDD speed is not comparable with HDD but its memory contains more capacity and the price is also more affordable. If you buy an SSD now, people often buy an external hard drive to store more data. Therefore, the hard drive should be considered so that it is affordable and suitable for use.


Above is an introduction to the basics and summarized so that those who do not know much about the hardware and the notes when building cases can easily grasp. Because it is a summary, it is inevitable for abbreviations, so if you read something you do not understand and want to clarify, do not hesitate to leave a comment below. Have a nice day!
