If you are going to buy a new computer or just a system unit, you should not immediately run to the nearest computer hardware store and buy a ready-made, already assembled computer. Selling ready-made solutions (for a store) is the most profitable option, because not every buyer understands the peculiarities of assembling a computer.
Necessary
The choice of component parts of the computer
Instructions
Step 1
Selection of peripheral devices such as a computer mouse, keyboard, etc. you can leave immediately before the purchase. The monitor and any external devices are also selected at the last moment. The choice of component parts of the system unit and the case itself should be based on what you want to get from the computer.
Step 2
It is best to choose a case of a system unit with a built-in power supply, as a rule, it turns out that its price is 20-30% lower than the option "case" and "power supply". It is preferable to choose a good case manufacturer, for example, Foxconn, the price is much higher than that of other manufacturers, but time shows that "the avaricious pays twice." When choosing a case, you should also pay attention to the power of the built-in power supply. For most personal computer users, the 450-500W option is suitable.
Step 3
Choosing a motherboard. First of all, select a processor, and based on the selected process, select a motherboard. Among the existing solutions, you can choose processors more expensive (from Intel) and cheaper (from AMD), when you compare their performance. When choosing the number of cores and the frequency of the processor, you should rely on such a parameter as the cache. The higher the cache, the better the performance. If you have a choice between a 2-core processor with 8 MB of cache or a 4-core processor with 3 MB of cache, go for the first option. Depending on the operating system you install on your future computer, not all processor cores reveal their potential. For example, Windows XP uses a maximum of 2 cores and 3 GB of RAM.
Step 4
The choice of RAM should be approached as carefully as possible. If possible, select memory with high performance ratings. If your motherboard has only 2 slots for RAM brackets, it is advisable to choose one bracket, but with a larger volume. The amount of RAM should be chosen according to personal needs, 4 Gb sticks should be enough for you to work with office and graphic applications.
Step 5
The graphics card is also worth choosing depending on your video memory needs. For example, Intel I3 processors include a video processor, which eliminates the need for a video card for tasks that are not difficult for the processor itself. When choosing a brand of video card, it is difficult to say that one is better and the other is worse.
Step 6
There is a saying: "There is never enough hard disk". In fact, this is how it turns out. No matter how much disk space is on the hard disk, it will always be insufficient. Because several hard disks can be installed in the system unit, it is advisable to purchase a large disk (from 1 Tb).
Step 7
Once all the main parts of the system unit have been selected, you can start assembling. Today, most stores specializing in the sale and assembly of computers carry out free assembly of the system unit (subject to the purchase of component parts).
