How to assemble a PC system unit

Unfortunately, most users do not know how to assemble a computer system unit and it seems that only these "weird guys from IT" can do it. In fact, at the present time, the assembly of the system unit, for which many companies selling computers charge several thousand rubles, is very simple. Assembling, for example, an airplane model or a LEGO children's construction set is much more difficult. Someone, of course, is ready to pay these several thousand for their peace of mind and time, but if you communicate or plan to communicate with the computer on "you", it is better to master the self-assembly.

The step-by-step instructions for building a PC will clearly show you the simplicity. The article was written on an example of assembling a computer based on an Intel processor, but there are no significant differences in assembly between Intel and AMD.

Let's figure out the composition of the components that we need to assemble the system unit with our own hands from scratch.

What you need to build your computer:

  1. Processor and cooler for it;
  2. Motherboard;
  3. Video card;
  4. RAM;
  5. Hard disk;
  6. CD (DVD) drive;
  7. Housing;
  8. Power supply unit.

Please note that good cases are sold, as a rule, without a power supply unit and you will have to purchase it separately.

For assembly, we need a Phillips screwdriver and, possibly, pliers. I recommend doing all operations with utmost care, since the components are quite easy to damage.

We'll start by sorting out the wires and installing the power supply, if purchased separately. The power supply is installed in the rear upper corner of the case with the fan outward. It is not difficult to guess intuitively about its position. The place where the motherboard is attached must be cleared of the wires, at the same time having figured out their shapeless heap.

Next, we will install the processor on the motherboard. The processor is perhaps the most delicate part of a computer's gut. In addition, it is the smallest, but far from important, part of the computer.

The most delicate part of it is the legs - they are very thin and very easy to bend. We open the clip on the motherboard and, focusing on the "cut" corner of the processor, install it in the slot. Then close the clamp. This operation, I must say, is not for the faint of heart, because often, in order to clamp the processor and fix the clamp, a significant enough effort is required. It seems that you press a little more and the processor will crack or bend, at least. Here it is necessary to overcome the nerves and close the clamp with the effort of muscles and will.

Next, let's install the CPU cooler. If you buy an Intel processor, take the boxed version - follow the link to buy coolers for pc box intel cooler, you can't go wrong. If you did so, then your cooler is already smeared with thermal paste, otherwise, apply thermal paste to the surface of the fan, which will touch the processor. Before fixing it on the motherboard, look where the power cable from the cooler will be connected (if you didn’t find it, look in the instructions for the board and find its diagram there), after you have decided on the correct position relative to the power wire, fasten the locks and you're done.

Now let's set the RAM sticks. Here I recommend checking the instructions for the motherboard - it should say in what order the slots should be filled. When installing the bracket, you must unclench the clamps on both sides of the slot, insert the strip into the slot and press evenly on the edges until the clamps snap into place.

After that, you can install the board into the case. First of all, we look at how the external connectors on the motherboard are oriented and, based on this, we install the socket under them, which always comes with the board, in the back of the case. Immediately, I recommend inserting a mat. board to the case, try on the video card for the PCI slot and see which of the plugs in the lower part of the case needs to be broken out for it. Do this without the mat being screwed on. the boards are much simpler in my opinion. We screw it into special holes in the "support" body in accordance with the number of mounting holes in the board. We insert it into the case, check if we placed the panel correctly under the external connectors and, if everything is normal, we fasten the board. You do not need to tighten the bolts too much - you can damage the fragile parts of the motherboard.

The motherboard is installed, now we will install the remains of iron: CD (DVD) drive and hard disk. The hard drive is installed in the lower front of the system unit. Place it on the rails and secure with screws or a special mount if you have one. To mount the disk drive, you will need to remove the plastic cap on the outer part of the case in the desired place and break the iron cap behind it, then insert the drive from the outside and secure it with bolts or fasteners on the side.

Now all that remains is to install the video card, for which we have already broken the cap. We simply insert it into the PCI slot and secure it with a screw in the place of the cap.

All the hardware is installed and in order for our system unit to work, you need to connect all this iron with a heap of wires that should have stayed with you. With the drive and hard drive, everything is simple: there are two types of data connectors - IDE (legacy) and SATA. The length of the first connector immediately gives it out - it is about 6 centimeters, respectively, this is the widest cable. Modern computers and hardware are made for small and neat SATA connectors, so just make sure your CD drive and hard drive don't have 6cm wide inputs on the back and grab the bright red SATA connector wires. You need to intuitively or following the instructions to find the place of attachment of the SATA wires on the motherboard and, fixing it there, stretch the ends of the wire to your devices. Next, lead the power wires from the power supply to them, and also lead the power to the motherboard itself.

In the system unit, you should have dangling wires with plastic narrow lugs with the inscriptions POWER LED, HDD LED, and so on. These are indicators - the very same light bulbs on the front of the system unit. Find two rows of pins on the motherboard, making up ~ 12 pairs and you will see similar labels next to them. Also on the board itself, or in the figure in the instructions, the polarity of the installation of the wires is indicated.

A wire of a uniform color always has a "plus" polarity, a wire of the same color with a black stripe, respectively, "minus".

Perhaps your video card needs additional power (in this case, there is a wire from it). In accordance with the similar connectors on the board and the instructions for it, we determine the attachment point for the add. nutrition. We do the same with additional coolers on the case, if any.

That's all, actually! We connect the monitor, keyboard, mouse, power to the system unit and try to start it. If everything works, starts, then close the lid of the system unit and start installing Windows. Hooray, now you know how to assemble a computer system unit and you can do it yourself, saving several thousand when buying a new computer!
