How to assemble a computer yourself?

Purchase of components

In order to assemble a computer at home, we need:

  • Monitor;
  • System unit case;
  • Power Supply;
  • Motherboard;
  • CPU;
  • Graphics card;
  • Memory card;
  • Cooling cooler;
  • HDD;
  • DVD drive
  • SATA cables
  • Peripheral devices (keyboard, mouse, speakers, webcam).

We will make a reservation that in this article there will be no recommendations which particular spare parts are better to buy. First of all, it depends entirely on your goals. Secondly, new modifications of computer components are constantly appearing on the market, and any recommendations on this subject become obsolete within a few months.

If you have acquired everything you need to work, you can begin to connect the parts to each other.

Computer connection

  1. Unscrew the side wall from the housing. Place the power supply in the special grooves in the upper left corner of the far wall of the housing. Screw the unit to the back wall with screws.
  2. Remove the motherboard cover from the back of the chassis. It is unlikely that it will fit the board that you bought. But complete with the board there is always a plug suitable for it in configuration. Insert it into the grooves of the back wall.
  3. Install and lock the motherboard to the back of the chassis. There should be a gap between the board and the chassis. To create a gap on the wall of the housing, special bushings are pre-screwed (supplied with the housing).
  4. Open the processor socket cover. Find a cut corner on your processor, align it with the same corner of the socket. Insert the processor into the socket and close the cover.
  5. Attach a cooling cooler to the motherboard. Insert the wire coming from the cooler into the corresponding connector on the motherboard.
  6. Install the hard drive in a special compartment. It is located on the right side of the case. Attach the hard drive to the chassis using screws.
  7. Install a DVD drive in another special bay. Before that, remove the plug from the front wall of the housing blocking access to this compartment.
  8. Insert one or two memory cards into the dedicated slots on the motherboard. Beforehand, figure out how to properly bend and return the clips.
  9. Now the most confusing moment. Cable connection. Find from the bundle of wires going from the power supply, those that go to the processor and motherboard. If you are confused, use the instructions for the motherboard. Then connect the wires from the power supply to the drive and hard drive.
  10. Connect the drive and hard drive to the motherboard using SATA cables.
  11. Now connect the cables from the front panel of the computer to the main board. This is the cable from the buttons "Start" and "Reboot", power indicator, USB ports and headphone jacks. All wires are signed and inserted into the corresponding connectors. If confused, refer to the instructions.
  12. Insert the graphics card into the PCI-Express slot on the main board. Close the housing cover.

Connecting external devices to the system unit

Insert the cable from the monitor into the video card connector on the rear panel of the case and fix it with screws.

Now you know how to connect the computer correctly. If you did everything right, then your computer is ready to use.

How to connect wires to a computer

Hello everyone, OFFisnik is with you again, and today you will see the back wall of your computer, well, who did not see of course. In today’s lesson we will pull the wires. After all, very often it happens that the keyboard does not work with the mouse, or some wire just fell off, and for everything to be normal we need to know How to connect wires to a computer.

As you know, a computer consists of 2 main parts, this is the “System unit”, where the brains, memory and heart of our computer are actually assembled, and the “Monitor”, so to speak, the TV through which we see the picture.

If the monitor does not work, then most often the wire from the monitor falls off. On the back wall of the monitor you won’t get lost, there are only two “Power” connectors (from 220 and plug into the outlet) and, let’s call it “Another wire”, which connects to the “System unit”. Just in case, here:

But in the “System Unit”, as you can see, there are a lot of colored, interesting, unusual connectors that you have probably never met, but are not afraid of, because for you studying a computer is an interesting and informative process. And here you will read how to clean your computer from dust.
The connectors may vary in location and appearance. But if you look in detail, that is, the Standard connectors that all system units have, we need them. Just note that there is something on the back of your PC. What is highlighted are the connectors for the wires, so remember to know how to connect the wires to the computer.

Connector No. 1: Actually as on the monitor, this is 220 power.

Connector No. 2: A keyboard with a mouse (special slots for them), by color we look what and where to stick, there are arrows on the wires.

Connector No. 3: USB and Network. USB is a variety of USB flash drives. Mice and keyboards, printers and more. Network is actually a network cable, our favorite Internet.

Connector No. 4: Maybe 3 sockets. These are the columns. If the speakers are ordinary, then only stick into the green connector, it is usually central). If there is a mega 5: 1 music system, then we are already looking at the color.

Connector No. 5: There can be any connectors (boards are inserted into the system unit). But most often here comes the wire from the monitor, yes that is the “Other wire” on the monitor.

Important. If you have a blue connector, for the monitor at the top and bottom, then insert it into the bottom. It is at the bottom of the Video Card that transfers the image, in this case there will be a backup option at the top, in case it burns out.

Well, to make it even easier, if you do not know where to put the wire, then stick in the color and you will not be mistaken). Red-red, blue-blue, we are sappers removed)))

In conclusion, I will say that if you are not sure that you are correctly connecting the wire to the computer, then focus on the color, usually the color of the connector matches the color of the wire. Red-red, blue-blue, we are sappers removed)))

Now in the case when something does not work for you, you can always know how to connect wires to a computer.

How to connect the power supply to the computer correctly

Do not underestimate the importance of the computer’s power source. A good power supply is the cornerstone of the stability and reliability of your computer. However, it happens that for some reason the power supply needs to be replaced. But do not be afraid. Replacing it is an amazingly simple process. It is more difficult to choose it correctly.

How to disconnect your old power supply

Start by unplugging all the power cables that are connected to the computer. If your power supply has a switch located on the back of the computer, turn it off (off), and then remove the side panel of your PC.

You will need to disconnect all cables that go from the power supply to the motherboard.

Note: The main 20 or 24 pin connector is most often fixed with a key. Before removing the connector, slide the key to prevent mechanical damage to the board or connector.

Also, do not forget to remove the four- or eight-pin processor power connector located next to the processor connector on the motherboard (not all motherboards have it).

In order not to get confused when connecting, you can photograph the wiring of power cables. So you will be sure which cable is connected to which components.

After disconnecting each cable, remove the power supply from the case to avoid tangling it with other cables. This will also ensure that all power cables have been disconnected.

To remove the power supply, unscrew the screws that hold it in the housing. In most cases, there are only four screws, but designs may vary, depending on the manufacturer.

Installing a new power supply

Make sure that the power of the power supply is sufficient to fully power your computer. The processor and graphics card will use the most power. If there is not enough power, your computer may run slowly or not start at all.

Make sure that the power source you buy will match your form factor. This is usually ATX or mATX.

Turn the computer over on its side. This provides the best access to the installation location of the power supply.

Open the computer case. In order to access the power supply, you may need to remove some of the PC components. Most often this is a processor cooler.

Install the power supply in the computer case. Most modern buildings have a special chassis, which greatly simplifies installation. If not, install a new power supply, just like the previous one.

Make sure that all the fans on the power supply are not blocked and that it aligns with all 4 screws on the case. If this is not the case, the power supply may not be installed correctly.

Tighten all fixing screws outside and inside the housing.

Connect the connectors. After the computer’s power supply is locked, you can start connecting the power cables to the computer’s motherboard.

Note: make sure that no component is forgotten and place the wires so that they do not interfere with the coolers. If you still have unused cables from the power supply, carefully fold them to the side (if there is a cable tie, you can use it).

Connect the 20/24 pin connector to the motherboard. This is the largest connector on the power supply. Most modern motherboards require a 24-pin connector, while older motherboards will only use the first 20 pins. Some power supplies have a removable 4-pin connector to make connecting older motherboards easier.

Connect the 12V power to the motherboard. Older motherboards use a 4-pin connector, and newer 8-pin ones. It provides power to the processor and should be clearly indicated on the cable or in the documentation for your power supply.

Connect your graphics card. Mid-range and high-end graphics systems require one or more 6- and 8-pin connectors. They will be marked as PCI-E.

Close the system unit cover. Plug in the power supply and make sure the switch on the back is on.

Turn on the computer. If everything is connected and working properly, the fan on the power supply should turn on, and your computer will boot normally. If you hear a beep and nothing happens, then most likely something inside is not connected correctly or the power source does not provide enough power for your components.
