When assembling a personal computer is very importantnot only correctly install all components in the case, but also correctly connect the wires to the motherboard. It does not take much time, because all connectors have unique dimensions and do not interface with other interfaces.

If you just started building a computer, then it will be useful to learn how to connect the motherboard.

How to connect the wires to the motherboard of a modern PC?

First, make sure that all components, such as power supply, hard drive and optical drives, are correctly installed. After that you can start connecting the wires:

Connect the widest connector of the power supply (it usually consists of 20 or 24 pins) to the motherboard. It is used to control the power supply.
Connect the square plug from the power supply to the corresponding connector on the board. Thanks to him, the current is fed to the central processor.
Now you can connect a cable to the floppy drive (used to read and write floppy disks). It is slightly smaller than the IDE connectors for hard drives.
Connect the loops of the hard drive and optical drives to the motherboard. This is either a small flat SATA connector with 4 contacts, or a wide IDE ATA connector for 40 contacts.
After that, the buttons are connected to the motherboard.

Do not forget that all connectors must be connected as tightly as possible to ensure a stable connection.

Connecting the buttons to the motherboard

To connect the power button, reset and LEDs from the front panel, find the 9 plugs at the bottom of the motherboard:

In the upper row, connect in turn the wires with the inscriptions: PLED +, PLED-, PWRBTN, GND;
In the bottom row, connect in turn: HDLED +, HDLED-, GND, RESET, DUMMY.
