How to Assemble a Complete Desktop Computer

Desktop Computer Assembling is easy. It usually takes up to 30 minutes to assemble a Complete Desktop PC. In my other articles I have written about how to install various components of a Desktop PC. Today I am gonna take you through the steps of Assembling a Complete Desktop PC:

1. Gather all the components needed.

2. Attach the Power Supply (PSU) with the PC Case.

3. Install the Processor (CPU) in the Motherboard.

4. Install the CPU Cooling Fan on it.

5. Install the Motherboard in the Case.

6. Make the Front Panel connections.

7. Install the RAM in the Motherboard.

8. Add an Optical Disk (CD/DVD/Blu-Ray) Drive.

9. Add a Hard Disk Drive.

10. Install a Graphics Card (Optional).

11. Install a extra PCI Card if you need.

12. Close the Case.

11. Make the External Connections (Monitor, Mouse, Keyboard, Printer, Scanner, Power etc.).

12. Start the Computer.

13. Install an Operating System (Windows, Linux, Mac etc.).

14. And finally its over.

How To Add a Power Supply to a Computer Case

Power Supply supplies electricity to a PC. To add a PSU with a computer you need to:

1. Remove the PSU cover.

2. Set the PSU in the case so that the screw holes of both the things are met properly (Usually at top).

3. Attach the PSU by adding the screws to the holes.

4. Grab the fat power cable and connect it to the motherboard's big main power port.

5. Grab the small 4 pin power cable and connect it to the power port beside the processor (CPU) port.

Required Parts to Assemble a Desktop PC

First step of building a PC is collecting the required parts. Here is what you need to assemble a desktop computer:-

1. Case - A case is needed to set all the devices of the computer in it.

2. Power Supply Unit (PSU) - To supply power to the devices of the computer we need a Power Supply. If you buy a case it will probably have a built in PSU in it. You can work with it with a less powerful PC. But for a much powerful PC you will have to buy a PSU of greater Watt.

3. Motherboard - Motherboard is the main circuit board of a computer which connects the other devices.

4. Processor (CPU) - The Central Processing Unit works as the brain of a computer. All the computations are done by it.

5. Random Access Memory (RAM) - RAM is used to temporarily store programs which are currently running.

6. Storage Devices - For storing data for a long time we need storage devices. We can either use Hard Disk Drive (HDD) or Solid State Drive (SSD).

7. Optical Disk Drive - CD, DVD or other optical devices are read or written by the optical disk drives.

8. Keyboard - Keyboard is used for giving input by typing.

9. Mouse - Mouse is needed for giving commands by clicking.

10. Printer - For printing documents.

11. Scanner - Used for scanning documents.

12. Graphics Card (GPU) - Graphical Processing Unit is needed for high quality graphical output.

13. Operating System Disk - You'll need an OS disk to install the Operating System which will run the computer.

14. Monitor - We can see graphical representation of our work in the monitor. There are many types of monitor. Most common are: CRT, LCD and LED.

15. Speaker - This is where we hear the sounds from.

This is almost everything you'll need to assemble a complete PC. There are some optional devices like Floppy disk, Sound Card, TV Card etc.
