Required Parts to Building a Gaming PC

If you are new to building your own custom gaming computer, this article will introduce you to the main components that make up a gaming PC. These components will be the guts of your gaming machine, so you need to choose them carefully. Starting with perhaps the most important part of any computer system:

CPU / Processor

The Central Processing Unit (also known as the processor) is considered the brains of a computer. It does all the mathematical calculations that the software asks it to. Without a decent CPU in your gaming PC, your games won't run very fast.


If the CPU is the brains of a computer, then the motherboard is the heart. All other components connect to the motherboard one way or another, so it acts as the hub of all the components in your PC. If you lack a good motherboard in your system, your gaming PC won't perform well no matter how good your other components are.


The RAM (Random Access Memory) in a computer is the memory that running programs rely on. The more RAM you put in your gaming PC, the faster your programs and games will run.

Hard Drive

The hard drive is used to store all your programs and data. You need a hard drive big enough to fit all your stuff on it, without it clogging up due to lack of room.

Graphics Card

The graphics card (also known as video card) will be one of the most important parts of your gaming PC. It is the component responsible for drawing all the 3D graphics and special effects that you see in the games you play. You need to get a good graphics card to be able to play the latest games in all their glory.

Case and Power Supply

Pretty self explanatory, the computer case houses all your precious little components under one roof. The power supply provides power to your PC. These two components are essential for a working gaming PC.


We have covered the main workhorse components that you will need to build your gaming PC with. You should also consider other components such as a sound card, networking card, and CD/DVD Drive, amongst others, to complete your gaming PC.
