Essential Parts of a PC

Before you build your PC, you need the right parts; that’s why we’re here.

Picking the right components for the PC you need can be an awful process first, but once you look into it, you’ll see that it’s not only so simple, but it can give much fun.

This article will show you what essential PC components you need for your PC, gather up the right parts, and start putting it piece by piece until you can have that dream build that you have always been dreaming of.

All right, Let’s do this!

What do you need?

Processor (CPU)

The Central Processing Unit is the brainpower of the PC. It instructs your PC on working together as a whole and essential parts of all PCs. The two leading manufacturers are mainly Intel and AMD; if you are a hardcore gamer and streamer, we suggest looking into Intel and AMD for PCs who want to do more applications and productivity.

CPU Heat Sink & Fans

All CPU generates heat, and keeping your PC’s CPU at the right temperature is one of the most critical things to maintain a stable and working PC. There are many different kinds of heat sinks, from Fans to Liquid Cooling; all these help a PC keep cool. Think of it as a car radiator; it can draw away from that heat from your PC.


The Motherboard is a large board that connects all your PC; it allows communication between the other hardware.

The Motherboard you need will depend on what CPU you purchased and what kind of other features it provides, like overclocking, RGB lighting, and other connectivity options, so always keep a lookout on what type of Motherboard you need.

Check out this breakdown on how to choose a motherboard for all the info you’ll need to make an informed decision.

Memory/Random Access Memory (RAM)

Random Access Memory (RAM) is a fundamental part of your PC’s short-term memory. It keeps data you use regularly and accessible, so your PC doesn’t have to access another storage device every time you need to use that data. It’s different from your primary storage devices; the RAM always resets when it doesn’t have power.

The more RAM, the better, but you can’t have too much RAM, but for practical purposes, most gaming systems will be OK with 16GB or 32GB if you want to keep your PC viable for several years.

Video Card (GPU)


The Video Card is an essential component for your ultimate gaming experience. The GPU will help your PC do the complex graphic calculations that making your PC game looks good. Many laptops and PC has already have integrated graphics installed, but it is still recommendable to install and GPU for your gaming experience.

Storage consists of all your PC files, programs, applications, and your operating system (OS). Two types of storage devices used today, hard disk drives (HDD) and solid-state drives (SSD), they are similar, but the SSD is the newer version of the HDD; they are both used because SSD is still quite expensive nowadays, so we suggest to buy both SSD and HDD combined to optimize you PC’s performance.

Power Supply Unit (PSU)

The Power Supply Unit (PSU) provides power and electricity for your PC and functions. It’s also essential to research efficiencies, wattage, and quality if you build a more complex PC. If you have a Graphics Card (GPU) or a Liquid Cool CPU Heat sink, we recommend more PSU wattage and quality. An excellent tool to look at is the power supply calculator, in which you can see what power requirements you’ll need to build your PC.

Case Fans

The Case Fans is a fan attached to the computer case to give mo active cooling for your PC; most computer fans commonly come in standard sizes and are powered using 3-pin or 4-pin fan connectors. It is like the exhaust fan for your PC and is also essential considering installing this.


This depends on what your PC is capable of and makes. Any gaming PC needs a 144Hz or even 240Hz, for the best gaming experience. But if you are using the computer for Office encoding or Home Schooling, then a lower and cheaper resolution monitor is what you need.


Just like the monitor, the mouse also depends on what your PC style is. If it is for games, you need more like mappable buttons or change the DPI and colors. But the most important on mouse usage is comfort.

Computer Case

A computer case, also known as a computer frame, tower, system unit, or cabinet, is a metal or plastic box that contains all of the components of a personal computer. Manufacturers use steel, aluminum, and plastic for the production of PC cases. The Case is the shell of all the PC; it is essential to have an issue with good airflow to be cooling within the PC case. It also has different shapes and sizes, from mini cases to full tower cases. You should check your Motherboard on what kind or size you need for your Case.

Operating System (OS)

The operating system(OS) is an essential part of your PC; the operating system is the one that makes you interact with your PC; it is like the middle of the bridge between you and the PC.
