Building a PC requires careful consideration of the hardware components that go into it. These parts are what determine the machine’s performance and capabilities, so making informed decisions about them is essential. Here are some of the hardware components you’ll need to build a functional PC:


A motherboard is the heart of any computer system. The central circuit board connects all the components in a computer, including the CPU, memory, storage devices, and expansion slots. Without a motherboard, a computer cannot function.

The motherboard has several critical functions that are essential for proper operation. First and foremost, it provides power to all the components connected to it. Either an external power supply or an integrated power supply unit on the motherboard supplies this power. Additionally, it regulates data flow between various components using buses (data pathways) on its surface.

Choosing the correct motherboard can be overwhelming due to the many options available in today’s market. Motherboards come in different sizes and form factors, such as ATX (Advanced Technology Extended), Micro-ATX (mATX), and Mini-ITX (mITX). Choosing the correct motherboard is vital to ensure that all the other components in your PC are compatible and work together smoothly.

Central Processing Unit

The CPU handles all instructions related to computing tasks, such as running applications or browsing the web. It consists of several cores that handle different tasks simultaneously, making it one of the most significant components in performance. When selecting a CPU for your build, consider clock speed, core count, cache size, and power consumption factors. These elements will determine how fast your computer runs and how much electricity it consumes.


One of the essential parts you’ll need for your build is RAM (Random Access Memory). This hardware component helps your computer perform multiple tasks simultaneously without slowing down.

When it comes to RAM, it’s essential to know what type of motherboard you have, as they come in different sizes and support different types of RAM. DDR4 is the most common type used in modern motherboards and offers faster speed than its predecessors. The amount of RAM depends on your intended use – for basic browsing and office work, 8GB should suffice, but for gaming or video editing, at least 16GB is recommended.

Installing RAM into your motherboard is straightforward; align the notches and gently push down until it clicks into place.


One of the most important is the SSD (Solid-State Drive), the primary storage for your operating system, applications, and files. Unlike traditional hard drives, SSDs use flash memory to store data and offer faster read/write speeds.

In addition to an SSD, you’ll also need a CPU (Central Processing Unit), which acts as the brain of your computer. The CPU handles all calculations and instructions for running software programs and interacting with hardware components. When selecting a CPU, consider clock speed, number of cores, and power consumption based on your usage needs.

Power Supply

A power supply unit (PSU) is responsible for powering all of the internal components in your PC, including the motherboard, processor, graphics card and hard drive.

When choosing a PSU for your PC build, it’s important to consider several factors such as wattage output and efficiency rating. The wattage output determines how much power your PSU can deliver to your system. An efficient PSU ensures that electricity is not wasted as heat when converting AC power from an outlet to DC power that can be used by computer parts. This reduces energy consumption and lowers electric bills while also discharging less heat into your system.

System cooling

Building a PC requires some knowledge of the hardware parts involved in the process. One crucial aspect of building your PC is selecting the right system cooling method. The cooling system significantly impacts your PC’s performance and longevity, so it’s essential to choose wisely.

The primary purpose of a cooling system is to dissipate heat generated by various components such as the CPU, graphics card, motherboard, and power supply unit. Several types of cooling methods are available in the market today, including air-cooling systems, liquid-cooling systems, and hybrid cooling systems. Each system type has advantages and disadvantages based on cost, noise level, complexity, and efficiency.

In general terms, air coolers are more affordable than liquid coolers but can be noisier depending on the fan’s quality.

Graphics Processing Unit

The GPU plays a crucial role in rendering images and video on your computer screen, making it an essential component for gamers, content creators, and professionals who work with graphics-heavy applications.

When choosing a GPU, there are various factors to consider. Firstly, you need to decide on your budget and what kind of performance you’re looking for. If you’re building a high-end gaming PC or workstation, then investing in a powerful graphics card like NVIDIA’s GeForce RTX series or AMD’s Radeon RX 6000 series is recommended. These GPUs offer excellent performance when it comes to running demanding games and applications at higher resolutions and frame rates.

Operating System

The operating system (OS) is an essential software component for communication between hardware and software programs. It acts as an interface between the computer’s hardware and its applications. Before deciding what OS to install on your new PC, you must ensure compatibility with other components, such as drivers and peripherals like printers or scanners.

Which tools do you need to build a PC?

Building your PC can be a rewarding experience, but it requires specific tools to get the job done. The right set of tools will make building your PC easier and ensure you don’t damage any components. Here are some essential tools you’ll need to build a PC.


One of the most important tools that you will require when building a PC is a screwdriver. Without it, you won’t be able to fix the motherboard or attach other parts like hard drives and power supplies.

When choosing a screwdriver for your PC build, consider purchasing one with magnetic tips as this makes picking up small screws much easier. Furthermore, ensure that your screwdriver has different sizes of bits because not all screws in your system are uniform in size. Opting for one with comfortable grips will also help prevent hand fatigue during extended periods of use.

Apart from the main screwdrivers, there are other tools that come handy when building a PC like pliers for holding onto tiny screws or bending metal brackets into shape if required.

Hex nut driver

One such tool is the hex nut driver, which can come in handy when assembling certain components.

The hex nut driver is a small tool that allows you to tighten or loosen nuts with hexagonal heads. This type of fastener is commonly found on computer cases, power supplies, and other components. Using a regular screwdriver or pliers can damage the nut and make it difficult to remove or tighten properly.

In addition to a hex nut driver, there are several other tools required for building a PC. These include screwdrivers (both Phillips and flathead), pliers, wire cutters/strippers, zip ties, thermal paste applicator, and an anti-static wrist strap.

Thermal Paste

Thermal paste fills the microscopic gaps between your CPU and heat sink, ensuring efficient heat transfer away from your processor. Without thermal paste, an air gap between these two components would cause overheating issues and lead to reduced performance or even hardware failure over time. Choosing a suitable thermal paste can make all the difference in how well your computer runs.

When selecting thermal paste for your build, consider its composition, consistency, and application method.


Building your PC is a great way to get the best possible performance from your computer. By selecting the right components and assembling them yourself, you can ensure your system is tailored to your needs.
