Why Build Your Own PC?
Although pre-built systems are convenient, they often include unnecessary components or lack the precise specifications you need. Additionally, when you build a PC, you can choose every part, which ensures better performance, easier upgrades, and often a lower overall cost. You also gain essential technical knowledge that helps with future maintenance.
Furthermore, a custom PC allows you to prioritise graphics, processing power, storage, or cooling depending on how you use your device. For example, gamers may need a powerful GPU, while video editors may prefer more RAM and fast NVMe storage. Because of these advantages, many people in the UK now prefer to Build their own PC rather than purchase a standard model.
Step 1: Plan Your Build and Set a Budget
Before starting the pc building process, you must establish a clear budget. The price of a complete system can vary significantly based on whether you intend to use it for work, gaming, or creative tasks. However, consider the long-term value of future upgrades. Once you set your budget, create a list of required components so that you have a clear roadmap from the beginning.
Additionally, planning is essential because it determines how effectively you can match your parts. For instance, choosing a processor automatically influences your choice of motherboard. Furthermore, a well-organised plan prevents compatibility issues and ensures the Build your own PC project goes smoothly.
Step 2: Choose the Essential Components for PC Building
To build a PC, you will need the following parts:
✔ Processor (CPU)
Acts as the brain of your system. Intel and AMD both offer strong options.

- AMD Radeon RX 7800 XT – Excellent value alternative with strong editing and rendering performance.
✔ Storage (SSD or HDD)
Fast NVMe SSDs significantly improve system responsiveness.
Recommended High-Rated Storage:
- Samsung 990 Pro 1TB NVMe SSD – One of the fastest consumer SSDs available.
- WD Black SN850X 1TB NVMe SSD – Excellent read/write speeds and strong durability.
✔ Power Supply (PSU)
Choose a reliable PSU with enough wattage to support all components.
Recommended High-Rated PSUs:
- Corsair RM750e (750W, 80+ Gold) – Silent, efficient, and ideal for mid-to-high-end builds.
- Seasonic Focus GX-750 (750W, 80+ Gold) – Highly trusted in the PC building community for long-term stability.
✔ Case
This houses all components and affects airflow and cooling.
Recommended High-Rated Cases:
- NZXT H7 Flow – Exceptional airflow, clean layout, easy to build in.
- Corsair 4000D Airflow – Popular for beginners and experts due to excellent ventilation.
✔ Cooling System
Most CPUs include a stock cooler, although performance builds may require aftermarket cooling.
Recommended High-Rated Coolers:
- Dark Rock 4 – Quiet, powerful air-cooling solution.
- Corsair iCUE H100i Elite Capellix (AIO Liquid Cooler) – Great temperatures for high-performance CPUs.
Although many beginners rush to buy parts, take time to compare specifications carefully. Additionally, check compatibility charts to ensure your motherboard supports your CPU, RAM speed, and connection types. Moreover, this step is essential for a successful pc building experience.
Step 3: Prepare Your Workspace (Build Your Own PC workspace)
Once all parts arrive, create a clean and static-free environment. Although you do not need advanced tools, a screwdriver set and good lighting are helpful. Also, keep all manuals nearby because they often include diagrams that simplify installation. Furthermore, preparing your workspace ensures a smoother Build your own PC process and reduces the risk of damaging components.
Step 4: Assemble the Core Components
The following steps outline the physical assembly:
1. Install the CPU
Carefully place the CPU into the motherboard socket. Ensure it aligns correctly before closing the latch.
2. Add the RAM
Insert RAM sticks into the appropriate slots until they click into place.
3. Mount the Motherboard
Place the motherboard inside your case and secure it with screws.
4. Install Storage
Slot your SSD or HDD into the designated bay or M.2 slot.
5. Install the Power Supply
Position the PSU in its compartment and route the cables neatly.
6. Add the GPU
Insert the graphics card into the PCIe slot and tighten the securing screws.
Although assembling a custom PC may look complicated, the procedure becomes much easier when followed step by step. In fact, most components are designed to fit securely in only one correct position, which significantly reduces the chance of errors.
Step 5: Connect Cables and Power On
Once everything is in place, begin connecting the cables. This includes the 24-pin motherboard power cable, CPU power cable, SSD connections, fan cables, and GPU cables. Although cable management can feel tedious, neat organisation improves airflow and makes future upgrades easier. Additionally, clear cable routing helps troubleshoot any issues later.
After connecting all components, switch on your PC. If everything is connected correctly, the system will power on and display a BIOS screen. This stage confirms that your Build your own PC project has been assembled successfully.
Step 6: Install the Operating System
After your system boots into the BIOS, set your boot priority to USB and install Windows, Linux, or another operating system. Once installation begins, follow the on-screen steps. Although this stage is straightforward, ensure you download the necessary drivers for your GPU, motherboard, and Wi-Fi adapter. Installing drivers ensures smoother performance and stable functionality.
Step 7: Test and Optimise Your Custom PC
Once your system is running, begin testing the hardware. You can check temperatures, run benchmark tests, and install any essential applications. Although some users overlook optimisation, it plays an important role in ensuring long-term performance. Additionally, monitor your system regularly so that you can manage updates or upgrades whenever needed.
By this stage, your pc building process is complete. Additionally, you should now have a fully functioning machine tailored to your needs. Because you selected every component yourself, you can expect better long-term flexibility and easier future upgrades.
