Building a custom gaming PC doesn’t have to break the bank. With smarter component choices and a bit of DIY spirit, you can create a powerful setup for less than you might think. In this 2025 guide, we’ll show you how to build a custom gaming PC on a budget without sacrificing performance—perfect for gamers who want control and value.
Planning Your Build: Budget and Needs First
Before shopping, define your budget and gaming goals.
- Target budget: £600–£900 is ideal for budget-conscious builders.

- Storage (SSD/HDD)
- PSU (power supply)
- Case
- Optional: CPU cooler, case fans, RGB lighting
