Best Budget Gaming PCs under £400

For people looking to get into PC gaming, all the different specs and components can make it seem like a daunting task. At Alex Davis PCs, we offer a wide range of high-quality prebuilt desktops, saving you the hassle of building it yourself. Whether you’re new to PC gaming or a veteran gamer looking for the best budget gaming PCs under £400, look no further than these selected systems.

Is a Budget Gaming PC Right for You?

Before we dive into the best budget prebuilt gaming PCs, let’s look at what makes these units cost less than some of our higher-end systems.

Computers are made of multiple parts that each serve a different function. For example, the CPU, or the PC’s ‘brain’, runs applications and processes instructions, which is crucial not just for games but for any kind of software. On the other hand, the GPU is responsible for visualising said software by rendering graphics, affecting the resolution, frame rate, and fidelity.

Another important thing to keep in mind is random access memory, or RAM. Think of it like the computer’s short-term memory, storing data currently in use by the GPU and CPU, which is reset when the computer is rebooted. Less demanding games such as Minecraft, Fortnite, and Grand Theft Auto V can run comfortably with 8GB of RAM, while more intensive titles like Star Citizen, Microsoft Flight Simulator, and Indiana Jones and the Great Circle are recommended for systems with 32GB of RAM due to more complex environments and graphics.

The final thing to consider is storage space. This is essentially the computer’s long-term memory, and determines just how much data and how many programmes can be stored on the computer. If you plan on downloading multiple games onto your computer at once, look for a system with higher storage, or you could increase the storage amount with an external hard drive.

Higher-end gaming PCs containing premium components can run more complex games with higher graphical fidelity and advanced effects such as ray tracing. Put simply, if you’re looking to play the latest and greatest blockbusters at max performance, you may want to invest in a more advanced system. But for the best gaming PCs on a budget that are still capable of running the majority of popular titles, read on:
