How To Build A Gaming PC For Cheap - The In-Depth Guide

mad scientist

One reason why many people don’t move over from consoles to PCs for gaming is because they believe that a gaming PC can be too expensive.


Whilst it is true that high end enthusiast PCs can go for £2000 or more, you can quite easily build a PC that runs most games for far cheaper. If you do go ahead with building a PC, not only will you be able to play the majority of games that are already on console, but you’ll have access to a wide range of indie games, too.


In this blog, I want to show you how you can build a gaming PC for cheap.


Step 1: Understanding and Buying Parts

The first step to building a gaming PC for cheap is to know which parts to buy. It can be a little confusing at first, but there’s a website that can do it all for you.

Not only that, but it can find the best prices for all of the parts you need and provide you quick links to buying these items online. The website I like to use is called PCpartpicker. Below, I’ve provided a look at all of the parts you will need. You can use the website to find the best prices for all of the items needed.


  • CPU
  • Motherboard
  • Memory
  • Storage
  • Video Card
  • Case
  • Power Supply
  • CD Drive
  • Windows


You may also need to buy a mouse, keyboard, and monitor if you haven’t got those already.


If you’re looking to go as cheap as possible, below is a build I made to offer the best bang for your buck. It includes a GTX 1050 Ti graphics card, 1TB of hard drive storage, a 120GB SSD for speeding up your Windows operating system and favourite games, and 8GB of RAM.


The processor is also good enough to deal with most tasks. The total cost of this system is £590.91.


  • CPU: Pentium G4560
  • Motherboard: MSI H110M PRO-VD PLUS LGA 1151
  • Memory: Crucial 8GB DDR4-2400 Memory
  • Storage 1: Western Digital Caviar Blue 1TB 3.5" 7200RPM Hard Drive
  • Storage 2: Kingston - A400 120GB 2.5" Solid State Drive
  • Case: Corsair - 200R ATX Case
  • Power Supply: Corsair CSM 550W 80+ Gold Certified
  • CD Drive: LG GH24NSD1
  • Operating System: Microsoft Home 10 OEM 64-bit

It’s more expensive than a new gaming console, but a gaming PC isn’t just for gaming. My main gaming PC is used for everything I do online. I can use it to play games, edit photos and videos, browse the internet, and pretty much anything else.


Step 2: Building The PC

The next step is to buy in the parts and build the PC.

This part can seem daunting, but when you understand the process, it can actually be quite fun! If you’d rather just buy the PC and have it built for you, you can find services like that online. If you choose this option, it will be a little more expensive, though.


Here are a few companies that can build you custom-made PCs at a lower price point:






If you’d rather build it yourself, find your parts on PC Parts Picker and then purchase them online. Once they’ve arrived, you can start building!


Building a PC is hard to do at first, but when you understand the basics, you’ll quickly realise that it’s almost like playing with big lego blocks. Everything has a position it goes into and it all slots into place quite easily.


You will need to screw in a few things, and if it isn’t turning on after finishing building, you may need to do a little bit of troubleshooting. (This is usually as simple as making sure everything is plugged in!)


I could explain everything in detail here about how to build a PC, but it would be far more efficient if you had a video to follow along the way. I’d recommend watching the video below.


It’s a long watch, but if you’re serious about building your own PC, this video will guide you through every step to building a PC successfully.


Step 3: The Conclusion

If at the end of it all, you have a brand new working gaming PC, you will have picked up three things.



Firstly, you’ll have a new gaming PC to use and play games on. Secondly, you will have learned more about PCs and how they work. Thirdly, you’ll now have a new skill! You will be able to build PCs and have a better understanding of troubleshooting them if something goes wrong.

Would 8gb of ram be enough for gaming nowadays?

@eluminea I think that 8GB of RAM is just enough for most games. In fact, most games use less than 4GB of RAM. It's just the outliers that may use 8GB or more. So, I think for a budget build you'd be able to get away with it. You'd have to be conservative with the programs you have in the background, however. 


Good article. Yes, there is a bit of recycling of the mobile news and views, so I think some articles in areas on the 'perimeter of mobile' would make a change and be interesting.




Reasonable advice. You need to make sure you are careful about electrostatic discharge when building. 


I would buy a portable USB DVD drive rather than an internal one.


Make sure you buy a good quality power supply unit - at least £40-£80. It will be the part you rarely upgrade, and cheap ones can literally ruin your system or cause errors. Even if your budget is limited it's a worthwhile investment. If you buy one with at least 600w you are future-proofing your system.


Oh and buy your RAM in pairs. Make sure it is inserted in the right slots. Two sticks of RAM will be quicker than a single module as long as they are installed in the right slots.


Good guide. Used to use my PC for gaming, but those days are long gone! Tend to just play mobile games now as they tend to fit into today's lifestyle - being able to play on the move and when you have a handful of spare minutes! PC and console games tend to be quite deep and involved, and unless you can dedicate a few hours of your daily life, progress is very slow and mastering the control's can be challenge.


I always biuld my PCs... I tend to reuse certain bits so I can get better components... Once you have a good case it should be good for a couple of builds. Same for my PSU. I spent a bit more initially so future updates could be done! 


Who cares? Building a PC from complete scratch is hard! But when the boards are already populated with individual components, requires a machine

Capable of fitting and soldering micro componates that a human can not.
