Build Your Own PC

There are many things to consider when building your own gaming PC. You need to decide on the perfect hardware for your needs. These then need to be compatible and work cohesively together. In addition to this, a stylish PC case is a must, but it also has to be large enough to handle all your chosen hardware. Then there’s the more advanced stuff like water-cooling, modding, add-ons – it’s enough to trigger the anxiety and send you running for the hills. But take a deep breath, this ever-updating DIY PC hub is going to answer all your questions and more. Plus, if it doesn’t answer your questions, let us know and we will endeavour to fill those blanks for you. So, stock up on snacks, because we have a lot of ground to cover! 

Why Build Your Own PC?

First of all, we think it’s important to know why you should build your own gaming PC. It’s more than just the bragging rights, we swear. When crafting a gaming PC, you can engineer it to your own specific needs, budget, and gameplay style. If you’re big on farming sims and little else, then an overclocked Intel Core i9 or AMD Ryzen 9 is going to be a little bit overkill. (Don’t worry, I’m calling out my own gaming habits here.) Alternatively, if you’re a streaming superstar, sharing AAA gameplay in 4K with your beloved audience, then elite-tier hardware is going to be your go-to. 

We each require something a little bit different from our gaming PCs, so building your own is the best way to perfect your specification. It ensures you get exactly what you need, without all the extra fluff! 

Building a PC

What do You Need to Build a Gaming PC? 

We’ve covered why, now it’s what. What do you need to build a gaming PC? This is where the overwhelming diversity in form factors, generational tech, and brands can get a little much. Because there is literally so much to choose from. The Overclockers UK website, alone, has thousands of products to peruse and we specialise in gaming hardware. Imagine if we sold everything! Cue the fainting cartoon gifs. 

To keep things simple for a hot second, there are seven must-have components that you need to craft a gaming PC. These are a motherboard, processor (CPU), memory (RAM), graphics card (GPU), storage, power supply unit (PSU), and a PC case to keep it all in. You will also need a cooling system, but we’ll cover that later! 

It could be argued that a graphics card is not 100% essential, as many CPUs include integrated graphics, but we’re operating on the assumption that this is a gaming PC you’re building. A dedicated GPU is always better when a PC’s primary function is gaming. This is also true for content creators and streamers. Before you say anything, we know PC case is technically not a component, but you do absolutely need one for building a computer. Unless you have the mad skills to make one out of Lego, then who I am to stop you? 

Tangents aside, these seven pieces of kit are essential for building a gaming PC. But this is where it gets a little trickier. You need to ensure these components are compatible and will all fit inside your case. If you buy a motherboard with an Intel chipset but buy an AMD Ryzen 7000 Series CPU, you’re going to run into problems. Equally, an E-ATX motherboard is not going to fit inside a Mini-ITX PC case. Therefore, when you’re buying the individual components, you need to think of the gaming PC as a whole, too.

Core Components

To help with that, let’s go over each of these must-haves in a little more detail. We’ll be talking about the latest generations of hardware and popular previous editions that are still available. 


This is the foundation for your gaming PC. All the other hardware connects and interfaces through it. No mobo, no function. Motherboards are primed to work with one brand of processor. If you want an Intel Core processor, you need a motherboard equipped with an Intel chipset and socket. Which chipset and socket is then determined by which generation processor you want. For example, if you wanted a 14th Gen Intel CPU, you’d need a motherboard with a 600 or 700 Series chipset and LGA1700 socket. Thankfully, motherboard product and manufacturer pages usually detail which processors are compatible. Here is a handy table to give you a quick overview: 

LGA 1700B660
Intel12th Gen (Alder Lake)
13th Gen (Raptor Lake)
14th Gen (Raptor Lake-S)

The CPU, otherwise known as the central processing unit, is the brain of your gaming PC. It controls all the things. Utilising a combination of cores and threads, your workload, games, and applications are intelligently managed, keeping your PC running smoothly and efficiently. There are two main brands to choose from: Intel or AMD. This choice will definitely dictate which motherboard you can use, but may also influence the memory solution. Both the Intel Core and AMD Ryzen Series feature processors that are built for different needs and budgets. The smaller numbers are for entry-level and budget gamers, whereas the big numbers are about elite-tier performance with matching price tags. Check out this table for more details. 

Entry-levelCore i3 / i5Ryzen 5
Mainstream GamingCore i5 / i7Ryzen 7
EliteCore i9Ryzen 9
Xeon W-Series
Ryzen Threadripper


The RAM, or Random Access Memory, is your gaming PC’s short-term memory. This is where cache information is kept. Therefore, you need lightning-fast memory solutions with substantial capacities to keep everything running smoothly. Typically, 16GB to 32GB is ideal for gaming, whereas bumping up to 64GB or even 128GB and beyond is better for heavy-duty content creation and digital rendering. General rule of thumb: the more intensive your workload, the more RAM you’ll need. Currently, we use two standards of memory, DDR4 and DDR5. The latter is the latest standard which will eventually replace the former, but plenty of hardware is still utilising DDR4. If your budget is a little tighter, then opting for DDR4 is a good way to save without sacrificing performance. Also, be sure to check which standards your motherboard supports and which your RAM modules are – they need to match!

One other thing to consider when purchasing RAM is overclocking. If you’re using an AMD Ryzen 7000-based build, then look for modules with AMD EXPO. It allows you to easily overclock your RAM. For most other RAM kits, you can use either Intel XMP or DOCP for fine-tuning your memory’s performance. Check out our dedicated blog to learn more. 


Getting to the juicy stuff – your graphics card. Also known as a GPU, this is the piece of kit that renders your games, creative applications, and images. The major players are NVIDIA and AMD, but Intel has their own line of GPUs, too. Each is equipped with technologies to optimise gameplay, so that you can play at high resolutions and frame rates. It’s all about that immersive gaming. Fan favourites are real time ray tracing, which accurately replicates realistic light patterns, and upscaling technologies which improve resolutions (DLSS for NVIDIA, FSR for AMD, and XeSS for Intel). Whether you opt for an NVIDIA, AMD, or Intel graphics card isn’t going to have a major impact on the rest of your hardware, save for getting a PC case big enough to house them. (Those RTX 4090s are chonky bois!) It’s entirely down to your preference. 

What does need to be considered, much like with CPUs, is the performance you need from your GPU and the budget you have to play with. The following table details how each brand tiers their graphics cards. 

Entry LevelRTX 3050 / 3050 Ti / 3060

Now you need somewhere to store all your games, files, and even your operating system. There are two main types of storage drives, the traditional hard disk drive (HDD) and newer solid state drive (SSD). HDDs generally have high capacities for lower price points, as they are a well-established technology. However, with their moving parts and slower read/write speeds, they aren’t great for storing programs. That said, their high multi-terabyte capacities make them ideal for storing files, media, photos, and more. SSDs utilise faster NAND technology with integrated memory chips, so they are less likely to get damaged and corrupt your files whilst providing lightning-fast read and write speeds. This makes them great for storing games, applications, and operating systems, letting you take full advantage of reduced loading and boot times. The drawback here is they are still relatively new and much more expensive per byte. 

This will only improve with time, but your budget, for now, may require a combination of drives. We personally recommend opting for both drives. Use the SSD for the operating system, plus any programs or games you access regularly. The HDD should then be used to hold your expansive media library.

Of course, the most important part of your gaming PC isn’t the glamorous graphics card or processing powerhouse CPU. It’s the PSU, or power supply unit, for without it, nothing will turn on. The PSU you choose will depend on your PC case size, the power demands of your hardware, and what generation of tech you are using. Standard PC cases are generally compatible with ATX form factor power supplies, whereas SFF (small form factor) cases accommodate SFX or SFX-L PSUs. There is some wiggle room on that, and the PC case product or manufacturer page will state which size power supply they can host. 

Next, power demands. The more power hungry your hardware, the higher the wattage needs to be. The general rule of thumb when working out what wattage you need is to work out how much power your components use and then double it. That way you have headroom for overclocking and upgrades. Our helpful wattage calculator can figure it all out for you. What’s more, you need to make sure your PSU has the right connectors. For example, the NVIDIA RTX 40 Series GPUs need a dedicated 12VHPWR cable or adapter. It’s recommended you opt for an ATX 3.0 power supply, which you can read about here

Finally, power supply units are rated by efficiency. This is the 80 PLUS certification, stating how efficient the PSU is at half-load. 80% is the minimum efficiency to earn this rating, hence 80 PLUS. The PSU’s 80 PLUS rating will easily be identifiable on the product or manufacturer page. Each rating has a corresponding metal; the more precious, the better the efficiency. For example, a Bronze rating means the PSU is 85% efficient at half load, whereas a Platinum rating is 90% at half load.

PC Case:

The last essential is your PC case. A large deciding factor for your case will be an aesthetic one – do you want it to be white? With a tempered glass panel? Integrated RGB? All important decisions. But the first choice should always be the size or form factor. All the common sizes offer a variety of colours, accessories, and features, so you’re never not going to be spoiled for choice. The common form factors are Mini-ITX, Micro-ATX, ATX or mid-tower, and full tower. You can also get cube and specialist cases. Just be mindful when choosing a case, and make sure that it will accommodate all of your hardware. For example, a Mini-ITX case won’t house larger components such as an ATX motherboard. It’s super important to do your research before diving straight in.

Advanced Components

But wait, there’s even more. Take a quick sip and a breather, then we’ll head onto cooling, add-ons, and operating systems. 


First of all, I would like to stress that cooling is essential. It only falls into the advanced section because different gaming PCs will call for different degrees of cooling performance. If your gaming PC’s workload is going to be light, then air-cooling will suffice, whereas a hench powerhouse will need a fully custom water-cooling loop. Mainstream gaming will fall somewhere in the middle with all-in-one (AIO) water-cooling solutions.

Air vs Water Cooling: What’s the Difference?

Cooling in itself can be a rabbit hole to fall down, but we have a nifty guide that details where and when each can be used.

Operating System:

The operating system, or OS, is the interface you use to control your PC. Microsoft Windows, macOS, and Linux are all popular operating systems. Windows is the most commonly used on gaming PCs, with Windows 11 being the current standard, though Windows 10 is still widely used.

Add-ons cover a wide range of accessories, that goes from case modding to sound cards, drive cages to capture cards. These additions entirely depend on what you want from your gaming PC. Taking the capture card for example, they are a helpful tool for streamers but would offer no benefit to someone who does not live stream. Add-ons cover a wide range of accessories, that goes from case modding to sound cards, drive cages to capture cards, and beyond!

Tools of the Trade 

Whilst many PC cases boast a “tool-less” design, we cannot put our gaming PCs together with our bare hands. Tools are required. Most commonly needed are the following tools: 

  • A Phillips head and flat head screwdriver: Most of the components will need screwing into place, as will case side panels once everything is installed. The supplied screws on your hardware may differ in size, so it’s wise to keep a variety of screwdriver bits to hand. Also, don’t use power tools! These screws don’t require that much force and they may end up damaging your hardware. 
  • Cable ties: Cable ties are a godsend for managing your cables. With these nifty little things, you can group cables together to make routing them around your case much neater. Everybody loves a good bit of cable management! If you want to take it to the next level, check out Kolink’s range of cable management products here
  • Pliers: Pliers are useful to have on hand in case any screws or the motherboard stand-offs are too tight to undo. They are also super handy if a screw or small implement falls somewhere too small for your hand to reach in – ie, behind the motherboard tray. More advanced use could be bending back any modifications you’ve made. 
  • Wire cutter: Wire cutters are needed for trimming your cable ties down to size. It’s all about keeping your case as neat as possible! 

You could have these lying around your home, but you can purchase tools that have been designed for building PCs. These often include grounding mats to work upon and specialised devices that have been crafted for niche needs.

One of the best things about desktop PCs is their upgradability. Found a new love in video editing and need a bump in RAM capacity? Easy peasy. Plus, when certain components get old and tired, instead of buying entirely new you can make spot upgrades. The only time this could get tricky is jumping up to the next generation of processors. As previously stated, motherboards don’t necessarily have cross-generation support.  

This is where our upgrade bundles come in. If you want to take the guesswork out of moving onto the next generation of gaming hardware, then our 8Pack approved gaming bundles are the way forward. 

Upgrade Bundles:

These bundles are overclocked and ready to rock. Each contains the necessary components to easily transition you to the latest generation of gaming hardware. Here’s a breakdown of what these bundles typically contain: 

8Pack Elite Tier ASUS AMD Ryzen 9 Bundle
  • CPU: The star of the show, these bundles contain 14th Gen Intel, AMD Ryzen 7000, or even AMD Ryzen Threadripper processors.  They have been overclocked by 8Pack to provide optimised performance. All you have to do is select the bundle with the CPU model that best suits your needs. 
  • Motherboard: The chosen motherboard will have the chipset and socket to support your chosen CPU, along with a suite of gaming-tuned features.  
  • RAM: Giving you a little bit of choice, the RAM capacity can be configured with these bundles. Offering DDR5 RAM as standard, you can choose between 32GB or 64GB memory kits. Whichever suits your needs best. Some bundles offer a wider range of choices, including RGB modules. 
  • CPU Cooler: Finally, you have a choice of AIO CPU coolers or water blocks, depending on the bundle. Each has been selected for their high-performance and matched to the CPU’s TDP, but you have a choice between brands and styles.
