What do you need to build your own PC?<\/strong><\/h2>\n\n\n\n
Choosing components can be an arduous task, but choose carefully. Not all of the best components are compatible with each other, with size and form factor being major considerations. Always be mindful of component upgradability, wear and tear if you\u2019re choosing secondhand parts, port counts, and what you might need in the future that you haven\u2019t considered yet. The following are the basic, necessary components for a functional PC:<\/p>\n\n\n\n
1. Processor (CPU)<\/h3>\n\n\n\n
The right CPU<\/a> (central processing unit) for you depends entirely on your needs and budget. The more cores you have, generally, the more expensive your CPU will be. However, a CPU with more cores is more likely to age gracefully over a 6-core CPU, which may be reasonable for gaming now but will likely be far too outdated in the future to run triple-A games. Unlike the current choice of GPUs, which is basically a two-way street- you have a few brand options for central processing units for gaming<\/a>. <\/p>\n\n\n\n
Some budget-friendly central processing units may come with a stock cooler, but if not, or if you want the best experience, you\u2019ll want to opt for a 3rd party extra cooling component.<\/p>\n\n\n\n
2. Graphics Processing Unit (GPU) and graphics cards<\/h3>\n\n\n\n
For gamers, a GPU is the biggest part of your build, vital for the best possible performance and likely to be the most expensive portion of your build, unless you\u2019re looking to use your CPU\u2019s integrated GPU (not recommended). Modern-day graphics cards complete complex calculations, multitudes of them at a time and the amount of calculations has increased significantly since the early days of gaming, which is why it is essential to know what you\u2019re looking for and why when choosing a graphics card. <\/p>\n\n\n\n
3. Motherboard<\/h3>\n\n\n\n
There are three main motherboard sizes: ATX, micro-ATX, and mini-ATX. Considering the size of your case and space limitations is paramount when choosing your motherboard, since everything is connected to it. The ideal motherboard for you may have a variety of ports, memory slots for RAM, expansion slots for NVME and PCI, and SATA connectors for SSDs or HDDs. You also need to consider compatibility and the socket type your motherboard has to accommodate your CPU. A motherboard equipped with the wrong bracket type might set your build back a few days waiting for a new part, so ensure your PC comes fully equipped with the fixtures you need.<\/p>\n\n\n\n
4. Memory (RAM)<\/h3>\n\n\n\n
Ensuring fluid gameplay and multitasking. RAM (random-access memory)<\/a> is the short-term memory for running applications and is another important factor to consider when determining what you want to accomplish with your setup and how to future-proof it. Most systems nowadays require at least 16GB, however an upgrade to 32GB is going to keep you up and running for much longer.<\/p>\n\n\n\n
5. Storage (SSD vs HDD)<\/h3>\n\n\n\n
Optional long-term storage solutions for extra documents, photos and video storage. SSDs are physically more durable, faster, and more compact than HDDs, whilst HDDs have a longer lifespan and more storage for less expense. Find out more in our comprehensive guide to HDDs vs SSDs<\/a>. <\/p>\n\n\n\n
6. Power Supply (PSU)<\/h3>\n\n\n\n
The boring part, but still important: The Power Supply Unit (PSU) offers consistent power. Choosing the right power supply for your computer depends on the demands of your components: the size of your motherboard, your CPU\u2019s brand, socket, and model, the number and size of SSDs\/HDDs, which optical drive you have, and the brand and model of your GPU.<\/p>\n\n\n\n
7. PC Case<\/h3>\n\n\n\n
All components are held and protected by the case. You might choose to customise yours; if so, there are multiple options available in our PC builder. You may opt for engraved glass or non-standard colours, possibly from the VIVID range. Whatever your choice, consider ventilation, component sizes and where you want to store your tower when choosing between mid-size and mini<\/a> towers.<\/p>\n\n\n\n
8. Cooling (Air vs Liquid)<\/h3>\n\n\n\n
For cooling options, there\u2019s a variety of customisation options, from fan sizes and colours to RGB lighting and the colour of your liquid coolant. If you\u2019re opting for the full gamer rig and want RGB fans to match your cyber set-up, make sure to choose reversible fans and install them the correct way around so that air is being brought into the system and expelled correctly. Liquid cooling is optimal, but poor installation of all-in-one systems can be hugely problematic, so be sure you know what you\u2019re doing. Check out our guide on the differences between liquid cooling and AIO systems<\/a>.<\/p>\n\n\n\n
9. Tools and Accessories<\/h3>\n\n\n\n
Ensure your space is well-lit and suitable for an easy build experience. Generally, you\u2019ll need a couple of different sizes of Phillips screwdrivers for PC assembly, and you might also need zip-ties for proper cable management and just in case, really. Thermal paste is an absolute must: which one to pick and why it\u2019s important are key to your success. Do your research on thermal paste application or purchase thermal pads if you\u2019re unsure. You can also pick up a cleaning kit<\/a> for your screen, chassis and keyboard. Cleaning kits are not advised for use on internal components.<\/p>\n\n\n\n
10. Operating System and Software<\/h3>\n\n\n\n
If your chosen operating system is Windows<\/a>, it\u2019s a simple matter of purchasing the licensing option you want and installing it. There are other OS options out there, but they can be complex to install and manage and may not meet your software requirements.<\/p>\n\n\n\n
You\u2019ll also need to install your motherboard\u2019s and GPU\u2019s drivers and ensure they are up to date. This includes drivers for Wifi and Bluetooth. For extra protection, a good anti-virus software is always recommended. Our in-house custom-built and pre-built PCs and laptops come with 1 year of Norton antivirus, so you won\u2019t need to worry about shuffling free trials.Building a PC isn’t just the physical installation of parts, but the<\/p>\n\n\n\n
How Long Does It Take to Build a PC?<\/h2>\n\n\n\n
Your build time depends entirely on your experience, competence, parts, and how much patience you have. A thorough understanding of troubleshooting and building could save you tens of hours.<\/p>\n\n\n\n
- \n
- First-time builders, a lot can go wrong before you\u2019ve even started building. For a real beginner, build time can take up to 6 hours. However, if you reach the end of your build and encounter troubleshooting issues, you may need to disassemble and reassemble your entire rig to find the problem. Poor installation PC either now or later, so great care is warranted.<\/li>\n\n\n\n
- For an experienced builder, a custom build may take as little as a couple of hours, but even then, costly mistakes can be made.<\/li>\n\n\n\n
- In-house builders at CyberPowerPC overcome challenges with new component compatibility, and fixtures are built to high standards through expert handling backed by hundreds of hours of build experience. A pre-built PC can be delivered next-day<\/a>.<\/li>\n<\/ul>\n\n\n\n

Building a PC is more than the physical placement of parts, consider how air moves through your container and understand how the RAM slots you use affect performance to make the most of your expensive components.<\/figcaption><\/figure>\n\n\n\n Is it cheaper to build your own PC?<\/strong><\/h2>\n\n\n\n
You might be thinking: Is a custom gaming PC cheaper than a prebuilt PC? And that question entirely revolves around how much money you want to spend on your custom build. Depending on what parts you choose, it can at times be cheaper than a prebuild.
When it comes to building your own PC, you might think that you are saving money, but that isn\u2019t always the case. There are many hidden costs when building your own PC, including component costs. This can affect you in the long run if you don\u2019t know what you are choosing in terms of component compatibility, and it will have a huge impact on the total cost.
Other examples of hidden costs include tools and accessories, as well as other gear you need to put the PC together. It will cost you if you don\u2019t already have them in your roster.
Screwdrivers, anti-static gear, thermal paste, and other tools add up.<\/p>\n\n\n\nVoiding your Warranty<\/h2>\n\n\n\n
You are prone to mistakes when building a PC yourself as an amateur. It\u2019s not as easy as LEGO; common mistakes can be costly, including brute forcing parts into place, purchasing incompatible components, cooling systems, motherboards, CPUs, and GPUs all need to work in tandem, or you might install everything and end up with a faulty unit.<\/p>\n\n\n\n
What can void your part warranty?<\/h3>\n\n\n\n
Generally, misuse and neglect will void your part\u2019s warranty. You might be familiar with the dread of dropping your phone in the toilet or spilling coffee on your laptop keyboard; accidents happen. Incidents which void your warranty, particularly when it comes to your CPU and motherboard, are usually a lot more subtle. Incidents that may void your part warranties include:<\/p>\n\n\n\n
- \n
- thermal paste leak(s)<\/li>\n\n\n\n
- a bent pin half the size of your thumbnail\u00a0<\/li>\n\n\n\n
- Scratches and wear marking the part\u2019s reference legibility<\/li>\n\n\n\n
- Static charge<\/li>\n\n\n\n
- Power surges<\/li>\n\n\n\n
- Overheating<\/li>\n<\/ul>\n\n\n\n
You bare responsibility for your home build and, as a result, you shoulder the cost for most faults.<\/p>\n\n\n\n
An extremely common mistake that may not void your warranty but make you ineligible for a refund is buying incompatible components. This may result in failure to meet the conditions for a refund, and you\u2019re then facing the possibility of reselling the part(s) at a loss.<\/p>\n\n\n\n
A PC bought from a builder is entirely under warranty, depending on the manufacturer’s conditions. Whilst parts are under their own terms, and for some popular retailers, their warranties might last up to a year, CyberPowerPC warranty<\/a> options for parts last up to 3 years, and for labour costs, up to 5 years.
Pre-built PCs can offer you convenience and reliability. There\u2019s no need to worry about your own capabilities in understanding the complexities of PC components. <\/p>\n\n\n\nIf you crave extra customisation options, try ourEZ-PC<\/a> builder, which will also ensure that all the parts you are choosing are compatible with the rest of the PC. <\/p>\n\n\n\n
How to Build a PC, Step by Step<\/h2>\n\n\n\n
Step 1: Prepare Your Workspace<\/h3>\n\n\n\n
Take precautions to ensure there is nothing that might generate static on your desk, particularly anywhere near your motherboard. Static materials you\u2019ll want to avoid include nylon, wool, lead and cotton, whilst a wooden surface is basically neutral and ideal. You can also arm yourself with an anti-static wristband for extra protection; don\u2019t wear socks when walking on carpet, and occasionally touch the metal of your chassis to ground yourself. These measures aren\u2019t necessarily required, and there\u2019s scepticism around whether static is an issue at all for modern-day components.<\/p>\n\n\n\n
Step 2: Install the CPU, RAM, and Cooler<\/h3>\n\n\n\n
CPU installation depends on your motherboard’s socket. The CPU has gold prongs on the back; if bent, they could render your CPU non-functional, so be cautious during installation. Different CPUs and motherboards may install differently depending on your motherboard\u2019s sockets and your PC case.<\/p>\n\n\n\n
How to Install Your CPU<\/h4>\n\n\n\n
The majority of CPU chips are installed as follows: Begin by pressing down and raising the latch on the side of the CPU\u2019s square-shaped socket to release the retention bracket.
Raise the bracket to expose the socket, and align the small triangle at the top left of the bracket with the corresponding triangle on the CPU.
Gently place the CPU into the socket. Lower the bracket and push the latch down until it engages.<\/p>\n\n\n\nYou might hear the sound of pins bending, but as long as the CPU is properly in place, this is perfectly normal. Remove the cap, which should pop off automatically.<\/p>\n\n\n\n
How to Install RAM<\/h4>\n\n\n\n
Installing RAM is fairly simple. Line up the notch on the RAM stick with the corresponding slot\u2019s notch on your motherboard, press in and make sure the RAM clicks into place; otherwise, you may have troubleshooting issues later down the line. <\/p>\n\n\n\n
Step 3: Install the Motherboard in the Case<\/h3>\n\n\n\n
As stated earlier, your motherboard should be compatible with your PC chassis; the motherboard size compatibility is listed in your PC case’s specs. You may notice multiple prongs on the back of your PC case’s interior; these are known as standoffs. Your board should sit on these comfortably, ensuring no parts are compromised by the prongs, and conversely, your board isn\u2019t wobbly or loose. Your standoffs should screw in properly<\/p>\n\n\n\n
Step 4: Install Your PC\u2019s GPU in 6 steps<\/h3>\n\n\n\n
GPU is delicate and expensive these days, so take the same precautions throughout your build until your chassis is closed and your PC is bootable. Your GPU should have a tab which locks it in place in the PCIe slot.<\/p>\n\n\n\n
- \n
- Locate the top PCIe slot on your motherboard. You should typically use this top slot because it gives the GPU full, unrestricted access to bandwidth, yielding the best possible performance.<\/li>\n\n\n\n
- Line up your GPU to see which expansion slots on the back of your PC case need to be removed to fit the card’s input\/output ports.\u00a0<\/li>\n\n\n\n
- Unscrew these mesh covers and be sure to save the screws. Push the locking clip at the end of the motherboard’s PCIe slot back to fully open it, then align the GPU connector and press it in until it\u2019s securely latched.\u00a0<\/li>\n\n\n\n
- Once the GPU is installed, it will require its own power supply, which simply plugs into the GPU’s power connectors – some lower-end cards can pull power directly from the motherboard.\u00a0<\/li>\n\n\n\n
- You can now screw the GPU into where the mesh covers used to be to counteract any sag, using your saved screws.<\/li>\n<\/ol>\n\n\n\n
Note that once you\u2019re set up and your PC is bootable, you should plug your monitor cable (HDMI or DisplayPort) directly into the back of the graphics card, not the motherboard.<\/p>\n\n\n\n
Step 5: Install Storage and Power Supply<\/h3>\n\n\n\n
Your power supply should be helpfully labelled with pin slots of various sizes.<\/p>\n\n\n\n
Locate the PSU enclosure, which is usually situated at the bottom of the PC case<\/p>\n\n\n\n
Determine the correct orientation for your PSU exhaust fan, and slide the PSU into the enclosure<\/p>\n\n\n\n
Secure the PSU to the back of the case using the four provided screws. A helpful tip is to thread all four screws in loosely at first so you can easily adjust the alignment, and then tighten them all down securely so the unit doesn’t rattle.<\/p>\n\n\n\n
Feed your cables into their respective areas throughout your build to make sure they reach the associated components and push them in until they click. Do not use cables from previous PSUs or mix and match connectors. Use the cables that came with the new PSU.<\/p>\n\n\n\n
Step 6: Cable Management and Final Checks<\/h3>\n\n\n\n
Be mindful of airflow within your build. If you\u2019re using a closed chassis, be aware that your cooling system may be working overtime. The goal of fans and cooling systems is to move heat away from your components. Some processors may come with built-in cooling systems that could be dumping heat onto your motherboard. Ensure air moving through your rig can escape, keeping your build well-ventilated.<\/p>\n\n\n\n
If you\u2019re using an all-in-one cooler, make sure the pump is securely fastened to your CPU; otherwise, the plate won\u2019t make good contact with it, and your CPU might fry. At best, you won\u2019t be getting the most out of your cooling system.<\/p>\n\n\n\n
Step 7: First Boot and Setup<\/h3>\n\n\n\n
Now you can finally turn on your PC. Ensure your BIOS is up to date, or you may miss out on key features that improve CPU performance or RAM usage. Install Windows by following the OS’s instructions, then update drivers for your chosen CPU and GPU. Head to your GPU manufacturer’s website (Nvidia, AMD, or Intel) to download and install the latest graphics drivers so your new GPU works properly. Alternatively, you can download current drivers from curated resource pages like robeytech.com<\/a><\/p>\n\n\n\n
Should You Build Your Own Gaming PC or Buy One?<\/h2>\n\n\n\n
The choice to build your own PC or buy one depends on your motivation, ambition, and budget. Many of us love the idea of crafting our own bespoke options and that’s always an option for those with the time and money, but experts are also there to ensure a working product’s delivery whilst shouldering the risks.<\/p>\n\n\n\n
When Building Makes Sense<\/h3>\n\n\n\n
Building a PC makes sense for hobbyists, tinkerers, and upgraders. If you\u2019re planning to fit your own RAM upgrades or GPU, it helps to know your PC from the ground up.<\/p>\n\n\n\n
When a Pre-Built or Custom PC Is Better<\/h3>\n\n\n\n
A custom-built<\/a> and pre-built gaming PC<\/a> is fantastic for gamers who want:<\/p>\n\n\n\n
- \n
- Guaranteed compatibility<\/li>\n\n\n\n
- Professional cable management<\/li>\n\n\n\n
- Warranty and support<\/li>\n<\/ul>\n\n\n\n
Common problems with home builds can still happen after you\u2019ve fitted the whole PC. In a custom build, however, your main issue is ensuring you\u2019re making the most of your hardware and understanding what you\u2019re purchasing. Visit our pre-built gaming PC blog post<\/a> to learn everything you need to know before making your choice. <\/p>\n\n\n\n

Hidden Costs<\/strong><\/p>\n\n\n\n
So once you have all your components in the right places, how easy is it to get gaming? Firstly, your PC needs an operating system. You may choose Linux, a free operating system with a steep learning curve. If you prefer compatibility and practicality, Windows 11<\/a> Home is an easy install-and-go option and the preferred choice at \u00a3119.99.<\/p>\n\n\n\n
Peripherals<\/strong><\/p>\n\n\n\n
A home-built setup may cost you hours of time, and as a result of your hard work, you might want to treat yourself to a bespoke matching keyboard, mouse, headphones and speakers. Additionally, if you plan to record content on the PC, you\u2019ll want decent recording software or if you\u2019re trying to record from a console, a decent video capture card and possibly a sound interface for precise audio recording.<\/p>\n\n\n\n
Some streamers even opt for a second separate system for recording their stream.<\/p>\n\n\n\n
