Remember, putting a PC together is much more than just getting and putting a bunch of components together. You not only need to get the latest components, CPUs, SSDs, memory, graphics cards, Keyboards, and more, but you also need to make sure that the components are pricked correctly, and are compatible with each other. 

Now is a great time to build, with Intel’s 13th Gen CPUs offering excellent performance at a range of price points, as well as the cost of RAM becoming lower than ever before.

However, before putting it all together, you have to understand what kind of PC you want to build. Is keeping everything under budget a priority, or is 4K gaming the first thing on your list? Other things that you need to consider are the GPU, cooler and other components.

Once you have your price and budget in mind, you’re ready to start building your own gaming PC.

Step 1: Choose a case

Ahead of picking out anything else, choose a case for your system. This will dictate the size of your PC and will determine motherboard size, cooler compatibility, and airflow within your system. The most popular form factor is a mid-tower case such as the Lian Li Lancool II Mesh. Some cases have premium features that you might want, such as Cooler Master’s HAF 700 EVO, but these can cost a bomb.

If you wanted to build a compact, small gaming PC. You should expect to pay a bit more for your motherboard, and you might have to get creative with your component choice. Choosing a form factor is an essential step in how to build a gaming PC. So, be sure to pick wisely.

Once you’ve chosen your case, you can then move on to choosing components.

Step 2: Pick your components

Picking components can be really troublesome. If you are picking an Intel or AMD CPU, make sure that you are picking the right motherboard to go alongside it. Remember, choosing an RTX 4090 for your PC will mean very little if your CPU and Power Supply are not up to the task of running it.

Make a checklist of the following components:

  • CPU
  • GPU
  • Motherboard
  • RAM
  • Storage
  • PSU
  • CPU cooler

The main areas that will determine performance will be your CPU and GPU. While your motherboard sits as the beating heart, making sure that everything is working correctly. Some motherboards can offer premium features like more memory slots, or fancy USB-C headers, so be sure to choose wisely.

You should also look to pick up a PSU (Power Supply) that is able to run everything that you throw at it. Make sure you pick up a reputable brand’s PSU, as skimping out on this component can really throw you under the bus, and cause other parts to fail if it is not up to the task.

If you want to make sure that your build is going to go smoothly, we recommend that you prepare a small area for your parts and tools. Make sure you have a good screwdriver to hand, as you’ll need to make use of it during the build process.

You will also want to create a bootable OS image on a USB stick. You can grab one for Windows here. BE sure to select Windows 11 Installation Media.

Then, ensure that all of your parts arrive safely. Once it’s all arrived, and you have a small build area prepped, you can begin your gaming PC build in earnest.

Step 4: Installing the CPU

Firstly, take your motherboard out of its box, and place it upon the static sheet that arrives with it. Then, pop the motherboard and the static bag on top of the box. Now, we’ll want to begin prepping the motherboard.

The first thing that you’ll want to do is to place the CPU into the motherboard. Modern motherboards use an LGA system, which is a small lever that releases the latch so the CPU can be put into place. Pull it gently away from the socket to unlatch it. Once it’s been unlatched, take your CPU out of the box.

What you are looking for here is a small chip with gold contacts underneath. Hold the CPU by its edges, so as to not disturb the gold contacts. CPUs are very fragile. Then, you should see an arrow on your CPU, line this up with the socket on the motherboard, and gently place it into the socket.

Once it’s in, you can once again lower the retention layer, this can require some force, but you’re not doing anything wrong as long as it’s all lined up correctly.

Step 5: Installing your RAM


To slot in your RAM, you first need to identify the RAM slot on your motherboard, this is a long strip, with latches on either end. Using your motherboard manual, identify the primary slots. If you are installing more than one stick of RAM, make sure you choose the right slots for it to run in a slightly speedier dual-channel mode. This is usually inferred by a “A2 and B2” designation. Then, make sure that the slots are unlatched.

Now, unbox your RAM, and identify where the small notch lies on your RAM stick and motherboard. Then, it’s as simple as applying some pressure until you hear a small click. This will signify that the RAM is placed correctly. Make sure to double-check that both ends are correctly seated on each stick of RAM you are installing. Once they are all slotted in, you can move to the next step.

Step 6: Installing an M.2 NVMe SSD

Most modern systems now use an M.2 NVMe SSD drive, which looks like a little stick of gum. There should be a port on your motherboard to install this. Once you identify it, make sure you have one of those smaller screws that you might have included in the box for your motherboard. Then slot the M.2 NVMe SSD into your system. It should prop itself up at an angle, if done right. Then, gently press down until it aligns with the screw-hole on your motherboard, and safely screw it into place.

Step 7: Install your CPU cooler (Air)

Now, if you have picked an Air cooler for your system, this is the best place to install it. If you are using an aftermarket cooler. Make sure you follow the instructions provided to install it into your system. If you are using an AIO water cooler, you should wait until a little bit later to do this step. Don’t forget your thermal paste. Be sure to hook up your fans while doing this, too.

We recommend that you use a blob sized to a grain of rice in the middle of the CPU for good coverage.

Step 8: Place your motherboard into the case

Now that your motherboard is all prepared, you want to unbox your case and lay it flat. If your motherboard has a detached IO shield, then you’ll want to place this now. If not, you can safely ignore it for now.

Many cases come with preinstalled standoffs. However, if your chosen case does not have these, place them aligned to the holes. Then, align the standoffs with your motherboard. Once fully aligned, begin to screw the motherboard into the standoffs. This should align with the holes on your motherboard, too. BE sure to screw in opposite ends first, to securely align the motherboard in place. Continue this until you have securely fastened the motherboard to your case.

Then, you will want to hook up your front IO cables, this might require a USB header or two, in addition to small front-panel pins. Consult your motherboard’s manual to understand where this is, and what pins need to be where.

Step 9: Prepare your Power Supply


Next, you should unbox your power supply. If you have a modular power supply, you want to ensure you have the motherboard, CPU, and GPU cables attached. Then, place the Power supply into your system. Now, carefully route the cables into their intended positions. Your 24-pin motherboard cable should be placed around the right of the motherboard, the CPU connectors on the top left, and the GPU cable routed to the underside.

Then, connect the PSU cables for your motherboard and CPU to your system.

Step 10: Install your CPU cooler (AIO)

If you have an all-in-one water cooler for your CPU, this is the time you should install it. Firstly, we’d recommend installing the fans and radiator into your case. This can be in several positions. Then carefully follow your AIO’s manual to understand how the fans align with the AIO in your case.

Then, you’ll want to place any brackets onto your motherboard. Then, use some thermal paste on top of your CPU. We recommend a blob the size of a grain of rice. Then, plop the AIO onto your CPU and securely fasten it.

You’ll want to take some time here to ensure that all cables required are plugged into your motherboard, this might include fan headers, USB headers, or SATA power. If you require SATA power, just attach a SATA cable to your PSU and hook it all up. If you’re unsure of where to place or identify any motherboard headers, consult the manual.

Step 11: Install your GPU


To install your GPU, make sure there are no obstructions on your case. This might include some brackets on the back that need to be removed. Depending on the size of your graphics card, this can be anywhere between two to four slots.

Then, align the PCIe connector on your GPU with the notches on your motherboard. Push it in until you hear a satisfying click. If it’s not working, make sure you are level to the socket.

Once the GPU has clicked into place, you want to screw in the bracket for the slots. It’s worth pushing your GPU up slightly while fastening these, as you can attain minimal GPU sag for doing so.

Once it’s all screwed into place, hook up the PSU cables we routed earlier and plug them into your GPU. If you have a GPU that uses Nvidia’s new 12VHPWR connector, ensure that you leave around 3.5mm of space before bending it.

If you want to install extra fans, this is your chance, look for the header on your PC in order to hook them all up. If you have ARGB headers, make sure you use the correct header, as plugging it into the wrong one could cause your RGB goodness to short out.

Step 13: Test boot

Motherboard Case

Hook up the power cable, and switch your PSU on, next, hook your GPU display ports up to your monitor. Then, press the power button. If you have done this correctly, then your PC should spring to life, and you’ll be greeted with a BIOS screen. If you’ve reached this point, you can now install an OS such as Windows if you hook up a keyboard.

If it’s not turned on, retrace your steps to the motherboard pinouts for the power button. If it runs, but you are not posting, you may need to look into a hardware issue. Some motherboards have blinking LEDs or codes which indicate what is going wrong. Failing that. Retrace and redo all of your steps. If it still doesn’t work, then you may be facing a power issue.

Step 14: Install Windows & drivers

Next, using your bootable Windows drive, install the OS. It’s pretty self-explanatory. Then, once you are in Windows, ensure that you install any software related to your GPU driver. Then any fan control or RGB software will also come in handy, depending on what you have purchased.
