Gaming PC: How to build a gaming PC?

Building a gaming PC seems an intimidating task, but it is easier when divided into micro-steps. For building a gaming PC you need powerful hardware like CPU and GPU. Besides these components, other components are also equally important for better performance.

Before buying the components make sure to check the compatibility of one component with the other. Here is the list of components with the specification that you need to have for building a gaming PC:


Specs required for building gaming PC


  1. CPU (Central Processing Unit) of Gaming PC

  • The CPU must have at least 8 cores and 16 threads. Any processor with these specifications will give you a smooth experience.
  • Also, don’t forget to check the overclocking capability of the processor.


  1. Motherboard

  • The motherboard you buy must be compatible with the processor.
  • Memory support: at least 64GB, DDR4-4800MHz
  • Storage: M.2 SSD slot
  • USB port
  • Expansion slot
  • Video port
  • Network: LAN Ethernet, Wi-Fi


  1. Memory

  • RAM must be 16/32GB – DDR4 with a clock speed of above 3000MHz


  1. GPU (Graphics Processing Unit) of Gaming PC

  • The graphics card you select must be higher than 8GB. It will give you a smooth experience for rendering 120fps,1080p video quality.


  1. Storage

  • Get M.2 SSD of 512GB/1TB.
  • HDD of 1TB for storage


  1. Power Supply Unit (PSU)

  • The power supply of 750W is seen as the sweet spot for gaming PC. This will also support overclocking the CPU as most gamers do it to get a better experience during gaming.
  • Also important is to look for “80 plus” certification. This ensures 80 percent efficiency of the power supply.


  1. Cooling system for gaming PC

  • This is the most important component to take out the maximum output from the system.
  • Two types of cooling system
    • Air cooling
    • Liquid cooling
  • For best performance, liquid cooling is opted for and is a new technique of cooling system in the computer world but the air-cooling system will also get the task done.
  • Three cooling fans are necessary to maintain the temperature of the PC:
    • Component fan to pull out heat from heating components of the PC.
    • Exhaust fan to eliminate the hot air from the PC
    • Airflow fan to pull fresh air into the PC
    • All these fans are synced.


  1. Gaming Peripherals

  • The gaming mouse and keyboard, headphones having good quality sound, monitor with specification 120/144Hz at least 1080p picture quality.


  1. Gaming PC case

  • Can be transparent i.e., of glass to see through, or can be simple and cost-effective.


When all the components are here and ready to be assembled, we need tools to put the parts together and make the PC functional.

We need to have a proper workspace of insulating material (like dry wood) to prevent any accidental current flow, tools like a screwdriver, wire strap, wire cutter.


Now, since all the things are ready, we can proceed to assemble the components in the following steps:

Step by step process for Assembling the gaming PC

Step 1: Install the CPU on the motherboard of your gaming PC

  • Put motherboard on the workspace and find the CPU socket which is protected with a plastic cap.
  • Press the metal lever at the side of the CPU socket and gently put it to the side. This opens the socket tray.
  • Handle the CPU carefully, hold the CPU on the edge, don’t touch the pins of the CPU as this might cause dusting or oiling on the pins.


Step 2: Install M.2 SSD on the motherboard

  • Find M.2 slot on the motherboard.
  • Remove the screw.
  • Gently slide M.2 SSD into the slot. When the SSD is in place it will be slightly tilted. Push the SSD down and screw to lock it in place.


Step 3: Install CPU cooling on top of CPU

  • For the exact procedure to install the CPU cooler look in the manual. Some may have brackets pre-installed, and some don’t. Proceed according to manual.
  • Apply a bit of thermal paste on top of the CPU (if the CPU doesn’t have pre-applied paste).
  • Install the cooling fan on the top of the paste. The pressure from the fan while screwing it will spread the paste equally on the CPU.


Step 4: Install Memory (RAM) for your Gaming PC

  • There will be two or four slots for RAM.
  • If you are filling all of the slots you can simply unlock the slots and push the RAM in.
  • If all slots are not utilized then find the correct priority or configuration on the manual of the motherboard.


Step 5: Mount Power Supply in the case

  • Look at the case and find the spot for placing the PSU (usually present at the bottom towards the back)
  • The fan of the PSU should face outside the case through the vents.
  • If there is no vent on the case then face the fan upwards into the case keeping the space to flow air.
  • Attach PSU to the case using a screw that came with PSU.
  • Wiring of the cables from the PSU should be performed now (manage cables towards the components that need to get power from PSU).


Step 6: Install motherboard to the case

  • If your motherboard came without an I/O shield, there should be a rectangular metal sheet in the shape of the motherboard.
  • After the I/O shield is placed, you can install the motherboard. Make sure to check the cables are in the right spot then place and mount them on the motherboard on the case. Don’t drag the motherboard. Lift, hold and place in the correct position. Screw the motherboard on the place.
  • Connect the power supply to the motherboard as per the instruction in the manual. There are two connections, one with an 8 pin CPU connector towards the top and 24 pin connectors from the side.


Step 7: Install GPU for gaming PC

  • Find PCIe* x16 slot. It will be the longest.
  • If your motherboard has more than one PCIe* x16 slot, find the priority on the manual.
  • Provide enough breathing space for GPU.
  • Depending on the case, you may have to remove the I/O covers to accommodate GPU’s I/O and make it accessible to the exterior of the chassis.
  • Align GPU with rear retention bracket and self. Push gently into the PCIe* x16 slot till you hear a click sound.
  • When the GPU is in its position, screw it to the back of the case with a screw.


Step 8: Install storage

  • Look at your case to find a stack of bays of different sizes.
  • Storage generally comes in two sizes i.e., 2.5 inches (SSD and HDD) and 3.5 inches (HDD)
  • Most 3.5-inch bays can fit 2.5-inch drives.
  • Also, you can see a larger bay for larger drives such as optical drives.
  • If you have a tool-free bay, open the lever and you should be able to pull out the tray. Put your drive in the tray.
    • Screw the drive if necessary.
    • Slide the tray into the bay and listen to the click sound to confirm its placement.
  • If you don’t have a tool-free bay, you will see metal brackets with holes. To put the drive in the brackets, slide the drive and screw in its place. Use screw recommended in manual.
  • Connect motherboard to the power supply using SATA cable the comes with either drive or motherboard.


Step 9: Install operating system for your gaming PC

  • Connect peripherals like monitor, mouse, keyboard to the PC.
  • Prepare operating system (OS) in the USB flash drive.
  • Plugin the USB into the PC and turn on the PC.
  • Open the BIOS.
  • Make sure all the components are recognized by the system in BIOS.
  • Find the “Boot priority” and change it to flash drive to install the OS.
  • If you are using the SSD as a boot drive, you need to install OS on SSD and select SSD as “Boot priority”.
  • Restart your PC. PC will boot from USB (or SSD as per your selection) and the OS installer will be shown on the monitor.
  • Follow the OS installation process to finish.


Your gaming PC is ready to shoot games after installing games on the PC. Also, now you can advance your PC by overclocking your CPU.
