Building a Custom PC From Scratch: A Beginner’s Guide


Building a computer is a great way to understand its functions. Here is a detailed look at how to build a PC.

While there are plenty of excellent pre-built PCs available, nothing beats the fun of using the PC experience. Custom PCs always take an added advantage over pre-built PCs as they allow users to select according to their usages. While building a PC isn’t difficult, it can be daunting. Here’s a proven step-by-step guide to building a PC for those just starting out.

Parts needed to build a PC

  • Power supply unit (PSU)
  • Memory (RAM)
  • Motherboard
  • Central Processing Unit (CPU)
  • GPU (GPUs)
  • Storage
  • System cooling
  • Operating System (OS)
  • PC cabinet

Opening the cabinet
Processing the PC cabinet is the easiest phase. Initial setup is made easy by the instructions on the individual enclosure purchased. Place the enclosure on the work surface and remove the side panel. Remove anything hanging from the case – if it’s still attached, push it aside.

Connection components


  • Carefully remove the motherboard from its packaging and place it on a hard, flat, non-metallic surface.
  • The change in pin position is determined by the processor and motherboard used. Do not bend or touch the pins; instead, use a load lever to hold them in place.
  • Grab the CPU by its sides, position it appropriately with the colored triangle on the motherboard, and carefully insert it into the CPU socket. Press down firmly but gently on the holding arm until the CPU is firmly in place.

RAM and Storage:

  • Before inserting the RAM key, choose a higher frequency RAM for better performance. Press the plastic wings at each end down and out, then insert the sticks into the slot pointing up. Press firmly until the RAM snaps into the slot and the plastic wings lock into place.
  • Locate the M.2 storage slot on the motherboard and gently insert the M.2 SSD into it. It will protrude from the motherboard at a 35 degree angle when fully inserted. To secure the SSD, push it down and reinstall the small screw.

CPU cooler:

  • Thermal paste is required for all coolers. Each central unit has a stock cooler. In the stock cooler, the thermal paste is already applied. In the case of AIO cooler and water cooling system, the user should apply the thermal paste on the CPU.
  • Place the CPU cooler over the processor and gently push down. Any mounting brackets or bolts should line up with the CPU cooler base plate on the motherboard.

Installing the motherboard
After connecting all the parts needed to build a PC to the motherboard, place the motherboard inside the cabinet, carefully aligning its rear ports with the corresponding holes in the I/O shield. All that remains is to fix the motherboard using the screws supplied with the box.

Mounting the power supply
In most cases, the power supply is located on the back of the case. It can be found at the top, but it’s most commonly found at the bottom, where it can suck cold air under the chassis. It’s usually as simple as securing it with four screws to the back of the case once it’s in place. Next, connect the 24-pin power connection and the additional power connector on the motherboard.

Graphic card Facility

  • A PCI-Express (PCIe) x16 slot is used by modern graphics cards. Take the graphics card and gently slide it into the motherboard, making sure the ports are positioned at the back of the cabinet and the PCI-Express connector is pointing down.
  • After that, tighten the screws between the GPU and the case.

Installing Windows and Required Drivers
Turn on the power and press the power button on the front panel. If everything seems to be in order, complete the Windows installation process. This will require bios or drivers for proper operation. Download all necessary drivers from the manufacturer’s website.

Congratulations on completing the Custom PC Setup! The effort should not stop here. As hardware advances, the customization capabilities of a bespoke PC become virtually limitless. Users can change their configuration according to their demands and budget. By following this guide, anyone can build a PC.
