Build Your First Gaming Computer in 20 Steps or Less!

Building your first gaming computer in 20 steps or less can be an exciting and rewarding experience. Here’s a step-by-step guide to help you through the process:

1. Planning and Choosing Components for your First Gaming Computer

Step 1: Define Your Budget and Requirements

  • Determine how much you’re willing to spend.

  • Decide what games and applications you plan to run to identify necessary specifications.

  • Use PC Part Picker:

Step 2: Select Your Components

  • CPU (Processor): Choose a powerful CPU suitable for gaming (e.g., Intel i5/i7/i9, AMD Ryzen 5/7/9).

CPU, Processor
  • GPU (Graphics Card): Select a dedicated graphics card (e.g., NVIDIA GeForce RTX, AMD Radeon).

  • Motherboard: Ensure compatibility with your CPU and has necessary features (e.g., PCIe slots, USB ports).

  • RAM (Memory): Typically 16GB is recommended for gaming.

  • Storage: Get an SSD for faster load times (256GB or higher) and consider adding an HDD for additional storage.

  • Power Supply Unit (PSU): Ensure it has enough wattage to support all components (e.g., 650W or higher).

  • Case: Choose a case that fits your components and has good airflow.

  • Cooling System: Consider aftermarket CPU coolers or additional case fans if necessary.

2. Gathering Tools and Preparing Workspace for Your First Gaming Computer

Step 3: Gather Necessary Tools

Computer hardware screwdriver
  • Phillips-head screwdriver.

  • Anti-static wrist strap (to prevent static damage to components).

  • Zip ties for cable management.

  • Thermal paste (if not pre-applied on the CPU cooler).

Step 4: Prepare Your Workspace

  • Work on a clean, flat surface.

  • Ensure you have good lighting.

  • Have all your components and tools within reach.

3. Building the Gaming Computer in 20 Steps or Less

Step 5: Install the CPU

  • Open the CPU socket on the motherboard.

  • Align the CPU with the socket and gently place it in.

  • Secure the CPU with the socket arm.

Step 6: Install the CPU Cooler

  • Apply thermal paste if necessary (a small pea-sized amount).

  • Attach the cooler according to the manufacturer’s instructions.

  • Connect the cooler’s fan to the motherboard.

Step 7: Install RAM

  • Open the RAM slots on the motherboard.

  • Align the RAM sticks with the slots and press down firmly until they click into place.

Step 8: Install the Motherboard

  • Place the I/O shield in the case.

  • Align the motherboard with the standoff screws in the case and secure it with screws.

Step 9: Install the Power Supply Unit (PSU)

  • Place the PSU in the designated area of the case.

  • Secure it with screws.

  • Route the necessary power cables to the motherboard, CPU, and GPU.

Step 10: Install the Storage

  • Mount the SSD and HDD in their respective bays.

  • Connect them to the motherboard using SATA cables and to the PSU with power cables.

Step 11: Install the Graphics Card (GPU)

  • Remove the corresponding expansion slot covers on the case.

  • Insert the GPU into the PCIe slot on the motherboard.

  • Secure the GPU with screws and connect the power cables from the PSU.

4. Final Steps

Step 12: Connect Case Cables

  • Connect the case’s front panel connectors (power button, USB ports, audio jacks) to the motherboard.

  • Connect case fans to the motherboard or PSU.

Step 13: Cable Management

  • Use zip ties to bundle and organize cables.

  • Ensure cables do not obstruct airflow.

Step 14: Double-Check Connections

  • Verify all components are securely installed.

  • Check all power and data connections.

5. Initial Setup and Testing

Step 15: Power On the PC

  • Connect the monitor, keyboard, and mouse.

  • Plug in the power cable and turn on the PSU.

  • Press the power button on the case.

Step 16: Enter BIOS/UEFI

  • Press the appropriate key (e.g., DEL, F2) during startup to enter BIOS/UEFI.

  • Check if all components (CPU, RAM, storage) are recognized.

  • Adjust settings if necessary (e.g., boot order).

Step 17: Install Operating System

  • Insert the installation media (USB drive) with your OS (e.g., Windows, Linux).

  • Follow the on-screen instructions to install the OS.

Step 18: Install Drivers and Updates

  • Install the latest drivers for your GPU, motherboard, and other components.

  • Update your OS to the latest version.

Step 19: Install Games and Software

  • Install your favorite games and necessary software.

  • Configure settings and start enjoying your new gaming PC!


  • Take your time and don’t rush through the process.

  • Refer to manuals and online guides specific to your components.

  • Join online communities for additional support and advice.

By following these steps, you’ll be well on your way to building your first gaming computer. Enjoy the experience and happy gaming!
