Although buying a prebuilt gaming PC is more straightforward, some people want to be fully involved in building their computer. Building a gaming PC is time-consuming, but it is our specialty at iBUYPOWER.
With our beginner’s guide to building a gaming PC, you can learn more about the components that go into a PC and how to install them.
Guide to Building a Gaming PC: Why You Should Know How to Build a Gaming PC
When you know how to build a PC, you have the ultimate control over power, performance, and cost.
Some other benefits to building your PC include:
Cost Efficiency: You can purchase parts at a lower price by buying them on sale, reducing the overall cost of your PC build.
Familiarity with Parts: You know which parts are going into your PC, making it easier to upgrade, or if you decide you like one brand’s components over another.
Ultimate Customization: You can customize not just the components in your actual PC, but also its appearance. If there’s a certain theme or color scheme you’re going with, you can more easily create a build that reflects it.
More Upgrade Potential: Upgrading is easier when you only need to focus on specific components every few years, rather than buying a whole new system.
It can take time to fully understand how to build a custom PC, but it is all the more gratifying when you power it on for the first time.
Guide to Building a Gaming PC: The Components
Before diving into how to build a gaming PC, you need to set up and organize your workspace.
You’ll need:
A large table or surface that is clear and clutter-free (avoid building on the carpet).
A designated area for your small parts
A Phillips screwdriver (the kind that looks like a plus sign)
Thermal paste
You should also make sure you’re properly grounded, as static from your hands can damage the components or system. There are tools you can buy to help, but a quick touch to the unpainted metal in your case should let you know if you’re carrying a charge around.
Component #1: The CPU
The CPU handles all the PC’s data processing operations. On the motherboard, find the CPU socket (square metal slot with a metal arm next to it). After locating the socket, pull the arm away from the enclosure, and the frame should swing open. Now gently place the CPU in the socket. There will be a small arrow indicator on the chip to help guide correct alignment. Once the CPU is placed flat and in the correct orientation, lower the metal frame over the chip. It should fit firmly in place and lock the frame with the arm.
Component #2: The GPU
The GPU is responsible for graphics and video rendering. To install this part, locate the PCIe x 16 slot on the motherboard. This slot is at the back of the case to allow access to the GPUs I/O. When you locate the PCIe x 16 slot, insert the graphics card into the slot with the I/O ports facing the rear of the case. When the card is fully seated into the slot, secure it to the back of the case using the screw slots located along the back.
Component #3: The Memory
Computer memory (RAM) stores temporary data so that the processor can quickly access it. RAM slots typically come in 2- or 4-slot configurations. To install the memory, simply insert the RAM sticks into the RAM slots on the motherboard. There should be a small notch to guide the installation and orientation. Push firmly into the slot, and it should fit snugly.
Component #4: The Storage
Computer storage is where all the files are stored, and comes in 2 forms: solid-state drives (SSDs) and hard drives (HDDs). To install the storage drives, locate the drive bays. This location is where you mount the drives. Modern PC cases will accommodate both HDD and SSD storage. Usually, there is a metal bracket that designates the locations for inserting the drives. Secure them by screwing them into place, then attach the drives to the motherboard using SATA cables.
Component #5: The Power Supply
The power supply (PSU) delivers voltage to the computer. If your computer case is vertical, the power supply is likely at the bottom. Your PSU will produce hot air, so pay attention to the airflow and vent orientation of your case. You want cool airflow into the case and hot air to blow out. Attaching the power supply to the case is as simple as screwing in 4 screws.
Component #6: The Motherboard
The motherboard facilitates communication between the computer’s components. Place the motherboard with the I/O port facing the rear of the computer case. Motherboards typically have 9 mounting screw holes around the board, with one near the center. Apply the required screws to secure the board.
Guide to Building a Gaming PC: An Overview
Now that you know component-wise how to build a PC, here are step-by-step instructions on putting it together:
Install the PSU: Mount it with the fan facing forward for proper airflow. Secure it with screws, and identify the key cables (24-pin motherboard, CPU power, PCIe for GPU).
Prepare the Motherboard: Identify major components (CPU socket, RAM slots, PCIe slot, M.2 slot) and install parts on the motherboard before placing it in the case.
Install the CPU: Open the retention arm, align the CPU with the socket indicator, gently seat it, and lock it in place.
Apply Thermal Paste and Install CPU Cooler: Apply a pea-sized amount of thermal paste (if necessary), mount the cooler using an X-pattern, and ensure even pressure.
Install RAM: Align the RAM notch with the slot, using the recommended slots per the motherboard manual. Press until it clicks, and lock the latches.
Install Storage: Insert the SSD into the M.2 slot, securing it with the appropriate screw or standoff. Reinstall the heatsink if needed.
Mount the Motherboard in the Case: Install the I/O shield, align the motherboard with standoffs, lower it into place, and secure it evenly with screws.
Install the GPU: Remove the PCIe slot covers, then insert the GPU into the PCIe slot until it clicks. Secure it to the case.
Connect Cables and Manage Wiring: Connect PSU cables to the motherboard and GPU, attach case cables (power, USB, audio), connect fans, and tidy cables with zip ties or Velcro.
Install Fans: Ensure fans are positioned for proper airflow. Ensure cool air enters from the front or bottom, and warm air exits from the back or top.
Test the System: Plug in power and peripherals, turn on the PSU, and power up the system to confirm it boots. If there are any issues, you should troubleshoot and try again.
Finalize the Build: Refine cable management, reinstall case panels, install software, and start gaming.
