Step-by-Step Assembly Guide

Building Your Gaming PC

Prepare Your Workspace

Clear a large, well-lit table. Ground yourself by touching unpainted metal before handling components. Organize your screws and tools. Read the motherboard manual's quick-start guide.

Install CPU

Open the CPU socket lever on your motherboard. Align the golden triangle on the CPU with the triangle on the socket. Gently place the CPU - it should drop in without force. Close the retention lever.

Install RAM

Check your motherboard manual for optimal slots (usually A2 and B2 for two sticks). Open the retention clips. Align the notch on the RAM with the slot. Press firmly until both clips snap into place.

Install M.2 SSD

Remove the M.2 heatsink if present. Insert the SSD at a 30-degree angle into the slot. Press down and secure with the included screw. Replace the heatsink.

Install CPU Cooler

Apply a pea-sized amount of thermal paste to the center of the CPU (if not pre-applied). Attach the cooler mounting brackets. Place the cooler and tighten screws in an X pattern. Connect the fan header to CPU_FAN.

Install Motherboard in Case

Install the I/O shield (if separate). Place standoffs in the correct positions for your motherboard size. Lower the motherboard onto the standoffs, aligning with I/O shield. Secure with all included screws.

Install Power Supply

If modular, connect only the cables you need. Mount the PSU with the fan facing down (if case has bottom ventilation). Secure with included screws. Route cables through the back of the case.

Connect Power Cables

Connect the 24-pin ATX power to the motherboard. Connect the 8-pin CPU power (top-left of motherboard). These cables only fit one way - don't force them.

Install Graphics Card

Remove the appropriate PCIe slot covers from the case. Open the PCIe slot retention clip. Insert the GPU firmly until the clip snaps. Secure with case screws. Connect PCIe power cables from the PSU.

Connect Front Panel

Connect front panel connectors (power button, reset, LEDs) to the motherboard header. Connect front USB 3.0 and USB-C headers. Connect HD Audio for front headphone/mic jacks. Consult your motherboard manual for exact pinout.

Install Case Fans

Mount case fans (typically 2-3 intake front, 1 exhaust rear). Connect to motherboard fan headers or a fan hub. Ensure positive pressure (more intake than exhaust) to reduce dust.

Final Checks

Double-check all power connections. Ensure RAM is fully seated. Verify GPU is secure. Check that CPU cooler is making good contact. Manage cables for airflow.

Cable Management Tips

Good cable management improves airflow, aesthetics, and makes future upgrades easier.

Pro Tips for Clean Cables

Route cables behind the motherboard tray whenever possible. Use velcro ties instead of zip ties for easy adjustments. Plan your cable routes before connecting everything.

Essential Techniques:

Use cable routing holes - Run cables through the cutouts in your case
Bundle similar cables - Group power cables together with ties
Hide excess length - Tuck extra cable length behind the motherboard tray
Front panel cables first - These are hardest to reach, connect them early
Custom cables (optional) - Sleeved extension cables add a premium look

BIOS Setup and Configuration

On first boot, your PC will enter the BIOS. Here's what to configure:

Enable XMP/EXPO - This runs your RAM at advertised speeds
Set boot priority - USB drive first for Windows installation
Enable Resizable BAR - Improves GPU performance
Check temperatures - CPU should idle at 30-45°C
Update BIOS - Check manufacturer website for the latest version

XMP/EXPO is Critical

Without enabling XMP (Intel) or EXPO (AMD), your RAM runs at default 4800MHz instead of the rated speed. This can cost you 10-15% gaming performance.

Windows Installation

Installing Windows 11

Create Installation Media

Download the Windows 11 Media Creation Tool on another PC. Create a bootable USB drive (8GB minimum). This takes 10-20 minutes.

Boot from USB

Insert the USB drive into your new PC. Press the BIOS boot menu key (usually F12, F11, or Del) during startup. Select the USB drive.

Install Windows

Select your language and keyboard layout. Click "Install Now." Enter your product key or select "I don't have a product key" to activate later. Choose "Custom: Install Windows only."

Select Drive

Select your NVMe SSD. If you see multiple partitions, delete them all to start fresh. Select the unallocated space and click Next.

Complete Setup

Windows will install and restart several times. Create your user account. Skip optional Microsoft services if you prefer privacy. Reach the desktop.

Driver Installation

After Windows installation, install drivers in this order:

Chipset drivers - From AMD or Intel website
GPU drivers - From NVIDIA GeForce Experience or AMD Adrenalin
Motherboard drivers - Audio, LAN, WiFi from manufacturer
Peripheral drivers - Mouse, keyboard, headset software

Info

Windows Update handles most basic drivers automatically. However, always install GPU drivers directly from NVIDIA or AMD for best gaming performance and features.
