- Read motherboard manual thoroughly
Installation Order (2-3 hours)
Step 1: Install CPU
- Open motherboard CPU socket
- Align CPU with socket (look for triangle marker)
- Gently place CPU (no force needed)
- Close retention arm
Step 2: Install RAM
- Open retention clips
- Align notch on RAM with socket
- Press firmly until clips snap into place
- Install in slots 2 and 4 for dual channel
Step 3: Install M.2 SSD
- Remove M.2 heatsink (if included)
- Insert SSD at 30-degree angle
- Press down and secure with screw
- Replace heatsink
Step 4: Install I/O Shield
- Press firmly into case rear opening
- Ensure all tabs click into place
Step 5: Install Motherboard
- Install standoffs in case
- Align motherboard with I/O shield
- Secure with screws (don’t overtighten)
Step 6: Install Power Supply
- Position PSU (fan facing down/out)
- Secure with four screws
- Route cables through grommets
Step 7: Install CPU Cooler
- Apply thermal paste (rice grain size)
- Mount cooler per instructions
- Connect fan header to CPU_FAN
Step 8: Install Graphics Card

First Boot (30 minutes)
Pre-Power Checklist:
- All power connections secure
- RAM clicked in fully
- GPU power connected
- Monitor connected to GPU (not motherboard)
- PSU switch on
Initial POST:
- Press power button
- Enter BIOS (usually Delete or F2)
- Check all components detected
- Enable XMP/DOCP for RAM
- Set boot priority
- Save and exit
Install Operating System:
- Insert Windows USB installer
- Follow installation prompts
- Install motherboard drivers
- Install GPU drivers
- Run Windows Update
Common Mistakes to Avoid
Forgetting I/O Shield Install before motherboard goes in. Removing motherboard later is frustrating.
Improper RAM Installation Use slots 2 and 4 first for dual channel. Check motherboard manual.
Monitor Connected to Motherboard Always connect to GPU for gaming. Motherboard video won’t use your graphics card.
Insufficient PSU Power Calculate total system wattage and add 20% headroom. Don’t cheap out here.
Poor Cable Management Take time to route cables properly. Improves airflow and looks professional.
Not Updating BIOS/Drivers Always install latest chipset, GPU, and motherboard drivers for best performance.
Performance Optimization Tips
Enable XMP/DOCP Activates your RAM’s rated speed in BIOS. Significant performance gain.
Adjust Fan Curves Create custom curves balancing temperature and noise in BIOS or software.
Monitor Temperatures Use HWInfo64 to track temps. CPU under 85°C and GPU under 80°C under load is ideal.
Optimize Windows Disable startup programs, enable Game Mode, update graphics drivers regularly.
Overclocking (Advanced) Modern CPUs and GPUs boost automatically. Manual overclocking offers minimal gains for most users.
