Pro Tip: When choosing a GPU, consider not just raw performance but also features like ray tracing, upscaling technology (DLSS, FSR, XeSS), and driver stability. Also, make sure it will physically fit in your case!
Motherboard
The motherboard is the foundation that connects all your components. It determines what CPU you can use, how many storage devices you can connect, what ports are available, and your potential for future upgrades.
Key considerations when choosing a motherboard:
- Socket Type: Must match your CPU (LGA 1851 for Intel, AM5 for AMD)
- Chipset: Determines features like overclocking support and connectivity options
- Form Factor: ATX (standard), micro-ATX (compact), or mini-ITX (tiny)
- RAM Slots: Most have 4 slots, mini-ITX usually has 2
- Storage Connectors: Look for multiple M.2 slots and SATA ports
- VRM Quality: Important for stable power delivery, especially when overclocking
Memory (RAM)
RAM is your system's short-term memory, storing data that's actively being used. For gaming in 2025, 16GB is the absolute minimum, but I strongly recommend 32GB for future-proofing and multitasking.
Key RAM specifications:
- Capacity: 16GB (minimum), 32GB (recommended), 64GB+ (content creation/streaming)
- Speed: DDR5-5600 is the baseline, with DDR5-6000 to DDR5-7200 being the sweet spot
- Timings: Lower numbers are better (e.g., CL30 is faster than CL36)
- Configuration: Always use matched pairs in dual-channel mode for best performance
Storage
Storage is where your operating system, games, and files live. In 2025, NVMe SSDs are the standard for gaming PCs, offering incredible speed compared to traditional hard drives.
Storage recommendations:
- Boot Drive: 500GB-1TB NVMe SSD (Gen4 or Gen5)
- Game Library: 1-2TB additional SSD storage
- Mass Storage: 2-4TB HDD for media files and backups (optional)
Pro Tip: For your boot drive, prioritize reliability over raw speed. A high-quality Gen4 SSD will feel just as fast as a Gen5 SSD in most real-world scenarios, and it will likely be more reliable and affordable.
Power Supply (PSU)
The power supply is the heart of your system, converting wall power to the various voltages your components need. Never cheap out on your PSU—a poor-quality unit can damage your components or cause system instability.
PSU considerations:
- Wattage: Calculate your system's needs and add 20-30% headroom
- Efficiency Rating: 80 Plus Bronze (minimum), Gold (recommended), Platinum/Titanium (high-end)

- Warranty: Look for units with 7-10 year warranties from reputable brands
Case
The case houses all your components and affects both aesthetics and thermals. Key considerations include:
- Size Compatibility: Ensure it fits your motherboard, GPU, and CPU cooler
- Airflow: Look for mesh front panels and multiple fan mounts
- Build Quality: Good materials and thoughtful design make building easier
- Cable Management: Ample space behind the motherboard tray for clean builds
Ensuring Component Compatibility
One of the biggest challenges for first-time builders is ensuring all components work together. Nothing is worse than receiving all your parts only to find they don't fit or work together properly.
Key Compatibility Checks
CPU and Motherboard
The CPU socket on the motherboard must match your processor. In 2025:
- Intel 15th-gen CPUs use LGA 1851 socket
- AMD Ryzen 8000 series uses AM5 socket
Additionally, check that the motherboard chipset supports your CPU out of the box, or that it can be updated without a CPU installed (BIOS flashback feature).
RAM Compatibility
Ensure your RAM is the correct type (DDR5 for modern systems) and check the motherboard's QVL (Qualified Vendor List) for guaranteed compatibility. Also verify the physical size—some large CPU coolers may interfere with tall RAM modules.
GPU and Case
Modern GPUs can be massive. Check:
- Length clearance in your case
- Width/height if you plan to use vertical mounting
- That it won't interfere with other components like front-panel connectors
Cooler Compatibility
Whether using an air cooler or AIO liquid cooler:
- Check CPU socket compatibility
- Verify clearance with your case and RAM
- For AIOs, ensure radiator mounting locations in your case
Power Requirements
Use a PSU calculator to estimate your system's power needs. Make sure your PSU has the necessary connectors, particularly for high-end GPUs that may require multiple 8-pin or the new 12VHPWR connector.
Pro Tip: Use PCPartPicker.com to automatically check for compatibility issues. It's an invaluable tool that catches most common problems before you buy.
Step-by-Step Building Process
Now for the fun part—actually building your PC! Set aside 2-4 hours for your first build, work in a clean, well-lit area, and take your time. Remember: it's not a race.
Preparation
Before you start building:
- Clear a large, static-free workspace
- Gather all your components and tools
- Have a Phillips head screwdriver (magnetic tip preferred)
- Keep component boxes and packaging handy
- Consider an anti-static wrist strap, or regularly touch a grounded metal object
Install CPU
This is often the most nerve-wracking step, but it's simpler than it seems:
- Open the CPU socket lever on the motherboard
- Align the CPU with the socket (look for alignment markers)
- Gently place the CPU in the socket—it should drop in without force
- Close the socket lever to secure the CPU
Warning: Never force the CPU into the socket. If it doesn't drop in easily, check your alignment. Bent pins can be difficult or impossible to repair.
Install RAM
RAM installation is straightforward:
- Open the retention clips at both ends of the RAM slots
- Align the notch in the RAM module with the slot
- Press firmly on both ends until the clips snap into place
- For dual-channel configurations, use slots 2 and 4 first (check motherboard manual)
Pro Tip: If you're having trouble getting the RAM to click in, try installing one module at a time. Sometimes the motherboard can flex slightly, making installation difficult.
Install M.2 SSD
If you're using M.2 storage (which you should be):
- Locate the M.2 slot on your motherboard
- Remove the retention screw (don't lose it!)
- Insert the SSD at a 30-degree angle
- Press down and secure with the screw
- Some motherboards include a heatsink for the SSD—use it if available
Prepare Case
Before installing the motherboard:
- Remove both side panels
- Install the I/O shield that came with your motherboard
- Install standoffs if not pre-installed (align with your motherboard's form factor)
- Route necessary cables before motherboard installation
- Install any case fans according to your planned airflow configuration
Install Motherboard
With the CPU, RAM, and M.2 drive installed:
- Carefully lower the motherboard into the case, aligning with the I/O shield and standoffs
- Secure with screws—don't overtighten
- Connect front panel connectors (power switch, reset, USB, audio)
- Refer to your motherboard manual for the exact pin layout
Install Power Supply
PSU installation varies by case design:
- If modular, connect only the cables you need
- Position the PSU (usually at the bottom rear of the case)
- Secure with four screws
- Route cables behind the motherboard tray for clean management
Install CPU Cooler
Cooler installation varies greatly by model:
- If using thermal paste, apply a pea-sized amount to the center of the CPU
- Some coolers come with pre-applied paste—check first
- Follow the specific instructions for your cooler model
- Connect the fan cable to the CPU_FAN header on the motherboard
Pro Tip: For AIO liquid coolers, mount the radiator in a position where the tubes are at the bottom of the loop if possible. This prevents air bubbles from accumulating in the pump, extending its lifespan.
Install Graphics Card
The final major component:
- Remove the appropriate expansion slot covers from your case
- Open the PCIe slot retention clip on the motherboard
- Align the GPU with the slot and press firmly until it clicks
- Secure the GPU to the case with screws
- Connect the necessary power cables from your PSU
Cable Management
Good cable management improves airflow and aesthetics:
- Route cables behind the motherboard tray when possible
- Use zip ties or Velcro straps to bundle cables neatly
- Ensure no cables are obstructing fans or airflow paths
- Leave some slack for future upgrades or maintenance
Final Checks & First Boot
Before hitting the power button:
- Double-check all connections
- Ensure no tools or extra screws are inside the case
- Connect monitor, keyboard, and mouse
- Plug in the power cable and flip the PSU switch to "on"
- Press the power button on the case
If all goes well, you should see the motherboard logo and eventually be prompted to install an operating system.
Troubleshooting Common Issues
Even with careful planning, sometimes things don't go perfectly on the first try. Here are solutions to common problems first-time builders encounter:
No Power/No POST
If nothing happens when you press the power button:
- Check that the PSU is switched on and properly plugged in
- Verify the front panel connectors are correctly installed
- Ensure the 24-pin ATX and CPU power cables are fully seated
- Try a different power outlet
- Test the PSU with the paperclip test (consult PSU manual)
Power On But No Display
If the system powers on but you get no image:
- Ensure your monitor is connected to the GPU, not the motherboard
- Try a different display cable or monitor
- Reseat the GPU and power connectors
- Try each RAM stick individually in different slots
- Check for motherboard diagnostic LEDs or error codes
System Randomly Crashes or Restarts
If your system is unstable:
- Update BIOS to the latest version
- Check that all power connectors are secure
- Test RAM with MemTest86
- Monitor temperatures to rule out overheating
- Ensure you're not overloading your PSU
Slow Performance
If your system isn't performing as expected:
- Check that RAM is running at its rated speed in BIOS
- Ensure your monitor is set to its highest refresh rate
- Install latest GPU drivers from manufacturer's website
- Check that your SSD is properly installed and recognized
- Run benchmarks to compare with similar systems
Pro Tip: When troubleshooting, change only one variable at a time. This makes it easier to identify the specific cause of any issues.
