The Rise of Small Form Factor PCs
As an experienced IT professional, I’ve seen a significant shift in the desktop computing landscape over the past decade. The days of bulky, tower-style cases dominating our workspaces are rapidly coming to an end. Instead, the rise of small form factor (SFF) PCs has ushered in a new era of compact, powerful, and space-efficient computing solutions.
The driving force behind this trend is the remarkable progress in PC component miniaturization. Modern CPUs, GPUs, and other essential hardware have become increasingly efficient and compact, allowing us to pack impressive performance into surprisingly small enclosures. This has opened up a world of possibilities for users who value desk space, portability, or simply a cleaner, more streamlined aesthetic.
In this comprehensive guide, we’ll explore the ins and outs of building a compact AMD-based gaming PC in an ITX form factor. We’ll dive into the key considerations, best practices, and essential components to help you create a powerful, space-saving system that can handle the most demanding games and applications.
Choosing the Right ITX Case
The foundation of any successful SFF build is the case itself. When it comes to ITX form factor PCs, there are several distinct styles to consider, each with its own unique advantages and trade-offs.
The Halftower: These cases maintain a relatively compact footprint while still offering ample space for standard-sized components. Halftower designs, such as the Cougar QBX Kaze or Fractal Design Node 304, can accommodate full-size CPU coolers and GPUs without significant compromises. However, they do tend to be slightly larger than other SFF options, often in the 10-15 liter range.
The Pizzabox: As the name suggests, these cases have a flat, wide profile that positions components horizontally. This design provides direct airflow access to the CPU and GPU, but can present challenges for cooling due to the limited vertical space. The Loque Ghost S1 and Dan A4-SFX are examples of high-quality pizzabox-style ITX cases.
The Cube: Cube-style cases, such as the Lazer3D LZ7, orient the motherboard at the bottom and the GPU vertically. This unique layout can offer improved GPU cooling, as the graphics card’s fans have direct access to fresh air. However, CPU cooling may be more difficult to manage in this configuration.
The Sandwich: Sandwich-style cases, like the Loque Ghost S1 or NCASE M1, strike an excellent balance between component layout and cooling efficiency. By sandwiching the motherboard between the GPU and CPU, these designs facilitate optimal airflow and thermal management, making them a popular choice for high-performance SFF builds.
When selecting your ITX case, be sure to carefully consider the maximum GPU length, CPU cooler height, and other dimensional constraints to ensure compatibility with your chosen components. Measuring the available space in your desired case is crucial to avoid any fitment issues during the build process.
Selecting the Right AMD CPU and Motherboard
In the world of compact gaming PCs, AMD’s Ryzen processors have become the go-to choice for many enthusiasts. Their impressive performance, power efficiency, and thermal characteristics make them an excellent fit for the space-constrained environment of an ITX build.
For a balanced, high-performance gaming system, we recommend considering the Ryzen 5 5600X or Ryzen 7 5800X. These CPUs offer excellent single-threaded performance for gaming, while also providing ample multi-core horsepower for productivity tasks, content creation, and more. The Ryzen 5 5600X, in particular, represents an outstanding value proposition, delivering near-flagship-level gaming performance at a very reasonable price point.
When it comes to the motherboard, your options in the ITX form factor are more limited, but there are still some excellent choices available. Look for a quality B550 or X570 motherboard that provides the features and connectivity you need, such as fast M.2 SSD slots, sufficient PCIe lanes, and robust power delivery for overclocking (if that’s your thing).
Some top-tier ITX motherboard recommendations include the Asus ROG Strix B550-I Gaming, the Gigabyte Aorus Pro AX, and the ASRock X570 Phantom Gaming-ITX/TB3. These boards not only offer the necessary functionality, but also often include useful extras like built-in Wi-Fi, Bluetooth, and high-quality audio solutions.
Selecting the Right GPU for Your ITX Build
Choosing the right graphics card for your compact gaming PC is a delicate balancing act. You’ll need to prioritize both performance and physical size to ensure your chosen GPU fits seamlessly within the constraints of your ITX case.
Fortunately, modern GPU manufacturers have made great strides in delivering powerful, yet compact, graphics card options. NVIDIA’s RTX 30-series lineup, in particular, includes several models that are well-suited for SFF builds.
If your budget allows, the RTX 3080 Ti Founders Edition is an excellent choice. This powerhouse GPU offers phenomenal 4K gaming performance in a relatively compact form factor, measuring just 285mm in length. Alternatively, the RTX 3070 Ti or RTX 3080 (non-Ti) Founders Editions are also viable options that can deliver outstanding 1440p or 4K gaming experiences, while fitting comfortably into most ITX cases.
For those on a tighter budget, AMD’s Radeon RX 6800 XT or RX 6800 are worth considering. These cards provide impressive performance that can rival NVIDIA’s offerings, and they often come in shorter, more compact variants that are well-suited for SFF builds.
Whichever GPU you ultimately choose, be sure to carefully cross-reference the dimensions against the maximum GPU length specified for your selected ITX case. This will ensure a seamless, hassle-free installation process.
Cooling and Power Considerations
Cooling is a critical aspect of any SFF PC build, as the compact nature of these systems can present unique thermal challenges. Fortunately, there are several strategies and components you can leverage to ensure your compact gaming rig stays cool and stable under load.
For the CPU, we recommend opting for a high-quality low-profile air cooler, such as the Noctua NH-L12S or the Thermalright AXP-100 Ryman. These compact coolers are designed to fit within the tight confines of an ITX case, while still providing excellent heat dissipation. Alternatively, you can explore the option of a small-form-factor liquid cooler, which can offer impressive cooling performance in a compact package.
When it comes to the graphics card, the cooling solution is often less of a concern, as modern GPUs come equipped with highly efficient and well-designed cooling systems. However, it’s still essential to ensure your chosen GPU is compatible with the airflow and dimensions of your selected ITX case.
Lastly, don’t overlook the importance of a high-quality, SFX-sized power supply unit (PSU) for your compact gaming PC. Look for models that offer ample wattage to support your chosen CPU and GPU, while also maintaining a small physical footprint. Reputable brands like Corsair, EVGA, and Seasonic offer excellent SFX PSU options that are well-suited for ITX builds.
Building Your Compact AMD Gaming PC
Now that you’ve carefully considered the key components and design factors, it’s time to put together your compact AMD gaming PC. Remember, the assembly process for an ITX build may differ slightly from a traditional tower-style system, so it’s essential to plan ahead and follow best practices.
Start by carefully installing the CPU and CPU cooler, ensuring proper thermal paste application and secure mounting. Next, install the motherboard, taking care to route cables neatly and efficiently to maintain optimal airflow within the case.
When it comes to the GPU, pay close attention to the orientation and placement of the card, as some ITX cases may require a specific configuration to ensure proper cooling and clearance.
Power supply installation is also a critical step, as you’ll need to carefully manage the cables to avoid obstructing airflow or interfering with other components. Many SFX PSUs come with modular cables, which can greatly simplify this process.
Finally, don’t forget to install your storage drives, whether that’s a high-capacity SSD, an M.2 NVMe drive, or a combination of both. Careful cable management is key to maintaining a clean, organized, and well-cooled interior.
Throughout the build process, be mindful of the unique challenges posed by the compact nature of your ITX system. Take your time, refer to the manufacturer’s instructions, and don’t hesitate to consult online resources or reach out to the IT Fix community for additional guidance.
