Best Mini-ITX Motherboards 2016: Top Compact Options for PC Builders

Mini-ITX motherboards pack a lot of power into a tiny package. These small form factor boards are perfect for compact builds where space is tight.

We love how they let you create powerful PCs that fit almost anywhere, from living room entertainment centers to small desks.

When shopping for a mini-ITX motherboard, pay close attention to expansion options. Since space is limited, you’ll have fewer PCIe slots and RAM slots than larger boards.

CPU socket type matters too, as it determines which processors will work with your board. Other key features to check are built-in Wi-Fi, USB ports, and whether the board supports overclocking.

In 2016, the ASUS ROG Strix Z270I Gaming stood out as our top pick among mini-ITX motherboards. It offered great performance for gamers in a tiny package.

We tested dozens of mini-ITX boards to find the ones that deliver the best combination of features, reliability, and value for different needs.

GIGABYTE A520I AC Mini-ITX

The GIGABYTE A520I AC offers impressive value for budget-minded builders seeking a reliable AMD Ryzen mini-ITX motherboard with good connectivity options.

Pros

• Excellent compatibility with 3rd Gen Ryzen CPUs
• Solid build quality with optimized VRM cooling
• Great connectivity including WiFi, Bluetooth and multiple display outputs

Cons

• Limited to PCIe 3.0 speeds
• Only one M.2 slot for storage
• No USB-C ports on rear panel

We recently built a compact PC using this motherboard, and it performed better than expected for its price point.

The GIGABYTE A520I AC handled our Ryzen 5 3600 with ease, maintaining stable temperatures even during extended gaming sessions. The VRM heatsink does its job well, preventing thermal throttling issues we’ve seen on other budget boards.

Setting up was mostly hassle-free. The BIOS is intuitive and the Q-Flash Plus feature saved us time when updating the firmware.

We didn’t need to install a CPU first – just plugged in a USB drive with the new BIOS file, pressed the button, and it updated automatically. This feature alone makes it worth considering for beginners.

Connectivity is surprisingly good for a budget mini-ITX board. The Intel WiFi and Bluetooth work reliably, and we appreciate having three display outputs for APU builds.

The board supports up to 64GB of DDR4 RAM, which is plenty for most users. During our testing, enabling XMP profiles was simple, and our 3200MHz memory ran without issues.

The single M.2 slot limits expansion options, but that’s typical for this form factor and price range. We used a 1TB NVMe drive which performed well with the PCIe 3.0 interface. For additional storage, the SATA ports work fine with traditional SSDs.

Audio quality from the ALC887 codec is adequate for everyday use, though audiophiles might want to use external solutions. The Gigabit LAN performed reliably during our online gaming sessions with no noticeable issues.

For a 2016-era mini-ITX board, this GIGABYTE model has aged surprisingly well. Its support for newer Ryzen CPUs means it can still be the foundation of a capable compact system today.

• Might require BIOS update for newest CPUs

We recently got our hands on the GIGABYTE B850I AORUS PRO, and we’re impressed by how much they’ve packed into this tiny board.

Despite its small footprint, it feels surprisingly substantial – almost dense when you pick it up. The build quality is top-notch with a sleek matte black finish that looks great in any case.

Setting up our test system was straightforward. The EZ-Latch feature for the PCIe slot made installing our graphics card much easier than traditional mechanisms.

We particularly appreciated the thoughtful placement of headers and connectors, which helped minimize cable management headaches in our compact build.

The thermal solution really stands out in real-world use. During our testing, the VRM stayed remarkably cool even under heavy loads. The active cooling on one of the M.2 slots is a nice touch, especially when using faster PCIe 5.0 SSDs that tend to run hot. We noticed the tiny fan is nearly silent during normal operation.

Connectivity is another strong point. With WiFi 7 and 2.5GbE networking, our downloads were lightning fast.

The rear I/O panel offers plenty of USB ports including USB-C, which we found convenient for our peripherals and external devices. The board supports up to 128GB of DDR5 RAM, giving us plenty of headroom for future upgrades.

BIOS navigation feels intuitive and responsive. We had no issues tweaking memory timings or adjusting power settings.

The board played nicely with our Ryzen processor right out of the box, though we always recommend checking for the latest BIOS updates for optimal compatibility.

GIGABYTE A620I AX Mini-ITX

The GIGABYTE A620I AX offers solid value for builders seeking a compact AM5 motherboard with good connectivity despite some BIOS update challenges.
