GIGABYTE B550I Aorus Pro AX Wifi AM4 DDR4 AMD Motherboard

The Gigabyte B550I Aorus Pro AX is a feature-rich Mini-ITX motherboard built on the AMD B550 chipset and designed for the AM4 socket. Despite its compact 17.0 cm x 17.0 cm footprint, it delivers a level of connectivity and power delivery more commonly associated with larger form factors, making it a compelling choice for small-form-factor PC builders who demand uncompromised performance. At the heart of its power delivery is a direct 8-phase digital VRM solution featuring 90A Smart Power Stage (SPS) components, backed by an advanced multi-layered heatsink and thermal baseplate to keep temperatures in check even under sustained loads. The board supports 3rd Generation AMD Ryzen processors as well as New Generation AMD Ryzen processors with Radeon Graphics via the AM4 socket. Memory support extends to two DDR4 DIMM slots with a combined maximum capacity of 64 GB (32 GB per DIMM). Native speeds begin at DDR4-2133 and reach DDR4-3200, with overclocked profiles supported up to DDR4-4866 for Ryzen 3rd Gen CPUs and DDR4-5300 for Ryzen APU platforms. Both ECC and non-ECC unbuffered modules are supported, along with XMP profiles for enthusiast memory kits. Storage is handled by two M.2 Socket 3 connectors (type 2260/2280). The primary slot (M2A_CPU) runs at up to PCIe 4.0 x4 speeds with 3rd Gen Ryzen CPUs, while the secondary slot (M2B_SB) on the back of the board supports PCIe 3.0 x4 via the chipset. Both M.2 slots feature Thermal Guard heatsinks. Four SATA 6 Gb/s ports support RAID 0, 1, and 10 configurations. Wireless connectivity is provided by an Intel Wi-Fi 6 AX200 module supporting 802.11ax on 2.4 GHz and 5 GHz dual-band with 2T2R antennas and Bluetooth 5. Wired networking uses a Realtek 2.5GbE LAN chip capable of 2.5 Gbit, 1 Gbit, and 100 Mbit operation. Audio is handled by the Realtek ALC1220-VB codec with Nichicon audio capacitors, delivering up to 7.1-channel High Definition audio with a rear 120 dB SNR rating on the line-out jack, which also supports DSD audio playback. The rear I/O panel includes one DisplayPort 1.4 (up to 5120×2880 @ 60 Hz), two HDMI 2.1 ports (up to 4096×2160 @ 60 Hz), one USB 3.2 Gen 2 Type-C port, one USB 3.2 Gen 2 Type-A port, four USB 3.2 Gen 1 Type-A ports, a Q-Flash Plus button for BIOS updates without a CPU or memory installed, one RJ-45 port, two SMA antenna connectors, and three audio jacks. RGB Fusion 2.0 support is provided via an onboard addressable LED (ARGB) header and a standard RGB LED strip header. Smart Fan 5 technology governs fan control through one CPU fan header and two system fan headers, all with FAN STOP capability. A TPM header (2×6 pin) is also present for security module compatibility.
