GIGABYTE B550I AORUS PRO AX
GIGABYTE B550I AORUS PRO AX Specifications Review
GIGABYTE B550I AORUS PRO AX by GIGABYTE is a Mini-ITX form factor motherboard based on the mid-range B550I chipset and AM4 socket, providing a balanced set of features and connectivity. It is designed to support DDR4 memory, with 2 slots, a maximum capacity of 64 GB, and an overclocking speed of up to 5300 MHz. It features channels, a voltage of V and supports Error-Correcting Code (ECC) memory.
VRM Quality
The GIGABYTE B550I AORUS PRO AX comes with an entry-level VRM setup, delivering 90 A across 8 phases. Works best with CPUs in the ~65–105 W TDP range. Can technically run higher-TDP processors at stock, but will likely experience thermal throttling under sustained heavy loads. Suited for budget gaming, office PCs, and home builds without heavy CPU demands.
See the VRM Appropriate CPU Specification Table at the bottom of this page for recommended CPU options.
Expansion and Storage Overview
The GIGABYTE B550I AORUS PRO AX offers a simplified expansion and storage configuration with PCIe 4.0 support, meaning it uses PCI Express 4.0, fast enough for modern GPUs and high-speed NVMe SSDs. It also includes 1 x16 slot . These PCIe slots are used to connect expansion cards — with the x16 slots typically reserved for graphics cards, while x8, x4, and x1 slots are used for devices like capture cards, sound cards, or network adapters.
For storage, this motherboard provides 2 M.2 slots and 4 SATA ports. M.2 slots are high-speed connectors for modern NVMe SSDs, which are much faster than older storage, while SATA ports are used for traditional hard drives and 2.5-inch SSDs. Together, they allow you to mix fast primary storage with larger, more affordable drives for bulk data.
Connectivity Overview
This motherboard has essential connectivity features with wired Realtek® 2.5GbE LAN chip (2.5 Gbit/1 Gbit/100 Mbit) Ethernet wireless networking with the wireless Wi-Fi 6 Bluetooth 5 is included for wireless peripherals. USB connectivity covers basic needs. Please refer to the specification table for details.
For video output, this motherboard includes HDMI version 2.1 , DisplayPort version 1.4 . These video outputs are intended for integrated graphics and will only function if your CPU includes integrated GPU capabilities.
