Model overview based on user reviews
The Gigabyte B550I AORUS PRO AX is a mini-ITX motherboard designed for gaming and overclocking, featuring an AMD AM4 socket and AMD B550 chipset. It offers a robust power delivery system with 8 power phases and reinforced connectors, making it suitable for handling even 16-core processors in overclocking scenarios. The board includes two DDR4 slots supporting up to 64GB of RAM with a maximum clock frequency of 4866 MHz. It provides a variety of connectivity options, including Wi-Fi 6, Bluetooth v5.0, HDMI 2.1, DisplayPort 1.4, and multiple USB ports. However, users have noted issues such as frequent Bluetooth disconnections and a somewhat unfriendly UEFI interface. Additionally, the placement of the CMOS reset jumper and the fin-shaped antenna design are seen as inconvenient. Despite these drawbacks, the board is praised for its excellent VRM cooling and easy BIOS flashing, making it a solid choice for users seeking a compact yet powerful motherboard.
Pros
Cons
The board has exactly everything that a regular user needs... I felt that some functions were missing. According to reviews, the board has one of the best overclocking potentials, if, of course, someone needs it. It handles even 16-core processors in overclocking perfectly. One of the best power delivery systems on boards of this class Very cool board, especially VRM Temperature sensor on VRM Easy BIOS flashing All connectors are reinforced No active cooling 3 fan ports are a bit too few no option to connect a thermal sensor to the board The CMOS reset jumper is in an inconvenient spot A fin-shaped antenna that needs to be placed on the table - not the best solution It's unclear what the engineers were thinking placing a large aluminum block over the m.2 slot, it may be a problem for very hot SSDs Not the most user-friendly UEFI interface, some settings are so deeply buried that you can't find them the first time  Vladimir: use Gigabyte B550I AORUS PRO AX less than month |
Like everyone else in this price category. The main and primary problem is that Bluetooth often disconnects. Updating the BIOS does not solve the issue. Aleksey Bezdomnikov: use Gigabyte B550I AORUS PRO AX few months |
