Board Layout

The B550M AORUS Pro utilizes a neutral color scheme that is easily matched with almost any system or build. The PCB is completely black, while the heatsinks and rear I/O cover are a dark gray.


The CPU socket is open enough for most air coolers.


There are two M.2 slots on the Gigabyte B550M AORUS Pro; one above the first PCIe x16 slot that supports PCIe 4.0 connectivity and another below the second PCIe x16 slot. The top slot features a full-coverage heatsink.


The Gigabyte B550M AORUS Pro has two PCI Express x16 slots, with the top being steel-reinforced and PCIe 4.0 compatible, as well as a PCI Express 3.0 x1 slot. The board has a total of four SATA 6 Gb/s ports on the side, angled 90 degrees from the board.


The Gigabyte B550M AORUS Pro has a surprisingly good I/O offering considering the price point and form factor.
