Introduction
Last year, AMD released the Ryzen 3000 series desktop processors in one of the most monumental hardware launches of the modern era. This final step completed the Red brand's ascent back into the forefront of the desktop processor market that began with the launch of the first generation of Ryzen CPUs.
With the Ryzen 3000 launch came the AMD X570 chipset. Featuring PCIe 4.0 support, X570 was an impressive leap from generations past. It was also hot, with motherboards often including chipset cooling fans, and, more significantly, expensive. The high cost of the chipset increased the average cost of X570 motherboards considerably over previous generations.
While AMD has done a great job of maintaining motherboard compatibility with new generation processors, none of the previous-generation AM4 motherboards featured official PCIe 4.0 support, not even from the storage and PCIe controlled by PCIe 4.0 compatible CPUs. Enter B550, the more value-oriented little brother of X570. While the B550 chipset is PCIe 3.0 only, B550 motherboards support PCIe 4.0 from the CPU to the primary PCIe slot as well as the primary M.2 slot (dependent on a PCIe 4.0 ready CPU).
The Gigabyte B550M AORUS Pro features a 10+3 VRM design, Q-Flash Plus, and a formidable VRM thermal solution. With a surprisingly fleshed-out feature set and an attractively low price, the Gigabyte B550M AORUS Pro has a lot going for it, so let's dive in and see if the performance lives up to the potential!

Packaging and Contents
The front of the Gigabyte B550M AORUS Pro box features a dark background dominated by the AORUS logo. "B550M AORUS Pro Gaming Motherboard" is printed in white and orange on the left side, with the brand badging on the right.
The back of the box has all the highlights: a top-down shot of the board, several panels detailing prominent features, a shot of the rear I/O, and the specifications list. The box design is well executed and matches the board perfectly.
The accessories are standard, even sparse. Notably absent is any kind of rear I/O shield because the shield is integrated into the board.
The full list of accessories includes:
- Manual and support DVD
- AORUS badge
- 2x SATA 6 Gb/s cables
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.
