GIGABYTE B550 Aorus Pro V2 DDR4 AMD Motherboard

The GIGABYTE B550 Aorus Pro V2 is a full-size ATX motherboard (305 mm × 244 mm) built on the AMD B550 chipset for AMD Socket AM4. It is designed to support AMD Ryzen 5000 Series processors as well as 3rd Generation AMD Ryzen and 3rd Gen AMD Ryzen with Radeon Graphics processors. A BIOS update may be required to enable compatibility with the latest supported Ryzen generations; refer to GIGABYTE’s official compatibility list before purchasing. Power delivery is handled by a 12+2 phase Digital Twin Power Design using 50 A DrMOS components, paired with an advanced thermal solution that includes a Fins-Array VRM heatsink and a Direct-Touch Heatpipe. Two M.2 slots are present: M2A_CPU (CPU-direct) supports SATA and PCIe 4.0 x4 SSDs (PCIe 3.0 x4 with APU), while M2B_SB (chipset) supports PCIe 3.0 x4 SSDs. Both are protected by thermal guards. Six SATA 6 Gb/s ports with RAID 0/1/10 support round out the storage options. The board accommodates four DDR4 DIMM slots in dual-channel configuration, supporting up to 128 GB (32 GB per DIMM). Memory speeds range from DDR4-2133 up to DDR4-5100 OC (speed ceiling varies by processor generation). ECC Unbuffered and XMP modules are both supported. Connectivity highlights include a Realtek 2.5GbE LAN chip (2.5 Gbit/1 Gbit/100 Mbit) and an extensive USB layout: two USB 3.2 Gen 2 Type-A ports (rear), one USB 3.2 Gen 2 Type-C rear port, two USB 3.2 Gen 1 rear ports, six USB 2.0/1.1 rear ports, plus additional internal headers for front-panel USB-C and USB 3.2 Gen 1. An HDMI port on the rear panel supports up to 4096×2160 @ 60 Hz via integrated Radeon Graphics (APU required; HDMI 2.1, HDCP 2.3, HDR). Audio is powered by the Realtek ALC1220-VB codec with WIMA capacitors, rated at 120 dB SNR on the rear line-out, supporting 2/4/5.1/7.1-channel output and S/PDIF optical out. RGB FUSION 2.0 controls onboard LEDs, two addressable RGB headers, two standard RGB headers, and one CPU-cooler LED header. Smart Fan 5 provides hybrid fan control across multiple headers with water-cooling support. Q-Flash Plus allows BIOS updates without a CPU, RAM, or GPU installed—useful for day-one Ryzen 5000 preparation. The board ships with a pre-installed I/O shield for straightforward installation.
