GIGABYTE B550 EAGLE Motherboard - ATX - AMD B550 Socket

GIGABYTE B550 EAGLE Motherboard - ATX - AMD B550 Socket arrives as a robust ATX motherboard designed for Socket AM4 processors and fully compatible with AMD Ryzen 3000, 4000 and 5000 Series CPUs.

This GIGABYTE B550 EAGLE supports DDR4-SDRAM across four DIMM slots in dual-channel mode, offering up to 128 GB total memory (up to 32 GB per slot) and official support for speeds up to 3200 MHz. Both ECC and non‑ECC unbuffered memory are supported, making it suitable for performance desktops and light workstation tasks.

Storage flexibility is a highlight on the B550 EAGLE, with two M.2 slots (one PCIe 4.0 x4 capable, one PCIe 3.0) plus four SATA III connectors for up to six drives in total and RAID 0/1/10 support for data protection or speed. The board also exposes PCIe expansion with one PCIe x16 (Gen4) slot and four PCIe x1 (Gen3) slots for add‑in cards.

Rear connectivity includes multiple USB options—USB 2.0, USB 3.2 Gen1 Type‑A and Type‑C, and a USB 3.2 Gen2 Type‑A port—plus a single Gigabit Ethernet (Realtek RTL8111H) and HDMI 2.1 for integrated graphics output with up to 4096 x 2160 resolution and HDCP support. Onboard audio is handled by the Realtek ALC897 codec offering 7.1 channels.

Built for reliable cooling and system monitoring, the board features passive cooling, three chassis fan connectors, two CPU fan connectors, a water pump header, multiple temperature and voltage monitoring points and five RGB LED headers for lighting control. Power delivery includes a 24‑pin ATX connector and a single 8‑pin EPS connector.

The UEFI AMI BIOS (128 Mbit) provides a modern firmware interface with Clear CMOS jumper and wide OS support including Windows 10 x64 and Windows 11 x64. The motherboard is ATX form factor (305 x 244 mm), finished in a dark brown color, and backed by a 3‑year warranty.

Use cases include high‑performance gaming builds using Ryzen 5000 CPUs with PCIe 4.0 NVMe storage, content creation desktops requiring multiple drives and high memory capacity, or reliable office/workstation systems that benefit from RAID and ECC compatibility. Included accessories such as screws and a CR2032 BIOS battery simplify installation.

Key selling points: AM4 support for Ryzen 3000/4000/5000, PCIe 4.0 M.2 support, 128 GB DDR4 capacity, extensive fan and RGB headers, RAID support and a comprehensive set of USB and display ports—making the GIGABYTE B550 EAGLE an excellent choice for versatile ATX builds.
