Description

The Gigabyte B550M K is a Micro‑ATX motherboard built on the AMD B550 chipset with the AM4 socket. It supports AMD Ryzen™ 3000, 4000 G‑series, and 5000 (including G‑series) processors—offering excellent compatibility and future potential for Ryzen-based builds.


⚡ Power Design & Expansion

Powered by a robust 4+2-phase digital VRM design with low RDS(on) MOSFETs, this board delivers clean, efficient energy to the CPU. It features a reinforced PCIe 4.0 x16 slot for discrete graphics cards and a PCIe 3.0 x1 slot for additional expansion.


💾 Dual M.2 Storage & SATA

  • M.2_1 (CPU): Supports 2280-sized NVMe SSDs up to PCIe 4.0 x4 (or x2) depending on CPU.

  • M.2_2 (Chipset): Supports 2280 NVMe SSDs up to PCIe 3.0 x2.

  • SATA: Four SATA III 6 Gb/s ports with RAID 0/1/10 support—ideal for mixed SSD/HDD storage arrays.


🧠 Memory Support

Equipped with 4 DDR4 DIMM slots for up to 128 GB total memory. Max speeds reach DDR4‑4733 MHz (OC), with full support for both non‑ECC and ECC unbuffered RAM (depending on CPU), as well as XMP profiles.


🌐 Connectivity & USB

  • USB 3.2 Gen 1: Four ports on the rear panel and one internal header.

  • USB 2.0: Four rear plus one internal header.

  • Display: One HDMI and one DisplayPort output for processors with integrated Radeon graphics.

  • Networking: Realtek Gigabit Ethernet with bandwidth management tools for reduced latency.


🔊 Audio

Powered by a Realtek High Definition audio codec with Audio Noise Guard and high-end capacitors, this board provides clean, immersive sound with support for up to 7.1‑channel surround setups.


❄️ Cooling Features

Gigabyte’s Smart Fan 5 technology provides hybrid PWM/Voltage fan headers and multiple internal temperature sensors. With customizable fan curves and FAN STOP functionality, you can achieve optimal silent operation under low load.


🛡️ Durability – Ultra Durable Features

  • Solid-pin ATX 12 V connector for better power handling.

  • Anti-sulfur resistor design protects against corrosion and extends reliability in humid environments.

  • Glass-fabric PCB inhibits moisture damage.

  • Surge and ESD protection on LAN and other I/O to guard against electrical spikes.


🧩 Software & BIOS Utilities

Gigabyte’s software suite includes:

  • APP Center (with @BIOS, EasyTune, System Information Viewer, Smart Backup)

  • Q‑Flash for BIOS updates without installing a CPU or DRAM

  • Xpress Install to simplify driver and utility installs
