Gigabyte B550M K WIFI6E AM4 Micro-ATX Motherboard Wi-Fi 6E
The Gigabyte B550M K WIFI6E is a micro-ATX motherboard for AMD Ryzen 3000, 4000 and 5000 series processors, built for compact builds that need PCIe 4.0 storage and Wi-Fi 6E connectivity. It suits builders looking for a smaller form factor without sacrificing modern features or gaming and workstation performance.
Why this product
Wi-Fi 6E and Gigabit Ethernet
Dual connectivity with Wi-Fi 6E 802.11ax wireless and 1 Gbps Gigabit Ethernet. The Wi-Fi antenna uses EZ-Plug design for quick installation.
PCIe 4.0 M.2 storage
Two NVMe slots — one PCIe 4.0 x4 from the CPU and one PCIe 3.0 x2 from the chipset — with support for NVMe or SATA mode and RAID.
Smart Fan 6 with FAN STOP
Five temperature sensors across the board feed data to adaptive fan control that can halt fan spin at low load, reducing noise.
Anti-sulfur and surge protection
Ultra Durable components include sulfur-resistant resistors and anti-surge circuitry for long-term stability in varied environments.
- ChipsetAMD B550
- Form FactorMicro-ATX
- Memory Slots4 x DDR4 DIMM
- M.2 Connectors2 (1 x PCIe 4.0, 1 x PCIe 3.0)
- WirelessWi-Fi 6E 802.11ax

- SKUGIG-1811
- EAN4719331880811
- Fits AMD Ryzen 5000, 5000 G, 4000 G and 3000, 3000 G series processors in AM4 socket.
- Accepts DDR4 memory (non-ECC or ECC unbuffered) in 4 DIMM slots, up to 4733 MHz overclocked.
- Supports NVMe M.2 drives in PCIe 4.0 or 3.0, and SATA M.2 SSDs on the CPU slot.
- Micro-ATX form factor fits smaller cases but not full-size ATX enclosures.
- Intel processors and LGA sockets are not compatible — this is AMD-only.
Best for
- Compact gaming and workstation builds that need PCIe 4.0 NVMe speed without a full-size motherboard footprint.
- Builders wanting Wi-Fi 6E and wired Gigabit Ethernet in a single micro-ATX board.
- Users who value thermal management and low-noise operation with Smart Fan 6 and multiple temperature sensors.
- Systems where anti-sulfur and anti-surge durability matter — industrial, lab or harsh-environment setups.
Trade-offs
- Full-size ATX case builders — micro-ATX is narrower and will not fill a large chassis.
- Quad-channel or high-capacity RAM builds — this board maxes out at 4 DDR4 DIMMs.
- Heavy multi-GPU systems — only one PCIe x16 slot is available (the second slot is x1).

With NVMe PCIe 4.0*/3.0 x4 and PCIe 3.0 x2 M.2 connectors onboard, GIGABYTE Motherboards bring users to experience NVMe mode or SATA mode connectivity for M.2 SSD devices. Delivering up to 64 Gb/s data transfer speed, the dual M.2 connectors design provides an ideal storage solution while also supporting in RAID modes.
Gigabit Ethernet (GbE) LAN provides significantly faster data transfer speeds of up to 1 Gbps, which is ten times faster than traditional 100 Mbps Fast Ethernet, enabling smoother streaming, faster file transfers.
GIGABYTE motherboards feature an audio noise guard that essentially separates the board's sensitive analog audio components from potential noise pollution at the PCB level.
B550 motherboards feature solid plated ATX 12V 8pin power connectors for offering stable power supply while CPU overloading.
Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function. By equipping resistors with an Anti-Sulfur Design GIGABYTE gives Ultra Durable Motherboards a whole new meaning.
GIGABYTE motherboards also feature special anti-surge IC that protect your motherboard, helping to ensure longevity of your system components.
