GIGABYTE B550M K WIFI6E Micro-ATX AMD B550 AM4 DDR4 Motherboard, Wi-Fi 6E, Bluetooth 5.3, PCIe 4.0 | GA-B550M-K-WF6E

Wi-Fi 6E and Bluetooth 5.3 Built In

GIGABYTE fits a MediaTek Wi-Fi 6E MT7902 module supporting 2.4, 5 and 6 GHz with 160MHz channels, plus Bluetooth 5.3 for controllers, headsets and keyboards. The module is 1T1R, a single antenna stream, so in our assessment it is a convenience feature for browsing, streaming and online games rather than a replacement for a LAN cable when moving large files.

To use the 6 GHz band you need a Wi-Fi 6E or Wi-Fi 7 router; on older routers the board still connects on 2.4 and 5 GHz.

PCIe 4.0 Graphics and Storage with Ryzen 5000

With a Ryzen 5000 or 3000 processor, the x16 slot and the first M.2 socket (M2A_CPU) run at PCIe 4.0. With G-Series APUs such as the Ryzen 5 5600G or 5600GE, both drop to PCIe 3.0, which is a processor limit rather than a board limit.

The second M.2 socket (M2B_SB) is PCIe 3.0 x2 from the chipset, fine for a game library or bulk storage drive but slower than the CPU-connected socket. Four SATA ports with RAID 0, 1 and 10 cover hard drives and 2.5-inch SSDs.

DDR4 Up to 128GB

Four DIMM slots take up to 128GB of dual-channel DDR4, with official speeds to 3200 MT/s and XMP overclocked speeds up to 4733 MT/s depending on the processor and modules. Two matched sticks in the recommended slots are the sensible start; the other two slots leave room to upgrade later.

Display Outputs for APU Builds

DisplayPort 1.4 (up to 5120 x 2880 at 60 Hz) and HDMI 2.1 (up to 4096 x 2160 at 60 Hz) work with Ryzen processors that have integrated graphics. Ryzen 5000 non-G CPUs such as the 5600 or 5600X have no graphics, so those builds need a graphics card.

Philippine Buyer Perspective

Our Take

This is a practical board for AM4 builds where wireless matters more than overclocking features. In many homes the router sits in a different room from the PC, and built-in Wi-Fi 6E with Bluetooth saves both a slot and a USB port.

Plan cooling around its one system fan header: a case with three or more fans needs a fan hub or splitter, or fans that daisy-chain. For heavy overclocking or high-end Ryzen 9 builds, a higher-tier B550 board with more fan headers and overclocking features is the better match; for Ryzen 5 and Ryzen 7 gaming and office builds, this board covers what most buyers use.
