Description
GIGABYTE B840M GAMING PLUS WIFI6E - Motherboard delivers a modern micro-ATX platform for gamers and creators, built around the AMD B840 chipset and compatible with Socket AM5 processors from the AMD Ryzen 7000/8000/9000 series.
This motherboard supports DDR5 memory across four DIMM slots in dual-channel mode and accommodates up to 256 GB of unbuffered non-ECC RAM with supported clock speeds up to 8200 MHz, making it ideal for memory-hungry applications and high-refresh gaming rigs.
Storage flexibility is strong with two M.2 PCIe 4.0 slots (one 2580 and one 2280), four SATA III ports and support for RAID 0, 1, 5 and 10, allowing fast NVMe boot drives combined with ample HDD capacity for bulk storage.
Connectivity is comprehensive for a micro-ATX board: USB 3.2 Gen2 Type-A, USB 3.2 Gen1 Type-A and Type-C, multiple USB 2.0 ports, a gigabit Ethernet port (Realtek RTL8111H), HDMI 2.1 and two DisplayPort 1.4 outputs, plus 7.1-channel audio driven by the Realtek ALC897 codec.
Wireless and modern peripherals are well supported with onboard Wi‑Fi 6E (MediaTek MT7902) and Bluetooth 5.3, plus two external antenna jacks. Power and cooling headers include a 24‑pin ATX connector, an 8‑pin EPS, one CPU fan header and two chassis fan headers, along with robust PC health monitoring for fan, temperature, voltage and water cooling sensors.
In practical use, the GIGABYTE B840M GAMING PLUS WIFI6E is excellent for compact gaming builds, home content creation workstations, or a LAN-party rig that needs Wi‑Fi 6E and high-speed storage. Its passive cooling and micro‑ATX footprint suit small but powerful cases.
Additional selling points include HDMI 2.1 support up to 4096×2160, HDCP 2.3 compliance, UEFI AMI BIOS with 256 Mbit memory, multiple RGB headers (four) for system lighting, TPM connector for platform security and a three-year warranty for peace of mind.
