Gigabyte B840M Aorus Elite WiFi6E

Name: Gigabyte B840M Aorus Elite WiFi6E
Brand: Gigabyte
SKU: 58121

Manufacturer: Gigabyte

The Gigabyte B840M Aorus Elite WiFi6E is a Micro-ATX motherboard built around the AM5 socket, offering a compact 244 x 244 mm footprint suitable for space-conscious builds. It ships with dual BIOS for added resilience during firmware updates, supports Bluetooth 5.3, and includes an integrated Wi-Fi 6E adapter covering the 802.11n, ac, and ax standards across both 6 GHz and lower bands. A three-year warranty accompanies the board, and the easy-overclock feature gives users a straightforward path to pushing performance without deep BIOS configuration.

Memory support extends to four DDR5 slots across two channels, accommodating up to 256 GB at a native maximum of 5200 MHz or up to 8200 MHz when overclocked. Storage connectivity includes two M.2 sockets, four SATA 3 connectors, and full support for RAID 0, 1, 5, and 10 configurations. The rear I/O provides one USB 3.2 Gen 2 Type-A port, two USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 1 Type-C port, four USB 2.0 ports, HDMI 2.1, one DisplayPort output, and a single RJ45 port, while the single PCIe 4.0 x16 slot handles discrete graphics. On-board audio reaches 7.1 channels through three audio connectors, and six fan headers are available for thermal management.

Pros

Dual BIOS adds a layer of protection against failed firmware updates
Wi-Fi 6E support covers the full range from 802.11n through to the latest 6 GHz band standard
Four DDR5 slots with support for up to 256 GB and overclocked speeds reaching 8200 MHz offer substantial memory headroom
RAID 0, 1, 5, and 10 support gives meaningful flexibility for storage redundancy and performance configurations
Six fan headers allow for thorough thermal management across the system
Three-year warranty period provides solid long-term coverage

Cons

No PCIe 5.0 x16 slot limits compatibility with the fastest current-generation graphics and storage devices
Absence of USB 3.2 Gen 2 Type-C and USB 4 ports reduces high-speed connectivity options on the rear I/O
No S/PDIF Out port may be a drawback for users relying on digital audio passthrough
Only two M.2 sockets available, which may feel restrictive for storage-heavy builds
No clear CMOS button on the board, making BIOS resets less straightforward

Who is this for?

This board is a solid fit for users building a compact AMD AM5 system who want modern wireless connectivity without sacrificing expandability within a Micro-ATX footprint. The Wi-Fi 6E support and Bluetooth 5.3 make it well-suited for desktop setups where running ethernet is impractical. Users who plan to run multi-drive storage arrays will appreciate the native support for RAID 0, 1, 5, and 10, and the DDR5 platform with overclocking headroom up to 8200 MHz caters well to those who want to push memory performance on a mainstream board. The six fan headers and dual BIOS also make it a reasonable choice for builders who value thermal control and firmware reliability.

Who is this NOT for?

Users who need high-speed USB connectivity — such as content creators regularly transferring large files via USB 3.2 Gen 2x2 or USB 4 — will find the rear I/O limiting, as neither standard is present on this board. It is also a poor fit for workstation-oriented builds that depend on ECC memory for data integrity, since that capability is absent. Additionally, enthusiasts looking to take advantage of the latest PCIe 5.0 graphics cards or NVMe drives at full bandwidth will be constrained, as the board tops out at a single PCIe 4.0 x16 slot with no PCIe 5.0 option available.
