Gigabyte B860M Eagle WiFi6

Name: Gigabyte B860M Eagle WiFi6
Brand: Gigabyte
SKU: 17593

Manufacturer: Gigabyte

The Gigabyte B860M Eagle WiFi6 is a Micro-ATX motherboard built around Intel's LGA 1851 socket and the B860 chipset, offering a compact 244 × 225 mm footprint that suits space-conscious builds. It ships with integrated Wi-Fi 6 (802.11ax) and Bluetooth 5.3, covering wireless connectivity without requiring add-in cards. A dual BIOS design is included, and the board carries a three-year warranty.

Memory support extends to DDR5 across two slots, with a rated maximum of 6400 MHz and overclocked profiles reaching up to 9066 MHz, for a total capacity of 128 GB across dual channels. Storage options include two M.2 sockets, four SATA 3 connectors, and full RAID 0, 1, 5, and 10 support. Rear connectivity provides three USB 3.2 Gen 1 Type-A ports, three USB 2.0 ports, HDMI 2.1, one DisplayPort output, and a single RJ45 port. The expansion layout features one PCIe 5.0 x16 slot and one PCIe x4 slot, while onboard audio handles 7.1-channel output through three audio connectors.

Pros

Dual BIOS provides a fallback option if the primary BIOS becomes corrupted
Wi-Fi 6 support is built in, eliminating the need for a separate wireless adapter
DDR5 memory with overclocked speeds up to 9066 MHz offers substantial headroom for memory-sensitive workloads
PCIe 5.0 x16 slot accommodates the latest generation of expansion cards
RAID 0, 1, 5, and 10 support gives meaningful flexibility for multi-drive storage configurations
Three-year warranty period offers solid long-term coverage

Cons

Only two memory slots limits upgrade flexibility and restricts multi-stick configurations
No USB Type-C ports are available on the rear I/O panel
No USB 3.2 Gen 2 ports are present, capping rear USB throughput at Gen 1 speeds
ECC memory is not supported, ruling out error-correcting memory use cases
No S/PDIF Out port means digital audio passthrough to external receivers is not available
No clear CMOS button makes BIOS resets less straightforward

Who is this for?

This board is a practical choice for users building a compact desktop around Intel's LGA 1851 platform who want integrated Wi-Fi 6 and Bluetooth 5.3 without relying on add-in cards. The PCIe 5.0 x16 slot and DDR5 memory support with overclocked speeds up to 9066 MHz make it well-suited for those who want a capable, forward-looking system in a Micro-ATX footprint. Users who need flexible multi-drive storage configurations, including RAID 0, 1, 5, and 10 across four SATA 3 ports and two M.2 sockets, will find the storage options adequate for both performance and redundancy needs.

Who is this NOT for?

This board is a poor fit for users who require high-speed USB connectivity on the rear panel, as it lacks USB Type-C, USB 3.2 Gen 2, USB 4, and Thunderbolt ports entirely. Those working in environments where ECC memory is essential — such as workstation or server-adjacent tasks — will need to look elsewhere, as error-correcting memory is not supported. The two-slot memory configuration also makes this a less ideal platform for users who anticipate needing more than two physical DIMMs or want greater channel expansion flexibility.

Final Verdict

The Gigabyte B860M Eagle WiFi6 is a focused Micro-ATX offering for the LGA 1851 platform that keeps its priorities clear: built-in Wi-Fi 6, dual BIOS reliability, and a PCIe 5.0 x16 slot paired with DDR5 memory support give it a genuinely current foundation within a compact form factor. Its storage versatility, spanning two M.2 sockets, four SATA 3 connectors, and broad RAID support, adds practical value for users who need more than a basic drive setup. The rear I/O does show its limits, particularly the absence of USB Type-C and high-speed USB options, and the two-slot memory layout leaves little room for expansion. For builders who want a capable, no-frills Micro-ATX board on the Intel B860 platform with wireless built in and room for current-generation hardware, this board delivers where it counts.
