The Gigabyte B860M Aorus Elite is built on the LGA 1851 socket and pairs with the B860 chipset, fitting into a Micro-ATX form factor at 244 mm × 244 mm. It supports a single CPU and does not include an integrated CPU or integrated graphics. The board features dual BIOS for firmware redundancy and allows easy overclocking, though resetting the BIOS via a dedicated clear CMOS button is not supported. RGB lighting is present, and video output is handled through an HDMI 2.1 connector. Wi-Fi and Bluetooth are not built in, and the board carries a three-year warranty.
The board supports DDR5 memory across four slots in a dual-channel configuration, with a maximum capacity of 256 GB. Standard RAM speeds top out at 6400 MHz, while overclocked profiles can reach up to 9200 MHz. ECC memory is not supported.
The rear I/O offers a solid spread of USB connectivity, including two USB 3.2 Gen 2 Type-A ports, four USB 3.2 Gen 1 Type-A ports, and four USB 2.0 ports, alongside a Thunderbolt 4 port that also serves as the single USB 4 40Gbps connection. There are no USB 3.2 Gen 2 Type-C, Gen 1 Type-C, Gen 2x2, or USB 4 20Gbps ports, and no Thunderbolt 3. Display output is covered by an HDMI connector and one DisplayPort, with no DVI or VGA options present. Networking is handled by a single RJ45 port, and there are no eSATA or PS/2 ports.
For internal expansion, the board provides two USB 3.2 Gen 1 headers, two USB 3.0 headers, one USB-C 3.2 Gen 2 header, and four USB 2.0 headers, covering a wide range of front-panel connectivity needs. Storage is well served by three M.2 sockets and four SATA 3 connectors, while SATA 2, U.2, and mSATA are not available. Cooling is managed through six fan headers, and a TPM connector is present for security module support.
The board offers two expansion slots in total: one PCIe 5.0 x16 slot for the primary card and one PCIe x4 slot for additional expansion. There are no PCIe 4.0 x16, PCIe 3.0 x16, PCIe 2.0 x16, PCIe x8, PCIe x1, or legacy PCI slots available.
The board delivers 7.1-channel audio output through two audio connectors on the rear I/O, and includes an S/PDIF Out port for digital audio passthrough to compatible receivers or DACs.
The board supports RAID 0, 1, 5, and 10 configurations, covering a range of performance and redundancy setups. RAID 0+1 is not supported.
