The ASUS TUF GAMING B860-PLUS WIFI is an ATX motherboard built around the Intel B860 chipset and LGA1851 processor socket, providing a platform for Intel Core Ultra processors (Series 2). Designed for gaming systems, creator PCs and custom desktop builds, it combines DDR5 memory support, PCIe expansion, SATA and M.2 storage connectivity, integrated networking, extensive USB connectivity and 8-channel HD Audio. Onboard graphics functionality is available when a compatible CPU with the required graphics capability is installed, with both HDMI and DisplayPort connections provided for display output
Memory support is provided through four 288-pin DIMM slots using DDR5 SDRAM. The board supports a maximum memory capacity of 256 GB and memory bus speeds of up to 4333 MHz when overclocked. Its memory architecture operates in dual-channel mode and supports Intel Extreme Memory Profiles (XMP) as well as ASUS Enhanced Memory Profile (AEMP) III. Supported memory is unbuffered and includes non-ECC and on-die ECC support, giving builders a comprehensive DDR5 platform for configuring system memory.
Expansion and storage options cover both current high-bandwidth components and conventional SATA devices. The motherboard provides a PCIe 5.0 x16 slot, a PCIe 4.0 x16 slot operating in x4 mode and a PCIe 4.0 x1 slot. Three M.2 sockets are available in total, comprising one socket compatible with 2242, 2260 and 2280 M.2 Key M devices, one 2280 M.2 slot and another M.2 Key M socket supporting 2280 and 22110 formats. Storage connectivity consists of one PCIe 5.0 M.2 connection, two PCIe 4.0 M.2 connections and four SATA-600 connectors. SATA RAID functionality includes RAID 0, RAID 1, RAID 5 and RAID 10.
Thermal management is incorporated into the motherboard through dedicated M.2 heatsinks and a VRM heatsink design. These components are intended to dissipate heat from key areas of the board during demanding gaming and workload conditions. Power delivery is based on a 12+1+2+1 phase design with 80A power stages and Dr.MOS MOSFET technology, complemented by ASUS DIGI+ VRM and ASUS ProCool. The motherboard uses a six-layer PCB as part of its overall construction.
For wired networking, the TUF GAMING B860-PLUS WIFI includes 2.5 Gigabit Ethernet. Wireless networking encompasses the 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax and 802.11be standards, with 802.11be providing Wi-Fi 7 connectivity. Bluetooth 5.4 is also integrated for compatible wireless peripherals and devices. An ASUS Wi-Fi Q-antenna is supplied with the motherboard, and the rear connectivity includes two aerial connections for the wireless hardware.
The external connection selection accommodates displays, storage devices, peripherals, networking equipment and audio hardware. It includes HDMI and DisplayPort, three USB 3.2 Gen 1 ports, two USB 3.2 Gen 2 ports, two USB 2.0 ports and one USB-C 3.2 Gen 2x2 connection that also supports DisplayPort. The board additionally provides a 2.5 Gigabit Ethernet LAN port and a comprehensive set of audio connections consisting of microphone input, line input, line output, centre/subwoofer output, rear-channel output and SPDIF output.
Additional connections can be made through the motherboard's internal headers. These comprise one USB-C 3.2 Gen 2 header, two USB 3.2 Gen 1 headers, two USB 2.0 headers, one serial header, one audio header and one Thunderbolt 4 header. Taken together with the rear I/O, the specified USB provision consists of one USB-C 3.2 Gen 2x2 port, two USB 3.2 Gen 2 ports, three USB 3.2 Gen 1 ports and two USB 2.0 ports externally, plus one USB-C 3.2 Gen 2 connection, two USB 3.2 Gen 1 connections and two USB 2.0 connections available through headers.
Audio is handled by an 8-channel HD Audio implementation compliant with the High Definition Audio standard. This is supported by the motherboard's multiple analogue audio connections and SPDIF output, providing integrated audio functionality without requiring a separate sound card for the specified audio capabilities.
ASUS incorporates a broad collection of TUF protection, power and installation technologies into the board. ASUS TUF Protection is joined by overvoltage protection, TUF LANGuard, ASUS SafeSlot Core, SafeDIMM and an ASUS stainless-steel rear I/O. Installation and component-management features include ASUS Q-Design, M.2 Q-Latch, PCIe Slot Q-Release, Q-Antenna, Q-Dashboard, Q-DIMM, Q-LED Core, Q-Slot and ASUS EZ DIY. These features are accompanied by the motherboard's M.2 and VRM heatsinks, ASUS DIGI+ VRM and ASUS ProCool hardware.
The firmware platform uses an AMI BIOS with UEFI BIOS functionality, ASUS EZ Flash and ASUS UEFI BIOS EZ Mode. Wake on LAN and wake on PME functionality are supported, while Preboot eXecution Environment (PXE) is also included among the motherboard's hardware capabilities.
Power is supplied to the motherboard through a 24-pin main power connector together with two 8-pin ATX12V connectors. The ATX board measures 30.5 cm wide and 24.4 cm deep and is supplied in a box package. Included physical accessories consist of the ASUS Wi-Fi Q-antenna, two M.2 rubber packages, an M.2 screw package, a TUF GAMING sticker and two Serial ATA cables.
The supplied software collection includes Armoury Crate, ASUS Fan Xpert 4, ASUS DriverHub, ASUS GlideX, ASUS TUF GAMING CPU-Z and DTS Audio Processing. It also includes a free trial of Adobe Creative Cloud, a 60-day trial of Norton 360 for Gamers and a 40-day trial of WinRAR, providing the specified ASUS utilities and trial software alongside the motherboard.
