ASUS PRIME B860M-A WIFI-CSM LGA 1851 M-ATX Motherboard

The ASUS PRIME B860M-A WIFI-CSM is a motherboard in the micro ATX form factor that lets you tap into the power of Intel Core Ultra series 2 processors through the LGA 1851 socket. It fits easily into compact cases yet delivers the bandwidth, storage options, and connectivity you would normally expect from a full-sized board.

Two M.2 slots make it simple to pair a PCIe 5.0 SSD for an operating system or application drive with a PCIe 4.0 SSD for bulk files. Four additional SATA ports give you room for larger hard drives or legacy SSDs, so creators can keep project assets close at hand and gamers can maintain an extensive game library. You can install up to 192 GB of DDR5 memory, and the board’s design supports speeds up to 8400 MT/s, which helps with tasks such as high-resolution video editing, 3D rendering, or multi-tab browsing while streaming.

For graphics, a PCIe 5.0 x16 slot stands ready for a modern GPU. If you prefer to run on integrated graphics, HDMI and DisplayPort outputs handle monitors up to 4K at 60 Hz, making this board a practical base for an office workstation or media center.

Networking and wireless features keep pace with demanding workloads. Built-in Wi-Fi 6E paired with Bluetooth 5.3 offers quick setup for cable-free desktops, while 2.5 Gigabit Ethernet delivers low-latency, high-throughput performance for competitive gaming or large cloud backups. A rear USB-C port pushes 20 Gbps for fast external storage transfers or docking stations.

Audio comes from a Realtek solution that supports 7.1-channel surround sound, so you can enjoy clear voice calls, detailed in-game audio cues, or immersive media playback. The board also includes multiple fan headers, built-in temperature sensors, and ASUS Q-Design touches like a pre-installed I/O shield, tool-less M.2 latches, and quick-release PCIe clips, all of which streamline the building and maintenance process.

Whether you are assembling a space-saving gaming rig, a content creation workstation in a small studio, or a home server that doubles as an AI development box, the PRIME B860M-A WIFI-CSM brings balanced performance, reliable connectivity, and builder-friendly features to a compact PC.
