Product information

Description

The ASUS PRIME B840-PLUS WIFI is an ATX motherboard with AMD B840 chipset and Socket AM5, designed for AMD Ryzen 7000, 8000 and 9000 series processors. It supports DDR5 memory up to 192 GB across four DIMM slots, multiple PCI Express slots and a range of storage interfaces including M.2 and SATA III with RAID 0/1/5/10 support. Built-in 2.5 Gigabit Ethernet and Wi‑Fi 6E (802.11ax) provide high-speed wired and wireless connectivity, and the board includes features and firmware intended to support advanced AI PC workloads.

Advantages

The PRIME B840-PLUS WIFI combines an AM5 socket and B840 chipset to support the latest Ryzen processors while offering DDR5 memory support for improved bandwidth. Integrated networking options—2.5 Gb Ethernet and Wi‑Fi 6E—enable fast local and wireless connections. Multiple M.2 and SATA III ports allow flexible storage configurations with hardware RAID options. The ATX form factor and a variety of PCIe slots provide expansion capability for graphics, NVMe storage and add-in cards.

Suitable for

  • Building a desktop PC with AMD Ryzen 7000/8000/9000 series CPUs
  • Systems requiring fast wired and wireless networking (2.5 GbE and Wi‑Fi 6E)
  • Workstations or home PCs that need multiple NVMe and SATA drives or RAID
  • Users who plan to add discrete GPUs and expansion cards in an ATX chassis

Key specifications

  • Form factor: ATX
  • Chipset: AMD B840
  • CPU socket: Socket AM5 (supports Ryzen 7000/8000/9000 series)
  • Memory: DDR5, 4 DIMM slots, up to 192 GB
  • PCIe slots: 3 x PCIe x16 (Gen 3.x), 1 x PCIe x1 (Gen 3.x)
  • Storage: M.2 and SATA III interfaces; RAID levels 0, 1, 5, 10 supported
  • Networking: 2.5 Gigabit Ethernet, Wi‑Fi 6E (802.11ax)

How to use

Install a compatible AM5 CPU and DDR5 modules into the appropriate socket and DIMM slots, secure the motherboard in an ATX case, and connect power supply cables to the 24‑pin and CPU headers. Populate M.2 or SATA drives as needed and configure RAID in the firmware if required. Connect peripherals to available PCIe slots and use the rear I/O for network and USB connections. Update the BIOS/UEFI and drivers from the ASUS support site to ensure full compatibility with Ryzen processors and Wi‑Fi 6E functionality.

Usage recommendations

For stable performance with high-speed memory and networking features, use high-quality DDR5 modules rated for your intended workloads, a compatible power supply with adequate CPU power connectors, and the latest BIOS version provided by ASUS.
