AI Advisor

ASUS AI Advisor allows users to explore the functionality and advanced features of ASUS motherboards in a simple and straightforward way.

Digital Power Design

The PRIME B840-PLUS WIFI features an 8+2+1 phase power design with discrete MOSFETs, ensuring efficient and stable power delivery for AMD processors and consistent performance for everyday use.

Enhanced DDR5 Performance

The comprehensive memory tuning options are the cornerstone of PRIME motherboards. The PRIME B840M-A maximizes the capabilities of DDR5 modules, from entry-level to extreme speed kits.
For entry-level modules without EXPO™ support, the ASUS Enhanced Memory Profile (AEMP) automatically detects memory chips and provides optimized profiles for improved performance. For those looking to surpass standard DDR5 speeds, the PRIME B840M-A offers extensive support for AMD Extended Profiles for Overclocking (EXPO™) and a wide range of UEFI settings for further performance enhancements.

Three M.2 slots (up to 64 Gbps)

The PRIME B840-PLUS WIFI offers a total of three M.2 slots, two of which support data transfer speeds of up to 64 Gbps via PCIe 4.0 and one supports PCIe 3.0. This allows for faster boot and application load times with operating system or application drives.

ASUS Fan Xpert 2+

The ASUS Fan Xpert 2+ software provides comprehensive control of the fans. An auto-tuning function intelligently adjusts all parameters with a single click. There is also an Extreme Quiet mode that reduces the chassis fan speeds below the default minimum limit, so your system remains quiet during light tasks. The fans can also be controlled via the UEFI BIOS.

Cooler Compatibility

ASUS AIO coolers offer powerful performance, high overclocking capabilities, bold aesthetics, and customizable features for new motherboards, giving you the ability to create the gaming machine of your dreams.

WiFi 6E

The integrated WiFi 6E technology takes advantage of the newly available radio spectrum in the 6 GHz band. With triple the bandwidth compared to the 2.4/5/6 GHz band, WiFi 6E provides ultra-fast wireless networking speeds with improved capacity and better performance in dense wireless environments.

Realtek 2.5 Gb Ethernet

The Realtek 2.5 Gb Ethernet reduces CPU load and offers ultra-high TCP and UDP performance for faster and smoother data transfers.

USB 10Gbps Type-C®

A series of USB ports support high-spec equipment loaded with peripherals, including a rear USB Type-C® socket with USB 10Gbps super speed for transfer speeds of up to 10Gbps.

BIOS FlashBack™

BIOS FlashBack™ simplifies BIOS updates. Simply load the BIOS file onto a FAT32 USB stick, insert it into the BIOS FlashBack™ port, and press a button - no CPU or memory required.

Bios Flashback

Ability to update the BIOS without requiring a CPU and RAM installed on the motherboard. This advanced feature is intended for experienced users and is useful for supporting newer processors on older motherboards. Please refer to the manufacturer's instructions for the process, as it may vary between manufacturers.

For example, if you want to install a Ryzen 5000 series processor on a chipset that only supports it after a BIOS upgrade, BIOS Flashback can be used without having an older processor on the motherboard.
