Efficient power delivery and energy saving
The PRIME B840-PLUS WIFI offers an 8+2+1 power stage design with MOSFET transistors that ensure stable and efficient power delivery to AMD processors, contributing to overall stability and performance in daily use. The multi-layered board design quickly dissipates heat from the voltage regulators, which improves system stability and enables better processor overclocking. The Power Saving function provides several options for optimising energy consumption, such as limiting CPU power, dimming Aura lighting, and setting a fan power-saving mode. With support for Windows' integrated power-saving plan and a Digi+ VRM module for real-time voltage control, the board offers high energy efficiency.
Higher DDR5 performance and fast storage
The PRIME B840-PLUS WIFI offers comprehensive memory tuning features that maximise the potential of DDR5 modules, from entry-level to extremely fast kits. With the ASUS Enhanced Memory Profile (AEMP) for basic modules without EXPO™ support, it automatically detects memory chips and optimises performance. For enthusiasts who want to surpass standard DDR5 speeds, the board offers support for extended AMD EXPO™ profiles and extensive UEFI settings for further overclocking. It also adds three M.2 slots, two of which support transfer speeds of up to 64Gb/s via PCIe 4.0, ensuring faster system boot and application load times.
Cooler performance with advanced cooling on the PRIME B840-PLUS WIFI
The PRIME B840-PLUS WIFI motherboard is designed for effective cooling even under high loads. It features several integrated heatsinks, including a VRM heatsink, a passive chipset heatsink, an M.2 heatsink, and thermal pads. It also offers a hybrid fan header, a 4-pin PWM/DC fan header, an AIO pump header, and multiple temperature sensors for comprehensive cooling control. ASUS Fan Xpert 2+ software provides intelligent control over the fans, including auto-tuning and an extremely quiet mode to minimise noise during light tasks. The fans can be easily controlled via the UEFI BIOS. ASUS AIO coolers offer high performance and customisable features for optimal overclocking and long-term system stability.
Upgraded connectors for fast connectivity
The PRIME B840-PLUS WIFI motherboard offers excellent connectivity options, including support for WiFi 6E, a PCIe 4.0 slot, and USB ports, including a fast USB Type-C®. WiFi 6E technology uses the 6GHz band, which ensures ultra-fast wireless connectivity with better performance and capacity in demanding wireless environments. The integrated Realtek 2.5Gb Ethernet provides high throughput, reduces CPU load, and ensures faster, smoother data transfers. The USB ports include a rear USB Type-C® connector with a transfer speed of up to 10Gb/s, ideal for connecting numerous high-throughput peripherals.
Enhanced user experience with advanced control and customisation
The PRIME B840-PLUS WIFI delivers simplified configuration options with the BIOS Q-Dashboard tool, which lets you easily visualise hardware connections and their corresponding BIOS settings, simplifying the entire setup process. ASUS GlideX boosts productivity and enables easy screen sharing and control across devices like PCs, tablets, and smartphones, via both wired and wireless connections. ASUS DriverHub then simplifies driver and utility management for optimal system performance, automatically detecting updates and allowing you to install them with a single click. With Armoury Crate, you can easily customise RGB lighting with Aura Sync technology and synchronise lighting effects across your entire arsenal of compatible devices.
Advanced control and customisation with UEFI BIOS and ASUS MyHotkey
The PRIME B840-PLUS WIFI motherboard offers an intuitive Advanced Mode in the UEFI BIOS, giving you full control over performance settings and allowing you to fine-tune them to your needs. A search function makes it easy to quickly find the settings you want. ASUS MyHotkey offers flexibility in customising keys to control the BIOS, enabling you to efficiently switch between different functions like ASUS EZ Flash 3 or booting from a specific device during POST. The EZ Mode in the BIOS simplifies setup by displaying important options and statistics and offers drag-and-drop functions for quick application. Intuitive graphical fan control and the ability to easily turn Aura RGB lighting on/off provide simple management and adjustment of your build's aesthetic and performance parameters.
Suitable for DIY builds
The PRIME B840-PLUS WIFI motherboard is ideal for enthusiasts who enjoy building their own PCs. Equipped with EZ PC DIY innovations, it makes the entire assembly process easier and faster. The Q-Antenna offers quick and easy Wi-Fi antenna connection without the need for complex fastener rotation, ensuring stable performance. The pre-mounted I/O shield protects the ports, simplifies installation, and enhances the build's appearance. The BIOS FlashBack™ feature lets you easily update the BIOS without needing a CPU or memory. SafeSlot Core+ provides strong protection for PCIe slots, ensuring secure support for heavy graphics cards. Q-LED Core simplifies diagnostics with colour-coded lights during the POST test. With these innovations, building a PC is not only easy, but also efficient.
