Description
Introducing the Asus PRIME B840-PLUS WIFI AMD AM5 ATX Gaming Motherboard. A feature-rich and future-focused platform engineered to unlock the full capabilities of AMDs latest Ryzen desktop processors. Built on the AMD B840 chipset, this motherboard supports AMD Ryzen 7000, 8000, and 9000 Series processors, providing a powerful foundation for gaming, content creation, productivity, and emerging AI-driven workloads. Designed with both performance enthusiasts and PC builders in mind, the PRIME B840-PLUS WIFI combines advanced connectivity, intelligent tuning features, and reliable power delivery to create a versatile and dependable computing platform.
At the core of the motherboards performance is its support for DDR5 memory, allowing users to take advantage of next-generation memory speeds and bandwidth. Featuring four DIMM slots with support for up to 256GB of DDR5 memory, the board can accommodate memory frequencies of up to 7600+ MT/s (OC). ASUS further enhances memory optimization with ASUS Enhanced Memory Profile (AEMP), which automatically detects compatible memory modules and applies optimized settings to improve stability and performance, even on entry-level memory kits. Storage performance is another key strength of the PRIME B840-PLUS WIFI. The motherboard includes three M.2 slots, two of which support PCIe 4.0 x4 connectivity for ultra-fast NVMe solid-state drives capable of delivering data transfer speeds of up to 64Gbps. These high-speed storage options significantly reduce boot times, accelerate application loading, and improve overall system responsiveness. In addition, four SATA 6Gb/s ports provide flexible support for larger-capacity storage drives and RAID-enabled configurations.
For gaming and graphics-intensive applications, the motherboard features a dedicated PCIe 4.0 x16 slot, providing the bandwidth required by modern graphics cards. Additional PCIe expansion slots offer flexibility for installing capture cards, storage controllers, networking cards, and other expansion devices. This balanced configuration makes the motherboard well-suited for both high-performance gaming systems and productivity-focused workstations. Networking capabilities are designed to meet the demands of modern users. Integrated Wi-Fi 6E support delivers ultra-fast wireless connectivity with access to the expanded 6GHz spectrum, offering greater bandwidth, reduced latency, and improved performance in crowded wireless environments. Complementing the wireless capabilities is Realtek 2.5Gb Ethernet with ASUS LANGuard, providing a fast and reliable wired networking solution for online gaming, large file transfers, streaming, and professional workloads.
The PRIME B840-PLUS WIFI also offers extensive connectivity options for peripherals and accessories. Rear I/O includes USB 10Gbps Type-A and USB Type-C ports, multiple USB 5Gbps ports, and additional USB 2.0 connections for broad device compatibility. Front-panel USB headers further expand connectivity, including support for front-facing USB Type-C ports. These options ensure convenient access to high-speed data transfer and seamless integration with modern peripherals. To maintain stable operation during intensive workloads, ASUS has equipped the motherboard with a comprehensive thermal design. Multiple onboard heatsinks, hybrid fan headers, and intelligent cooling controls work together to manage temperatures effectively. An 8+2+1 phase power design with discrete MOSFETs delivers efficient and reliable power to the processor, helping maintain performance consistency during gaming, multitasking, and demanding computing tasks.
Audio quality is handled by the onboard Realtek 7.1 Surround Sound High Definition Audio CODEC, providing immersive sound for gaming, entertainment, and communication. Display connectivity is available through both HDMI and DisplayPort outputs, enabling flexible monitor configurations when using compatible Ryzen processors with integrated graphics capabilities. Aesthetics and customization are also an important part of the PRIME B840-PLUS WIFI experience. With support for Aura Sync RGB Lighting, users can synchronize compatible lighting devices and components to create a personalized system appearance. Combined with its full-size ATX form factor, advanced DDR5 support, PCIe 4.0 connectivity, Wi-Fi 6E networking, robust cooling design, and compatibility with the latest AMD Ryzen processors, the ASUS PRIME B840-PLUS WIFI AMD AM5 ATX Gaming Motherboard provides an outstanding platform for building a powerful, modern, and future-ready desktop PC.
