Your Next Build Starts Here

The ASUS PRIME B840M-A WIFI is the ultimate foundation for builders who refuse to compromise. Whether you’re assembling a high-performance gaming rig, a creative workstation, or an AI-ready desktop, this compact M-ATX board delivers full-size ambition in a smaller footprint — supporting the latest AMD Ryzen 9000, 8000, and 7000 Series processors right out of the box.

Blazing Speed, No Bottlenecks

With DDR5 memory support up to 7600+ MT/s and three M.2 slots (two PCIe 4.0, one PCIe 3.0), your system loads faster, renders quicker, and transfers data without breaking a sweat. ASUS AEMP and AMD EXPO profiles make overclocking accessible for every skill level, letting you squeeze every drop of performance out of your build.

Connected to Everything, Held Back by Nothing

Integrated Wi-Fi 6E, Realtek 2.5Gb Ethernet, USB 10Gbps Type-A, and USB 5Gbps Type-C ports keep you wired, wireless, and ready for whatever the internet throws at you. Whether you’re gaming online, streaming in 4K, or transferring massive project files, lag and bottlenecks simply aren’t part of the equation.

Light It Up, Keep It Cool

Aura Sync-compatible RGB headers let you personalise your build’s aesthetic with full lighting control across Gen 2 addressable devices. Meanwhile, the VRM heatsink, passive chipset heatsink, hybrid fan headers, and AiO pump support work together to keep thermals in check — so your system looks great and performs even better under pressure.
