Combo for AMD Ryzen 9000 series

This bundle pairs an ASUS TUF GAMING B650EM-PLUS WIFI motherboard with an AMD Ryzen 9 9900X3D processor. The board uses the AM5 socket and supports Ryzen 9000, 8000 and 7000 series CPUs. It targets builders who want a ready-matched platform for high-core-count workloads and gaming.

Enhanced power and AI noise cancellation

The motherboard delivers 12+2 teamed power stages with 8+4 ProCool sockets, alloy chokes and durable capacitors for stable delivery to the 120W CPU. Two-way AI Noise Cancelation reduces background sound from both microphone input and audio output, improving clarity in games and video calls.

PCIe 5.0 M.2 and USB4 limits

The single M.2 slot wired for PCIe 5.0 x4 will run at PCIe 4.0 speeds when a PCIe 4.0 drive is installed, and bandwidth is shared with other controllers so maximum throughput may not be sustained. USB4 support relies on the CPU's USB4 implementation and requires compatible cables and devices to reach full capability.
