Combo for high-end builds

This bundle pairs the ASUS B850M AYW GAMING WIFI motherboard with the AMD Ryzen 9 9950X processor. The 16-core, 32-thread CPU reaches a 5.7 GHz max boost and is unlocked for overclocking. It targets enthusiasts building workstations or high-refresh gaming rigs on the AM5 platform.

DDR5 capacity and storage headroom

Dual-channel DDR5 supports up to 128 GB at 4733+ MHz OC, while the CPU natively handles DDR5-5600. Storage includes one PCIe 4.0 M.2 slot, one PCIe 3.0 M.2 slot and six SATA 6Gb/s ports. The single 4.0 lane may limit simultaneous peak throughput for multiple high-speed drives.

Connectivity and expansion layout

Rear I/O provides a USB 3.2 Gen2 Type-C port, eight USB 3.2 Gen1 Type-A ports and HDMI 2.0b video output. Networking uses Wi-Fi 6, 2.5Gb Ethernet and Bluetooth 5.2. Audio runs through a Realtek ALC1220 codec with an ESS SABRE ES9218C DAC. Expansion centres on a PCIe 4.0 x16 slot plus reinforced PCIe 3.0 slots.

Questions about this item

Will my existing DDR5 modules run at their rated speed with the Ryzen 9 9950X on this B850M AYW GAMING WIFI board?

The board supports dual-channel DDR5 up to 128GB at 4733+ MHz OC, while the CPU officially supports DDR5-5600; actual speed depends on the memory kit and BIOS settings.

How can I confirm the Wi-Fi 6 and 2.5Gb Ethernet are active after building the system?

Check Device Manager for the Wi-Fi 6 (802.11ax) and Realtek 2.5Gb Ethernet adapters, then run a speed test or file transfer to verify throughput on each interface.

Does the combo include a CPU cooler or must I buy one separately?

The Ryzen 9 9950X ships without a cooler, so you must purchase a compatible AM5 cooler; the motherboard box contains the board, I/O shield, cables, antennas and documentation.
