AM5 Motherboard and Ryzen 9 9900X Combo

This bundle pairs an ASUS TUF GAMING B850-E WIFI motherboard with an AMD Ryzen 9 9900X processor. The board uses the AMD AM5 socket and supports Ryzen 9000, 8000 and 7000 series CPUs. It is built for users who want a high-core-count system with DDR5 memory and modern connectivity.

Suits AI workloads and high-speed storage builds

The combination targets enthusiasts assembling an advanced AI PC or a workstation that needs three M.2 slots, Wi-Fi 6E and 2.5Gb Ethernet. The 12-core, 24-thread CPU reaches 5.6 GHz max boost and is unlocked for overclocking. Builders who require a different socket, fewer cores or a smaller board layout should consider other options.

8+2+1 80A DrMOS power stages and 8-layer PCB

This power design feeds the 9900X through 8+4 pin ProCool connectors with alloy chokes and durable capacitors. Stable delivery at high current is the specification that determines whether the board can sustain the CPU's boost behaviour under heavy multi-threaded loads.

Questions about this item

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

The combo supplies the motherboard and the Ryzen 9 9900X processor only; a compatible AM5 cooler is not included and must be purchased separately.

Which M.2 slot should I use for the fastest SSD?

Use the single PCIe 5.0 M.2 slot for the highest throughput; the other two slots run at PCIe 4.0 speeds.

What does the 5.6 GHz max boost mean for daily workloads?

The 12-core, 24-thread CPU can reach 5.6 GHz on lightly threaded tasks, while sustained all-core speeds will be lower depending on cooling and power limits.
