AM5 Socket Motherboard & CPU Combo

This bundle pairs an ASUS TUF Gaming B650M-PLUS board with an AMD Ryzen 9 9900X3D processor. The micro-ATX board uses the AM5 socket built for Ryzen 7000 series chips. It suits builders who want a matched platform for gaming and productivity without selecting parts separately.

12+2 Teamed Power Stages

The board delivers 12+2 teamed power stages backed by 8+4 ProCool sockets, alloy coils and durable capacitors. This design feeds the 120 W CPU cleanly during heavy workloads. DDR5 memory and a PCIe 5.0 M.2 slot provide fast data paths for modern GPUs and storage.

Sustained 120 W Operation

The processor runs at a 120 W base power with 128 MB L3 cache and 12 MB L2 cache. The power-stage array and ProCool connectors keep voltage steady during long render or compile sessions. Integrated Radeon graphics handle display output when a discrete card is not installed.

Questions about this item

How does the 128MB L3 cache on the Ryzen 9 9900X3D affect real-world gaming performance?

The large 128MB L3 cache keeps more game data close to the 12 CPU cores, reducing latency and delivering smoother frame rates in cache-sensitive titles without needing faster system memory.

What bandwidth ceiling does the PCIe 5.0 M.2 slot impose on a high-end SSD?

The PCIe 5.0 M.2 interface supports up to 5.0 GT/s per lane, letting a compatible drive reach its maximum sequential read and write speeds without being bottlenecked by the motherboard.

Will the Micro-ATX board and 12+2 power stages fit in a compact case with standard mounting holes?

The Micro-ATX form factor uses standard mounting points, and the 12+2 teamed power stages are built into the board, so it fits any case that accepts Micro-ATX motherboards.
