ASUS PRIME B650M-R and Ryzen 9 9900X3D combo

This bundle pairs an ASUS PRIME B650M-R motherboard with an AMD Ryzen 9 9900X3D processor. The AM5 socket board uses the B650 chipset in a Micro-ATX layout. The 12-core CPU runs at a 120W TDP and includes 128MB L3 cache plus integrated Radeon graphics. It targets builders who want a ready-to-go platform for AI workloads and high-end gaming.

Micro-ATX board with VRM and PCH heatsinks

The motherboard features a VRM heatsink and a PCH heatsink to manage thermals during sustained loads. Hybrid fan headers connect to Fan Xpert 2+ software for automated curve control. Connectivity includes PCIe 4.0, two M.2 slots, SATA 6 Gbps ports, Realtek 2.5Gb Ethernet, USB 5Gbps Type-A and a front-panel USB 5Gbps Type-C connector. Addressable Gen 2 RGB headers support Aura Sync lighting strips.

AI noise cancelation and Fan Xpert 2+ software

Two-way AI Noise Cancelation reduces background sound on both microphone input and audio output for clearer calls and streams. Fan Xpert 2+ provides a graphical interface to tune every connected fan based on temperature sensors. Aura Sync software coordinates RGB effects across compatible components. The integrated Radeon graphics enable display output without a discrete card for troubleshooting or light use.
