Engineered for Ryzen 7000 Performance
Built on the AMD B650 chipset, this board supports AMD Ryzen 7000 and 8000-series processors, unlocking high core-count performance and PCIe 5.0 lanes for future GPUs. The Digi+ VRM delivers precise power delivery to keep demanding workloads stable, while the 2oz copper PCB aids heat dissipation under load.
Cooling That Keeps Up
The PRIME B650M-R features a VRM heatsink and thermal pads to improve heat transfer from MOSFETs and chokes. ASUS Fan Xpert 2+ software allows granular fan control, including an Auto-Tuning mode and Extreme Quiet profile for silent light tasks. A back-to-BIOS button also simplifies recovery if a BIOS flash goes wrong.
Storage Flexibility
With two PCIe 4.0 M.2 slots, you can run ultra-fast NVMe SSDs for boot and application drives. Four SATA III ports support additional HDDs or SSDs, and RAID 0/1/10 configurations are available for performance or redundancy. Storage expansion is straightforward for both gamers and content creators.
Connectivity & Expansion
The board offers two PCIe 4.0 x16 slots for dual-GPU setups, one PCIe 4.0 x1 slot, and a front USB 3.2 Gen 1 Type-C header for modern peripherals. Realtek 2.5 Gb Ethernet reduces CPU overhead for smoother online gaming and file transfers. Audio is handled by a 7.1-channel HD system with shielding and premium capacitors for clear sound.
Aura Sync RGB
ASUS Aura Sync lets you customise onboard RGB LEDs or sync addressable RGB strips via two Gen 2 headers. You can also disable all lighting for a stealth build. Armoury Crate software centralises lighting, fan, and device control in one interface.
