ASROCK B650 Pro RS DDR5 AMD Motherboard

The ASRock B650 Pro RS is an ATX-form-factor motherboard built on the AMD B650 chipset, designed to pair with AMD Socket AM5 Ryzen 7000 Series processors. It combines a robust 14+2+1 phase power design using 60A Smart Power Stage (SPS) MOSFETs with an enlarged heatsink to keep the voltage regulator running efficiently under sustained workloads. Memory flexibility is a highlight: four DDR5 DIMM slots support dual-channel non-ECC, unbuffered memory up to 128 GB total, with speeds reaching DDR5-6200+ in overclocked mode. Both AMD EXPO and Intel XMP memory profiles are supported, allowing straightforward performance tuning through the BIOS. Storage options cover the full range of current interfaces. The primary M.2 socket (M2_1) connects directly to the CPU via PCIe Gen5 x4, delivering up to 128 Gb/s throughput. A second M.2 socket (M2_3) supports PCIe Gen4 x4 at up to 64 Gb/s, while a third (M2_2) handles PCIe Gen3 x2 and SATA3. Four SATA3 6.0 Gb/s ports—two native and two via an ASMedia ASM1061 controller—round out storage connectivity. RAID 0 and RAID 1 are supported for SATA devices; RAID 0, 1, and 10 are available for NVMe devices. Expansion slots include one PCIe 4.0 x16 slot wired directly to the CPU for the primary graphics card, one PCIe 3.0 x16 slot (running at x4) from the chipset, one PCIe 4.0 x1 slot, and an M.2 Key-E socket for a 2230-type Wi-Fi module. Connectivity is handled by a Realtek Dragon RTL8125BG 2.5 Gigabit LAN controller supporting 10/100/1000/2500 Mb/s. USB ports include a front-panel USB 3.2 Gen2x2 Type-C header (20 Gb/s), rear USB 3.2 Gen2 Type-C (10 Gb/s) and Type-A (10 Gb/s), plus 4× USB 3.2 Gen1 and 9× USB 2.0 ports distributed across front headers and rear I/O. Audio is handled by a Realtek ALC897 codec delivering 7.1-channel HD audio with Nahimic Audio software support. Display output options include one HDMI 2.1 port (up to 4K 120Hz, HDR, HDCP 2.3) and one DisplayPort 1.4 with DSC (up to 4K 120Hz, HDCP 2.3), contingent on a CPU with integrated AMD RDNA 2 graphics. RGB lighting headers consist of one 12V RGB header and three 5V addressable LED headers, managed via ASRock Polychrome SYNC software.
