ASUS Prime B650-Plus-CSM AMD B650 Socket AM5 ATX Motherboard

ASUS Prime B650-Plus-CSM AMD B650 Socket AM5 ATX Motherboard arrives as a robust ATX platform for AMD Ryzen 7000 Series builders seeking balanced performance and enterprise-friendly manageability.

This Prime B650-Plus-CSM motherboard supports AMD processors in the Socket AM5 family and is built around the AMD B650 chipset, offering broad compatibility with Ryzen 7000 CPUs and a UEFI AMI BIOS with 256 Mbit memory for reliable system initialization and updates.

Memory support is generous and modern, with four DIMM slots for DDR5-SDRAM in a dual-channel configuration, supporting ECC and non-ECC modules up to a combined 128 GB and speeds from 4800 MHz up to 6400 MHz for responsive multitasking and content creation workflows.

Storage and expandability are well covered with two M.2 slots, four SATA III connectors, RAID support for levels 0, 1 and 10, plus two PCIe x16 (Gen4) and two PCIe x1 (Gen4) expansion slots to add GPUs, NVMe storage or I/O cards. One M.2 (E) slot is also included for wireless modules or other specialized cards.

Connectivity on the rear I/O includes USB 3.2 Gen 2 Type-A (3 ports), USB 3.2 Gen 2 Type-C (1 port), USB 3.2 Gen 1 and USB 2.0 ports, a single 2.5 Gigabit Ethernet RJ-45 port, HDMI 2.1 and DisplayPort 1.4 video outputs, and high-fidelity 7.1-channel audio with line-in, microphone-in and S/PDIF out.

Power delivery and chassis support are practical for typical workstation or small business deployments: standard 24-pin ATX and 8-pin EPS connectors, CPU fan and three chassis fan headers, a TPM header and a Thunderbolt header for optional high-speed connectivity. The board also includes a Back-to-BIOS button, RGB LED header and SATA cables in the package.

Suggested use cases include a reliable office or small business PC with manageability features, a content-creation workstation leveraging fast DDR5 memory and NVMe storage, or a mid-range gaming rig where PCIe Gen4 lanes and HDMI 2.1/DisplayPort 1.4 outputs are useful. Windows 10 and Windows 11 are supported out of the box.

Key selling points are clear: AM5 support for Ryzen 7000, DDR5 up to 128 GB with ECC compatibility, dual M.2 plus SATA RAID capability, 2.5 Gb Ethernet, modern USB Type-C and ample expansion slots, all packaged in an ATX motherboard designed for stable everyday performance.
