ASUS Pro B660M-C DDR4 Intel Motherboard

The ASUS Pro B660M-C D4-CSM is a microATX business motherboard built around the Intel B660 chipset and the LGA1700 socket, offering compatibility with 12th and 13th Generation Intel Core, Pentium Gold, and Celeron processors. Designed specifically for commercial and enterprise deployments, it carries ASUS Corporate Stable Model (CSM) program backing, which provides up to 36 months of product lifecycle support and a 6-month end-of-life notification window — giving IT teams the planning runway they need for hardware transitions. Memory configuration is handled by four DDR4 DIMM slots supporting up to 128 GB of non-ECC, unbuffered RAM in a dual-channel architecture. Rated speeds range from DDR4-2133 up to DDR4-4600 (with XMP overclocking), providing flexibility for both standard workloads and performance-sensitive applications. Storage is equally capable: two M.2 Key-M slots (type 2242/2260/2280) deliver PCIe 4.0 x4 bandwidth on supported processors, complemented by four SATA 6 Gb/s ports. In total, up to six storage devices can be connected simultaneously. Expansion is handled by one PCIe 4.0/3.0 x16 slot for discrete graphics alongside two PCIe 3.0 x1 slots for peripheral cards. Display output options on the rear I/O include two DisplayPort outputs, one HDMI port, and one D-Sub (VGA) port, making this board well suited for multi-monitor commercial workstations drawing on integrated graphics. Connectivity on the rear panel includes two USB 3.2 Gen 1 Type-A ports, two USB 2.0 Type-A ports, a PS/2 keyboard port, a PS/2 mouse port, Intel 1 Gb Ethernet with ASUS LANGuard surge protection, and three audio jacks. Internal headers expand USB availability to a total of eleven ports. Wireless and Bluetooth are not built in but can be added via the M.2 Key-E (CNVi/PCIe) slot. Audio is managed by a Realtek 7.1 surround sound High Definition Audio codec supporting up to 24-bit/192 kHz playback. Manageability features include Wake- LAN (WOL) via PME and PXE network boot. A TPM IC is onboard for hardware-level security, and the self-recovering ASUS BIOS with a 128 Mb Flash ROM protects against firmware corruption. The Q-LED diagnostic display, Event Log, COM debug header, and LPT header round out the serviceability toolkit for IT administrators. Each unit ships with ASUS Control Center Express (ACCE) activation, a real-time IT monitoring and management platform licensed per purchase.
