ASUS PRIME B660M-A D4-CSM mATX Motherboard | LGA1700 | 4x DDR4 Slots
Description
The ASUS PRIME B660M-A D4-CSM delivers mainstream Intel performance in a compact micro ATX package. Built on Intel's B660 chipset with LGA1700 socket compatibility, it supports 12th and 13th generation Intel processors from budget-friendly Celeron chips through to high-performance Core i9 models. The board's compact footprint makes it ideal for smaller builds where space matters, while still providing the connectivity and features needed for a capable desktop system.
Memory support centres around DDR4 technology with four DIMM slots supporting up to 128GB of RAM. The board handles DDR4 speeds up to 5333MHz when using XMP profiles, giving you plenty of headroom for both current applications and future upgrades. Storage connectivity comes through two M.2 slots for fast NVMe SSDs, while PCIe 4.0 support ensures compatibility with the latest graphics cards. Integrated graphics outputs include DisplayPort and two HDMI ports for multi-monitor setups without a dedicated GPU.
Connectivity covers both front and rear panel needs with USB 3.2 Gen 2 ports at the back and a convenient USB 3.2 Gen 1 Type-C connector on the front panel. Intel Gigabit Ethernet handles wired networking, while ASUS Aura Sync RGB support adds customisable lighting effects. The board includes standard accessories like the rear I/O shield, SATA cables for storage drives, and mounting hardware for M.2 SSDs. A comprehensive user guide walks you through the installation process and BIOS setup options.
