Micro-ATX LGA 1700 DDR4 Board

The ASUS PRIME B660M-A AC D4 is a Micro-ATX motherboard built on the Intel B660 chipset with an LGA 1700 socket. It supports 12th and 13th Gen Intel Core, Pentium Gold and Celeron processors for everyday computing, gaming and productivity tasks. Four 288-pin DDR4 slots accept up to 128 GB of memory with overclocking headroom to 5333 MHz.

Check CPU Cooler Clearance And Power Connectors

Verify that your chassis can accommodate the 9.6 by 9.6 inch Micro-ATX form factor and that the CPU cooler mounting holes match LGA 1700. The board requires a 24-pin ATX main power connector and an 8-pin ATX 12V CPU power connector from your power supply. Ensure your case front-panel headers provide a USB Type-C connection if you plan to use the onboard header.

Upgrade From Older B-Series Or H-Series Boards

This board replaces earlier B-series or H-series platforms that lack PCIe 4.0 support and integrated Wi-Fi 5 with Bluetooth 5.1. The jump is worthwhile when you need dual PCIe 4.0 M.2 slots, six SATA 6Gb/s ports with RAID 0, 1, 5, 10, and modern rear I/O including HDMI 2.1, DisplayPort 1.4 and USB 3.2.
