Asus Prime B660M-A D4 - Micro ATX - LGA 1700 - DDR4 - Black - Motherboard

Asus Prime B660M-A D4 - Micro ATX lands as a versatile LGA 1700 motherboard designed for 12th/13th Gen Intel platforms and DDR4 memory support.

This micro ATX board combines the Intel B660 chipset with a robust layout that supports a wide range of Intel processors including Intel® Celeron®, Pentium® Gold and the Core™ i3, i5, i7 and i9 families on the LGA 1700 socket. It supports a single CPU and offers compatibility that makes system upgrades straightforward.

Memory capability is a key strength: four DIMM slots support up to 128 GB of DDR4 dual-channel memory and a very broad range of memory speeds up to 5333 MHz (OC). The board accepts Non-ECC DDR4-SDRAM and delivers flexibility for both budget and performance builds.

Storage and expandability are well covered with two M.2 slots, four SATA III ports and support for up to six drives in total, plus RAID 0/1/5/10. For graphics and add-in cards you get two PCIe x16 Gen3 slots and one PCIe x16 Gen4 slot, making this board suitable for multimedia, gaming and workstation tasks in a compact footprint (244 x 244 mm).

I/O and connectivity include Gigabit Ethernet (RJ-45), multiple USB ports (including USB 3.2 Gen 1 Type-C), HDMI (2) and DisplayPort outputs, PS/2 legacy support, and audio driven by the Realtek ALC897 codec with 7.1-channel output. There is no onboard Wi‑Fi, but the board provides a TPM header and RGB LED pin header for system personalization and security.

Cooling is passive for chipset components and the board includes multiple fan connectors (CPU, power fan and two chassis fan headers) as well as standard 24-pin ATX and 8-pin EPS power connectors. BIOS is UEFI AMI with 128 Mbit memory and Windows 10/11 support, simplifying setup and compatibility.

Typical use cases include compact gaming rigs, home office or content-creation PCs where a balance of modern CPU support, multiple storage options and strong memory capacity matter. The Asus Prime B660M-A D4 is a practical choice for users who want upgrade paths without moving to DDR5.
