Overview
The ASRock B660M ITX/AC is a Mini-ITX form-factor motherboard built on Intel's B660 chipset and designed for 12th and 13th Generation Intel Core processors using the LGA1700 socket. At just 17.0 cm x 17.0 cm (6.7-in x 6.7-in), it delivers a surprisingly complete feature set into one of the smallest standard PC form factors available, making it a practical foundation for compact desktop builds, home-office systems, and space-constrained workstations. Power delivery is handled by a 6-phase Dr.MOS design rated at 50A per phase, supporting Intel Hybrid Technology and Intel Turbo Boost Max 3.0 Technology. Two DDR4 DIMM slots accept up to 64 GB of dual-channel non-ECC unbuffered memory with XMP 2.0 support and overclocked speeds up to DDR4 5000 MHz (OC). Storage options are generous for the platform: a CPU-connected Hyper M.2 slot (Key M, type 2280) runs at PCIe Gen4 x4 (up to 64 Gb/s) or SATA3 6.0 Gb/s, while four additional SATA3 6.0 Gb/s connectors on the chipset support RAID 0, 1, 5, and 10 configurations. The single PCIe 4.0 x16 slot handles discrete GPU installations. Display output is provided through an HDMI 2.1 port (up to 4K/60Hz) and a DisplayPort 1.4 port (up to 8K/60Hz compressed via DSC), both driven by the integrated Intel Xe Graphics (Gen 12) architecture when a compatible CPU is installed. Audio is managed by a Realtek ALC897 codec delivering 7.1-channel HD audio with surge protection. Connectivity highlights include an Intel I219V Gigabit LAN controller with Wake- LAN and ESD protection, plus an onboard 802.11ac (Wi-Fi 5) dual-band module supporting IEEE 802.11a/b/g/n/ac frequencies (2.4 GHz and 5 GHz) at up to 433 Mbps, paired with Bluetooth. Two external antenna ports are included on the rear I/O panel. USB ports span USB 3.2 Gen1 (two rear, two front-panel header, one front Type-C header) and USB 2.0 (two rear, two front-panel header), all with ESD protection. The rear panel also provides a PS/2 keyboard/mouse port, RJ-45 LAN port, and HD audio jacks. An addressable LED header enables ARGB lighting via ASRock Polychrome SYNC software. The board ships with ASRock's 128 Mb AMI UEFI BIOS (multilingual GUI, ACPI 6.0, SMBIOS 2.7), A-Tuning software, XFast LAN, and Full Spike Protection across all USB, audio, and LAN ports. In the box: I/O shield, two SATA data cables, two 2.4/5 GHz Wi-Fi antennas, one M.2 mounting screw, support CD, and quick installation guide. The board carries FCC and CE certifications and is ErP/EuP ready. ASRock provides a 3-year warranty.
