Overview
The ASUS TUF Gaming B660M-E DDR4 is a microATX motherboard built around Intel's B660 chipset, designed to pair with 12th Generation Intel Core, Pentium Gold, and Celeron processors using the LGA 1700 socket. Its compact 24.4 cm x 24.4 cm footprint makes it a practical choice for space-conscious gaming builds without sacrificing connectivity or protection features. Power delivery is handled through a 10-stage power solution paired with Digi+ VRM digital voltage regulation, a six-layer PCB for optimised thermal management, and ASUS ProCool connectors that maintain full contact with PSU cables to reduce impedance and prevent hotspots. Military-grade TUF components underpin the board's long-term stability during extended gaming sessions. Storage options include two PCIe 4.0 x4 M.2 slots (Key M, supporting 2242/2260/2280 form factors) and four SATA 6 Gb/s ports with Intel Rapid Storage Technology support for RAID 0/1/5/10 configurations. Memory capacity reaches up to 128 GB across four DIMM slots, supporting DDR4 speeds from 2133 MHz up to 5333 MHz (OC) with Intel XMP and ASUS OptiMem II. Connectivity is handled by Realtek 2.5 Gb Ethernet protected by TUF LANGuard surge protection, a front-panel USB 3.2 Gen 2 Type-C connector, and a rear I/O panel featuring two USB 3.2 Gen 2 Type-A ports, two USB 3.2 Gen 1 Type-A ports, DisplayPort 1.4 (4K@60Hz), and HDMI 2.1 (4K@60Hz). Audio is managed by a Realtek ALC897 codec delivering 7.1 surround sound high-definition audio with up to 24-bit/192 kHz playback, dedicated audio PCB layers, and Two-Way AI Noise Cancellation via Armoury Crate software. The SafeSlot Core+ PCIe x16 slot features a one-piece stainless-steel reinforcement brace, while SafeDIMM guides simplify memory installation. AURA Sync RGB lighting includes one AURA RGB header and three Addressable Gen 2 headers for ecosystem-wide synchronisation. Fan control is managed through Fan Xpert 2+ with four 4-pin headers (one CPU, one CPU OPT, two chassis). A Wi-Fi module can be added via the rear Key-E V-M.2 slot (sold separately).
