ASUS TUF Gaming B660M Plus DDR4 Intel Motherboard

The ASUS TUF Gaming B660M-Plus DDR4 is a microATX motherboard built around Intel's B660 chipset, designed to pair with 12th Gen Intel Core, Pentium Gold, and Celeron processors via the LGA1700 socket. Its compact 24.4 cm × 24.4 cm footprint makes it well-suited for space-efficient gaming rigs without sacrificing connectivity or feature depth. On the performance side, the board delivers a PCIe 5.0 x16 primary slot driven directly by the 12th Gen CPU, ensuring headroom for current and near-future graphics cards. A secondary PCIe 3.0 x16 slot (running at x4) and a PCIe 4.0 x1 slot round out expansion options. Storage is handled by two M.2 Key-M slots — both supporting PCIe 4.0 x4 — complemented by four SATA 6 Gb/s ports with RAID 0/1/5/10 support via Intel Rapid Storage Technology. Memory capacity reaches up to 128 GB across four DIMM slots, with DDR4 frequencies from 2133 MHz up to 5333 MHz (OC) and support for Intel XMP profiles and ASUS OptiMem II for tuning stability. The onboard Realtek 2.5 Gigabit Ethernet (protected by TUF LANGuard ESD safeguards) provides a tangible networking advantage over standard 1 GbE implementations, while the onboard Wi-Fi module and rear antenna add wireless flexibility. Audio is handled by a Realtek 7.1 Surround Sound HD codec with audio shielding, dedicated PCB layers, premium capacitors, a power pre-regulator, and a rear optical S/PDIF output — supporting up to 24-bit/192 kHz playback for clear, positional in-game sound. The rear I/O panel offers one USB 3.2 Gen 2×2 Type-C port (up to 20 Gbps), four USB 3.2 Gen 2 Type-A ports, one USB 3.2 Gen 1 Type-A port, and two USB 2.0 Type-A ports alongside DisplayPort 1.4 (4K@60 Hz) and HDMI 2.1 (4K@60 Hz) outputs for integrated graphics. Internal headers add further USB expansion, three addressable Gen 2 ARGB headers, one AURA RGB header, and a Thunderbolt header. Thermal management includes a VRM heatsink with DIGI+ VRM digital power delivery using DrMOS, a flexible M.2 heatsink, and five fan/pump headers (CPU Fan, CPU OPT, AIO Pump, and three chassis headers) controllable via Armoury Crate's Fan Xpert 2+ utility. ASUS Q-Design features — M.2 Q-Latch, Q-DIMM, Q-LED diagnostic LEDs, and Q-Slot — simplify installation, making this board approachable for first-time builders and experienced system integrators alike.
