## Long description

ASUS Prime B660-PLUS D4 motherboard is designed for 12th Generation Intel® processors, offering a balanced combination of stable power delivery, comprehensive cooling options and flexible connectivity. The board includes multiple M.2 slots, PCIe 4.0 support, USB 3.2 Gen 2x2 Type-C, Realtek 2.5 Gb Ethernet and Thunderbolt™ 4 compatibility via an add-on card. Built-in features such as ASUS OptiMem, Digi+ VRM control, Fan Xpert 2+ and an intuitive UEFI BIOS provide tools for system tuning, energy efficiency and reliable daily performance.
Advantages
Prime B660-PLUS D4 provides a robust power design with ProCool connectors and Digi+ digital voltage regulation to ensure stable CPU power. Comprehensive cooling is achieved through onboard heatsinks, M.2 heatsink, VRM thermal pads and multiple fan headers including a dedicated AIO pump header. Memory routing improvements with ASUS OptiMem increase memory stability and frequency margin. Connectivity options include three M.2 slots (up to PCIe 4.0 speeds), PCIe 4.0 x16 for GPUs, fast USB Type-C ports and support for Thunderbolt™ 4 via an add-on card. User-friendly firmware and software tools such as UEFI BIOS, AI Overclocking, Fan Xpert 2+ and Armoury Crate simplify setup, tuning and RGB control.

How to use
Install the motherboard into a compatible ATX case following standard PC-building procedures: secure the board to standoffs, connect the ProCool 8-pin power connector and the 24-pin ATX power, install CPU and compatible DDR4 modules, and mount cooling solutions including AIO or air coolers. For storage, populate the M.2 slots and SATA devices as required, noting M.2 slot bandwidth limitations. Configure fan curves and pump settings via Fan Xpert 2+ or the UEFI BIOS; enable Auto-Tuning or Extreme Quiet modes as needed. Use the UEFI BIOS for initial setup, EZ Mode for guided configuration, or Advanced Mode for fine tuning, including AI Overclocking and Digi+ voltage adjustments. Install Armoury Crate to manage RGB lighting and device settings, and add the ThunderboltEX 4 card if Thunderbolt™ 4 functionality is desired.
Recommendations
For best results, use a high-quality 8-pin PSU connector and a power supply that meets the power demands of 12th Gen CPUs; ensure adequate case airflow and configure fan profiles to match workload types. When populating multiple M.2 drives, consult the motherboard manual for slot bandwidth sharing and BIOS settings to avoid reduced speeds. Keep firmware and Armoury Crate software up to date for stability and compatibility.
