Prime B660M-A D4
ASUS Prime series motherboards are expertly engineered to unleash the full potential of 12th Generation Intel processors. Boasting a robust power design, comprehensive cooling solutions and intelligent tuning options, Prime B660M-A D4 provides users and PC DIY builders a range of performance tuning options
Two M.2 Slots
Offers a total of two M.2 slots that support data-transfer speeds of up to 64 Gbps via PCIe 4.0, enabling quicker boot-up and app load times with OS or application drives.
PCIe 4.0 Slot
Offers PCIe 4.0 connectivity. The wide bandwidth and superfast transmission speeds allow you to create feature-rich builds that can handle high loads effortlessly.
DDR4 5333 OC
Improvements to trace routing design provide the latest Intel processors with enhanced access to memory bandwidth. ASUS technology carefully maps memory signal pathways across different PCB layers.
All Around Energy
The Energy Processing Unit (EPU) automatically optimizes power consumption and maximizes energy savings with Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.
Fan Xpert 4
The software provides comprehensive control over fans and all-in-one (AiO) cooler. Whether cooling with air or water, an Auto-Tuning mode intelligently configures all parameters with a single click. The same can be done via UEFI BIOS.
Digi+ VRM Control
The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings. It also allows you to fine-tune your CPU for ultimate stability and performance.
USB 3.2 Gen 1 Type-C
Numerous USB ports support high-end rigs loaded with peripherals, including front USB Type-C connectors with fast USB 3.2 Gen 1 for transmission speeds of up to 5 Gbps.
SafeSlot Core+
ASUS-exclusive PCIe slot fortified with a one-piece stainless-steel brace that shields the slot to protect it from damage
Addressable Gen 2 Headers
3 addressable Gen 2 headers are capable of detecting the number of LEDs on second-gen addressable RGB devices, allowing the software to automatically tailor lighting effects to specific devices.
Q-LED Core
The Q-LED Core display produces light patterns by power LED during the Power-On Self-Test (POST) that can help users troubleshoot potential issues.
