LGA 1700 Socket
Micro-ATX Form Factor
Tweak and Tune Your Way
Comprehensive controls form the foundation of the ASUS Prime series. The Prime B660M-A motherboard packs flexible tools to tune every aspect of your system, enabling you to tweak performance settings to perfectly match the way you work – maximising your productivity.
ALL-AROUND ENERGY EFFICIENCY
The Energy Processing Unit (EPU) automatically optimises your power consumption and maximizes energy savings with a simple Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down any unused I/O controllers.
World Renowned UEFI BIOS
The renowned ASUS UEFI BIOS provides everything you need to configure, tweak and tune your system. It offers intelligently simplified options for PC DIY beginners, as well as comprehensive features for seasoned veterans.
ADVANCED MODE
An intuitive Advanced mode offered via the UEFI lets you take complete control. A built-in search feature makes it easy to find options, and various Advanced functions let you intelligently make nuanced adjustments so you can dial in performance just the way you want.
Keep your Components Cool for Longer
M.2 heatsink wards off throttling that can occur with M.2 storage during sustained transfers. The heatsink is held in place by captive screws.
Robust Power Design
PROCOOL CONNECTOR
Proprietary connector augments the motherboard’s link to the PSU with 8 pin connector that passes 12 volts of power directly to the processors. Each jack features solid pins that can handle more current than hollow-pin connectors.
New and Improved Storage
Improvements to trace routing design provide the latest Intel processors with enhanced access to memory bandwidth. ASUS OptiMem II technology carefully maps memory signal pathways across different PCB layers to reduce path distance, and it adds shielding zones that significantly reduce crosstalk.
Future Proof Connectivity
PRIME Tried and Tested
ASUS motherboards offer superb endurance verified by subjecting every board to more than 8,000 hours of stringent tests. A barrage of burn-in, environmental, compatibility, software and safety tests confirm that our motherboards are exceptionally robust. It also shows that ASUS reliability surpasses industry standards, ensuring that every component is designed to function flawlessly in any environment.
