Asus PRIME B660M-K D4 Intel Motherboard

FLEXIBILITY
Comprehensive controls form the foundation of the ASUS Prime series. The Prime B660 motherboard packs flexible tools to tune every aspect of your system, enabling performance tweaks to perfectly match the way you work to maximize productivity.

All-Around Energy Efficiency
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.

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 Tuning for Serious Tweakers
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.

COOLING
Prime B660 series are engineered with multiple onboard heatsinks and an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.

VRM Heatsink and Thermal Pad
VRM heatsink and thermal pad improve heat transfer from the MOSFETs and chokes for better cooling performance.

Cooler by Design
Prime B660 series feature comprehensive cooling controls that are configurable via Fan Xpert software or via the UEFI BIOS.

Multiple Temperature Sources
Each header can dynamically reference three thermal sensors. Fan Xpert allows you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.

PERFORMANCE
Prime B660 series are built to handle the additional cores and increased bandwidth of 12th Generation Intel® processors. ASUS B660 motherboards provide all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible transfer option.

Power Design
Stable power is essential to extract every last bit of performance out of 12th Generation Intel processors. Prime B660M-K D4 is geared to cater to the demands of these high-core-count CPUs.
