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-K D4 provides users and PC DIY builders a range of performance tuning options via intuitive software and firmware features.
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.
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.
ASUS Fan Xpert software provides comprehensive control over fan. There’s an Extreme Quiet mode that reduces fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fan can also be controlled via the UEFI BIOS.
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.
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.
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.
EZ mode displays vital settings and stats and also offers guided wizards, drag-and-drop functionality, and one-click application of important settings — all to help you get your rig up and running in no time.
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 improve heat transfer from the MOSFETs and chokes for better cooling performance.
Prime B660 series feature comprehensive cooling controls that are configurable via Fan Xpert software or via the UEFI BIOS.
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.
The chassis fan header supports auto-detection of PWM or DC fans.
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 options.
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.
Proprietary connectors augment the motherboard's link to the PSU with 8 pin connectors that pass 12 volts of power directly to the processors. Each jack features solid pins that can handle more current than hollow-pin connectors.
A VRM with 6+1+1 Power Stages delivers the power and efficiency that the latest Intel processors demand.
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 to reduce path distance, and it adds shielding zones that significantly reduce crosstalk.
Prime B660M-K D4 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.
* Actual transmission speeds will be lower than the theoretical maximum speed.
Prime B660M-K D4 is designed specifically for 12th Generation Intel® CoreTM CPUs and offer PCIe® 4.0 connectivity. The wide bandwidth and superfast transmission speeds allow you to create feature-rich builds that can handle high loads effortlessly.
Realtek 1 Gb Ethernet reduces CPU overhead and offers exceptionally high TCP and UDP throughput for faster, smoother data transfer.
Prime B660 series add the nuanced details that improve every experience, from exclusive codecs that provide pristine audio quality to intuitive RGB lighting controls that let you customize your system to create a uniquely personal look.
Intelligent design and premium hardware create audio quality unlike anything you’ve ever experienced.
Separates analog/digital signal domains, significantly reducing multi-lateral interference.
Ensures minimal crosstalk between audio paths.
Premium parts provide an immersive sound signature, with exceptional fidelity.
With 5050 RGB strips connected to the RGB header, you can create your own stunning multicolor lighting displays with static, blinking, fading, and strobing effects.
* The RGB-strip header supports 5050 RGB LED strips with a max power rating of 3A (12V). For maximum brightness, strip length should not exceed 3m.
** RGB LED Strips are sold separately.
Armoury Crate is a new software utility designed to give you centralized control of supported products. From a single intuitive interface. The software also provides control of settings for an ever-growing number of ASUS products, including keyboard and mouse preferences. Armoury Crate even features dedicated product registration and news to help you stay in touch with the ASUS community.
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.
SafeSlot Core is the ASUS-exclusive PCIe® slot. Featuring a fortified design that's anchored to the motherboard by a special hook, Safeslot Core provides 1.6X-stronger retention and 1.3X-greater shearing resistance than standard expansion slots.
