Control
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.
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.
Quick and Simple Setup
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.
Intuitive Graphical Fan Control
Fine-tune individual fan settings simply by dragging a curve with the mouse.
EZ XMP
Improve DRAM performance with one click.
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.
Heatsinks
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 options.
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.
Memory
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 to reduce path distance, and it
adds shielding zones that significantly reduce crosstalk.
Storage
Two M.2 slots (up to 64 Gbps)
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.
Connectivity
PCIe® 4.0 Slot
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.
Audio
Combined onboard features deliver elevated audio
Intelligent design and premium hardware create audio quality unlike anything you’ve ever experienced.
Lighting Control
Brighten Up Your Build
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.
DIY Friendly
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.
SafeSlot Core
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.
