ASUS Prime series motherboards are expertly engineered to unleash the full potential of 12^th Generation Intel^® processors. Boasting a robust power design, comprehensive cooling solutions and intelligent tuning options, Prime B660 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.

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.

M.2 Heatsink

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.

Cooler by Design

Prime B660 series feature comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.

Multiple Temperature Sources

Each header can dynamically reference three thermal sensors. Fan Xpert 2+ 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 12^th 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.

Robust Power Design

Stable power is essential to extract every last bit of performance out of 12^th Generation Intel processors. Prime B660-PLUS D4 is geared to cater to the demands of these high-core-count CPUs.

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.

DDR4 5066(OC)

Improvements to trace routing design provide the latest Intel processors with enhanced access to memory bandwidth. ASUS OptiMem technology carefully maps memory signal pathways across different PCB layers to reduce path distance, and it adds shielding zones that significantly reduce crosstalk.

Storage

Three M.2 slots (up to 64 Gbps)

Prime B660-PLUS D4 offers a total of three 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.
* The M.2_1 and M.2_2 support PCIe4.0x4, M.2_3 supports PCIe4.0 x2

Connectivity

PCIe^® 4.0 Slot

Prime B660 motherboards are designed specifically for 12^th Generation Intel^® Core™ CPUs and offer PCIe^® 4.0 connectivity for the latest GPUs. The wide bandwidth and superfast transmission speeds allow you to create feature-rich builds that can handle high loads effortlessly.

Aura Sync

Outshine the Competition

A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs as well as strips and devices connected to the onboard RGB headers — and it can all be synced with an ever-growing portfolio of Aura-capable hardware.

Q-LED

The on-board Q-LED troubleshooting lights give PC builders a quick indicator to confirm that key components ― CPU, RAM, graphics card, storage devices ― are functioning normally during startup.
