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 B660 provides users and PC DIY builders a range of performance tuning options via intuitive software and firmware features.ASUS PRIME B660M-A WIFI D4 offers a sleek. futuristic-looking build with a black and white finish. space-shuttle-inspired design elements. metallic nameplate and PCB cover.FLEXIBILITYComprehensive 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.Intelligent ControlAll-Around Energy EfficiencyThe 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.Flexible Air- and Liquid-Cooling ControlsASUS Fan Xpert 2+ software provides comprehensive control over fans. water pumps and all-in-one (AiO) coolers. Whether cooling with air or water. an Auto-Tuning mode intelligently configures all parameters with a single click. There s also an Extreme Quiet mode that reduces all fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans. water pumps and AiO coolers can also be controlled via the UEFI BIOS.Precise Digital Power ControlThe 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.UEFI BIOSThe 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 TweakersAn 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 SetupEZ 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.AI OverclockingEnable AI Overclocking via a shortcut.Intuitive Graphical Fan ControlFine-tune individual fan settings simply by dragging a curve with the mouse.Aura On/Off Mode (Stealth)Easily enable or disable Aura RGB lighting or every onboard LED. for a subdued aesthetic touch.COOLINGPrime 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.HeatsinksM.2 HeatsinkM.2 heatsink wards off throttling that can occur with M.2 storage during sustained transfers. The heatsink is held in place by captive screws.VRM Heatsink and Thermal PadVRM heatsink and thermal pad improve heat transfer from the MOSFETs and chokes for better cooling performance.Cooler by DesignPrime B660 series feature comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.Multiple Temperature SourcesEach 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.Smart ProtectionA dedicated integrated circuit protects each fan header from overheating and overcurrent.4-Pin PWM/DC FanEach onboard header supports auto-detection of PWM or DC fans.PERFORMANCEPrime 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.Robust Power DesignStable power is essential to extract every last bit of performance out of 12th Generation Intel processors. PRIME B660M-A WIFI D4 is geared to cater to the demands of these high-core-count CPUs.ProCool ConnectorProprietary 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 5333(OC)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.ASUS OptiMem IIRevisions to the moth.
