Utilizing the power of 12th Gen Intel processors, you can experience enhanced speeds with PCIe 4.0 technology, providing performance boosts to M.2 SSD and graphics card performance.
Built on the Intel B660 chipset, you have access to an LGA 1700 socket, providing compatibility with a wide range of 11th and 12th gen Intel processors. Four DDR4 channels allow you to install up to 128GB of memory for multitasking performance. Expand your system storage thanks to two M.2 PCIe slots and four SATA III connections. Install a dedicated graphics card into the PCIe 4.0 x16 slot and utilize the two PCIe 3.0 x16 slot for other expansion cards. Multiple USB ports allow you to connect various peripherals such as external drives and keyboards or mice with ease. Connect to a wireless network thanks to the integrated Intel Wi-Fi 6 (802.11ax) or make a wired connection with the Gigabit Ethernet port. Connect to a display thanks to the HDMI and DisplayPort outputs.
Performance Features
ProCool Connector
A proprietary connector augments the motherboard’s link to the PSU with an 8-pin connector that passes 12 volts of power directly to the processor and uses 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 II
Revisions to the motherboard’s trace routing provide the latest Intel processors with unrestricted access to memory bandwidth. ASUS OptiMem II technology carefully maps memory signal pathways across different PCB layers to reduce vias and adds shielding zones that significantly reduce crosstalk.
Two M.2 Slots
The Prime B660M-A WIFI D4 features two M.2 slots that support data-transfer speeds of up to 64 Gb/s via PCIe 4.0, enabling quicker boot-up and app-load times with OS or application drives.
PCIe 4.0 Slot
Prime B660 motherboards are designed specifically for 12th 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.
USB 3.2 Gen 1 Type-C
Numerous USB ports support high-end rigs loaded with peripherals, including front USB Type-C connectors with fast USB 3.2 Gen 1 for transmission speeds of up to 5 Gbps.
Cooling Features
VRM Heatsink
The VRM heatsink and thermal pad improve heat transfer from the MOSFETs and chokes for better cooling performance.
M.2 Heatsink
The 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.
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.
Smart Protection
A dedicated integrated circuit protects each fan header from overheating and overcurrent.
4-Pin PWM/DC Fan
Each onboard header supports auto-detection of PWM or DC fans.
Versatility Features
Energy Efficiency
The Energy Processing Unit (EPU) automatically optimizes power consumption and maximizes energy savings with Away mode, a smart setting that creates an energy-saving scenario by shutting down unused I/O controllers.
Fan Xpert 2+
ASUS 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 quiet when performing light tasks. Fans, water pumps, and AiO coolers can also be controlled via the UEFI BIOS.
Digi+ VRM Control
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 stability and performance gains.
DIY Friendly Features
Q-LED Core
The Q-LED Core display produces light patterns from the 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 fortified with a one-piece stainless-steel brace that shields the slot to protect it from damage. The metal cover is tightly secured to the slot with hooks, and the entire assembly is firmly anchored to the PCB with strengthened solder points to provide a secure foundation for heavyweight graphics cards.
Customization Features
Aura Sync
ASUS Aura Sync 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.
Addressable Gen 2 Headers
Three addressable Gen 2 headers are capable of detecting the number of LEDs on second-gen addressable RGB devices, allowing the software to automatically tailor lighting effects to specific devices. The new headers also offer backward-compatibility with existing Aura RGB gear.
Armoury Crate
Armoury Crate is a new software utility designed to give you centralized control of supported products. From a single intuitive interface, Armoury Crate allows you to easily customize RGB lighting and effects for every compatible device in your arsenal. The software also provides control of settings for an ever-growing number of ASUS products, including keyboard and mouse preferences.
