ASUS Control Center Express is compatible with over 100 ASUS motherboards to provide a high-quality, TCO-optimized solution for your business needs.

Secure management of all endpoints.

Secure endpoint configuration management, 'access to portable storage and PC software applications', allowing them to create grouping rules on individual devices.

Flexible control of air and liquid cooling.

ASUS Fan Xpert 2+ software provides comprehensive control over fans, water pumps, and all-in-one (AiO) coolers. Whether air-cooled or water-cooled, an automatic 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 standard minimum to keep the system quiet while performing light tasks. Fans, water pumps, and AiO coolers can also be controlled via the UEFI BIOS.

Heat sink M. 2

The M.2 heatsink avoids the limitation that can occur with M.2 storage during sustained transfers. The heatsink is held in place by captive screws.

VRM heat sink and heating pad

The VRM heatsink and thermal pad improve heat transfer from the MOSFETs and chokes for better cooling performance.

Smart protection

A dedicated integrated circuit protects each fan head against overheating and overcurrent.

4-pin PWM/DC fan

Each integrated connector supports automatic detection of PWM or DC fans.

ProCool Connector

The patented connector enhances the motherboard-to-PSU connection with an 8-pin connector that passes 12 volts of power directly to the processors. Each connector has solid pins that can handle more current than hollow-pin connectors.

DDR4 5333 (OC)

Improvements in trace routing design give the latest Intel processors better access to memory bandwidth. ASUS OptiMem II technology carefully maps memory signal paths across different PCB layers to reduce path distance and adds buffer zones that significantly reduce crosstalk. ASUS OptiMem II technology carefully maps memory signal paths across different PCB layers to reduce vias and adds buffer zones that significantly reduce crosstalk.

Two M.2 slots (up to 64 Gbps)

The PRIME B660M-A D4-CSM offers a total of two M.2 slots that support data transfer speeds of up to 64 Gbps via PCIe® 4.0, allowing for faster loading and startup times for applications with drives or operating system applications.

PCIe® 4.0 slot

PRIME B660 motherboards are specifically designed for 13th and 12th generation Intel® Core™ CPUs and offer PCIe® 4.0 connectivity for the latest GPUs. The wide bandwidth and ultra-fast transfer speeds allow you to create feature-rich builds that can effortlessly handle heavy workloads.

USB 3.2 Gen 1 Type-C®

Numerous USB ports support high-end devices loaded with peripherals, including front-facing USB Type-C® connectors with fast USB 3.2 Gen 1 for transmission speeds up to 5 Gbps.

Gen 2 Addressable Headers

Three Gen 2 addressable headers are capable of detecting the number of LEDs in second-generation addressable RGB devices, allowing the software to automatically adapt lighting effects to specific devices. The new headers also offer backward compatibility with existing Aura RGB hardware.
