Remote Console (ACCE Service)

• Client with BMC (Onboard) - In-band and out-of-band
• Client without BMC - In-band only

ASUS Control Center Express

ASUS Control Center Express is remote IT management software designed for monitoring your hardware and software IT assets and inventory status, with enhanced security and remote control features that prevent data leaks and improve IT operational efficiency.

USB Port Management

Enable or disable the USB port, or set it to Read Only to prevent data leaks.

Software Blacklist

For added security, a software blacklist is available to help prevent the use of high-risk applications.

Registry Editor On/Off

Remotely disable the Registry Editor on client devices to prevent unauthorised changes to system configurations.

The Core of Your Powerful Workstation

Designed to meet the needs of high-core-count CPUs, the Pro WS B850M-ACE SE features 8(80A)+2(80A)+1(80A) power stages that integrate high-side and low-side MOSFETs and drivers into packages rated for up to 80 amps each. This configuration ensures optimal power delivery, efficiency, stability and performance for AMD processors.

Eight-Layer PCB Design

This enhances quick heat dissipation around the voltage regulators for enhanced stability and overclocking.

ProCool II Connectors

These are built to tight specifications to ensure flush contact with PSU power lines. The resulting lower impedance helps to prevent hotspots and connector failure.

Superior Chokes & Capacitors

These are engineered to resist extreme temperatures, providing a higher level of performance than the industry standard.

Digi+ VRM Control

The ASUS Digi+ voltage-regulator module (VRM) is one of the finest in the industry and ensures ultra-smooth power delivery to the CPU.
