Onboard BMC

The Pro WS B850M-ACE SE workstation motherboard features compatibility with BMC connections, and it is bundled with ASUS Control Center Express software to provide comprehensive in-band and out-of-band management features for businesses and industries.

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.

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.

Memory

The Pro WS B850M-ACE SE motherboard is primed and ready for enthusiast-grade kits, courtesy of vast AMD Extended Profiles for Overclocking (EXPO™) support. You can extract all the potential out of your DDR5 modules, whether they’re from an extreme-speed kit or an entry-level set that would otherwise be locked.

AI Cache Boost

Supercharge your large language model (LLM) workflows with AI Cache Boost. Exclusive to ASUS AMD 800 and 600 series motherboards that use Ryzen™ 9000 Series CPUs, this BIOS setting optimizes CPU cache and memory pathways to deliver up to 29% faster local LLM performance with high-speed memory tuning.

M.2 Q-Latch

The innovative ASUS Q-Latch makes it easy to install or remove an M.2 SSD without the need for specific tools or screws. This design employs a simple locking mechanism to secure the drive and neatly detach it with one tap.

ASUS DriverHub

ASUS DriverHub streamlines the installation and management of ASUS drivers and utilities to keep your hardware up-to-date and perform optimally. This standalone application automatically detects current driver versions and presents available updates in a list view. Users are invited to install ASUS DriverHub after OS installation.

Comprehensive Storage Support

The Pro WS B850M-ACE SE features two PCIe 5.0 x4 M.2 slots, plus one MCIO connector (PCIe 5.0 x4), and one U.2 connector (PCIe 3.0 x4) for industrial-grade U.2 SSD support, delivering exceptional flexibility and high-speed storage options. All M.2 slots support NVMe® RAID configurations to take advantage of the latest available speeds.
