ASUS Pro WS B850M-ACE SE Workstation Motherboard, AMD AM5, DDR5, PCIe 5.0, 10Gb LAN, IPMI | 90MB1MN0-M0EAY0

The ASUS Pro WS B850M-ACE SE (90MB1MN0-M0EAY0) is designed to bridge the gap between high-end desktop hardware and enterprise server functionality. Unlike standard gaming boards, this workstation-class motherboard emphasizes remote management and 24/7 reliability. It features an onboard Baseboard Management Controller (BMC) and is extensively tested at high temperatures and humidity levels to ensure it can handle the sustained loads of heavy computational tasks.

Key Features
Server-Grade IPMI Remote Management: Equipped with an onboard ASPEED AST2600 BMC and a dedicated 1Gb management LAN port. This allows for out-of-band monitoring and control via ASUS Control Center Express, making it ideal for remote IT management and headless server setups.

Ultrafast Connectivity: Features a PCIe 5.0 x16 slot for next-gen GPUs and dual PCIe 5.0 M.2 slots. It also includes an MCIO connector (PCIe 5.0 x4) and industrial U.2 support for enterprise SSDs.

Dual High-Speed Networking: Includes both a Realtek 10Gb Ethernet port and an Intel 2.5Gb Ethernet port to handle massive data transfers and low-latency network workflows without bottlenecks.

Intelligent AI Solutions: Supports AI Cache Boost, which optimizes the CPU cache and memory pathways to increase Large Language Model (LLM) performance by up to 29%.

Robust Power Design: Features an 8+2+1 power stage configuration rated for 80A each, utilizing high-quality chokes and capacitors designed to resist extreme thermal environments.

ECC Memory Support: Supports up to 256GB of DDR5 ECC unbuffered memory, ensuring data integrity for mission-critical professional applications.

Performance & Reliability
Designed for the most demanding "Zen 4" and "Zen 5" processors, including the AMD EPYC 4005 series, the board uses an 8-layer PCB to enhance heat dissipation. Specialized features like M.2 Q-Latch and ASUS DriverHub streamline the build and maintenance process, while the Thunderbolt (USB4) header provides a future-proof path for 40Gbps external peripherals.

Why This Motherboard Stands Out
The ASUS Pro WS B850M-ACE SE stands out by offering IPMI management on a Micro-ATX AM5 platform. While most AM5 boards focus on gaming aesthetics, this model prioritizes workstation utility and enterprise-level storage flexibility. It is the definitive choice for professionals building compact AI development machines or high-speed small-business servers.
