ASUS Pro WS W790-ACE Workstation Motherboard, Intel LGA4677, Xeon W-2400 & W-3400 Support, DDR5 ECC, PCIe 5.0, Dual 10G LAN | 90MB1C70-M0EAY0

Low-profile professionalism
With metallic black aluminum extrusions, stainless steel black mesh with highlighted details, and a transparent smoky gray I/O cover, Pro WS W790-ACE presents a professional, low-profile look for content creators.​

Multi-GPU support
The Pro WS W790-ACE features five PCIe 5.0 x16 slots for high-powered graphics cards, enabling enhanced performance for professional design, modeling, simulation and rendering applications.

8-pin power connector
Additional PCIe 8-pin power connector can add power output stability when creators and developers use multiple graphics cards.

Reliability with supreme memory overclocking
The Pro WS W790-ACE supports 4-channel 2DPC DDR5 RDIMM ECC memory, allowing automatically to detect and correct data corruption, reducing the chance of system crashes. Being infused with deliberate memory trace layout, this motherboard enables DDR5 memory overclocking with maxed-out speeds to provide better memory performance for a diverse range of workloads.

The ASUS Pro WS W790-ACE (90MB1C70-M0EAY0) is built to handle the most demanding computational tasks. Designed for professionals in architecture, data science, and film production, this motherboard unlocks the full potential of Intel’s latest Xeon W series. It offers the stability and scalability required for 24/7 operation, ensuring that your most complex projects are processed without interruption.

Memory & Storage: Error-Correction & Massive Bandwidth
Precision is non-negotiable in professional environments. The W790-ACE supports up to 2TB of DDR5 ECC RDIMM memory, ensuring that data corruption is caught and fixed at the hardware level. For storage, the board features triple M.2 PCIe 5.0/4.0 slots and dual SlimSAS connectors, allowing for vast, high-speed storage arrays that can keep up with massive datasets and high-bitrate video files.

Expansion: PCIe 5.0 and Multi-GPU Readiness
Equipped with five PCIe 5.0 x16 slots, this motherboard is ready for the most advanced hardware configurations. It supports multi-GPU setups with high-bandwidth lane distribution, making it ideal for GPU-accelerated rendering (Octane, Redshift) and deep learning workloads. The physical slots are reinforced with ASUS SafeSlot technology to securely hold heavy professional graphics cards.

Connectivity: Dual 10G LAN & Remote Management
Networking is optimized for high-speed file transfers with dual Marvell AQC-113C 10Gb Ethernet ports, allowing for rapid movement of assets across a local network or NAS. Additionally, the board features ASUS Control Center Express, providing IT administrators with a centralized dashboard for remote system monitoring, BIOS updates, and security management.

Why This Workstation Board Stands Out
Server-Grade Power Delivery: 12+1+1 power stages with massive heatsinks for maximum stability.

Xeon W-Series Optimization: Tailored specifically for the LGA4677 socket ecosystem.

ECC RDIMM Support: Essential for mission-critical tasks where system crashes are not an option.

Advanced Cooling: Integrated M.2 heatsinks and multiple PWM fan headers for comprehensive thermal control.
