Triple M.2

Trusted Stability

Multi-GPU support

Fully loaded takes on new meaning when you have up to 48 PCI Express® lanes and those lanes can be split in a 3-way x16/x16/x8 configuration spanning the board's trio of PCIe x16 slots, allowing you to load up on GPUs to accelerate an increasingly diverse array of workloads, including AI training, 3D rendering, and scientific or financial modeling.

ASUS 2-WAY VGA holder

User-friendly design

The Pro WS C422-ACE is packed with an exclusive two-way VGA holder to provide extra rigid support for up to two high-end graphics cards, to prevent potentially damaging bowing or bending. This VGA holder is easy to install and can be mounted with an additional system fan (up to 120mm), making sure your workstation has ample cooling to complete any task.

*Recommended maximum graphics card size: up to 12.90 x 5.90cm (length x depth)

Power delivery enhancements

Pro WS C422-ACE provides stable power delivery to ensure optimal performance with the latest 18-core Intel® Xeon® W Processors.

8-layer PCB design

ProCool II power connector

The latest ProCool II is an enhanced EATX 8-pin power connector that offers higher endurance and longer lifespan by lowering impedance to prevent hotspots and connector failure. The new design includes upgrades to metal amour and solid pins for better dissipation, as well as a warning LED display with a BIOS POST message to indicate an improper connection.

Enhanced Solid Pin

10A

Last-gen Hollow Pin

Power stages with IR3555 design

The CPU VRM on Pro WS C422-ACE employs a 12+2 power stage design with IR3555, combining high-side and low-side MOSFETs and drivers into a single package, delivering the power and efficiency that high core count processors demand.

Alloy chokes

The Pro WS C422-ACE series uses efficient alloy chokes and high-quality thermal pads to help transfer heat from the VRM array to a sink with ample surface area for the processors.

Durable capacitors

Durable capacitors are engineered to resist extreme temperatures and provide up to 110% better performance than the industry standard.

8-layer PCB design

Multiple PCB layers shift heat away from critical components, providing more headroom to push your CPUs beyond stock speeds.

Tune it your way

Triple M.2

With x4 PCI Express 3.0 bandwidth, Pro WS C422-ACE comes with three onboard M.2 slots — including one vertical slot — that support up to 32Gbps data-transfer speeds. The slots feature ultra-efficient, dual heatsinks that reduce M.2 SSD temperatures by up to 18.7°C for optimal storage performance and improved SSD longevity.

Dual U.2

Unleash NVMe storage devices with dual U.2 ports to experience data-transfer speeds of up to 32Gbps and free up a PCIe slot for another expansion card.

Upgrade your RAID

Intel Virtual RAID on CPU (VROC) obliterates PCH-based RAID arrays that are bottlenecked by the 32Gbps limit of the DMI bus, allowing you to utilize CPU PCIe lanes to configure a bootable RAID array that can transfer data at insane speeds. Pro WS C422-ACE supports RAID 0, 1, 5, 10 to provide fault tolerance and improve overall performance.

*A VROC key is required to enable VROC RAID arrays and support RAID 5 and 10, otherwise only RAID 0 and 1 are supported without a VROC key

Trusted Stability

Pro WS C422-ACE provides enhanced features to smooth your IT operations, including comprehensive system protection, 24/7 stability and reliability.

Ultra-efficient MOS & PCH heatsink

Pro WS C422-ACE ensures optimal cooling and system stability for the Intel® Xeon® W Processors. Higher power requirements are balanced by carefully designed heatsinks that carefully balance mass and surface area to maximize thermal dissipation. In addition to the VRM-heatsink array and the heatpipe that's positioned to provide maximum airflow within the chassis, a dedicated heatsink also help to efficiently dissipate heat from the PCH.

24/7 Dependability

Quality reliability test

Optimized for twenty-four seven operations, the motherboard is tested under temperature up to 45°C and humidity up to 80% to ensure it can handle diverse temperature and humidity range of different location.

SafeSlot

Protect your graphics card investment

SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using an insert-molding process, SafeSlot integrates the slot with fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.

Cooler by design

Flexible cooling controls

Pro WS C422-ACE features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.

Each header can be set to monitor and react to three thermal sensors, and Fan Xpert 4 allows you to assign a sensor to monitor the temperature of supported ASUS graphics cards — all to provide optimal cooling during GPU- or CPU-intensive workloads.

Dedicated PWM/DC header for self-contained water-cooling setup, built right in.

Each onboard header supports auto-detection of PWM or DC fans.

A dedicated integrated circuit protects each fan header from over-temperature and over-current.

Server-grade IT management

ASUS Control Center Express

A server-grade IT management software

ASUS Control Center Express is centralized server-grade IT management software that takes just only a few minutes to install and is designed to reduce IT operations costs and improve efficiency. This powerful tool enables IT administrators to manage and control multiple clients in different locations remotely and includes features such as asset management, software deployment and monitoring. ASUS Control Center Express also lets IT staff visualize deployments, facilitating real-time control.
