Durable capacitors

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

ASUS OptiMem

Proprietary Memory Design

ASUS OptiMem preserves memory signal integrity by routing traces and vias to the optimal PCB layer, and our T-Topology trace layout ensures time-aligned signaling by balancing trace lengths between memory slots.

Multi-Card support

Pro WS C246-ACE features three PCIe x16 slots for flexible expandability with graphics, RAID and LAN cards

Dual Intel server-class Gigabit LAN

Pro WS C246-ACE features the latest server-class dual Intel Gigabit LAN ensuring lower CPU utilization and temperatures outstanding performance as well as better support for diverse operating systems. The dual Ethernet ports also support teaming which combines the network links to provide higher throughput or redundancy in case of failure.

ASUS Control Center Express

A server-grade IT management software

ASUS Control Center Express is centralized server-grade IT management software that takes just one minute 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.

Armoury Crate

The new Armoury Crate portal keeps you updated with the latest drivers and BIOS releases. Its easy-to-use UI can be configured to show a variety of information, including security updates and bug patches.

Cooler by design

Flexible cooling controls

Pro WS C246-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.

M.2 & U.2

Speed up with onboard M.2 & U.2

Pro WS C246-ACE features up to 32Gbps M.2 and U.2 for faster data-transfer speeds ideal for an operating system or application drive.

USB 3.2 Gen 2 back-panel connectors

Future-proof connectivity

The back panel of the Pro WS C246-ACE features four USB 3.2 Gen 2 connectors, including one reversible Type-C and three backward-compatible Type-A to deliver ultimate connection flexibility and blazing data-transfer speeds of up to 10Gbps.

Trusted Stability

Pro WS C246-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 C246-ACE ensures optimal cooling and system stability for both Intel Xeon and Core processors. Higher power requirements are balanced by carefully designed VRM-heatsinks array and a PCH heasink that carefully balance mass and surface area to maximize thermal dissipation

24/7 Dependability

Quality reliability test

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


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.


A header to keep ahead

The ASUS Node connector features a bi-directional interface that offers all kinds of potential for DIY components and builds. The included ASUS Fan Extension Card II connects via Node, and In Win is developing a compatible OLED panel that fits into a chassis and offers LiveDash functionality and the ability to boot directly to the UEFI. FSP has also created a HydroDPM 1000W PSU that connects to Node to share power stats and temperature information while also enabling CPU fan control.

Intel Optane memory
