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.
12+1+1 Power stages
Pro WS W790-ACE's VRM is comprised of 12+1+1 power stages, and delivers the power and efficiency that the latest Intel processors demand.
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.
10G & 2.5G Ethernet
One Marvell AQC113CS 10G Ethernet is ready for network attached storage (NAS) and one Intel I226-LM 2.5G Ethernet port is ready for streaming or file upload.
USB 3.2 Gen 2 x 2 Type C
The latest USB standard doubles transfer bandwidth by opening a second USB 3.2 lane, achieving a maximum throughput of up to 20 Gbps. In addition to blazingly fast data-transfer speeds, USB 3.2 offers easy connectivity and ultimate flexibility via USB-C ports.
Two M.2
The Pro WS W790-ACE features two M.2 slots wired for PCIe 4.0 bandwidth. Creators working with massive video files can assemble multiple NVMe drives in a RAID formation for massive I/O bandwidth and seamless playback in their editing bays. Two of these M.2 slots rest under dedicated heatsinks to prevent SSD throttling under heavy loads, and they feature ASUS Q-Latch for easy drive installation and replacement.
More storage
To connect even more high-speed storage, onboard SlimSAS slots let you connect industrial SSDs – not to mention server and networking equipment – through the fast PCIe 4.0/PCIe 3.0 interface.
Remote Management
This motherboard supports remote management with ASUS IPMI expansion card, bringing the benefits for applications that ask for high-performance systems, yet sufficiently and remotely monitoring system status and able to provide real-time troubleshooting. Administrators can remotely communicate with client devices to take some corrective actions – such as resetting or power cycling a system.
ASUS Control Center Express
The Pro WS W790-ACE comes with ASUS Control Center Express – a real-time IT monitoring and management software designed for business that improves productivity and enhances security, helping prevent unauthorized access and data leaks.
Massive VRM Heatsinks
Since mass and airflow are critically important, our VRM heatsinks are manufactured with tall and densely packed fins, and are placed on the MOSFETs and chokes to enhance thermal efficiency.
M.2 heatsinks
Two M.2 slots are covered by heatsinks to combat temperature-induced throttling that can affect performance during heavy, sustained storage loads. M.2 backplate blocks on select slot go even further to ensure that you get peak performance from your next-gen drives.
BIOS Flashback
Users can place a BIOS file onto a FAT32-formatted USB drive and simply plug it into the USB BIOS FlashBack port and press a button to update the (UEFI) BIOS. Updates can be made even if memory or CPU aren't present.


Immersive Audio experience
The Realtek S1220A 7.1 audio codec features high quality 120 dB SNR stereo playback output and 113 dB SNR recording input to offer pristine audio quality and is supported by EMI shielding and separate PCB layers for the left and right channels to maintain signal integrity.
  • Power pre-regulator – Reduces power-input noise to ensure consistent performance.
  • Audio shielding – Separates analog/digital signal domains, significantly reducing multi-lateral interference.
  • Integrated amplifier – Capable of driving high-impedance headphones, without rolling-off high or low frequencies.
  • Separate layer for left and right tracks – Ensures minimal crosstalk between audio paths.
  • De-pop circuit – Reduces start-up popping noise to all audio outputs.
  • Premium audio capacitors – Premium parts provide an immersive sound signature, with exceptional fidelity.
Solid compatibility validation
Pro WS W790-ACE has been extensively tested and validated under various environments and applications for compatibility and reliability.
