  • Low-profile professionalism
    With metallic aluminum extrusions, stainless steel 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 and 2.5G Ethernet
    One Marvell AQC113CS 10G Ethernet is ready for network attached storage (NAS) and one Intel 1226-LM 2.5G Ethernet port is ready for streaming or file upload.
  • USB 3.2 Gen 2x 2 Type-C
    The 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.
  • Front-panel connector
    The front panel USB 3.2 Gen 2x2 connector is ready for next-gen PC cases and devices.
  • Massive VRM heatsinks
    Since mass and airflow are critically important, the VRM heatsinks are manufactured with tall and densely packed fins, and are placed on the MoSFETs and chokes to enhance thermal efficiency.
  • Chipset heatsink
    A dedicated and beefy chipset heatsink draws heat away to maintain optimum operating temperatures.
  • 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.
  • Solid compatibility validation
    PRO WS W790-ACE has been extensively tested and validated under various environments and applications for compatibility and reliability.
  • Protect your graphics cards
    SafeSlot is a PCIe slot reengineered by ASUS to provide optimized attachment and shearing resistance. Manufactured in a single step using the insert-molding process, SafeSlot fortifies the slot with metal for enhanced strength and durability.
  • 24/7 reliability
    Optimized for around-the-clock operations, The ASUS PRO WS W790 series is tested under temperatures of up to 45�C and humidity of up to 80% in order to ensure it can thrive in different environments.

The PRP WS W790 series workstation motherboard is deftly tailored for creative professionals, developers and engineers, unleashing the dominate performance of the Intel Xeon processors, with CPU and memory overclocking capability. Featuring an optimized memory trace layout, advanced power stage design, server-grade IPMI remote management, and ultrafast PCIe 5.0 and networking connectivity, PRO WS W790 series melds no-compromise engineering with incredible aesthetics. ASUS W790 motherboards go above and beyond the ordinary with a painstakingly cultivated collection of hardware validations to help ensure that your workstation build supports a wide variety of memory, cooler, chassis, PSU and other devices.
