What customers say
Professional users highly value the ASUS W790-ACE Pro WS for its exceptional build quality and stability under heavy loads with Xeon processors. The robust power delivery and effective cooling are consistently praised, ensuring reliable performance for intensive computing and content creation. Connectivity is a major strength, featuring ample PCIe 5.0 lanes and high-speed M.2 slots, future-proofing the platform. The BIOS offers necessary granular control for professional tuning. While the feature set justifies a premium, the extremely high price point is the main drawback, positioning this board as a necessary, costly investment for mission-critical workstation environments rather than an accessible option.
Know before you buy
This motherboard features the LGA4677 socket and is specifically designed to support Intel Xeon W-3400 and W-2400 series processors.
No, this board requires DDR5 ECC Registered memory. It features eight DIMM slots and supports up to 2048GB of memory, which is essential for the stability required in professional workstation environments.
The board includes five PCIe 5.0 x16 slots, providing significant flexibility for multiple high-end GPUs, storage controllers, or networking cards.
In addition to four SATA 6Gb/s ports, the board offers two M.2 slots for high-speed NVMe SSDs and three SlimSAS ports, which are ideal for connecting enterprise-grade storage arrays.
The W790-ACE uses the CEB form factor, measuring 12 inches by 10.5 inches. You should verify that your case supports CEB dimensions before purchasing, as it is slightly wider than a standard ATX board.
The motherboard is equipped with dual networking options: one 10Gb Ethernet port for high-bandwidth data transfers and one 2.5Gb Ethernet port for standard high-speed connectivity.
Yes, the board includes ASUS BIOS FlashBack technology. This allows you to update the BIOS using only a power supply and a USB drive containing the firmware file, even without a processor or memory installed.
