ASUS Pro WS W790E-SAGE SE Workstation Motherboard (LGA 4677, EEB)

Description

Overview

The ASUS Pro WS W790E‑SAGE SE is a server‑grade workstation motherboard in SSI EEB form factor built for Intel Socket LGA4677 (Xeon W‑3400 and W‑2400 series). It offers large memory capacity, abundant PCIe 5.0 expansion and high‑speed networking for professional workstation and single‑socket server workloads where memory density, I/O and reliability matter.

Key features

• CPU: Intel Socket LGA4677 — supports Intel Xeon W‑3400 and W‑2400 series processors (refer to ASUS CPU support list for specific SKUs).
• Chipset: Intel W790.
• Memory: 8 x DIMM slots, 8‑channel DDR5 Registered ECC; up to 2048GB (2TB) supported.
• Expansion: Multiple PCIe 5.0 slots (configurations vary by CPU — up to seven x16 lanes with W‑3400 series).
• Storage: 3 x M.2 (two PCIe 5.0-capable with W‑3400 CPUs, one PCIe 4.0 via chipset), 2 x SlimSAS, and 8 x SATA 6Gb/s ports; Intel VROC support (VROC key sold separately).
• Networking: Dual Intel 10Gb Ethernet plus one Realtek 1Gb Ethernet; ASUS LANGuard protection.
• Management & I/O: Server‑grade remote management (AST2600), rear VGA from BMC, multiple USB including USB 3.2 Gen2x2 Type‑C, BIOS FlashBack and Clear CMOS buttons.
• Power & cooling: Robust power delivery with multiple +12V connectors and dedicated PCIe power headers for multi‑GPU setups.

The board is aimed at engineers, creators and enterprises needing a single‑socket platform with very high memory capacity, extensive PCIe 5.0 expansion and professional networking/management features. As with all platform features, some capabilities (PCIe lane counts, M.2 availability and memory speed) depend on the installed CPU and specific configuration — check ASUS support lists and the user manual for compatibility details.
