ASUS Pro WS WRX90E-SAGE SE sTR5 EEB - 90MB1FW0-M0EAY0 Motherboard

ASUS Pro WS WRX90E-SAGE SE is a serious workstation motherboard for sTR5, aimed at Ryzen Threadripper PRO 7000 WX-Series and AMD Ryzen Threadripper Pro 7000. This is a board for high-end configurations where you need a lot of PCIe devices, a lot of RAM, and stability under load for days on end. The AMD WRX90 chipset and EEB form factor make it a typical solution for professional workstations and server cases. You also get serious I/O with USB4, dual 10Gb LAN, and a rich selection of M.2 and SlimSAS options for NVMe.

What you get

The board features 8 memory slots and 4-channel architecture, which means huge overall capacity and high bandwidth – important for 3D rendering, simulations, compilations, and heavy multitasking. The M.2 section is serious: a total of 4 x M.2 slots with PCIe 5.0 x4, plus 2 x SlimSAS ports for PCIe 4.0 x4 NVMe, so you can build a fast local storage array without additional controllers. For expansion slots, you have 6 x PCIe 5.0 x16 plus one more PCIe 5.0 x16 (x8 mode) – this is the territory of multiple GPUs, RAID cards, capture cards, and other professional add-ons. The networking part is also top-notch – Intel dual 10Gb Ethernet with ASUS LANGuard for primary connectivity and a separate Realtek 1Gb Ethernet for management via AST2600. The rear I/O offers modern interfaces like 2 x USB4 (40Gbps), plenty of USB 10Gbps ports, and convenient buttons for BIOS FlashBack and Clear CMOS.

• CPU socket sTR5 supporting Ryzen Threadripper PRO 7000 WX-Series and Threadripper Pro 7000, aimed at professional multi-core configurations.
• AMD WRX90 chipset and EEB form factor, suitable for serious workstation and server-style cases with extended cooling and power capabilities.
• 8 DIMM slots and 4-channel memory, providing high memory bandwidth for rendering, video processing, and heavy professional applications.
• 4 x M.2 PCIe 5.0 x4 slots plus 2 x SlimSAS PCIe 4.0 x4, allowing for the construction of very fast NVMe storage without the need for a separate HBA.
• 6 x PCIe 5.0 x16 slots plus 1 x PCIe 5.0 x16 (x8 mode), providing space for multiple GPUs, professional I/O, and RAID cards.
• Network: Intel dual 10Gb Ethernet + Realtek 1Gb, including a separate 1Gb port for management via AST2600 for easier administration.
• Realtek ALC1220P 7.1-Channel HD Audio with S/PDIF, providing decent built-in sound for professional and multimedia work.
• Rich I/O: 2 x USB4 40Gbps (Type-C), 6 x USB 10Gbps (Type-A), additional front USB 20Gbps/5Gbps/2.0 for modern high-speed peripherals.
• Power supply via 1 x 24-pin + four 8-pin for CPU and additional PCIe, ensuring stability with multi-core CPU and several GPUs under full load.
• Rear panel with mini DisplayPort IN, VGA, BIOS FlashBack and Clear CMOS buttons for easier diagnostics and firmware updates.

Who it is suitable for

This motherboard is for people who are building a serious workstation with Threadripper Pro – 3D, CAD, scientific simulations, virtualization, video production, or multi-GPU workloads. It is also suitable for small studios and teams that want one powerful machine instead of several weaker ones. It is not particularly logical for a typical gaming build or budget configuration – the focus here is purely professional.

The combination of WRX90, the many PCIe 5.0 x16 slots, the rich M.2/SlimSAS options, and dual 10Gb LAN make the ASUS Pro WS WRX90E-SAGE SE a solid foundation for a workstation that won't feel cramped for a long time.
