ASRock WRX90 WS EVO Threadripper PRO EEB Motherboard
The ASRock WRX90 WS EVO is a workstation motherboard designed for AMD Ryzen Threadripper PRO processors, built for professional rendering, simulation, deep learning and design workloads. It combines server-grade PCB engineering with seven PCIe 5.0 x16 slots and eight-channel DDR5 ECC memory support to handle demanding multi-GPU and storage configurations.
Why this product
7 PCIe 5.0 x16 slots
Deliver full PCIe 5.0 bandwidth to GPUs and add-in cards simultaneously, supporting professional multi-GPU workstations without bandwidth bottlenecks.
8-channel DDR5 ECC memory
Supports up to 2TB of registered ECC memory with automatic error detection and correction, critical for workstation stability under sustained multi-threaded loads.
Server-grade PCB construction
14-layer ultra low loss PCB with 2oz copper improves signal integrity for PCIe 5.0 and memory overclocking in professional environments.
Dual 10 Gigabit LAN plus IPMI
Intel X710 dual 10G networking plus dedicated IPMI port for remote management, essential for data centre and networked workstation deployments.
PCIe 5.0 storage options
Blazing M.2 socket supports PCIe Gen5 drives at 128 Gb/s, plus Gen4 M.2 and SlimSAS connectors for high-speed NVMe RAID configurations.

- SKUASR-4235
- EAN4710483945199
- Supports AMD Ryzen Threadripper PRO 9000 and 7000 WX-series processors on Socket sTR5.
- Accepts standard ATX power supplies with 24-pin main power and 8-pin CPU connectors; ErP/EuP ready for energy-efficient PSUs.
- Runs Windows 11 64-bit as primary operating system.
- Supports DDR5 RDIMM and RDIMM-3DS ECC registered memory modules, not consumer unbuffered DDR5.
- EEB form factor (12.0 × 13.0 inches) requires a larger chassis than standard ATX; verify case clearance before purchase.
Best for
- Multi-GPU rendering workstations with NVIDIA or AMD cards needing full PCIe 5.0 bandwidth on each slot.
- Deep learning and AI training platforms requiring high memory capacity and ECC protection across eight channels.
- Data centre and networked workstations leveraging dual 10G LAN and IPMI remote management.
- Storage-intensive NVMe RAID systems with PCIe 5.0 M.2 and multiple SlimSAS connectors for direct-attached storage.
- Professional simulation and CAD workloads needing maximum memory bandwidth and stability under sustained load.
Trade-offs
- Budget builds or single-GPU consumer systems; the EEB form factor and eight-channel memory infrastructure add cost.
- Compact builds; EEB measures 12.0 × 13.0 inches and requires a full-size tower chassis.
- Consumer-grade DDR5 systems using unbuffered UDIMM memory; this board requires registered ECC modules.
- Casual gaming or office work; the Threadripper PRO platform and workstation-class design target professional workflows.
