Built around the AMD WRX90 chipset and sTR5 socket, this board fully supports AMD Ryzen Threadripper PRO 9000 and 7000 WX‑Series processors, delivering exceptional multi‑threaded performance for intensive workloads including 3D rendering, video production, CAD/CAM, scientific simulation, AI training, deep learning, server virtualization, and high‑frequency data processing. Whether you are building a dedicated workstation for professional content creation, a compute node for research labs, or a reliable platform for industrial applications, the WRX90 WS EVO combines server‑grade durability, enthusiast‑level overclocking potential, and enterprise‑class connectivity to redefine what a modern workstation can achieve.

Optimized VRM Design: Stable Power for Extreme Workloads

At the heart of the WRX90 WS EVO lies a robust 18+3+3 phase power design with 110A Smart Power Stage (SPS) technology for the VCore, ensuring clean, steady, and efficient power delivery even under maximum CPU load or aggressive overclocking. The board uses long‑life 20K‑hour black capacitors that drastically improve component longevity and system Mean Time Between Failures (MTBF), critical for workstations that run 24/7. ASRock’s Hi‑Density Power Connectors support higher current draw compared to standard connectors, reducing thermal stress and fire risks during heavy overclocking or sustained high‑power operation. The composite VRM heatsink with active cooling fans, oversized aluminum heatsinks, and heat pipes maximizes heat dissipation, keeping voltage regulation modules cool and maintaining consistent performance during prolonged compute tasks. This power architecture not only supports the highest‑end Threadripper PRO processors but also provides headroom for overclocking, making the board suitable for both professional stability and performance tuning.

Server‑Grade PCB and Signal Integrity

The WRX90 WS EVO employs a 14‑layer server‑grade ultra‑low‑loss PCB with 2oz copper inner layers, engineered for superior signal integrity, energy efficiency, and thermal control. The low‑loss design preserves signal quality for PCIe 5.0 devices and high‑speed DDR5 memory, while the thick copper layers lower operating temperatures and improve power delivery efficiency. These features ensure the motherboard reliably supports PCIe 5.0 bandwidth for graphics cards, NVMe SSDs, and expansion cards, while also enhancing memory overclocking potential for extreme memory performance. The multi‑layer PCB isolates power and signal traces, minimizing electromagnetic interference and ensuring stable operation even with multiple high‑power add‑in cards installed. This server‑grade construction makes the WRX90 WS EVO far more durable and reliable than standard consumer motherboards, ideal for mission‑critical workstation environments.

8‑Channel DDR5 ECC Registered Memory Support

Memory stability and capacity are essential for professional workstations, and the WRX90 WS EVO delivers with eight DDR5 DIMM slots supporting eight‑channel ECC Registered RDIMM/RDIMM‑3DS memory up to 7600+ MHz (OC). The board supports a maximum system memory capacity of 2TB, enabling seamless handling of large datasets, virtual machines, complex simulations, and high‑resolution media projects. Error Correcting Code (ECC) technology automatically detects and corrects single‑bit and multi‑bit data errors, drastically reducing system crashes, data corruption, and downtime in professional environments. Whether you are working with massive 3D scenes, rendering 8K video, running database applications, or performing real‑time data analysis, the eight‑channel DDR5 ECC configuration provides the bandwidth and reliability needed to maintain smooth workflow and prevent costly interruptions.

Unmatched Expansion: 7×PCIe 5.0 x16 Slots

The WRX90 WS EVO sets a new standard for expandability with seven PCIe 5.0 x16 slots, offering extraordinary potential for multi‑GPU configurations, high‑speed storage adapters, compute accelerators, RAID controllers, network cards, and professional I/O expansion. Full PCIe 5.0 bandwidth unlocks the full potential of next‑generation graphics cards and accelerator cards used in deep learning, ray tracing, video editing, and scientific computing. The PCIe slots feature 15μ gold contacts for improved signal stability and corrosion resistance, ensuring long‑term reliability even in heavy‑use environments. This level of expansion makes the motherboard suitable for workstations requiring multiple professional GPUs, FPGA accelerators, or high‑port‑count storage and networking cards, catering to the most demanding professional applications.

Ultra‑Fast Storage: PCIe Gen5 M.2 and Server‑Grade Interfaces

Storage speed and scalability are critical for modern workstations, and the WRX90 WS EVO provides a comprehensive array of high‑speed storage options. The board includes one Blazing M.2 slot supporting PCIe Gen5 x4 (128Gb/s) for next‑generation ultra‑fast NVMe SSDs, along with one Hyper M.2 slot supporting PCIe Gen4 x4 (64Gb/s). For enterprise‑level storage expansion, the motherboard features two MCIO connectors (PCIe Gen5 x4 or 4×SATA3) and two SlimSAS SFF‑8654 connectors (PCIe Gen4 x4 or 4×SATA3), supporting high‑capacity SSDs and HDDs for large‑scale data storage, NAS, or SAN configurations. Four legacy SATA3 6.0Gb/s ports are also included for compatibility with standard storage devices. The board supports RAID 0, 1, 10 for both SATA and NVMe storage, allowing users to balance performance, capacity, and data redundancy according to their professional needs.
