ASRock WRX90 WS EVO Threadripper Pro PCIe 5.0 SSI-EEB Motherboard

Enterprise-Class Ambition

The WRX90 WS EVO delivers a scale of capability that borders on extravagant, pairing an overbuilt VRM array and reinforced 14-layer PCB with a seven-slot spread of true PCIe 5.0 x16 lanes that can swallow entire fleets of accelerators. Memory headroom stretches deep into high-frequency ECC RDIMM territory, storage branches into Gen5, MCIO and SlimSAS at once, and—refreshingly—USB4 joins the mix to give high-speed externals a rare home on a board built for production-class workloads. Add dual 10GbE, polished lighting control, enriched audio and full IPMI oversight, and you’re looking at a workstation platform created for operations where anything less than excess just wouldn’t cut it.

18+3+3 Power Phase Design

This platform arrives loaded with an 18+3+3 power phase layout backed by 20K capacitors, DrMOS stages and SPS modules, giving the CPU socket the kind of electrical stamina expected from a WRX90-class board. Voltage delivery stays tight across extended workloads, and the component stack helps maintain electrical consistency when you push frequency ceilings or sustain long production cycles.

14-Layer, 2oz Low Loss PCB

A dense 14-layer PCB with 2oz copper forms the backbone of the board, enhancing signal integrity from end to end. The low-loss material keeps data paths steady even as high-speed interfaces ramp up, helping advanced add-in cards and memory channels perform to their potential.

Composite VRM Heatsink with 5 Fans

Thermals are handled by an oversized composite assembly built from XXL aluminium alloy heatsinks fed by five active fans. This cooling setup draws heat away from the VRM array with speed and consistency, keeping temperature drift under control during aggressive CPU tuning or sustained rendering sessions.

Seven PCIe 5.0 x16 Slots

Seven full-length PCIe 5.0 x16 slots open the door to expansive acceleration layouts, from multi-GPU arrays to high-bandwidth storage cards. One slot can be bifurcated into x8 mode when the build calls for flexible lane distribution, giving you more room to architect specialised workflows.

ECC 7600MHz RDIMM & EXPO

Support for ECC RDIMMs up to 7600MHz pairs data integrity with high-frequency throughput. Both standard server-grade reliability and EXPO-driven tuning are available, and DRAM OC support lets you push latency and bandwidth headroom further when the project depends on it.

Multi PSU Adaptor Cable

For systems drawing from more than one power supply, the board includes a low-pin ATX power-on relay. Plug the Multi PSU Adaptor Cable that comes with the package to ATX_CON1 if you use a secondary PSU.

M.2, MCIO & SlimSAS

Storage options span high-speed and high-density formats: Gen5x4 M.2 and Gen4x4 M.2 sockets for blistering solid-state performance; two MCIO connectors offering PCIe Gen5x4 or four SATA3 channels; plus a SlimSAS SFF-8654 connector for PCIe Gen4x4 and another SlimSAS port capable of PCIe Gen4x4 or four SATA3 devices. The layout is geared for heavy project pipelines where throughput matters.

Enhanced with USB 4.0

Two USB 4.0 ports give external devices serious bandwidth for transfers and peripherals. These ports focus on data only, with no display output support, making them ideal for fast portable storage and high-speed accessories.

Intel® X710-AT2 Dual 10GbE LAN

Dual 10GbE ports powered by Intel’s X710-AT2 controller keep network performance sharp and consistent. Large file movements, virtualisation traffic and collaborative production flows move quickly and with dependable stability.

Polychrome ARGB Support

Lighting control is handled through Polychrome ARGB, giving you full command over connected LEDs and chassis elements. It’s a straightforward way to sync colours, set patterns and bring visual character to a workstation-grade build.

Nahimic Audio

Nahimic enhances the onboard audio path with spatial tuning, clear voice pickup and adaptive sound shaping—making games feel more responsive and creative work more immersive. From deep frequency handling to crisp positional cues, it adds welcome depth to everyday listening.

ASPEED AST2600 BMC IPMI

Remote management comes via the ASPEED AST2600 BMC, delivering IPMI control for monitoring, troubleshooting and headless access. It’s built for environments where dependable oversight is essential, giving you full command of system health and management tasks.
