ASUS Prime TRX40-Pro S
Built for Heavy-Duty Workstations
The ASUS Prime TRX40-Pro S is an ATX motherboard designed for AMD's 3rd Gen Ryzen Threadripper processors (sTRX4 socket). It targets content creators, engineers, and data scientists who need massive multi-core performance and extensive I/O. With eight DDR4 slots supporting up to 256GB in quad-channel mode, it handles memory-intensive tasks like 3D rendering, video editing, and virtual machines with ease.
Key Features
- Powerful VRM: A robust power delivery system with two 8-pin EPS connectors ensures stable operation even under sustained full-core loads. A dedicated fan mount for the VRM heatsink is included for extra cooling.
- PCIe 4.0 Expansion: Three PCIe 4.0 x16 slots (x16, x16/x16, x16/x16/x16) and one PCIe 4.0 x4 slot provide ample bandwidth for multiple GPUs and high-speed add-in cards. Support for 2-way SLI and CrossFire is present.
- Storage Flexibility: Three M.2 slots (one PCIe 4.0 x4/SATA, two PCIe 4.0 x4) plus eight SATA 6Gb/s ports offer extensive storage options. A vertical M.2 mount is included for the third drive.
- Connectivity: Intel I211-AT Gigabit LAN, Realtek S1220 8-channel audio, USB 3.2 Gen 2 Type-C front header, and a pre-mounted I/O shield with BIOS FlashBack for easy updates.
- DIY Friendly: Aura Sync RGB headers, Q-Connector, and a comprehensive accessory package simplify building and customization.
Performance Highlights
In professional reviews, the board demonstrated excellent memory bandwidth, achieving over 87,000 MB/s read and 88,000 MB/s write in AIDA64 with DDR4-3200. Rendering benchmarks like Corona and Fryrender completed quickly, showcasing the platform's strength for multi-threaded workloads. The 8-phase (likely 16+4) power stage delivered stable voltages during overclocking tests.
Who Is It For?
This motherboard is ideal for professionals building a high-end AMD workstation for video production, CAD, scientific computing, or machine learning. It offers a balance of performance, expansion, and reliability without the premium price tag of flagship TRX40 boards. If you need a dependable foundation for a Threadripper-based system, the Prime TRX40-Pro S is a compelling choice.
