## Summary description

ASRock TRX50 WS is an EATX workstation motherboard with AMD TRX50 chipset and Socket sTR5 for compatible AMD Ryzen™ 7000 Series processors. It supports DDR5 quad‑channel memory across four DIMM slots (up to 1 TB, ECC), multiple PCIe x16 slots including Gen5, two M.2 slots (PCIe Gen5/Gen4), dual 10/1G Ethernet ports, abundant USB (Type‑A/Type‑C, Gen2/Gen2x2) and storage interfaces, TPM and wake‑on‑LAN for professional workstation use.

## Long description

The ASRock TRX50 WS motherboard is designed for AMD Ryzen Threadripper PRO 7000 and Threadripper 7000 series processors, offering robust power delivery, advanced connectivity and extensive expansion options for professional workstations. It features long-lasting 20K black capacitors, a Dr.MOS Smart Power Stage (SPS) design, an 18+3+3 power phase layout and Hi-Density power connectors to ensure stable power and enhanced overclocking potential. The board uses server-grade ultra low loss and 12-layer 2oz copper PCBs to improve signal integrity and thermal performance. Memory support includes DDR5 RDIMM ECC across four DIMM slots with up to 1 TB capacity. Expansion and storage are covered by three PCIe Gen5 x16 slots, PCIe Gen5 M.2 support, SlimSAS (SFF-8654) and MCIO server-grade storage connections. Network options include Marvell 10 GbE and Realtek 2.5 GbE plus Wi‑Fi 6E. Additional conveniences include USB 3.2 Gen2x2 Type-C, onboard and addressable RGB headers (Polychrome RGB), Nahimic audio features, Auto Driver Installer, BIOS Flashback and a pre-installed I/O shield.
Advantages
The motherboard delivers stable and efficient power through industrial-grade components—20K capacitors, SPS Dr.MOS design and 18+3+3 phases—reducing thermal stress and increasing MTBF for sustained workloads. Server-grade PCB construction and 2oz copper inner layers enhance signal integrity for PCIe 5.0 and memory overclocking while lowering operating temperatures. Extensive expansion with three PCIe Gen5 x16 slots and PCIe Gen5 M.2 supports high-performance GPUs and ultrafast NVMe storage. Storage and connectivity options are targeted at professional use, with SlimSAS/MCIO storage ports and dual high-speed LAN plus Wi‑Fi 6E for fast transfers. ECC RDIMM DDR5 support up to 1 TB improves data integrity for workstation applications.

How to use
Install a compatible AMD Ryzen Threadripper PRO or Threadripper CPU into the TRX50 socket, populate up to four DDR5 RDIMM ECC modules according to the motherboard manual, and connect the Hi‑Density CPU 8‑pin and ATX 24‑pin power connectors. For multi‑PSU setups, use the Multi PSU adaptor cable and the ATX\_Con header as instructed. Install GPUs or add‑on cards into the PCIe Gen5 x16 slots and mount NVMe SSDs into the PCIe Gen5 M.2 slots or attach storage via SlimSAS/MCIO. Connect network and peripherals through the onboard LAN, Wi‑Fi antenna and USB ports. Use the Auto Driver Installer after OS installation to fetch drivers, and update BIOS via BIOS Flashback if necessary. Configure Polychrome RGB and Nahimic audio from their respective utilities when the system is running.
Recommendations
For stable operation under heavy workloads or overclocking, use a high‑wattage, quality PSU (or dual PSUs via the Multi PSU adaptor), ensure adequate chassis cooling to exploit the 2oz copper and 12‑layer PCB thermal benefits, and employ ECC RDIMM DDR5 memory when data integrity is a priority for workstation tasks.
