ASRock TRX50 WS

The TRX50 WS is ASRock's workstation offering for Threadripper PRO 7000 WX-series builds, distinguishing itself with SlimSAS and MCIO expansion ports that let professionals add extra M.2 storage or PCIe devices beyond the board's built-in slots.

ASRock does not officially disclose an exact phase count or amperage figure for this board's VRM, though the E-ATX layout and heatsink design are built to sustain the power draw of Threadripper PRO WX-series chips under prolonged multi-threaded workloads. Four DDR5 ECC R-DIMM slots run in quad-channel mode, supporting up to 1TB of total system memory for large-scale workstation applications. Five PCIe 5.0 x16 slots provide extensive expansion capacity, and two onboard PCIe 5.0 M.2 slots are supplemented by SlimSAS/MCIO ports that allow additional M.2 or PCIe devices to be connected via an add-in card, a flexible approach to storage expansion. Dual networking is handled by a 10GbE controller alongside a 2.5GbE port, with integrated Wi-Fi 6E covering wireless needs. The extended-ATX form factor (12x10.9 inches) requires a case built for workstation-class boards. Against the Gigabyte TRX50 AI TOP in this catalog, the TRX50 WS's SlimSAS/MCIO expansion ports give it more flexible storage scaling, while the AI TOP instead focuses its differentiation on USB4 and AI-workload tuning utilities.
