ASUS Pro WS TRX50-SAGE WIFI sTR5 workstation

This CEB-form-factor board uses the AMD TRX50 chipset and the sTR5 socket for Ryzen Threadripper PRO 7000 WX-Series and Ryzen Threadripper 7000 Series processors. It targets professional workstations that need high core counts, large ECC memory capacity and server-grade remote management. The 36-stage VRM with dual 8-pin CPU power connectors is built for sustained 24/7 loads.

Suits multi-GPU compute.

Three PCIe 5.0 x16 slots plus one PCIe 4.0 x16 and one x4 give room for multiple accelerators or high-speed add-in cards. Four DIMM slots support up to 1 TB of ECC R-DIMM DDR5 in a four-channel layout. Integrated Wi-Fi 7, 10 Gb and 2.5 Gb Ethernet plus rear USB 20 Gbps Type-C cover fast data movement. Builders needing more than four memory channels or a different socket should evaluate other platforms.

Maximum 1 TB ECC R-DIMM DDR5 capacity

The four-slot, 1 DIMM-per-channel design caps total system memory at 1 TB. Workloads that require more memory per socket must choose a platform with eight or more DIMM slots. This limit is the single specification that decides whether the board fits the target application.

Questions about this item

What comes in the box and what must I source separately?

The motherboard includes the I/O shield, Wi-Fi 7 antenna, SATA cables, M.2 screws and thermal pads, and documentation. You must buy an sTR5 Threadripper CPU, ECC R-DIMM DDR5 modules, storage drives and a CEB-compatible chassis with two 8-pin CPU power connectors.

Which memory capacity should I choose for this board?

The board supports up to 1 TB across four DIMM slots in a 4-channel layout. Populate all four slots with identical ECC R-DIMM DDR5 modules for full bandwidth; capacity per module depends on your workload and budget.

What does the 36 power-stage design mean for daily operation?

Thirty-six power stages fed by dual 8-pin connectors deliver stable current to high-core-count CPUs, while the large VRM heatsinks and M.2 cooling keep temperatures low during sustained 24/7 workloads.
