What reviewers say
Asus Pro WS TRX50-SAGE WIFI A Workstation Motherboard
Owner reports on this board focus on its stability under sustained workstation loads and its deep connectivity, with the main complaints being price and the size of the platform. Reception is limited because the sTR5 workstation audience is small.
- Stable under long rendering and compute runs
- Plenty of PCIe 5.0 lanes for multiple GPUs
- Strong VRM cooling and heatsink coverage
- Useful remote management through IPMI and Control Center Express
- High total platform cost
- E-ATX size limits case choices
- IPMI requires a separate expansion card
Questions and answers
- Which is better for a multi-GPU workstation?
- The ASRock WRX90 WS EVO. It has seven PCIe 5.0 x16 slots versus three on the Asus, so it fits more GPUs at full bandwidth.
- Do I need the ASRock if I only run one GPU?
- No. The Asus covers one or two GPUs plus add-in cards and adds Wi-Fi 7 and USB4 for less money.
- Which supports more CPUs?
- The Asus. It takes Threadripper PRO 9000 and 7000 WX plus standard Threadripper 9000 and 7000. The ASRock lists only Threadripper PRO 7000 WX.
- Is the ASRock worth the extra $169?
- Only if you need seven x16 slots, eight memory channels, or onboard IPMI. For most single-GPU builds the Asus is the better value.
- Which has better remote management?
- The ASRock, with an onboard ASPEED AST2600 BMC and a dedicated IPMI LAN port. The Asus needs an optional IPMI expansion card.
- Which is better for a headless server build?
- The ASRock, because IPMI is built in. The Asus works too but requires the add-in card for out-of-band management.
