ASRock WRX90 and TRX50 Motherboards Threadripper 7000 CPUs

ASRock has announced the WRX90 and TRX50 workstation motherboards for AMD’s Ryzen Threadripper 7000 CPUs, featuring wide connectivity tailored for professional users.

Following an E-ATX form factor measuring 305mm x 277mm, the WRX90 WS Evo and TRX50 WS motherboards come packed to the brim with slots and headers. For starters, both boast 18+3+3 110A phase SPS Dr.MOS design to ensure high performance and reliability on the latest AMD Ryzen Threadripper 7000 and Threadripper Pro 7000 WX-Series processors. These VRMs are actively cooled with heatsinks and respective five and four fans each.

The WRX90 WS Evo and TRX50 WS are made using server-grade ultra-low loss PCB – 12 layers on the TRX50. The former supports up to 2TB of DDR5 ECC RDIMM memory through eight channels, whereas the latter makes do with 1TB via four DDR5 channels.

As expected from a professional board, we find advanced PCIe connectivity, with 144 usable PCIe 5.0/4.0 lanes on the WRX90 and 88 PCIe 5.0/4.0 lanes on the TRX50. The latter comes configured with three PCIe 5.0 x16 slots (one at x8 mode) plus two PCIe 4.0 x16 running in x4 and x8.

But that’s not all. In addition to the massive PCIe count, these boards also include server-grade expansions such as Slim-SAS and MCIO, alongside two M.2 SSD slots – one Gen 5 plus one Gen 4 – for high-speed storage.

ASRock TRX50 - IO

To ensure quick file transfers from the cloud or local NAS boxes, ASRock opted for a Marvell 10 GbE plus Realtek 2.5 GbE LAN, with Wi-Fi 6E and Bluetooth 5.2 ready to take over if needed. The remaining I/O comprises one USB 3.2 Type-C 20Gbps, one USB 3.2 Type-C 10Gbps, four USB 3.2 Type-A 10Gbps, and two USB 3.2 Type-A 5Gbps. Not to forget chassis headers, which add one USB 3.2 Type-C 10Gbps, two USB 3.2 Type-A 5Gbps, four USB 2.0 ports, and audio.

Note that the WRX90 WS Evo swaps the LAN chips for Intel’s X710 dual 10GbE while also supporting remote management via AST2600 BMC server management processor, giving system administrators out-of-band managing and monitoring through an IPMI interface.

ASRock didn’t announce any pricing for these boards.
