MSI's WS WRX80 motherboard has broken cover in the wake of the AMD Ryzen Threadripper Pro 5000 WX-Series launch yesterday (AMD "Chagall" Zen 3, up to 64 cores). MSI currently isn't listing this motherboard on its official product pages. Still, WCCFTech spotted it and asserts it is a time-limited exclusive for Lenovo systems before heading to the DIY segment. The source has a raft of genuine-looking images and specs, but please add a pinch of salt to the data since this isn't direct from MSI (or Lenovo).

The pictured motherboard will be MSI's first to address AMD Threadripper Pro CPUs and work with both AMD Threadripper Pro 3000WX and new 5000WX CPU families. Befitting the foundation for such a powerful processer, the new MSI WS WRX80 is said to be fully loaded with regard to features and supporting technologies.

Alleged key specs of this E-ATX motherboard, which you wouldn't be able to ascertain from the product photos we have access to, include a 14 layer PCB with 2 oz of copper, 11 dedicated VRM phases using eleven 105A Smart Power Stages, support for up to 2TB of DDR-3200 (ECC and non-ECC) RAM, and overclocking support for both CPU and RAM. Meanwhile built-in networking components are provided for 10G LAN + Gigabit LAN and Wi-Fi 6E. We have tabulated all the specs we can gather below.

MSI WS WRX40 feature


Processor support

AMD Ryzen Threadripper PRO Series Processors for Socket sWRX8.

RAM support

DDR4 ECC and non-ECC DDR4-3200 memory, eight slots for up to 2TB.


Powered by dual 8-pin connectors and a 24-pin ATX connector. Dedicated 11 phases 105A digital power to CPU.


10G LAN + Gigabit LAN, Wi-Fi 6E and bandwidth management.


7x PCIe 4.0/3.0 x16 metal reinforced slots, 2x Lightning Gen4 M.2, 8x SATA connectors, 2x U.2 connectors.


Twin Frozr 0dB tech fan plus heatsink on the chipset, sizable stacked fin heatsinks on VRMs,  and heatsinks for M.2 storage.


E-ATX size, 14-layer PCB, BMC/IPMI remote management via Aspeed AST2600 BMC chip.

Thanks to the 128 PCIe lanes on the platform, all seven PCIe slots can run at up to full x16 speeds. In the photos of the board, you can clearly see an EZ Debug LED as well as on-board power and reset switches to make the setup, testing, and deployment of the board as convenient as possible.

Please remember that this MSI motherboard is said to be a Lenovo system exclusive. However, the source asserts that the MSI WS WRX80 will make it to the DIY market next month, at a "very premium price." The reason for the potential sticker shock isn't just down to the premium and extensive component selection as there is scarcity to consider. If it launches, this will become only the fourth WRX80 board made available to DIYers.

    But, when/if the mainboard launches, will there actually be TR 5000 series CPUs for sale to put in it?

    Very very interesting. The memory layout looks better than Asus pro WS sage. This is the 1 St part of the overclock chain. The second part is memory. I cannot find any RDIMM or LRDIMM or even ECC DIMMs above 3200. Considering that
    DDR4 3600 UDIMMs are both plentiful and cheap.
    The TRX40 is missing, so farI really hope there is at least 1 DDR4- 3600 cas 16 RDIMM ECC module released.
