MSI XpertStation WS300 brings Nvidia GB300 Blackwell to the desktop

Not for everyday users

Nvidia appears to be deliberately pushing its server-class platforms into desktop form factors as well. MSI has unveiled the XpertStation WS300 - a desktop PC, but one built from data centre components.

MSI XpertStation WS300 on the Nvidia GB300 Blackwell platform

In practice, this is essentially the same concept Dell announced earlier. The system is based on the Nvidia GB300 Blackwell platform, pairing the Nvidia Grace CPU (72 Neoverse V2 cores) with the DGX B300 GPU featuring 288 GB of HBM3E memory. The notable difference is that, unlike Dell’s machine, MSI’s new model does not include a discrete RTX Pro 1000 Blackwell.

Memory, SSD options and the 1600 W power supply

As with the other GB300-based desktops, the WS300 supports up to 496 GB of SOCAMM RAM, although specific configurations may ship with less. There are four slots available for SSDs. Even the power supply matches the template at 1600 W.

Why these near-identical desktops matter

It is clear that, technically, PCs built around this platform can only differ in minor ways, because they all rely on the same Nvidia motherboard. It is likely Nvidia also limits what partners can change - for example, it may not permit a different power supply rating.

For us, that means there is little to separate these systems on a purely technical level, which makes them less compelling as distinct products. The key point is different: multiple companies releasing effectively the same machine suggests this is a deliberate, coordinated rollout led by Nvidia.
