MSI broke ranks on Station pricing: an $85,000 MSRP against six-figure siblings, with street pricing observed at $96,995.99 (CDW). No UK sticker exists yet — expect a quote via UK NVIDIA partners.
The build is the full reference platform — 748 GB coherent, dual 400 GbE — with MSI pitching it explicitly at organisations that want frontier-class AI without a cloud dependency.
vs its siblings: Lowest published MSRP of any GB300 Station; shipping now.

Where it shines
- Near-trillion-parameter open weights on one desk, one wall socket
- 252 GB of HBM3e at 7.1 TB/s — data-centre bandwidth, deskside
- MIG partitions one station into up to 7 governed instances
- Dual 400 Gb networking — a real path to multi-station clusters
The trade-offs
- Capital cost of a small fleet of cars — the audit must justify it
- 1,600 W under load: power, heat and placement need planning
- Anything spilling past the 252 GB HBM tier runs at LPDDR speed (396 GB/s)
- Arm platform — x86 containers need rebuilding

Understanding NVIDIA DGX Station
GB300 Grace Blackwell Ultra Desktop Superchip
The DGX Station is a data-centre superchip in a tower: NVIDIA's GB300 pairs a Blackwell Ultra GPU (252 GB HBM3e at 7.1 TB/s) with a 72-core Grace CPU (496 GB LPDDR5X at 396 GB/s) — 748 GB of coherent memory connected by 900 GB/s NVLink-C2C. That is enough to serve near-trillion-parameter open weights at FP4 — Kimi K2.6's native INT4 checkpoint is 594 GB — from one 1,600 W wall socket. MIG partitioning splits it into up to 7 isolated instances for a team.
Like the Spark, it is a reference platform: ASUS, Dell, HP, MSI, Gigabyte and Supermicro each build their own version, with integrator builds from Exxact — same silicon, different cooling, storage and support. (BOXX and Lambda were named at launch but have no shipping SKU as of July 2026.) Published pricing runs $85,000 (MSI's MSRP) to ~$126,000; several OEMs are quote-only, and the one verified UK sticker is ASUS's £117,599.99 inc VAT. Lead times run 4–12 weeks.
Worth knowing: the shipping silicon has 252 GB of HBM3e (7 of 8 stacks enabled) and 748 GB total — less than the 288 GB/784 GB originally announced and still widely misquoted. Stations cluster over dual 400 Gb ConnectX-8 Ethernet rather than NVLink, and a Windows edition ('DGX Station for Windows') arrives Q4 2026.
