NVIDIA DGX B300,
supplied per project
NVIDIA’s 10U system with eight Blackwell Ultra GPUs and 2.1 TB of HBM3e. We supply it per project, and HGX B300 servers the same way, on one EU contract and invoice. Before we can quote, the distribution asks us for the company, the project and the intended use, and approvals take longer than an order for cards.

DGX B300 specifications
Figures from NVIDIA’s DGX B300 product page (updated 15 October 2026), its datasheet (February 2026) and its user guide (updated 5 October 2026). We do not publish prices: the configuration, the support level, the licences and the approval of the project decide the quote.
| Specification | DGX B300 | What it means for your project |
|---|---|---|
| GPUs | 8 × Blackwell Ultra SXM, 288 GB HBM3e each | NVIDIA lists 2.1 TB per system; plan with about 270 GB per GPU |
| GPU memory | 2.1 TB HBM3e, 62 TB/s | A 70B model in FP8, about 73 GB of weights, fits one GPU with close to 200 GB left for KV cache |
| NVLink | 2 × NVLink Switch System, 14.4 TB/s aggregate | A model split across all eight GPUs stays inside one NVLink domain |
| FP4 Tensor Core | 144 PFLOPS sparse, 108 PFLOPS dense | NVIDIA prints most Tensor Core figures with sparsity, so compare dense with dense across systems |
| CPUs, memory | 2 × Intel Xeon 6776P, 2 TB, up to 4 TB | Set by NVIDIA; in HGX B300 servers the manufacturer defines CPU and memory |
| Networking | 8 × ConnectX-8 at up to 800 Gb/s; 2 × BlueField-3 at up to 400 Gb/s | The system ships without network cables or adapters, so switch ports, transceivers and fibre belong in the quote |
| System power | 15.1 kW (power supplies), 14.5 kW (busbar) | datasheet rating; NVIDIA’s data-centre guide estimates peaks above it, 19.7 kW and 19 kW, so size feeds and cooling to the peak |
| Size, weight | 10U, 442 × 482.6 × 904.2 mm; 168 kg (power supplies), 123 kg (busbar) | Check the rack depth, the floor rating and the route from the loading bay |
| Software, support | DGX OS 7 included; NVIDIA AI Enterprise recommended; three years of business-standard support | AI Enterprise is licensed per GPU: eight licences per system where it is used |
Supplied per project: we check price and availability for your project once the distribution has the company, the project and the intended use.
How a DGX B300 project order works
The approval comes before the quote, for one system or for two. Approvals take longer than an order for cards.
The quote lines, the export rules and the delivery are covered in our guide to buying a DGX B300 in the EU.
What we need from you
Legal entity, registered address and VAT number. The distribution asks for it before a quote.
Purpose, number of systems and project owner. The distribution asks for it before a quote.
Training, fine-tuning or inference, the models and data, the sector. The distribution asks for it before a quote.
Own data centre or colocation, country and rack position. The site decides the AC or busbar version, the power distribution and the delivery.
If the organisation that operates the system is not the buyer, or the system will leave the EU, name the end user and the destination as well: an export end-use statement covers both. Our guide to the end-user certificate for NVIDIA GPUs explains what such a statement contains and who signs it. Whether a delivery needs an export authorisation is a legal assessment for your company’s legal department.
Before you order: the room
We check the rack, power and airflow before we quote. These are NVIDIA’s figures to hold against your room or your colocation contract.
The AC version has twelve 3.2 kW power supplies in N+N redundancy at 200 to 240 V and twelve C19/C20 inlets, so one system takes twelve C19 outlets. NVIDIA’s data-centre guide estimates a peak of 19.7 kW per AC system and plans two systems per rack at 39.4 kW peak. The busbar version takes 54 V DC from power shelves that are not included with the system.
Power and cooling for a GPU rack →The system weighs 168 kg with power supplies and 123 kg in the busbar version, takes 10U and is 904.2 mm deep. Packed, the AC system weighs 207.6 kg in a crate of 1,065 × 711 × 1,178 mm, so check the loading dock, the doors, the lifts and the floor rating on the way to the rack.
DGX B300 specs and site checklist →The user guide gives an inlet air range of 10 to 30 °C, and NVIDIA’s data-centre guide lowers the maximum above 1,000 ft (about 300 m). The guide asks for up to about 2,145 CFM of supply air per system at sea level and recommends active rear-door heat exchangers for dense racks; passive ones are not recommended for the DGX B300.
Liquid cooling for GPU racks →DGX B300 or a PCIe server
A DGX B300 keeps eight GPUs and 2.1 TB of HBM3e in one NVLink domain, and as of October 2026 we found no NVIDIA B300 PCIe card. Where each model copy fits one 96 GB or 141 GB card, a PCIe server is the other route: we build AI servers to order with 2 to 8 H200 NVL or RTX PRO 6000 Server Edition cards, assembled and burn-in tested, with configuration and quote within one business day. Our comparisons DGX B300 or a server with eight RTX PRO 6000 and RTX PRO 6000 vs H200 NVL for LLM inference set them side by side.
HGX B300 servers and the DGX Station
Server manufacturers build HGX B300 servers around NVIDIA’s eight-GPU baseboard, with their own processors, memory, cooling and support. We supply them per project, the same way as the DGX B300.
DGX B300 vs DGX B200 vs HGX B300 →We supply manufacturers’ versions of the DGX Station GB300 per project as well.
