NVIDIA HGX B200
HGX B200 is the 8-GPU Blackwell baseboard NVIDIA sells to OEMs, not a server you can rack yourself. Supermicro, Dell, Lenovo, HPE, ASUS and ASRock Rack each bolt their own CPUs, chassis, power delivery, storage and networking around the same baseboard and NVSwitch fabric, then sell the result as a complete server. Most private HGX builds go through one of those OEM boxes rather than NVIDIA's own DGX B200, because the OEM path lets a buyer choose CPU vendor, memory footprint, NIC mix and air vs liquid cooling to fit an existing rack and budget, while DGX B200 ships as a fixed configuration at a materially higher price for the same GPU count.
- HGX is a baseboard, not a server. The OEM decides chassis, power delivery, cooling method and network configuration; NVIDIA only fixes the GPU-to-GPU fabric. Two 'HGX B200' servers from different vendors can differ meaningfully in CPU, storage and total power draw.
- Air-cooled B200s cap at 1,000 W per GPU; liquid-cooled bins run to 1,200 W. If a build spec assumes the higher TDP figure, verify the OEM SKU actually ships with direct-to-chip liquid, not just air with a liquid-ready chassis.
- Budget rack power and cooling as a separate line item, not a rounding error. A single 8-GPU HGX B200 server can pull 10 to 15 kW, meaning a handful of nodes will exceed the power density of a legacy air-cooled rack.
- DGX B200 and HGX-OEM servers share the identical GPU baseboard and NVLink/NVSwitch fabric. The price gap between them buys NVIDIA's fixed configuration, software stack and direct support, not more silicon. Teams comfortable managing their own OS and driver stack save real money going OEM.
- Lead time, not price, is usually the binding constraint in 2026. Confirm actual allocation with the OEM's sales team before quoting a delivery date to a client; published 'ships in 4 to 6 weeks' figures generally assume an existing NVIDIA Partner Network relationship.
How much does an HGX B200 server cost?
Reported street pricing for a fully configured 8-GPU HGX B200 server runs roughly $300,000 to $500,000 or more, depending on CPU, memory, storage, networking and cooling choices. This excludes rack power and cooling infrastructure.
What is the difference between HGX B200 and DGX B200?
They use the same 8-GPU Blackwell baseboard and NVLink/NVSwitch fabric. HGX B200 is the baseboard NVIDIA sells to OEMs like Supermicro, Dell, Lenovo, HPE, ASUS and ASRock Rack, who each build their own server around it. DGX B200 is NVIDIA's own fixed-configuration server built on that same baseboard, priced higher and sold with NVIDIA support.
How much power does an HGX B200 8-GPU server draw?
The GPUs alone draw 8 kW air-cooled (1,000 W each) or 9.6 kW liquid-cooled (1,200 W each). A fully configured server with dual CPUs, memory, storage and networking is reported to draw roughly 10 to 15 kW.
What is the lead time to get an HGX B200 server?
Reported lead times run 8 to 16 weeks for standard configurations through an OEM with an existing NVIDIA allocation, and beyond 20 weeks for custom BOMs. Buyers without an established OEM relationship should expect longer waits given ongoing HBM3e supply constraints.
