Why Does a S$150,000 DGX Station Need Another Graphics Card?

Because the GB300 superchip at the heart of a DGX Station has no display output. Its Blackwell Ultra GPU is a compute engine. The only video port on the system is a Mini DisplayPort for the BMC management controller, which NVIDIA says "is intended only for system management". To run monitors, a desktop session or graphics applications, you add a professional RTX PRO card in one of the PCIe slots. HP ships its ZGX Fury G1n with an RTX PRO 2000 or RTX PRO 4000 SFF already fitted. The MSI, ASUS, GIGABYTE and Supermicro systems quote the card separately. The catch is power. Every DGX Station shares one 1,600W budget, and a large card takes some of it away from the GB300.

What does the extra graphics card actually do?

• Drives your monitors. Without it, the system runs headless: users connect over SSH, a web interface or remote desktop, and IT uses the BMC console for setup and recovery.
• Handles graphics APIs. Visualisation, CAD viewers, 3D tools and anything using OpenGL or Vulkan need a graphics-capable GPU. NVIDIA's MIG documentation also notes that graphics APIs are not supported inside MIG instances, so sharing the GB300 between users does not help with graphics work.
• Keeps interactive work off the main GPU. A desktop session, video playback and screen sharing run on the RTX card, leaving the GB300 for training and inference.
• Adds a second, smaller CUDA GPU. A card like the RTX PRO 4000 SFF (24GB) can run small models or tests while the GB300 is busy, though it is no substitute for the GB300's 252GB of HBM3e.

NVIDIA's DGX Station documentation lists the RTX PRO 6000 Blackwell Workstation Edition, RTX PRO 6000 Max-Q, RTX PRO 4000 SFF and RTX PRO 2000 as supported cards, with the note that "support may vary by system". Check the specific OEM before ordering a card separately.

How much GB300 performance does each card cost you?

This is the part most buyers miss. NVIDIA's documentation on "dynamic power sloshing" explains that the 1,600W system budget is shared, with the RTX card given priority. The GB300's power cap depends on how much the card can draw:

Power caps from NVIDIA's DGX Station Development Guide, "Dynamic Power Sloshing" (accessed 4 Nov 2026). Card power from NVIDIA's RTX PRO Blackwell specifications (RTX PRO 2000 and 4000 SFF via CG Channel, Aug 2025). Prices are SourceIT listings on 4 Nov 2026. We have not tested these configurations ourselves.

A 600W RTX PRO 6000 Workstation Edition lowers the GB300's cap from 1,600W to 950W, a cut of 650W. Even the 300W Max-Q version costs 350W of headroom. ServeTheHome, in its MSI XpertStation WS300 review (23 Oct 2026), advises against fitting an RTX PRO 6000 unless you genuinely need it. The two 70W cards that HP fits fall under the 75W threshold, so they leave the GB300's full budget intact.

For most DGX Station buyers, the right display card is the smallest one that does the job. Every watt the card can draw is a watt the GB300 may not get.

Which OEMs include a card?

• HP ZGX Fury G1n. Factory configurations with an RTX PRO 2000 Blackwell 16GB (with 4×2TB storage) or an RTX PRO 4000 Blackwell SFF 24GB (with 2×2TB plus 2×4TB). There is also a headless version with self-encrypting drives and no card, for server-room deployments.
• Supermicro ARS-511GD-NB-LCC. RTX PRO 2000, 4000 SFF, 6000 Max-Q or 6000 Workstation Edition, quoted separately. The listing allows one double-width GPU at most.
• MSI XpertStation WS300, ASUS ExpertCenter Pro ET900N G3, GIGABYTE W775-V10-L01. An RTX PRO Blackwell display card is optional and quoted separately. ASUS's SKU family includes a configuration with an RTX PRO 2000.

All five share the same slot layout from NVIDIA's board: one PCIe 5.0 x16 slot and two x16-length slots wired at x8. Using a slot for a display card also leaves less room for other add-ins, such as an extra network or storage card.

Do you need a graphics card at all?

Ask how people will use the system.

• Shared team server. If the Station sits in a server room and a team reaches it remotely, headless is usually best. The GB300 keeps its full 1,600W budget, and IT manages it through the BMC. See NVIDIA DGX Station: The Most Expensive Computer Your Employees Might Never Touch.
• One power user at a desk. A researcher who wants monitors, a local desktop and Jupyter on screen needs a card. An RTX PRO 2000 or 4000 SFF is the efficient choice.
• Visualisation alongside AI. If the same person renders, simulates or reviews 3D data, a bigger card makes sense, but accept the GB300 power trade-off. For heavy engineering graphics, a separate workstation may be better. We discuss that in Could DGX Station Replace a Room Full of Traditional Engineering Workstations?

Frequently asked questions

Does the DGX Station GB300 have a display output? Not from the GB300. The only video port is a Mini DisplayPort for the BMC, which NVIDIA says is for system management only. Monitors need an RTX PRO add-in card.

Which graphics card should I add to a DGX Station? For most users, an RTX PRO 2000 or RTX PRO 4000 SFF. Both draw 70W, under NVIDIA's 75W threshold, so the GB300 keeps its full 1,600W power cap.

Does an RTX PRO 6000 slow the GB300 down? It can. With a card over 300W, such as the 600W RTX PRO 6000 Workstation Edition, NVIDIA caps the GB300 at 950W. A 300W Max-Q card caps it at 1,250W.

Can I run the DGX Station without any graphics card? Yes. Headless operation over SSH, a web interface or remote desktop is common for shared systems, and HP offers a headless ZGX Fury configuration.

Can MIG instances run graphics applications? No. NVIDIA's MIG documentation says graphics APIs are not supported inside MIG instances, so graphics work needs the RTX card or a separate workstation.
