Taking an Up-Close Look at the Supermicro GB300 Super AI Station

Supermicro showcased its Super AI Station, a DGX Station system powered by NVIDIA's GB300 Grace Blackwell chip, at Computex 2026. The liquid-cooled desktop features 252GB of GPU memory, 496GB of CPU memory, and 400GbE networking, with a 1600W TDP and optional rackmount capability. Priced around $125,000, it is one of the most expensive desktop computers available.

With NVIDIA announcing multiple new desktop system designs at Computex 2026, NVIDIA’s partners were understandably eager to show off their current and forthcoming wares. For most desktop users, the highlight of the show is arguably running into an NVIDIA DGX Station system, which at around $125,000 each via Newegg Affiliate link https://fave.co/4w2z9FQ is in the running as the most expensive desktop computer available, and the only way to get NVIDIA’s flagship GB300 accelerator in something smaller than a server. As luck would have it, we happened to run into one of those systems over at the Supermicro Computex 2026 booth, where NVIDIA’s partner had its DGX Station system, the Super AI Station, on full display. Supermicro Super AI Station The Super AI Station is Supermicro’s DGX Station offering. And kudos to the company for understanding just how interesting a product they had on their hands. While they did not have the system open, they did the next best thing by putting a plexiglass panel on its side so that attendees could get a good look inside. As with GB10 systems, NVIDIA has kept OEMs on a relatively short leash with DGX Station systems. NVIDIA provides the critical motherboard and processors, leaving OEMs to design a system around it while meeting NVIDIA’s specifications for things such as port availability and power. The end result is that the core components and layout of a DGX Station system are all going to look very similar to Supermicro’s system. At its heart is the Grace Blackwell GB300 chip, which combines a 72-core Grace CPU die with a Blackwell GPU. With most of the system’s 1600 Watt TDP going to that chip, Supermicro has opted for liquid cooling here, covering all critical components with cold plates and running a radiator loop to carry away the heat. This includes the four LPDDR5X SOCAMMs that provide the 496GB of memory for the Grace CPU, so while those are technically removable, they are not easily accessible. As for the Blackwell GPU, NVIDIA is using a de-rated part here. DGX Station systems ship with only 7 of the 8 HBM3e stacks on the chip enabled, for a total of 252GB of GPU memory and a total memory bandwidth of 7.1TB/second. As for storage options, all DGX Station systems come with four PCIe Gen5 x4 M.2 2280 slots, which, for its showcase system, Supermicro filled with 480GB Micron 7450 Gen4 x4 drives. Meanwhile, they also had an NVIDIA RTX PRO video card installed, an optional upgrade that NVIDIA allows. Despite shipping with the Blackwell Ultra GPU, you need another GPU for a workstation if you want something better than BMC video output. The GB300 is not graphics-capable due to its compute-optimized design, so an RTX PRO card must be installed to enable graphics beyond BMC video. This leaves two more PCIe x16 x8 electrical slots available for further upgrades. From the side angle, you can also just make out the system’s 400GbE QSFP ports, which are covered with a small heatsink. Along with the GB300 system itself, NVIDIA’s ConnectX-8-powered Ethernet is the other marquee feature of the DGX Station system, with the two 400Gb ports providing ample bandwidth for networking multiple systems together or for a fast backhaul between the Station and other machines on the local network. With the GB300 and motherboard at the rear of the system, Supermicro has placed the system’s sizable radiator towards the front. Three fans pull air through that radiator, push it through the rest of the system, and eventually out the rear. This front-to-back configuration is an intentional choice on multiple levels. Besides being the customary setup for a high-end workstation, this ensures that the Super AI Station is suitable in a rackmount setup. The desktop computer can, if desired, be outfitted with a rackmount kit, allowing it to be mounted as a 5U server. This is not going to be a space-efficient option versus a traditional HGX-based server, but it is an easy way to get a single GB300 installed in a rack. It is also a differentiator for Supermicro that may make a lot of sense to people. Not everyone will want a 1.6kW system running at their desk. If you ever do find yourself looking at the front of a Super AI Station, this is what you will be looking at. The front of the all-black system is primarily for ventilation, given its significant TDP. Otherwise, up towards the front-right corner, you will find the system’s two front-accessible 5Gbps USB 3 ports. There are four 10Gbps USB 3 ports on the rear, but no USB-C ports to speak of on the system. Final Words NVIDIA’s DGX Stations are a hot item and in more ways than one. For anyone looking to do local development and testing against a GB300 system while wanting said system on their desktop, the DGX Station is the way to do it. Just make sure you have a dedicated power circuit available, as the GB300 used in Supermicro’s Super AI Station still draws 1600 Watts at full load. For better or worse, there is nothing quite like them. Along with the current DGX Station systems that come pre-loaded with NVIDIA’s custom Ubuntu distro, DGX OS, we will also see the systems later this year when OEMs begin selling Windows versions under the DGX Station for Windows https://www.servethehome.com/nvidia-computex-2026-news-bytes-vera-rubin-now-in-production-dgx-station-gets-windows/ branding.
