Supermicro Expands NVIDIA Blackwell Portfolio with New 4U and 2-OU (OCP) Liquid-Cooled NVIDIA HGX B300 Solutions Ready for High-Volume Shipment

On Dec. 9, 2025, Super Micro Computer, Inc. announced shipment availability of new 4U and 2-OU liquid-cooled NVIDIA HGX B300 systems, expanding its Blackwell portfolio.
Responding to accelerating AI demand, Supermicro built liquid-cooled NVIDIA HGX B300 systems to meet hyperscalers' and AI factories' needs for improved TCO, serviceability and deployment speed via Supermicro Data Center Building Block Solutions .
Designed for rack-scale density, the systems provide a 4U Front I/O liquid-cooled design capturing up to 98% of heat with DLC-2, running eight NVIDIA Blackwell Ultra GPUs and 2.1TB HBM3e memory.
For heavy AI workloads, Supermicro says data centers can achieve up to 40 percent power savings with the DLC-2 technology stack and 45°C warm water operation, accelerating foundation model training, agentic AI, and multimodal inference.
At cluster scale, Supermicro shows a SuperCluster unit with 1,152 GPUs, combining eight HGX B300 racks, three NVIDIA Quantum-X800 InfiniBand racks, and two in-row CDUs, with network throughput up to 800Gb/s via NVIDIA ConnectX-8 SuperNICs.
