For developers who need server-grade AI compute without the data center footprint, Gigabyte’s W775-V10-L01 is a serious contender. Based on the NVIDIA DGX Station GB300 architecture, this system squeezes a full Grace CPU and Blackwell Ultra GPU stack into a liquid-cooled tower that weighs 29kg. While it fits under most desks, the 1.6kW maximum power draw means you are effectively running a dedicated circuit on your floor.

Hardware And Performance Specs

The core of the W775 is the NVIDIA Grace 72-core Neoverse V2 CPU paired with a Blackwell Ultra GPU, backed by 496GB of LPDDR5X memory and 252GB of HBM3E. ServeTheHome’s testing revealed exceptional throughput, with the Qwen3.6-35B-A3B Flash NVFP4 model running at over 26,000 tokens per second. This translates to more than 2.25 billion tokens processed per day, making it a viable local engine for heavy inference tasks.

Cooling And Physical Constraints

Do not expect this to be a silent office companion. The system relies on an extensive liquid cooling setup with a 1600W 80 PLUS Platinum power supply. Gigabyte advises a two-person lift due to the weight, and the chassis design prioritizes airflow on the sides and bottom rather than the front. This means the front panel is purely decorative, with all I/O ports relocated to the top and rear to accommodate the cooling requirements.

Networking And Connectivity

Connectivity is dominated by NVIDIA’s ConnectX-8 SuperNIC, which provides dual 400Gbps QSFP112 ports for high-speed RDMA networking. Interestingly, the 10GbE RJ45 port is also routed through the ConnectX-8 rather than the CPU directly. For storage, the system features two PCIe Gen6 M.2 slots and two PCIe Gen5 slots, ensuring that local data throughput does not become a bottleneck for the GPU.

Key Takeaways

  • The system requires a dedicated 20-amp circuit due to its 1.6kW power draw.
  • Liquid cooling is mandatory, adding significant weight (29kg) and complexity.
  • Dual 400Gbps QSFP112 ports allow for cluster scaling via RDMA.
  • Performance on Qwen3.6 models exceeds 26,000 tokens/second.

The Bottom Line

This is not a toy; it is a professional tool that demands professional infrastructure. If you have the circuit breaker capacity and the desk space, the W775-V10-L01 offers unrestrained Grace Blackwell performance without the rack-mount hassle.
