## AI 摘要

NVIDIA 800V DC 供电计划采用分阶段部署，与现有 AC 配电系统并行，按设施情况逐步推进而非整体替换。短期 Power Rack 将 800V DC 送入计算机架并标准化 DC 接口；中期行级 Power Center 通过母线槽集中整流供电；长期机厅级 DC Power Block 将成为标准供电模块。NVIDIA 将与行业伙伴合作扩大示范和试点。

NVIDIA’s 800 VDC plan includes a phased rollout that operates alongside existing AC distribution systems. The adoption level depends on each facility individually, rather than replacing an entire plant all at once.

In the short term, NVIDIA’s Power Rack delivers 800V DC into the compute racks and standardizes the DC interface and backup configuration so it can fit existing AC infrastructure. Following this, a row-level Power Center manages centralized rectification and supplies a full high-density row via a busway, reducing cabling complexity in white space. Over the longer term, a hall-level DC Power Block becomes the standard power building block, supporting higher-density loads.

NVIDIA will collaborate with industry partners to expand demonstration and pilot sites ahead of large-scale deployment.
