Core Insights - The article discusses the increasing importance of high-voltage direct current (HVDC) technology in data centers, particularly in the context of NVIDIA's 800V HVDC architecture, which aims to address power efficiency and component space issues in AI server designs [9][11]. Group 1: NVIDIA's HVDC Technology - NVIDIA's 800V HVDC architecture is designed to improve energy efficiency by reducing the number of AC/DC conversion steps, potentially increasing end-to-end power efficiency by up to 5% [11]. - The architecture aims to lower maintenance costs by 70% due to reduced PSU failures and lower labor costs for component maintenance [11]. - The expected power capacity of NVIDIA's Rubin Ultra NV576 cabinet is projected to exceed 600kW by 2027, significantly higher than traditional server cabinets [9]. Group 2: Market Potential and Growth - Bernstein estimates that the total addressable market (TAM) for NVIDIA's AI server power components will exceed $8 billion by 2027, doubling from $4 billion in 2025 [4]. - The power component share in NVIDIA's VR200 series is expected to be 2-3 times that of the GB200 NV72 series, driven by increased GPU thermal design power (TDP) [3]. - The VR Ultra series, utilizing the 800V HVDC technology, is anticipated to have a power component share 7-8 times that of the GB200 series, reflecting the growing demand for high-density GPU configurations [3]. Group 3: Delta's HVDC Solutions - Delta's 800V HVDC solution aligns with NVIDIA's approach, focusing on a single-step conversion from medium-voltage AC to high-voltage DC, which replaces traditional multi-stage conversion processes [13]. - Delta plans to implement its HVDC solutions in three phases, starting with a transitional 50V server solution and progressing to native 800V servers [15][16]. - The final phase aims to utilize solid-state transformers (SST) for AC-DC conversion, enhancing efficiency to over 92% and significantly reducing operational costs [16]. Group 4: Competitive Landscape - Key players in the HVDC market include Delta, Lite On/Flex Power, and others, with Delta aiming to double its AI power component revenue by 2025 compared to competitors [20]. - Companies like LITE-ON and Flex Power are also focusing on AI server power solutions, with specific revenue targets and product developments in the HVDC space [20][21]. - The competitive landscape is characterized by ongoing collaborations and technological advancements aimed at enhancing power efficiency and reducing costs in data center operations [20][21].
