Summary of Conference Call Records Industry Overview - The AI power supply equipment industry is experiencing significant technological changes, particularly in GPU power consumption, which has increased from 200W to 300W and may double in the future. The number of cards in cabinets is also rising, from 172 to potentially 288 cards, leading to increased cabinet power from 198kW to an expected 500kW or even megawatt levels by 2027-2028. This presents challenges for data center space architecture but also opportunities for leading domestic companies [2][6][10]. Key Points and Arguments - **Market Size and Pricing**: The price of power supplies is approximately 2 yuan per watt. A 200kW cabinet corresponds to a market space of about 40 billion yuan, with the overall market potentially reaching 100 billion yuan when including components like supercapacitors and BBO [4][5]. - **HVDC Technology**: As cabinet power exceeds 250kW, the need for higher energy efficiency will drive the adoption of HVDC paths, with penetration expected to rise from 10% to over 20% by 2026. Major overseas clients are choosing Delta and Veichi Technology, while domestic companies like Megmeet, Kehua, and Kstar are also actively positioning themselves [6][10]. - **Supercapacitors**: Supercapacitors are crucial in AI power supply devices, capable of handling millisecond-level fluctuations. For instance, the JD300 chip can experience a 90% fluctuation, equating to a 1.9kW variation for a 1kW load. Supercapacitors provide high-frequency, long-lifetime energy storage solutions, essential for system stability [7][9]. - **Investment Opportunities**: There are multiple investment opportunities in PSU, HVDC, and DC-DC segments. Companies like Megmeet and HVDC-related firms show strong certainty, while new players like Newray may achieve AC-DC conversion. Jianghai Co., Blok New Materials, and Sanhuan Group may also see new opportunities due to technological changes [12]. Additional Important Insights - **Technological Iteration**: The secondary power supply (ACDC) segment is expected to undergo technological iterations due to increased power density. The core components will change as integration levels rise and switching frequencies increase from 30kHz to 500kHz, presenting substantial investment opportunities [3]. - **Market Potential for Jianghai Co.**: Jianghai Co. has secured significant orders from major clients like Meta for supercapacitors, with each module priced around $5,000. The company is expected to capture a significant market share and gradually realize profits as downstream clients ramp up demand [10]. - **Impact of IFAX**: The anticipated increase in IFAX production in 2026 will lead to changes in the DC-DC segment, with a projected market space of 1.7 billion yuan for chip-level components. Companies like Boke, with integrated advantages, are expected to capture a large share of this market [11].
