Power Integrations says collaborating with Nvidia on transition to 800 VDC power

Power Integrations (POWI) outlined the benefits of its PowiGaN gallium-nitride technology for 800 VDC power architectures in a new white paper, published at the 2025 OCP Global Summit in San Jose, where Nvidia (NVDA) provided an update on the 800 VDC architecture. Power Integrations is collaborating with Nvidia to accelerate the transition to 800 VDC power and megawatt-scale racks, the company stated. “With rising AI power demands, moving to an 800 VDC input simplifies rack design, makes more efficient use of space and reduces copper usage. With rising rack power demands, we see 1250 V and 1700 V PowiGaN devices as ideal choices for main and auxiliary power supplies, delivering the efficiency, reliability and power density required in 800 VDC data centers,” said Roland Saint-Pierre, vice president of product development at Power Integrations.
