The ever-increasing power demand driven by AI data centers is forcing an expedited evolution of power supply units (PSUs) designs, growing from 800 W to an astounding 12 kW, with projections heading to 3-phases designs. their power supplies than ever before. Moreover, the. Data centers evolve to meet AI's massive power needs Technical Article Data centers evolve to meet AI's massive power needs Brent McDonald, systems and applications engineer, Texas Instruments With large language models revolutionizing how we access data, artificial intelligence (AI) advancements. The rise of artificial intelligence (AI) has significantly increased computing demands, necessitating more powerful AI servers and robust, efficient power supplies. This surge in computational power correlates with higher power consumption, creating a need for greater power levels and higher watts. An AI server is a specially designed and optimized server that may have one or more high-performance GPUs (Graphics Processing Units) or dedicated AI accelerators, such as Google's Tensor Processing Units (TPU) or NVIDIA's AI accelerator cards, among others. Despite this, rack space and PSU form factors will remain unchanged, pressuring PSU vendors to achieve higher power density.
