The conversation dives deep into the dramatic rise in GPU and server rack power consumption, from under 1 kilowatt per GPU just a few years ago to projections exceeding 600 kilowatts per rack in the near future, and what that means for data center architecture. Diogo walks through the generational shift in rack design, as well as novel energy buffer concepts, advanced PFC topologies, and the strategic use of WBG technologies to maximize efficiency and help hyperscalers drive down their Power Usage Effectiveness (PUE).","meta_description":"In this episode of Podcast4Engineers' \"We Power AI\" series, host Kelsey Markl sits down with Dr. Diogo Varajao, Head of Power Supply and Battery Backup Sy…","key_points":[],"chapters":[],"topics":[],"duration_seconds":1374,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/podcast4engineers-7195700/episodes/the-server-rack-evolution-toward-3-phase-psus/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/podcast4engineers-7195700/the-server-rack-evolution-toward-3-phase-psus.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
