Which is the best PUE value for a data center?

Suggested Answer: A Vote an answer

Power Usage Effectiveness (PUE) measures data center efficiency, with an ideal value of 1.0 (all power used by IT equipment). A PUE of 1.2, indicating only 20% overhead, is highly efficient and closer to the ideal than
2.0 (100% overhead), 3.5, or 5.0, making it the best among the options for energy-conscious AI deployments.
