The new power supply units boost energy efficiency in AI data centres, effectively reducing costs and CO₂ emissions.


The rise of artificial intelligence (AI) is increasing the energy consumption of data centres worldwide. This surge in demand highlights the necessity for efficient and dependable server energy sources. Infineon Technologies AG is stepping into a new era of energy solutions for AI systems by launching a strategic plan for power supply units (PSUs) tailored to meet the energy requirements of AI data centres, focusing on efficiency.

The company has introduced PSU performance categories that allows operators of cloud data centres and AI servers to reduce energy used for system cooling. These PSUs lower power usage and CO₂ emissions and reduce total operating costs over their lifespan. These units are set to be used in future data centres and can also upgrade existing server PSUs to enhance efficiency.

Alongside the already available 3 kW and 3.3 kW PSUs, Infineon will soon introduce new 8 kW and 12 kW models, boosting energy efficiency in AI data centres. The upcoming 12 kW reference board will mark the introduction of the world’s first PSU capable of this performance level, powering the data centres of tomorrow.

The PSUs are aiding efforts to reduce the CO₂ footprint of AI data centres despite their rapidly growing energy demands. This reduction is achieved through high-efficiency levels that minimize power losses. Infineon’s latest PSUs boast an efficiency of 97.5 per cent and meet the most stringent performance criteria. The new 8 kW PSU can support AI racks with a total output of up to 300 kW and more. Furthermore, these units increase efficiency and power density to 100 watts per cubic inch, a significant improvement over the 32 W/in³ offered by the currently available 3 kW PSU, providing additional system size reductions and cost savings for operators.

“At Infineon, we power AI. We are addressing a critical question of our era – how to meet the escalating energy demands of data centres efficiently,” says Adam White, Division President of Power & Sensor Systems at Infineon.
