Infineon strengthens its leadership position with new PSUs based on Si, SiC and GaN
Industry-first 12kW PSU achieves high energy efficiency, power density, and reliability

Infineon Technologies AG (Infineon) is helping cloud data center and AI server operators reduce energy consumption required to cool their systems by delivering unprecedented PSU performance.

Infineon today announced a roadmap for power supply units (PSUs) specifically designed to meet the current and future energy demands of AI data centers.

As AI drives increased energy demand for data centers around the world, efficient and stable energy supply for servers has become increasingly important.

The PSU reduces power consumption and CO2 emissions, thereby reducing operating costs over its lifetime.

Not only is this PSU suitable for the data centers of the future, it can also replace existing power supplies in servers to improve efficiency.

In addition to the already released 3kW and 3.3kW PSUs, the new 8kW and 12kW PSUs will help further improve the energy efficiency of AI data centers.

Infineon is responding to the needs of data center operators to increase system efficiency and minimize downtime.

The growth of server and data center applicationsThe increased power demand has necessitated the development of power supplies with higher power ratings, from 800 W up to 5.5 kW or more.

This is due to the increased power requirements of GPUs running AI applications.

Current high-level GPUs require up to 1kW per chip, and are expected to reach 2kW or more by the late 2020s.

This will lead to an increase in the overall energy demand of data centers.

The International Energy Agency (IEA) predicts that data centers will account for 7% of global electricity consumption by 2030, a figure similar to India's current electricity consumption.

Infineon's new PSUs could help limit the CO2 footprint of AI data centers despite rapidly increasing energy demands.

This requires minimizing power loss with very high efficiency.

Infineon's next-generation PSU achieves 97.5 percent efficiency and meets stringent performance requirements.

The new 8kW PSU can support AI racks with up to 300kW of power output.

Efficiency and power density are improved to 100W/in³ compared to 32W/in³ of conventional 3kW PSUs, providing further benefits in reducing system size and operating costs.

From a technical standpoint, this is possible through a unique combination of three semiconductor materials: Si, SiC and GaN.

These technologies contribute to the sustainability and reliability of AI servers and data center systems.

Innovative semiconductors based on wide bandgap materials such as SiC and GaN offer efficient energyIt plays a very important role in the dragon.

Supply of the 8kW PSU is expected to begin in the first quarter of 2025.
