Transforming data center sustainability: power electronics leads the way
How do power electronics innovations impact the PSU industry?
- In 2022, the total PSU market for data centers was worth US$7.4 billion, and it is expected to increase at 6% CAGR22-28 , reaching US$10.5 billion by 2028.
- The total market for power devices for PSUs is projected to grow to US$392 million in 2028, with a 7.8% CAGR22-28.
- The output voltage of the PSU will increase from 12 V to 48 V to achieve higher power without deterioration of efficiency. Therefore, the market segment for 100 V devices will increase in the forecast period (5.9%).
- Wide bandgap devices are expected to be increasingly adopted: the market value of SiC and GaN devices will feature a double-digit CAGR between 2022 and 2028.
- Eight-inch silicon wafers are mainly used for Si MOSFETs for data center PSUs.
The overall power device market for PSUs is presenting a significant 7.8% CAGR between 2022 and 2028. This growth is driven by the trend towards PSUs featuring a 48 V output voltage, as opposed to the traditional 12 V.
Yole Intelligence, part of Yole Group, estimates this market will grow from US$250 million in 2022 to US$392 million by 2028.

Milan Rosina, Ph.D., Principal Analyst for the power electronics and battery division“To address the increasing power needs of new AI servers, it is expected that PSUs with a capacity exceeding 3 kW will experience the highest CAGR at 17.6%. This growth will translate into an increase from US$1.5 billion in 2022 to US$3.9 billion by 2028.”
Consequently, there is notable growth in the PSU market, which is crucial for regulating server voltage. Projections indicate that the PSU market is anticipated to reach US$10.5 billion by 2028, with a CAGR2022-2028 of 6%.

Enhancing the PUE within data centers holds great significance in the quest to reduce operational expenses, minimize energy consumption, and align with environmental sustainability objectives. Constant technological advancements are occurring at both the PSU level and within the associated infrastructure.
PSU manufacturers are not only aiming to augment power capacity by moving from 3 kW to 6 kW but also to enhance power density, transitioning from 45 W/in³ to 100 W/in³. This can be achieved by utilizing WBG materials alongside an increase in the output voltage level from 12 V to 48 V.
Conversely, hyperscale data center and HPC facilities are receptive to implementing infrastructure changes that contribute to an improved PUE. For instance, BBUs have the potential to replace upstream UPS at the rack level, and existing servers and racks can be retrofitted for liquid cooling in place of conventional air-cooling methods. The adoption of DC power distribution offers energy-efficient advantages, representing a viable mid-term strategy once DC standards and associated equipment reach a higher level of maturity.
