Another major development is the transition toward modular and compact form factors like SFX and SFX-L. These smaller units support the growing popularity of compact desktops and mini-PCs in both residential and commercial settings. Coupled with advancements in APFC (Active Power Factor Correction) and DC-to-DC conversion, manufacturers are delivering smaller-sized PSUs that maintain high performance, even under thermal constraints.
Digital monitoring capabilities are also on the rise, with PSUs now featuring onboard microcontrollers for real-time voltage and current tracking, fan control, and firmware upgrades. This enables predictive maintenance and seamless integration with software dashboards in gaming and enterprise ecosystems, aligning with the broader digitalization and Industry 4.0 movement.
Finally, the proliferation of high-power designs (e.g. up to 1600 W) is notable in response to dual-GPU and AI development systems. While mass-market desktop PSUs typically stay within the 500–1000 W range, the high-performance computing (HPC) and server segments show growing appetite for specialist units.
