The market for ATX mini power supplies (primarily SFX and SFX-L form factors) is currently undergoing a critical technical transition driven by high-performance GPU demands and the rise of Small Form Factor (SFF) builds.

Core Market & Product Trends (2024–2026)

* The GaN Revolution: Gallium Nitride (GaN) technology has moved from premium to mainstream, enabling manufacturers to pack 850W–1000W+ into a standard SFX footprint while reducing heat output—a vital factor for space-constrained Mini-ITX cases Alibaba.

* ATX 3.1 Mandate: Consumer preference has shifted decisively toward ATX 3.1 compliance. This standard, alongside the 12V-2x6 connector, is now considered "future-proof" as it safely handles massive transient power spikes (up to 200% of rated capacity) without the connector melting risks associated with earlier ATX 3.0 designs AlibabaNewegg.

* Acoustic Optimization: There is a growing trend toward SFX-L for high-power builds (1000W+) because the extra 25–30mm of depth allows for a 120mm fan, resulting in significantly quieter operation compared to the 80mm/92mm fans in standard SFX units AlibabaDirectmacro.

* Cable Innovation: High-end builders now prioritize "micro-fit" (Type 5) modular cables and native 12V-2x6 support, avoiding bulky 8-pin adapters that obstruct airflow in sandwich-layout cases CorsairAlibaba.

Market Dynamics

The global DIY power supply market is projected to reach approximately $1.59 billion, with a steady growth rate fueled by the "Mini-PC" and enthusiast AI workstation niches WiseguyreportsKnowledge-Sourcing. Search interest for SFX units peaked in early 2026, corresponding with next-gen GPU releases .
