The market for Micro ATX PSU (primarily referring to SFX and SFX-L form factors) is currently undergoing a significant shift toward high-wattage, high-density units driven by the power demands of next-gen GPUs (RTX 50-series) and the rise of "back-connect" motherboard ecosystems Alibaba. As of 2026, the SFX standard has moved from niche to mainstream, with 850W–1000W units becoming the baseline for enthusiast builds Directmacro Corsair.

Core Market Trends for 2026

* Form Factor Polarization: While traditional ATX remains the desktop standard, the Micro ATX (mATX) case market is increasingly adopting SFX-L to balance space and noise. SFX-L allows for larger 120mm fans, solving the high-load acoustic issues common in smaller 92mm-fan SFX units Directmacro.

* Technological Shift: The adoption of ATX 3.1 and GaN (Gallium Nitride) components is critical, enabling 1000W+ capacities in ultra-compact 100mm SFX footprints Newegg Alibaba.

* Aesthetic Integration: The rise of "Aquarium-style" cases and back-connect motherboards (e.g., ASUS BTF) has prioritized cable management flexibility over raw size. Innovation like side-mounted connectors is now a major selling point Alibaba Corsair.
