No, the PSU above is not an SFX model.
“This design maximizes space for airflow within PC cases while delivering robust power in line with the ATX 3.1 specifications, including up to a 235% power excursion. Equipped with a 600W 12V-2×6 cable, the REVOLUTION D.F. 12 ensures uncompromised performance for high-end graphics cards and cutting-edge AI computing. The REVOLUTION D.F. 12 also fits seamlessly into micro ATX cases, providing ample room for efficient cable management.”
These REVOLUTION D.F. 12 power supplies feature 115 mm dual-ball bearing fans, with a self-cleaning function (“Enermax’s patented Dust-free Rotation (D.F.R.) technology”), that spins the fan in the opposite direction to help clear dust accumulation when you activate the feature (via a switch on the PSU). A semi-fanless design, these PSUs operate in a fanless mode when they are below a 50% load.
The PSUs are available in 750 and 850 watt configurations in black, and an 850W white version. You can read more about these new power supplies from Enermax at the source link.
