No, the PSU above is not an SFX model.
“This design maximizes space for airflow inside computer cases while providing robust power according to ATX 3.1 specifications, including up to 235% power excursion. Equipped with a 600W 12V-2×6 cable, the REVOLUTION DF 12 ensures uncompromising performance for high-end graphics cards and cutting-edge AI computers. The REVOLUTION DF 12 also fits perfectly into micro ATX cases, providing plenty of room for efficient cable management.”
These REVOLUTION DF 12 PSUs feature 115mm dual-bearing fans with a self-cleaning function (“Enermax’s patented Dust Free Spin (DFR) technology”), which rotates the fan in the opposite direction to clear dust build-up when you activate the feature (via a switch on the PSU). With a semi-fanless design, these PSUs operate in fanless mode when under 50% load.
The PSUs are available in 750 and 850 watt configurations in black and an 850 W white version. You can read more about these new power supplies from Enermax at the source link.
