Enermax Revolution D.F.12 750W PSU Review

If you want a compact ATX PSU, then it doesn’t get any smaller than the Enermax Revolution D.F.12 750W which measures only 122mm in depth. This is also an ATX v3.1 unit, supporting all current and upcoming generations GPUs. 

The Enermax Revolution D.F.12 750W is included in my best ATX v3.x & PCIe 5.x PSU picks article.

I have already evaluated the Revolution D.F.12 850W, so it was time to look at the smaller member of the line. It has the exact compact dimensions, measuring 122mm in length. I guess it doesn’t get any smaller for an ATX PSU. According to Enermax, the PSU’s small size offers significant benefits: it easily fits into smaller chassis, more space for cable management, and extra volume out of the airflow’s way. I can agree with the first two but not for the last since the PSU’s airflow is severely impacted by the small PCB size, while in most chassis, there is a dedicated PSU compartment, so the PSU’s size doesn’t affect the chassis’ airflow. On the other hand, the small PSU PCB leads to restricted airflow at its internals, increasing fan speed and noise output.


This PSU also has a Cybenetics Platinum rating and a Cybenetics Standard+ (35-40 dB[A]) noise level. The 120mm double ball bearing fan has to spin at high speeds to remove the heat from the PSU’s internals, so it doesn’t operate quietly. The unit is made by RSY, a good OEM that handles production for other major OEMs, including Super Flower and Seasonic. It seems RSY doesn’t want to only help in the manufacturing process of other OEM models but desires to enter more into the PSU market with its platforms.

I am looking forward to having another competent OEM in the field.
