The Enermax Revolution D.F. 12 is a 750W fully modular ATX 3.1 power supply with a single fan mode, priced at $130 USD from various online retailers and Enermax's website. Despite its 80PLUS Gold rating, it performed closer to Platinum in our tests. We recommend it for its high efficiency and resilience to brownouts.
WHAT YOU NEED TO KNOW
THE GOOD
- Resiliency
The Revolution D.F. 12 750W is very resilient to brownouts, making it a reliable choice.
- Performance
The power supply performs exceptionally well in all areas, achieving great results in our tests with super high efficiency, nearing the 80PLUS Platinum rating.
THE BAD
- Nothing at the time of writing
THE REST
- D.F. (dust free) Mode
Advertised to use Enermax's Dust Free Rotation, self-cleaning technology, which momentarily reverses the fan direction with the push of a button, though Labs were unable to test this feature.
- Overall
We recommend the Revolution D.F. 12 750W for its excellent performance, high efficiency, and resilience to brownouts. It meets and exceeds expectations for its price point.
The Enermax Revolution D.F. 12 750W has a 115mm PWM (pulse width modulation) dual-ball bearing fan. It has sufficient connections to power a CPU, an additional PCIe device, and several SATA devices. The power supply is slightly shorter than the standard 140mm depth. Enermax claims that it is the smallest ATX power supply on the market.
In the Box, it comes with standard items and high-quality accessories such as a PSU and cable bag, cable combs, and a handy tester. The cables are incredibly flexible, partially because they are not bound together, and they have a braided pattern for better structure and management. The power supply features a button the back to momentarily reverse the fan direction to remove dust, part of their 'dust-free' technology, although we were unable to test this feature.
The Enermax specifications webpage lists an operating temperature of 0°C to 50°C, and a storage temperature of -40°C to 70°C, though Labs cannot verify this through testing.

Please note that the above ratings are manufacturer advertised specifications.
The Revolution D.F. 12 750W operates in a single fan mode with the above mentioned Dust Free mode, and is advertised to always operate with a 'hybrid' mode with no fan RPM at low loads. The Revolution D.F. 12 750W is equipped with all of the standard protections and comes with a 10-year warranty.
The power supply demonstrated good and low voltage ripple, as well as excellent load regulation. It sustained all power excursion tests, although the 12V rail dipped below ATX specifications for the 0.1ms excursion, which was marginal and only on one rail we tested. The stability will provide a steady platform for the operation of other components in the computer.
1 of 6
Rated at 80PLUS Gold, it measured 91% efficiency at 50% of its maximum rated load, outperforming similar power supplies and meeting Platinum requirements in most areas. The Revolution D.F. 12 750W performed higher than expected based on advertised specifications, with Cybenetics efficiency ratings consistent with Labs’ findings. It is incredibly resilient to brownout conditions, maintaining the Power Good line with the voltage rails barely dropping through even the longest of test durations.
The Over Power Protection engaged at a maximum of 142% of the rated load, while the 12V rail is capable of 88A, or 141% of its rating. The -12V OCP is high but not uncommon, as the rated amperage/wattage is typically low.
