Enermax DF 12 Revolution 750W PSU Review

Meet the Enermax Revolution DF 12 750W

Meet the Enermax Revolution DF 12 750W

We first got to see Enermax’s new Revolution DF series at CES 2024. At the event the company promised easier cable management, full ATX 3.1 certification, ATX 12V-2×6 support, and pre-braided cables. Now that these units are available, we can confirm that Enermax has been true to their word.

Recently, we had a look at this PSU’s 850W White counterpart, and today we are looking at the 750W model. For the most part, both power supplies are identical, boasting the same certifications and feature set. The only change with this model is that it has a 750W capacity and it is black.

Smaller than your average PSU

Enermax’s DF 12 Revolution series is 122mm long, making it smaller than standard ATX power supplies. This trait makes this PSU easier to fit inside most PC cases.

The lessened length of this PSU gives users some additional room for cable management. The space under a PSU shroud can hide a lot of spare cable length, and this shortened PSU maximises this potential space.

Enermax Revolution DF 12 750W PSU Specifications

The Enermax Revolution DF 12 750W power supply ships with both an 80+ Gold and Cybnetics Platinum efficiency rating. As the newest PSUs in Enermax’s Revolution range, this series of power sup[plies are both ATX 3.1 and PCIe 5.1 rated. This rating guarantees that this power supply will be able to handle power surges of 235% for short durations.

The Revolution DF 12 series ships with fully modular cables, all of which are sleeved. This PSU also ships with a 27-piece cable comb kit, which will allow users to keep their cable management in order and make their PSU cables look incredibly neat.

Enermax’s latest PSUs all come wrapped in fabric bags, giving their units a premium feel. There are separate bags for the power supply itself, and its included cables. These bags are great for storing cables for future use, and for repackaging the power supply if you decide to give it away or sell it later down the line.

Enermax Revolution DF 12 Inputs and Cables

Below we can see the main power terminals on the Revolution DR 12 850W. We have one 12V-2×6 connector, multiple PCIe/CPU power outputs, and two SATA or 4-pin Molex power outputs.

At the rear of the Revolution DF 12 850W is a “D.F. Switch”, which allows users of this PSU to make use of Enermax’s patented “Dust-Free Rotation” (D.F.R.) technology. This makes this PSU’s blades spin in reverse for a short time to help minimise dust accumulation. This PSU’s fans will not spin under 50% loading. This means that this 850W model will only have its fans spin when over 425 watts are drawn from the unit.

When looking at the cables for this power supply, we kept thinking that “this feels very ASUS”. To us, it looks like Enermax is using the same cable supplier as ASUS are for their ROG Thor series of PSUs. All cables are black, individually sleeved and perfectly match each other. You’d be surprised how many PSU makers have non-matching PSU cables, especially when it comes to 12VHPWR or 12V-2×6 power cables.

Below we have a white 600W rated 12V-2×6 cable. As mentioned above, the cable’s main power pins are sleeved, but its four sense pins use a ribbon style cable. It is a shame that these cables can’t be made to perfectly match the others. That said, this is a minor gripe, and replacing a 12V-2×6 cable isn’t an overly expensive thing if it bothers you.

Cable Management

Supplied with this PSU is a kit of 27 PSU cable combs. Owners of this PSU can use these combs to tidy up the cables inside their systems. If you want a neat looking system, a kit like this in invaluable. Thank you Enermax for including this!

Alongside cable combs, this PSU also comes with a PSU jumper, which is useful when you need this PSU to deliver power when it isn’t connected to a PC. This is a useful component when you need to power liquid cooling pumps of other components. Again, this is a good add-on, and a clear sign that Enermax wanted to give users everything they need. You won’t need a paper clip to jump this PSU!

Power Efficiency and Ripple Testing

Voltage Ripple and Efficiency Testing

When reviewing new power supplies at OC3D, we use our dedicated SunMoon PSU Tester, one of the most expensive (if not the most expensive) tools in the company’s arsenal. Here we can see exactly how well a unit functions. We look at both a PSU’s efficiency and power stability. To do this, we utilise bespoke PSU testing equipment to give us an in-depth look at each power supply’s performance. This kind of data collection is not possible when using a PSU with standard PC components.

Power Efficiency

Enermax D.F. 12 Revolution 750W performs as expected in our efficiency tests. The PSU is 80+ Gold rated, and it delivers similar efficiency levels to similar units. However, it is worth noting that the 850W model is notably more efficient than its 750W counterpart.

Voltage Ripple

Voltage ripple is often underlooked by consumers, being best described as the stability of specific voltages that the PSU delivers. A PSU with bad ripple will see voltages vary a lot more. In extreme cases, this can can damage components or shorten their lifespans. Voltage ripple stability is one of the many reasons why you should buy a high-quality power supply. That means buying from a reputable brand and avoiding anything that isn’t 80+ certified.

An important thing to note here is that none of the PSUs in this graph are “bad”. Even bottom of the chart units like the original Corsair RM1000 (2014) bring usable within your system without any issues. We used this specific power supply within one of our main workstations for years, and we had no trouble with it. As we said before, only extreme levels of voltage ripple is dangerous.

When it comes to ripple, the Enermax Revolution D.F. 12 750W delivers strong results. No, this PSU doesn’t sit amongst the best power supplies that we have tested, but it keeps ripple under the 20 mV level. There are many 80+ Gold rated units that have much higher levels of ripple than that.
