Through user’s eyes: Enermax Revolution D.F. 12 122mm (ATX) PSU

There it is, the D.F. 12 PSU is in a finished build

We are now reaching the culmination of the contest for the Enermax Revolution D.F. 12 ATX short PSUs. It is a user review, where the winner describes how he integrated this 122-millimeter PSU into his build. And he managed to do it quite nicely, what do you say? The case chosen is the Jonsbo D31 Mesh SFF case, in which every millimeter saved is a good one. Especially if it doesn’t affect anything and one could note that it is redundant.

What was it about…

In April this year we announced a contest for new ATX 3.1 PSUs – the Enermax Revolution D.F. 12. Due to their extra short length of 122 mm (instead of the usual 140 mm), they fit well into smaller computers, where they can above all else make the installation a little easier.

To be able to win these PSUs, you had to write us a message about how you would use them.

… and what is the result

From the relevant proposals (i.e. in such cases, where there will be at least some advantage from the smaller dimensions) we have drawn two. To date, however, we have the materials for only one of them. The winner has provided a plan with a computer build as follows:

“I would like to participate in your contest for the short Enermax Revolution D.F.12 PSUs. I currently have an unfinished powerful work/gaming mATX setup in a Jonsbo D31 Mesh case. As is usual with smaller cases, the dimensions of the various components affect compatibility with one another. The build features an Intel Core i9 13900 and an Arctic Liquid Freezer III 360mm AIO was chosen to achieve reasonable operating characteristics. In order to fit the 360mm radiator, the PSU bracket needs to be moved to a lower position, however, where standard length PSUs already start to encroach on the graphics card space.

Considering the size of today’s RTX 4080 Super editions, every mm saved on the length of the PSU is really useful and also provides more space for cable management. The Enermax Revolution D.F. 12, which is 18+ mm shorter compared to regular PSUs, simply seems like the ideal candidate to me. It is also nice that it meets the current ATX 3.1 standard, in which a new revision of the 16pin power cable (12V-2×6) with shortened sense pins has been implemented. This should eliminate the risk of the power connector melting when the cable is not properly inserted. According to the photos on the site, the cabling should be nicely pliable, which in conjunction with the included cablecombs will ensure a neat cablemanagment.“

And now Martin’s commentary interspersed with photos from the building process:

In a recent contest organized by HWCooling.net I won an Enermax Revolution D.F.12 PSU in the black 850W version. The main advantage of this PSU is the very short length of 122 mm. Another benefit is the compliance with the ATX 3.1 standard, within which a new revision of the 16-pin power cable (12V-2×6) with shortened sense pins has been implemented. This should eliminate the risk of the power connector melting when the cable is not inserted properly.

I took advantage of both of these major benefits to build a more compact, powerful work/gaming mATX build in the Jonsbo D31 Mesh case. The foundation of the build is an Intel Core i9 13900, which was fitted with a 360mm Arctic Liquid Freezer III AIO cooler due to the excellent price/performance ratio.

As is common with smaller cases, the dimensions of the various components affect each other’s compatibility, and the D31 is no exception. In order to fit the 360mm radiator, it was necessary to move the PSU bracket to the lowest position, where standard length PSUs start to encroach into the graphics card space and the PSU cabling gets dangerously close to the blades of the bottom fans. Considering the dimensions of today’s high-performance graphics cards editions, every mm saved in PSU length is really useful, and it also allows more space for cabling. Taking into account the recent discount, I opted for the most dimensionally modest RTX 4080 Super – the ProArt edition from Asus.

I was pleasantly surprised by the quality of the supplied modular cables, which have an aesthetically pleasing individual braid and, most importantly, are extremely pliable, which greatly facilitated the cablemanagement.

Personally, I don’t like builds which are noisy under full load and I have to say that the PSU didn’t disappoint me in this aspect either. To check the cooling after adjusting the fan curves, I subjected the build to a two-hour load test, where all components were loaded to the maximum and the total consumption of the build was up to 550 W. Even with such a relatively high load, the PSU was not the noisiest component by far.

What can I say in conclusion? Thank you to HWCooling for hosting a series of contests for their readers. Thanks to the latest one, I got a high-quality PSU, which fits my mATX build like a glove.


The owner of the second PSU has not provided the documents to date and unfortunately has not responded to our messages about his situation. We can at least publish his configuration plan for which he wanted the PSU.

“I am writing this email to you trusting that it finds you in the most salubrious of states. First and foremost, I would like to express my sincere interest to participate in the Enermax Revolution D.F. 12 giveaway event. I would love to incorporate the ETV850G into an mATX build with a humble RTX 4060Ti coupled with a Ryzen 5600X and B550m DS3H. In all honesty, I agree that this combination is unremarkable. However, I believe that this build is the most suitable for the general population that wants to build an affordable gaming set-up, while retaining upgradeability. The ETV850G is suitable to be used in the early build since it is consistent and very efficient at low to pseudo-high loads. This makes the PSU an irreplaceable component for the build, especially in terms of upgrade.

Aside from its efficiency and performance, such a short PSU is exceedingly useful for me and my build since it is able to fit in an ITX or a MicroATX case. Hence, I am able to transfer my setup from home to my dorm with ease, since I am currently a university student.

The build is listed below:

  • B550m DS3H
  • Ryzen 5 5600X
  • Lexar NM790
  • Lexar Thor 2× 8GB
  • RTX 4060Ti OC Gaming
  • Tecware Forge M Omni”

In case the other contestant delivers the materials sooner or later, we will be happy to add them here. And we will highlight this article again.
