Enermax Revolution D.F. 12 850W PSU Review

The Enermax Revolution D.F. 12 is a compact power supply, well suited to a variety of chassis, when high power output is a prerequisite. Due to the small physical size the fan is quite aggressive in this supply and temperatures rise a little under higher loads. Nothing to be concerned about, but there are always some downsides when you reduce the physical dimensions.

The noise factor is something to bear in mind however, because if you are building a small system and are focusing on the lowest possible noise levels, then you should look elsewhere. While it is true that many people accept compromises with smaller chassis in regards to noise, I know plenty of people who want a small, very quiet system. I would recommend you look at a fanless PSU, from Seasonic, for example, in that case.

Technically, the unit performs quite well, but it does not really stand out in any key area. The primary 12V rail is strong in our testing, delivering consistent results across the board. Load regulation is pretty good and ripple suppression scores highly across all the rails.

People looking at this power supply will be likely interested in the small size and while we mentioned the noise and cooling downsides because of this, there is no doubt that the Enermax Revolution D.F. 12 850W is one of the smallest, most powerful power supplies on the market. At only 122mm long it really is quite a unique unit in today's market.

Pricing is set at $140 for the black supply, with this white version costing $10 more. Sadly in the United Kingdom we run into the same availability issues that plague Enermax. They sent us a link to Amazon UK (HERE) with a recommended retail price of £129.90 for the black and £146.90 for the white. When we checked before publication, prices showed a staggering £170.09 from a third party seller. We can only hope this will improve over the coming months into the latter half of 2024.

KitGuru says: The Enermax Revolution D.F. 12 850W targets a niche audience of end user, who requires the smallest power supply with high power delivery and who does not mind a little noise. If you can find it at the recommended retail price, it is definitely worth buying.
