Final Words & Conclusion

The Enermax Revolution D.F. X 1050 W (ATX 3.0) is a good product. The size is very compact (140 mm long) for the wattage you get here. The exterior looks pleasant (in all black), but the thing is that most of the chassis nowadays have a PSU shroud, which would hide this piece of art behind a metal, so even the provided RGB lighting – is not a selling point. You will find the fanless mode here. The unit comes with a 10-year warranty. It’s an 80 Plus Gold certified PSU, and that’s a typical choice for even the high-end systems (maybe a bit more) from the consumer’s point of view (in terms of efficiency/price of the unit). The 1050 W variant offers a massive power output that should be enough for most users, even the most elaborate gaming setups, with a single graphics card in their system. A PC like the one used in this test (i9 13900K + Geforce RTX 4090) rarely exceeds 650 W power draw.
On the quality side, all is great, and the stability tests also went well. Load regulation is very good for an upper-range PSU, and there was no noticeable droop on the +5V and +12V rails. Ripple suppression is safely within tolerance. The 120 mm fan does well when it’s supposed to spin. It becomes audible close to 70-75% load, so there’s no reason to complain. You get typical accessories in the package, including mounting screws, a power cord, cable ties, a manual, the color sticker, and the PSU jumper. The provided cables are black and flat to neatly and beautifully placed inside the PC case. There’s a 12+4-pin Gen 5 PCIe-compatible cable (capable of delivering 600W).  

A word about efficiency
Like with any other power supply, 50% of the maximum load is where the device is most efficient. The sweet spot of the Enermax Revolution D.F. X 1050 W (ATX 3.0) is around 92% (at 230 Volts). In the case of this particular unit, half of the maximum wattage is 525 W. The average gaming PC with a single graphics card (at least those usually spotted in Steam hardware polls) won’t exceed this value under normal conditions. Don’t overestimate the savings (on your electricity bill) you can make by going from 80 Plus Bronze to even Titanium. You can assume that the build quality of more expensive PSUs will be higher, but the differences in efficiency are not that significant. So, summing it up, an 80 Plus Gold PSU like the Enermax Revolution D.F. X 1050 W (ATX 3.0) is an attractive solution. The price is the 850 W variant - 149.99 USD, and the 1200 W –  199.99 USD, which is not so expensive for a high-wattage PSU. 

Stability
There isn’t much to say about stability. The voltages hold, and this doesn’t change under higher loads. The 1050 W version should be enough for a single GPU (who uses the dual-GPU these days, without SLI support?) like an RTX 4080/4090, even with an Intel Core i9 13900K.

Aesthetics
This Enermax PSU looks good with its all-black cabling. The Enermax Revolution D.F. X 1050 W (ATX 3.0) approach with modular cables lets you plug in only the necessary leads, improving your build’s looks. The Revolution D.F. X(ATX 3.0) case looks nice; its finishing makes it look solid. One of the sides is lit up by the ARGB, which you can control via the button placed at the back of the unit or using the motherboard utility. Still, the PSU shroud you’ll usually have or the compartment for the power supply at the back of the motherboard tray wouldn’t help. A few chassis will allow the appropriate presentation. 

Final words

The Enermax Revolution D.F. X 1050 W retails at 149.99 USD, an attractive offer for a (quite) high-wattage PSU that is ATX 3.0 compliant. The unit looks great and has very compact dimensions (140x150x86 mm). There’s a fanless mode (till 20% load), and the noise operation is low (till 70% load). Speaking of which, it’s a pity that you won’t even see the PSU in most of the chassis, as it would be hidden behind the shroud or at the back of the motherboard tray, so in most cases, that effort wasn’t so much needed. As for the power delivery itself – there’s no reason to be worried; although the SANR (also known as Casecom) has made the platform, the results are more than satisfactory. The Enermax Revolution D.F. X (ATX 3.0) offers good acoustics (as it becomes audible only above 70% load) and solid build quality. In the fan, you can find the Dust Free Technology. On power-up, the fan spins backward to remove dust that may have settled inside the chassis. After 10 seconds, the fan reverts to its normal operation. According to the standards, the efficiency is like it should be for the 80 Plus Gold award. You also get a 10-year warranty, which you would expect in that price range. You also get one 12+4-pin PCIe 5.0 compatible cable for powering up to 600 W GPUs. The cables are a bit stiff, and the fan is rather loud at very high loads – but that’s a bit of nitpicking. This PSU deserves the “Bronze” award for the ATX 3.0 compatibility, compact size, ARGB lighting (it may be an advantage for some, but for others – it can be easily disabled), and satisfactory noise under typical operating temperatures.
