Closer Look and Performance
The interior of the PSU looks exceptional, as in every Enermax PSU I’ve tested. Everything is clean, the soldering is outstanding, and the whole design suggests no problems with overheating any component. I’m repeating this recently as the general quality of PSUs in recent years is very high. As long as the manufacturer advertises 80+ Gold certification or higher and uses Japanese capacitors, there’s a high chance it will be a good unit. Of course, there are differences in cooling and additional features. In the case of Enermax, it was always on the top level, so I’m glad that the new series maintains exceptional quality.
All the visible capacitors are rated at 100°C or more. Many, if not all, capacitors are Japanese, as we can read in the main features and see in the attached photos. The two main capacitors are made by Nippon Chemi-Con. Both are rated at 450V, 390uF, and 105°C. It’s about what I would expect in the 1050W PSU.
The Revolution D.F. 2 1050W uses a dual-ball bearing PFERS-12M fan, rated at 12V 0.28A and up to 2100RPM. This speed is only a maximum one, so we don’t have to worry that the fan will be loud. It works in a semi-passive mode – under 20% load, it turns off, and above, it’s still barely audible up to at least 50%+ load. We couldn’t really hear the PSU fan during our tests, as the typical ambient noises were louder.
Performance
Tests were performed on the Intel platform, containing the overclocked i7 14700K CPU, ASUS Z790 APEX motherboard, overclocked Colorful RTX4080 Advanced OC graphics card, and additional components to bump the wattage. The peak wattage is around 870W.
There were no stability issues during all tests. The efficiency of the Revolution D.F. 2 is exceptional. The +12V voltage was nearly perfect under load, but we couldn’t reach 1kW+ with our test rig.
In idle and during the mixed load tests, the PSU was silent. Under full load, the fan was barely audible, as I already mentioned earlier. There are no additional noises, coil whine, or anything similar. The culture of work is on the highest level.
The mixed load test will be the closest to the daily usage, which is about what we can expect during less demanding gaming or some more demanding office tasks. During this work, the PSU is just perfect. It’s quiet and delivers stable voltages.
The PSU is designed to work with the latest graphics cards from Nvidia and AMD. The new Nvidia graphics cards use the 12VHPWR cable, designed to handle 600W. Our RTX4080 requires such cable, and we had no problems using the one that comes with the Enermax PSU. It confirms that the plugs and pins are solid and shouldn’t cause any issues with high-wattage GPUs.
The Revolution D.F. 2 1050W is precisely what most gamers need, and it’s not hard to recommend it.
