The electrical performance of the Enermax Revolution D.F. X 1050 PSU is commendable, especially for a high-performance unit, reflecting a strong emphasis by the design engineers on the primary 12V rail. This rail exhibits excellent regulation, with a variance of less than 0.5% across the nominal load range, and effective filtering demonstrated by a maximum voltage ripple of 40 mV. However, the voltage regulation and filtering on the 3.3V/5V rails are not as proficient, with regulation approximating 1.2% and voltage ripple extending up to 36 mV, though well within the design limit of 50 mV.

As part of our standard testing, we test the primary protections of all PSUs we review (Over Current, Over Voltage, Over Power, and Short Circuit). The protections of the Enermax Revolution D.F. X 1050 PSU engaged normally. The OCP of the 12V rail immediately engaged at nearly 130% of the unit’s maximum capacity, a high figure for such a PSU design.

Conclusion

The Enermax Revolution D.F. X 1050 PSU stands out as a compelling option for those in pursuit of a high-performance power supply unit. The build quality is robust, showcased by its intriguing external aesthetics with a textured paint finish, fully modular cables, and an elegant touch of RGB lighting on the frosted side display. Furthermore, the inclusion of high-quality Japanese capacitors throughout the unit underscores its reliability and durability. Its external allure is matched by a compact and cleanly executed internal design carried out by SANR Electronic Technology (also known as Casecom), a seasoned yet uncommon OEM in the high-end PSU arena. Despite being a relatively rare name in high-end PSU circles, they have exhibited a good design and assembly job, reflecting a blend of experience and quality assurance in the product.

When it comes to power quality, the Enermax Revolution D.F. X 1050 shines, particularly with its exceptional voltage regulation and filtering on the 12V rail. The unit boasts outstanding energy conversion efficiency that transcends the 80Plus Platinum benchmark at low-to-medium loads, showcasing its operational efficacy. However, a noticeable dip in efficiency is observed when the PSU is heavily loaded, relegating it to an 80Plus Gold certification under such circumstances.

Thermal performance of the Enermax Revolution D.F. X 1050 is average, showing a tendency towards higher temperatures under heavy loads in adverse environments. Nonetheless, at or near room temperature, the unit performs well, maintaining good thermal figures. When it comes to noise levels, the unit is practically inaudible at low loads in standard room temperatures, a feature that most users will appreciate. However, as the load increases, particularly in higher ambient temperatures, the noise level rises but remains within a tolerable range for most users. The fan's maximum operational speed is attained before the unit reaches its maximum power output, which could be a concern in high-temperature environments.

Value-wise, the Enermax Revolution D.F. X 1050 stands out as a competitively priced option given its high power output, currently retailing at $135. This price point is particularly attractive when compared to less powerful units from competitors retailing at similar prices. The 10-year manufacturer warranty is a cherry on top, providing a sense of security and trust in the product's quality and durability. The comprehensive set of features, compliance with ATX 3.0 standards, and the lengthy warranty make the Enermax Revolution D.F. X 1050 a worthy investment for those in need of a high-power output PSU with a mix of aesthetic and functional attributes. However, its limited cooling performance and display of thermal stress when the unit is very heavily loaded may warrant consideration for users who plan to utilize this PSU in sustained high-demand settings.

    The female pins are a new design. That's the most important change.
    The adjusted pin length is just a minor tweak, not important in any way.
  • E.Fyll - Monday, November 13, 2023 - link

    The female - and male - pins are entirely the same.
    I have no idea where you picked up that nonsense, probably from some clickbait article of shorts, but, once again, the only difference is the length of the Sense pins and that is only taking place on the equipment's side too. You can read the specifications, they are publicly available. You should not be spreading misinformation.

    I don't know why you'd think those power pins are the same. The whole purpose of the 12V-2x6 plug even existing is to fix the overheating flawed design of the 12VHPWR plug. Having a couple of shorter signal pins ain't gonna make the slightest difference to fixing it.
  • MamiyaOtaru - Tuesday, November 14, 2023 - link

    you're sort of right. It' not really fixed. But the shorter signal pins do help ensure it is inserted all the way before it runs current. Still has deeper flaws though
  • evanh - Wednesday, November 15, 2023 - link

    Yes, 12VHPWR plug has deeper flaws - weak female power pins in the plug. And that is what is really being fixed with the introduction of the replacement 12V-2x6 plug.

    12VHPWR cables, both supplied with PSU and as adaptors, need to all be recalled and replaced with the newly introduced 12V-2x6 cables. All manufactures should be doing this immediately to stop the on-going damage to graphics cards.

    "Ball-bearing engines are very reliable but not the quietest, however the PSU features a semi-passive design that will completely stop the fan while the load is low. "

    Doesn't look vibration isolated from chassis.

    For the price it's hard to argue with these results, but I can't help but think, realistically, this should be considered an 800-watt PSU. It's capable of 1050w but it's operational sweet spot and efficiency are more in-line with 750-800w units, where continuous current will never exceed 80% load, or 600-650w. Since load is really inconsistent during most use cases (gaming, burst performance, etc) it's good to have the overhead and potential for 1000w+ but if you have a system design that often hovers around 650w load (like an RTX 4080 + i7-13700k) this is among the best candidates out there.
