Teardown & Component Analysis

In contrast to other well-known brands such as Corsair, Asus, Gigabyte, and many more, Enermax opted to reduce costs by adopting a platform provided by SANR/Casecom. It’s intriguing because we don’t get to see these types of platforms very often. This half-bridge LLC resonant converter + DC-DC topology has high output efficiency and stable voltage regulation. Generally speaking, Aerocool and Kolink PSUS, both of which are well-known for their high-price-to-performance designs, have been known to feature several of these platforms in the past.

Similarly, Enermax has a reputation for utilizing platforms from lesser-known OEMs, but with a crucial condition: they use only top-of-the-line quality components. This approach keeps costs relatively low while delivering a high price-to-performance ratio. By combining these factors, they elevate what would be a merely adequate platform to an exceptional quality one. The result is outstanding PSU performance at a relatively lower cost compared to competitors.

12V MOSFETS are all soldered on the top of the PCB, along with a small heatsink.

The temperature sensor is directly mounted on the 12V MOSFET’s heatsink, which is a really good sign.

The REVOLUTION D.F. X features 100% top-of-the-line 105C rated Japanese capacitors from Rubycon 450V 390uF each, to provide extremely stable and reliable power output for years.

Ultimately, better regulation, lower noise and output ripple, more efficiency, and more effective thermal management are the outcomes of the Revolution D.F. X’s use of cutting-edge LLC and Synchronous Rectifier (SR) architecture. In addition to this, it also features heavy-duty industrial-grade protections, including OCP, OVP, UVP, OPP, OCP, and SCP.

Dust-Free Rotation Technology

The Enermax Revolution D.F. X 1050W PSU features an innovative cooling system designed to maintain optimal performance and minimize dust accumulation. It employs a 120mm Fluid Dynamic Bearing (FDB) fan with a maximum speed of 2,100 RPM and a lengthy lifespan rated for 100,000 hours of use. What sets this cooling solution apart is its “self-cleaning mode,” where the fan’s rotation direction is reversed for approximately 10 seconds at startup. This innovative feature helps get rid of and remove accumulated dust, ensuring a clean state and consistent power supply over time.

Additionally, Enermax’s air guard design enhances cooling efficiency, reduces fan noise, and directs airflow over a cable-free PCB equipped with high-quality Japanese capacitors. The high-pressure blade design enables the fan to generate remarkable air pressure and flow rates while maintaining a whisper-quiet operational level. Furthermore, the semi-fanless technology allows the fan to be entirely switched off at light loads, resulting in an ambient noise level of 0 dB(A) for silent operation. This includes a 6-pole motor and three 3-phase fans that have been meticulously fine-tuned for several critical factors: low noise levels, highly efficient operation, and minimal vibration. 

How Did We Test the Revolution D.F. X 1050W?

At Tech4Gamers, we stand apart by taking a hands-on, practical approach to evaluating PSUs. Instead of relying solely on certifications or synthetic load testing, we put PSUs to rigorous real-life stress tests. Having said that, our custom PSU load tester, designed with high-density power MOSFET modules similar to those in reputable SunMoon/Chroma load testers, allows us to assess PSU performance accurately.

Our focus is on understanding the diverse demands and challenges that PSUs encounter in gaming systems. We evaluate aspects such as voltage regulation, efficiency, temperature performance, and noise levels to provide comprehensive insights into a PSU’s capabilities. This approach empowers users to make informed decisions when selecting a PSU for their specific gaming needs, whether it’s for a high-performance rig or a budget-conscious build.

PSU Load Testing

12V & Minor Voltage Rails Regulation

Loading up 12V rail at 20%, 50%, 80%, 90% & 100% and keeping minor rails that are 5V & 3.3V at constant 25W combined (as minor voltage rails don’t get that much stressed due to the fact that they are mainly responsible for powering HDD, SSDs, RAMs and other minor components on the motherboard and such components require less power compared to 12V rail which is responsible for powering the most demanding & power hungry components such as CPU & GPU)

12V voltage regulation is very tight overall. Enermax has chosen a very capable platform for their DFX PSU lineup, which should be necessary considering it’s an ATX3.0 compatible PSU.

PSU Efficiency & Temperature

PSU efficiency is crucial as it directly relates to wasted energy, both in Watts and heat. Wasted wattage numbers will have a huge impact on your yearly electricity bills, and wasted heat will contribute to the overall life expectancy of your PSU’s internal components, especially Capacitors.

Voltage Ripple Performance

This test will evaluate how well a PSU performs in minor or extreme overclocking conditions. Better voltage ripple performance equates to an extremely well-built PSU with premium-quality components. PSUs’ output voltages are in DC (Direct Current). Technically, this DC signal should have an absolute 0 (zero) frequency (i.e., 0mV), but because this DC is getting generated from various steps whose main source signal is AC. Hence, there’s always some presence of AC voltage signal, called Voltage Ripple. Higher voltage ripples can significantly reduce the lifespan of electrolytic capacitors, as it can give you a tough time and many BSODs if you’re overclocking your system.

Voltage Ripple performance is average. A PSU having the latest ATX specs should perform better in this test. Though this should be a concern for those who want to push their system to maximum & stable overclocking, the Enermax Revolution D.F. X 1050W PSU does offer a competitive price-to-performance ratio and comes with various other appealing features.

Temperatures

In general, the thermal performance of the PSU is satisfactory. Nevertheless, it’s worth noting that the area at the back where the transformer is located experienced a notable increase in temperature, reaching approximately 54 degrees. This observation is somewhat concerning, especially considering that the testing was conducted at an ambient temperature of 26 degrees. While this temperature at the hottest part of the body is a bit worrying, it’s not excessively high.

12VHPWR Cable Performance On Max Load

12VHPWR cable sustained the load of 600W without breaking a sweat at the voltage level of 11.9V.
