Review on Enermax Revolution Certified Supply ERF850EWT by David Crowder

Revainrating 5 out of 5

A detailed look at internal power supplies

The Enermax Revolution DF is one of the highest quality power supplies available today. Unmatched multi-channel design, high-quality Japanese capacitors, outstanding efficiency and performance. The Revolution DF is a wonderful machine. The multi-rail design has some additional advantages, with the exception of the coupe. The main benefit is that multi-rail designs are generally more efficient and provide better protection for your components than the much more common 12V single-rail design, which is likely to detect and respond to issues such as overcurrent protection. You can also give some components their own dedicated bus, so power spikes in one component don't disrupt the rest of the system. This improves efficiency and results in a more stable overclock. The downside is that the design is more premium and it is more expensive to manufacture. You also have to manage the load on the rails yourself. With a multi-rail design, you need to pay special attention to how you distribute the load on the rails. Please note the annotated photo. A 24 pin motherboard cable, SATA and Molex require 12v1 which is 25 amps. An EPS (CPU) cable with 4 + 4 pins requires 12v2, i.e. 25 amps. The 12v3 bus also has a CPU port, but it's best to use 12v2 for the CPU and dedicate 12v3 to PCIe for the GPU. If you have a high-performance graphics card like the RTX 3080 with two 8-pin PCI connectors, it is recommended to split the load on the GPU between 12v3 and 12v4, which are 40 amps each. It does this by using two separate PCIe cables and connecting one to a 12v3 port and the other to a 12v4 port. This will give that voracious graphics card a total of 80 amps, which is more than enough for any GPU. Problems arise because people cannot properly balance the load. It's possible to inadvertently put the CPU and GPU on the same bus, e.g. B. 12v3. If you're dealing with energy-intensive components, you can overload that single rail and disable the overcurrent protection. This is when people think they have a bad block. As mentioned, multi-rail designs are more advanced than single-rail devices if you take care to properly balance your components on the 12V rails. With an 850W device, the rails are pretty solid and you will unlikely to run into problems No matter how you distribute the load. But I can see how a smaller 650w unit can get overloaded if the load isn't properly balanced. Other nice features include all-black ribbon cables. They're a bit more difficult to work with as they're stiff and only curve in one direction, but they look very nice. I also found the fan to be completely silent, spinning at just 400 RPM. The anti-dust function is also good. A button on the back of the device temporarily rotates the fan in the opposite direction to blow out the dust that has accumulated inside. The device also does this every time it is turned on. If you haven't figured it out yet, my opinion of Revolution DF is very high. Not only is this an excellent power supply for the money, it's good at any price. Only the Be Quiet Dark Power and Corsair AXI devices, which are significantly more expensive, can actually be compared with this. Power supplies have always been Enermax's forte, and the company's name is certainly true. Unfortunately, some of their other products like All-In-One Coolers have been overlooked causing people to lose sight of the brand. When it comes to power supplies, Enermax doesn't skip a beat and is the industry leader in the industry.
