Build Quality
The Enermax REVOLUTION D.F. X 1050W features a single 120mm fan design like many other offerings on the market that has come to be the preferred standard for quiet cooling environments due to the ability to move a larger volume of air at slower speeds than a smaller diameter fan. While great for quiet computing environments the key criteria in our evaluation are whether or not the cooling solution is sufficient, not necessarily its sound level or form factor.
External Build Quality
The external build of the Enermax REVOLUTION D.F. X 1050W looks much like other ATX12v-sized REVOLUTION branded Enermax units that have been produced over the last few years. It also conforms to much of what has become standard among enthusiast power supplies over the last 10+ years or so (the layout is standard for a single overhead fan design with APFC and modular cables).
The finish we see today is a heavily textured almost powder coat-like black finish that should be durable. The unit is further branded with the unit name and Enermax branding via a printing process as opposed to stickers and this is nicely done. The only thing that could be negative here is that it is very monochromatic. That said, how much color is needed to get your point across? Especially with something like the modular interface which we see labeled today. Sure, it is just white lettering, but it is complete, so it is completely functional, and much appreciated.
The Enermax REVOLUTION D.F. X 1050W comes in at a total length of ~5 1/2 inches while the cables come in at a length of ~18″ to 28″ to the first or only connector. Additionally, the cables are all the FlexForce-style cables.
Internal Build Quality
Once we open the top of the Enermax REVOLUTION D.F. X 1050W, we see a rather sparse unit (especially given the unit’s capacity of 1050W) that looks a bit like a modified version of the platform used by the previous REVOLUTION D.F. 850W unit which was based on the CWT GPU platform. However, I can’t find an exact match for this unit today. That said, the topology is a half-bridge resonant LLC primary and a secondary where we have synchronous rectification with DC-DC VRMs for the minor rails.
The heatsink layout features what appear to be just three heatsinks (one larger black ones on the primary side and two smaller bare aluminum ones on the secondary side) installed today. These heatsinks are paired with a 120mm FDB bearing fan carrying the Enermax branding rated at 0.28A at 12v. When we look at the back of PCB, we see the soldering here is borderline excellent.
On the primary side, the REVOLUTION D.F. X 1050W input filtering begins upon the housing itself with some X capacitors and Y capacitors and then trails onto the main PCB with coils, x capacitors, and y capacitors. The bridge rectifiers are next and they are sandwiching a fairly large heatsink. As we move on to the primary side proper, we find a coil followed by the APFC power components and the main switchers on a heatsink. Next to this heatsink are the main input capacitors which are provided by Rubycon. These capacitors are rated at 450v 390uF 105C each.
On the secondary side of this unit, things continue to be very sparse today. In this area, we find that the main transformer is rather centrally located and that happens to be right by a pair of heatsinks. These heatsinks are used by the MOSFETs. The DC-DC VRMs are seen here on the main PCB by the modular PCB. In front of this PCB, we find a number of standard electrolytics provided by Rubycon and Nichicon as well as solid capacitors provided Chemi-con and solid capacitors provided by FPCAP. Moving on to the modular PCB, we see that the PCB construction looks very nice and there are more Chemi-con and FPCAP solid capacitors here.
Build Quality Summary
Today’s Enermax REVOLUTION D.F. X 1050W is the second power supply we have seen from Enermax and, at 1050W, it is larger than the last unit we have seen by capacity. Things seem to be starting off on the right foot as this unit looks like a very well-built product with a lot going for it. The exterior of this unit is well built and it looks like most modular overhead fan units these days while carrying the freshly revised Enermax REVOLUTION D.F. X branding and finish.
This is coupled will all FlexForce style cabling which is nice to see. When we move to the interior build quality, we see a modern design that is generally well-executed even though it is very sparse looking for a 1050W unit. The integration is very well done in spite of a very few little issues with the soldering (and I mean very small issues there).
The component selection is excellent as we see Rubycon and Nichicon standard capacitors as well as Chemi-con and FPCAP solid capacitors today. We also saw an Enermax “Twister Bearing” fan which is another solid addition to the build quality. With this all looking very sorted out to start with, let’s move on now to the load tests and see how this unit does there!
