Enermax MaxRevo 1350W Power Supply Review

Enermax has long been a favorite of ours when it comes to power supplies for heavy hitter enthusiasts pushing huge system wattage loads. Today it is launching a new flagship product that comes to up touting a huge 1350 watt usage rating. Does Enermax continue its top shelf legacy?

As we already know the Enermax MaxRevo 1350W features a single 139mm fan design that is used in the same vein as 120mm fans in that they can provide for quiet cooling environments due to the ability to move a larger volume of air at slower speeds than a smaller diameter fan. The 139mm fan is just short of the largest diameter fan we are likely to see in ATX power supplies given the physical constraints of the form factor. While great for quiet computing environments the key criteria in our evaluation is whether or not the cooling solution is sufficient, not necessarily it’s sound output level or form factor, although we certainly listen for offending units.

The exterior of the MaxRevo 1350W carries on the tradition we have seen from the previous Revolution power supplies with its general form and heavily textured finish. As we have stated before, while this surface finish is somewhat reminiscent of "spray on truck bed liner" it is a very durable powder coat application and is what we believe is the best finish going on consumer units today. The color choice here is a again a subdued grey but this time it is trimmed with gold lettering (due to the units claimed "Gold" efficiency) lettering and stamped-in arrow designs. The top of the unit is dominated by its 139mm fan while the front of the unit features a fully modular interface which deviates a bit from the semi-modular designs of previous Revolution units.

The Enermax MaxRevo 1350W itself comes in at a lengthy ~7 1/8 inches (which is longer than the most recent Revolution85+ 1020W). The cables provide a serviceable length of ~20 to 25 inches to the first or only connector which is certainly long enough for most applications. The sheathing on the cables is the same as in previous Enermax unit's color-wise and once more is a bit short of being complete on both ends of the modular cables. Indeed, on some connectors the sleeving isn’t even close to being complete. It should also be noted that the wiring used on this unit is thicker than average with many of the leads being 16 gauge.

Once we open the MaxRevo 1350W we are left looking at one of the cleanest laid out power supplies we have ever seen. This is all the more impressive as this unit uses a single main PCB and is rated for an output of 1350W. The actual topology used here is based on the topology found in Enermax’ MODU87+ that we reviewed previously but of course incorporates the "new" transformer design from Rong Chyuan among other revisions. From the top here we see a total of four heatsinks used for various parts of the unit and all four are black aluminum. These heatsinks are paired with a Power Cooler (Enermax) "Twister Bearing" 139mm fan rated at 0.75A at 12v.

Looking at the primary side, we see the input filtering begins on the housing itself. It then trails across the front of the main PCB. In the midst of this filtering we find our first heatsink and it is housing the bridge rectifiers. Directly behind that we find the main filtering capacitors which are provided by Matsushita and rated at 330uF 400v 105C each. The two remaining heatsinks on the primary side house the APFC components and switching transistors. Lastly, when we flip the PCB over we see one of the better soldering jobs we have seen from Enermax in recent history. Speaking of recent, the PCB is screened with a February production date.

Moving over to the secondary we see the much advertised Rong Chyuan transformer in the middle of the unit followed by the secondary heatsink which houses the secondary 12v power components. This is then followed by the two large coils for the 12v output and the large bank of Rubycon filtering capacitors. At the very edge of the PCB we find "Copper-Bridge Array transmission" leading from the main PCB to the DC-DC VRM’s mounted on the modular PCB just as we have seen numerous times from Seasonic with their X-Series units. On the modular PCB, we find that the DC-DC VRM’s are housed here along with a few solid capacitors. All in all, the modular PCB looks well constructed.

Build Quality Summary

The build quality of the MaxRevo 1350W looks to be very good overall. Externally, there is not much new here as this basic layout design has been used before. The fit and finish is excellent again this time and the actual finish itself is incredibly durable and sharp looking. The additional change to a fully modular interface and the gold accenting round out a very nice exterior that’s only short coming are the not very completely sleeved cables.

Once we move to the interior, we find one of the cleanest power supply layouts and one the best integration jobs we have seen to date. From top to bottom Enermax has really worked this unit over and they even did a good job on the soldering and modular interface. The components used to stock the power supply are also high end including Matsushita and Rubycon capacitors as well as the "new" transformers from Rong Chyuan that Enermax is so proud of. All in all, this is perhaps the best built power supply we have seen from Enermax and one of the best built we have seen overall, particularly when we consider that it is a 1350W unit. Let’s move on now and see how this fine looking unit performs!
