Introducing: Enermax MAXREVO - power plant at its best

Nowadays, they don’t like to produce kilowatt feeds, which is why. And this is nothing but the trend we have seen in recent years, which has aimed to improve efficiency instead of ever higher wattage values.

These years have been marked by ‘greening’, which we admit is a good thing. It doesn’t matter at all how much energy a power supply spends to run the machine and how much to heat our room. This trend is the reason why we have encountered fewer high-power units, typically above kilowatts, for some time. The cart is moving and time is running out, so pretty slowly we get back to the point where it is no longer enough to improve efficiency, even if, as with the Enermax unit now being introduced, the manufacturer no longer wanted to jump to the 80+ level .

We typically don’t buy a power supply for a year or two, except maybe some fanatics who like to replace their machine every six months from a spouse or power supply. The time spent in longer use makes you think a little before you buy, as we have to calculate that the energy hunger of the machines will not subside over time. This is true, at least, when we think of power plants, structures with multiple video cards, multi-core processors. And if so, we can do two things. Either we buy a feed in advance that will serve us for a minimum of 4-5 years, or we really reconsider the replacement with each machine expansion. Enermax MAXREVO may be suitable for many years of use.

After the Enermax NAXN units presented in our previous power supply, we now have a real, unadulterated Enermax power supply, both on the outside and, more importantly, on the inside. Due to the shortness of time, we did not have the opportunity to test now, as we had to pass on quickly, but it is likely that in a later article in a printed press on another page, colleagues will have time to take the necessary measurements. We now confine ourselves to the external and, of course, internal presentation of nutrition.

From the first half of the introduction, everyone can guess that this Enermax piece is not everyday hardware, and whoever thinks so is right. In addition to the name MAXREVO, there are two other markings on the packaging. One is the power supply, which is not less than 1350 (!) Watts, the other is the 80+ gold logo. We hope that this data has already caught your attention, believe me, it will be worthwhile to turn further!

The size of the power supply box is roughly four times the size of a standard power supply box. We can say it is huge, and its weight is not ordinary either. In addition to the brand and type designations, we are really interested in how much and what quality of information the manufacturer provides us with.

Enermax didn’t save on info, though there was plenty of room to store a lot of data because of the size of the box. In addition to the specification tables, you will also find a list of key capabilities, which you can read about in a little more detail on the next page.

Opening the box - although it was conceivable - it appears that the power supply is not nearly as big as the packaging, as the cardboard also hides three drawers. The top full-width deck has cables and two bags to store unused strings.

Underneath one, on the right, an extra gift fan winkes at us. Below the fan you will find cable ties and a description of the unit purchased. The power supply itself is located in the left drawer.

With the power out of the box, it immediately becomes apparent that despite the high performance, the external dimensions are not much larger than we would be used to with a mid-range unit, which quantifies 180mm x 86mm x 150mm. The cover has been given the “dusty” finish that is more common than the more expensive Enermax units. Interestingly, the gray casing is all gold except for the modular connectors. On the power side, the name, the surface surrounding the fan, and of course the brand name also shine in a golden light, which of course tries to highlight the quality.

As you can read, we get a whole drawer of cable. This doesn't say so, but when photographed, it already shows what a lot of cables mean, and it can be seen in the picture above. I won’t even list them, just look at the table in the specification. Here are:

{jospagebreak_scroll title = Abilities and Internals}

After the presentation of the packaging and the appearance of the food can come the more essential part, the capability and the internal structure. While the outside is more about the eye, the inside is already about operation.

Let's start with some more interesting abilities! As you may have read before, the simple 80+ efficiency was no longer the case with this premium unit. According to the data on the box, with a load of 20 to 100 percent, the efficiency is between 88 and 94 percent, which is all we can say, wow!

Az ErP 6. indicates that the unit is consuming less than 1W in standby mode.

A DXXI Ready marking meaning is not entirely clear to us, if anyone knows what, please indicate! What is certain is that these are some kind of new generation graphics cards that use a 6 + 2, i.e. 8-pin power connector. (Our subsequent reasoning suggests that DXXI might want to be DirectX 11. Let's say it's incomprehensible why Roman numerals were used on the one hand, and why support for DirectX 11 cards is such a big bang on the other.)

A Server Ready marking indicates that MAXREVO can also serve multiprocessor systems.

A CordGuard a small metal fastener that comes with the power in the box. This can be hooked into the holes under the 230 wire on the back of the power supply and snapped onto the cable. Your job is to prevent the cable from slipping out of the connector.

A HeatGuardperhaps more people have heard of it, if only because NAXN diets knew it. This is an overheat protection that continues to run the power supply fan for 30-60 seconds after the machine is stopped.

There's another Guard, this one SpeedGuard, which is the noisy name for fan control. The point, of course, is to rotate the propeller as little as possible to produce as little noise as possible.

In addition to the capabilities listed on the box, there is one important thing to mention, which of course can be seen from the specification table below. And this is nothing more than that there are no less than six 12-volt rails in the power supply.

Unscrew the power quickly!

After removing the cover, we see one, if not the most tidy, cleanest of feeding interiors. The placement of the parts shows an exemplary order, the soldering of the implanted parts is first class. Nothing wobbles, the capacitors are sure to sit in place.

It is striking that there is surprisingly little wiring compared to standard power supplies. This is due to one of the most appealing innovations in the power supply. We have become accustomed to the fact that we usually find the primary and secondary sides crosswise under the cover, but at MAXREVO the view is completely unusual. On one side of the usual, the primer falls on the other side, instead of the secondary one, towards the inside of the machine, the primary side, towards the back side, the secondary side. As a result, the distance is shorter, shorter and less cables are required between the PCB of the modular connectors and the output side, resulting in less energy loss.

The current path in the power supply starts through a unit of three coils and two condoms, which performs the filtering. Then we find the rectifier bridge in the middle of the edge of the primary side, which also got a small heat sink.

In the same way, the APFC part has its own rib, where four MOSFETs and a boost diode work. Below the rib, next to the power cover, we find the control of the APFC on a vertical board, and on the next vertical circuit board there is a TI PWM unit which performs the function of controlling the bridge.

The three large filter capacitors are Panasonic and Matsuchita, respectively (330 μF, 400 V, 105 ° C).

Behind the condes we find the main transformer made by Rong Chyuan, which has a denser winding than usual, which is why we managed to save a lot on the size. In addition, according to the factories, not only the size but also the heat dissipation has improved, so that despite the smaller size, the transformer will not burn.

Behind the transformer is the secondary side, where a MOSFET for the six 12-volt rails resides on a heat sink. This is followed by two choke coils and 10 smaller filter capacitors (RUBYCON 1500uF, 16V) working under the +12 volt outputs. After the capacitors, we only find the circuit board of the modular outputs.

Overall, the structure of the feed is exemplary, and changing the placement of the primary and secondary sides is a very good idea. The only point in question is whether proper airflow can be established with this arrangement. Suspiciously so, in which, of course, the 140-millimeter, more precisely 139-millimeter air driver also plays a big role. This is an Enermax ED142512S-DA fan, which can vary between 900 and 2000 rpm anyway. High and deep cut ribs were used in the feed to promote good heat dissipation.

{jospagebreak_scroll title = Summary}

Enermax MAXREVO can be called a top hardware without exaggeration. The accessories, the cables, the packaging, and of course the power supply itself tell even the uninitiated eye that here we are getting quality for our money.

Removing the food casing only intensifies the feeling. An exemplary order welcomes us inside the box. Rotating the panel, repositioning the primary and secondary pages seems like a good idea.

As I wrote in the introduction, we did not have time now for the test, but we did not miss to browse the tests of the larger foreign sites (we have the power in Hungary for the first time). Based on this, we can say that the testers were not completely satisfied with the performance of the feed. More specifically with the power yes, because although officially the unit is 1350 watts, the peak load can reach up to 1620 watts, which the manufacturer also indicates in the data. The problem was more caused by fluctuations in different voltages during the tests. These values ​​fell within the limits of the ATX standard in most cases, but in some cases, typically near peak loads, they managed to go below them.

What can we say about MAXREVO in summary? On the one hand, it is terribly expensive, since the Bluechip store they are currently asking for 108 thousand forints, of course gross. The question in each case is whether a particular product is worth the price or not. Well, in the case of MAXREVO, we have to make the usual statement again. For those who need this performance, it is definitely worth it. It’s superfluous to everyone else, as an average home configuration can hold up to a third of the maximum power you can get from MAXREVO. However, if you need it, if you have the frame on it and you don’t regret a hundred springs on a power supply, then don’t hesitate to buy it! You will have a peak power supply that will have few people in this country and that will serve all your needs for many years to come.

The power supply is a From Bluechip we got to the presentation, thanks for that!
