Enermax has decided to add to its flagship line Platimax two updated models with capacity of 500 and 600 watts. They got additive D.F. after Platimax, indicating technology “Dust Free Rotation” from the fan reverser, each wire modular cables are now enclosed in an individual sheath. The efficiency is still on the 80PLUS Platinum level. In our test lab just entered the power supply Enermax Platimax D.F. 600W (EPF600AWT).
Platimax line from Enermax is present on the market for some time, she became the first completely get certified 80PLUS Platinum. In power (500-1700 W) and equipping Platimax line is focused on high-end segment. Now, in the line of new models in the 500 and 600 watts, which are ideally suited to computer gaming.
During the addition of “D.F.” hiding technology “Dust Free Rotation”. It relies on a large 139-mm fan with the Twister bearing, which is when the power supply turns ten seconds in the opposite direction, then reverses direction to the standard. Thus, the fan is released from the dust that has accumulated on the impeller. Also reviewed the Enermax fan controller, a low speed of about 550 rev / min is maintained at a load of up to 80 percent.
Efficiency remained nominally at the same level 80PLUS Platinum, but most manufacturers with new versions bring small optimizations that usually give some advantage in efficiency.
As for the price, the model D.F. are more expensive than the old or conventional Platimax power supplies, but it was to be expected – they still provide more functions. For Platimax D.F. 500W in Europe will have to pay 120 euros, while the ordinary BP Platimax 500W costs from 95 euros. As for the power supply of 600 W, the version for D.F. will have to pay 130 euros, and the old model will cost 110 euros.
Enermax Platimax D.F. 600W is delivered in a cardboard box, the front and rear which printed the basic specifications, and the power supply unit is packed in a foam.
Scope of supply Enermax Platimax D.F. 600W can be called good. In addition to the power cord you get modular power cables of components and mounting screws, as well as a quick start guide.
Efforts are even cable tightening, as well as small plastic attachment in a separate bag. They can be used to fasten the wires to the modular cables, and stick them to the right places of the body.
Enermax Platimax D.F. 600W appearance corresponds well to other Enermax products. Brushed steel case anthracite has a length of 160 mm, so it will fit easily into most systems. Ventilation grille classic, the center one can see the manufacturer’s logo. In general, the design of high-end power supply can be called a simple yet stylish.
Platimax D.F. 600W supports fully modular cabling, and you get up to four connectors PCI Express. Also, the power supply unit supports eight SATA ports, and six 4-pin Molex. So for a 600 W power Platimax D.F. well equipped.
Enermax Platimax D.F. 600W provides good performance, DC-DC technology can be called modern. According to the secondary voltage of 3.3 V and 5 V admissible current up to 16 A or 15, the total power must not exceed 103 watts. With regard to 12, Enermax selected one line. For it is declared complete PSU power 600 watts. That is understandable, since the secondary voltage due to the DC-DC technology derived from the same line of 12 V. A main circuit voltage transformer provides only 12 W.
As befits a good power supply, Platimax D.F. It contains all the basic protection schemes. Enermax indicates protection against excessively high or low voltage (OVP / UVP), overload (OPP), an overload of individual lines (OCP) and short-circuit (SCP). Overheating protection (OTP) is not integrated, but it is not so relevant for the active cooling of the power supply. In our tests, we checked the operation of the protection circuits. By disabling the secondary voltages observed at a current of 30 A through 12 we were able to load up to 62 A, then the fire protection OPP.
As can be seen on the interior, Enermax compared with older power supplies Platimax without additives “D.F.” I used a completely different filling, clicking on the new contract manufacturer Fortech Electronics. The topology of the new power supply is based on a resonant transformation LLC and DC-DC. Enermax chose capacitors from Nippon Chemicon renowned companies, they all declared with temperatures up to 105 ° C. The main capacitor has a capacitance of 390 microfarads.
Below we estimate the noise level and equipment.
Enermax Platimax D.F. 600W, like most of the premium in the market of power supplies, is claimed to be very quiet. Older units Platimax food were absolutely silent, but worked pretty quiet. Enermax power in blocks D.F. re-establishes a 139-mm fan with a brand bearing Twister, which has proven itself for durability and noise.
A distinctive feature Platimax D.F. DFR is a technology, but in fact it is more marketing. Manufacturer modified fan controller, which is the first ten seconds of the fan spins in the opposite direction. Then, the fan stops and starts rotating normally. Such a step has allowed Enermax declare function “self-cleaning” of the fan, the impeller to accumulate dust. How the technology will be successful in practice – hard to say, because we simply did not have enough time for testing. But the front of the fan impeller and the dust did eventually settles and accumulates. Hopefully, DFR technology will be able to oppose it.
Fan own ED142512W-CA production already met us in previous models Enermax power supplies. Another sign that the technology “DFR” is realized only by means of the fan controller. The minimum rotation speed of 550 rev / min is small, her fan is very quiet, it is difficult to hear, even at close range. Enermax is well optimized fan Platimax D.F. controller, so load up to 80 per cent supported a low speed. In our tests, we got speed of about 560 rev / min, even at the level of load of 80%. And Platimax D.F. 600W continued to work very quietly. When the load increases to 100% speed increases slightly to 800 rev / min. The fan continues to operate very quietly, you can hear only a faint whirring bearing.
The second feature is a proprietary Enermax Platimax D.F. It called “SLEEMAX”. Beneath it hides the individual braided wires all modular cables. Each wire in the bundle is enclosed in its own fabric braid. These cables can be used to purchase unless separately, for example, CableMod. The price of such cables is between 50 and 100 euros, so it’s nice that Enermax could fit into your current budget.
The quality of the individual cables is very good, they are neatly embedded in the terminals without the usual heat-shrinkable film. Enermax believes that such cables are more convenient in practice and provide the best configuration flexibility and braid provides additional protection.
The modular cabling system is implemented flawlessly. We have already mentioned the four available PCI Express connector. Enermax also indicates the length of the 8-pin CPU power cable 70 cm.
The length of all cables is decent, so there are no problems even in large buildings.
Enermax power supply unit has shown good results and equipment, and the level of noise. We were pleased with the individual braiding of the cables in the bundle, but in cases with a solid side panel all this beauty is hidden.
After the announcement of the program 80 PLUS, the last 8 years at PSU market efficiency began to play an increasingly important role. The buyer got a pretty simple criterion to select – 80 PLUS, and the manufacturers have appeared convenient opportunity to differentiate their products through the certification level of efficiency. It’s nice to PSU efficiency that customers now receive several reasons justifying the purchase of a very good power supply. Let’s start with energy saving, which is reflected in the account of electricity, and if you are worried about the environment, you can slightly reduce the amount of combustion of fossil fuels and carbon dioxide emitted into the atmosphere. Also, smaller energy conversion loss leads to less heating power supply components. Finally, a more efficient power supply means more quality components and the latest technology. In any case, we performed quality control of the output voltage as a good power supply should not only work efficiently, but also stable.
Thanks to our test station we can fix the power consumed by the power supply from the wall outlet and power load (imaginary) of the computer that allows you to calculate the efficiency of power supplies. First we look at the effectiveness of different loads, and then move on to assess the effectiveness of a fixed load at three levels.
We begin to measure the effectiveness of very low load-five per cent, the corresponding power of about 30 watts. The power supply is not optimized for such a low load, and therefore the efficiency is not the highest. But Enermax Platimax D.F. still it showed a very good result of 80%. After increasing load up to ten percent, we got 88.4%, also a decent level.
At 20% load test power supply came to the settlement level. We got a very good level of efficiency of 92.4%. The load range of 40 to 60% of power supplies usually give maximum efficiency, our 600-watt Enermax Platimax D.F. max was 93.8% at 40% load. It was nice to see that in the range of 30 to 60% load efficiency of the power supply Enermax did not fall below 93%. After peak load at 40% efficiency level is slowly reduced to 91.6% at the maximum load.
For power supplies, we also had three dimensions, corresponding to the three 80 PLUS certification level (20%, 50%, 100% load) with mains supply 115 V / 60 Hz. The distribution of our test station load does not quite match that of 80PLUS in laboratories, but to use it for an exemplary comparison. Enermax Platimax D.F. 600W efficiency reached 91.6% / 92.4% / 89.1%, higher than the minimum levels of 90% / 92% / 89% Certification 80PLUS Platinum. Only at full load we have very similar efficiency. But at low loads of more important as computer performs underneath longer than at full load.
Equally interesting it is to compare the efficacy in three fixed loads, because it allows to evaluate the efficiency of power units in terms as if they are set to the same configuration. The first load of 90 W corresponds to the old office PC or a modern computer average in idle mode. Enermax Platimax D.F. 600W showed a very good efficacy of 91.6%, almost at the level we tested be quiet! Dark Power Pro 11 550W, which can be considered a benchmark for a given power level. The best results we get except that Seasonic Prime.
If a higher power level 250 W power supply Enermax Platimax D.F. 600W also demonstrates very good results, this time he beat a competitor be quiet! Compared with other models 80PLUS Platinum results are very good, although the 750-watt Platimax still noticeable steps forward. At a load of 500 W power supply Enermax Platimax D.F. 600W slightly losing ground, but with the power class it is to be expected, since the load is close to the maximum. In general, Platimax D.F. He proved to be a fine.
Power supply Enermax Platimax D.F. It showed an excellent level of performance. He came along with other power supply units 80PLUS Platinum, and low load could give results even above average.
The quality of the output voltage is one of the most important criteria for the power supply, no less important than efficiency. The power supply must work stably, the voltage must not “jump”, otherwise it may affect your computer. So we checked the voltage levels at different loads, and evaluated whether they are within acceptable ranges ATX specifications. Recall that the ATX specification permitted deviation of plus / minus 5 percent of rated voltage we just set these thresholds on the charts as the boundary.
In addition, we evaluated the quality of the output voltage using oscilloscope. In particular, we evaluated the high frequency noise and ripple voltages that occur on the output lines of the DC. They are associated with the principle of pulse power supplies, and depending on the design and quality of power supply filters may be smoothed with varying degrees of success. ATX standard provides for a line of 12 allowable ripple 120 mV (peak to peak), and the lines for 3.3 V and 5 V – 50 mV (peak to peak).
According to stability stresses Enermax Platimax D.F. 600W shows good results. In the secondary voltage we get a slight drop of 2.0% and 1.0%. In the line 12 in the range of 10% to 100% of the load voltage decreases by only 0.7%.
Very good results we got over the pulsations and noise. Enermax Power Supply showed maximum peaks 27 and 26 mV on lines 3.3 and 5 V. New records we did not get, but the ripple much lower than the permissible level of 50 mV. Yes, and the user makes no difference how large ripple if they remain below the permissible bar. With regard to the line 12, here we have an excellent level of only 30 mV.
Enermax Platimax D.F. 600W showed excellent results in quality of output voltages. We get quite a stable voltage level for this class of BP, and ripple / noise is small.
Enermax power with Platimax D.F. blocks Platimax refreshed part of the old models. We liked the modular cables for individual braids, you will get regular – we have previously encountered such a function only cable, sold separately. Here Platimax D.F. there is every chance to stand out among competitors. Technology DFR, which includes a small time fan reverse, can be called pleasant, though in practice difficult to evaluate its benefits. However, shortcomings and here we do not see.
Power supplies Platimax D.F. We moved to another platform of the new contract manufacturer, in our tests the new Enermax Platimax D.F. 600W showed himself very well. Efficacy fully corresponds 80PLUS Platinum standard or even higher at a low load. Good quality output voltage. Platimax D.F. It has the necessary protection circuits that we have tested in our tests.
By equipping Enermax Platimax D.F. 600W also showed convincing results. You get a nice set of interfaces including four PCI Express connector and the SATA-eight, which is pretty good for 600 watts of power. cable connection system is fully modular, the quality of implementation of the complaints. As we have noted above, the advantage of Enermax Platimax D.F. 600W is the individual braiding of each wire. Of course, these cables are not all users will appreciate, but Enermax Platimax D.F. 600W saves around 50 euros on a separate set of cables.
The level of noise Enermax Platimax D.F. 600W also proved to be a fine. Before us is not the quietest power supply on the market, but almost the entire load range of the fan speed of about 550 rev / min, it is almost inaudible.
