Enermax MAXREVO 1350w PSU Review
Simulated Load Results (Tables)
If you’ve seen the simplified graphs over on the previous page you will undoubtedly already have a good idea of how the MAXREVO 1350w performs. However, certain results from the test can be too difficult to incorporate into the existing graphs, and for this reason all of the result data is also provided in the table format below.Â
All testing is conducting using OC3D’s trusty SunMoon SM-268+ DC load tester. This equipment is capable of placing a user specified load on all of the PSU’s rails (+3.3v, +5v, +12v, -12v, +5vSB) up to a maximum load of 1680w. However, as the maximum load for this device on the +12v rail is restricted to 75A we also had to call on additional help from our Analogic Series 2000 DC load tester in order to make up the remaining 25A, to test the unit up to its load limit of 100A. As usual, all testing is conducted at 50°C (±5%) with the results being recorded using a Fluke Multimeter and Thermostat.

Although most of what I’ve wanted to say about the performance of this PSU has already been covered over on the previous page, it’s hard not to point out again the fact that the MAXREVO managed to sustain a whopping 1705w output with a 131A load on the +12v rail without too much of a hit on performance. Furthermore it was actually capable of holding a peak of almost 1800w for several minutes before shutting down in a graceful manner.
Efficiency is also a highlight of this unit as previously mentioned, with both test #2 and test #3 hitting the mid nineties. This is exactly where the majority of the efficiency (and rail stability) is required because most people are likely to run a 1350w PSU somewhere in the middle ground, rather than at either of its extremities.

In much the same way that the +12v rail is the most stable voltage-wise on the MAXREVO, the same can be seen when it comes to ripple suppression. All the way from test #1 to test #4 the scope reads a maximum of 20mV, and only when pushed beyond its rated output in the TMax1 test does it finally increase slightly to 28mV. This is quite frankly an astonishing result, and possibly the best/most consistent +12v ripple result of any PSU tested here at OC3D.
BUT, and that’s a big J-Lo sized but…the +3.3v and +5v rail results aren’t anywhere near as excellent. While both of these rails are becoming less important in the modern PC it would almost seem like Enermax concentrated all of their efforts on the +12v rail and somewhat neglected the others. Of course they are still well within ATX specs, but at 36mV and 40mV respectively, they fall short of the results from other premium brands.
