Installing the Enermax Revolution85+ is as straight
forward as any power supply should be. There is one issue that
I ran into, but its exactly the same issue I've had with every
power supply I've tried in just about every full-tower enclosure
that mounts the power supply on the bottom. If you plan on
routing your cables behind the motherboard tray with the cable
management cut-outs then you're going to need extension cables
for the ESP+12V lines. Sure it's a bit of a hassle and adds a
slight cost to the build, but its really worth it keep those
cables from out of sight and stretching across the video cards.

Oscilloscopes are about the only practical device to analyze a
voltage signal to determine its accuracy to specification and
its cleanliness. An Oscilloscope would also represent a purely
laboratory based test. While good on paper, it doesn't represent
the quantifiable results of operational testing. So, I'm going
to use the OCCT and its Power Supply Testing module to graph the
As I mentioned earlier, the Revolution series power supplies
were found to have an incompatibility issue with the EVGA X58
Classified E760 motherboard.
thread is just one of many that touched on the subject. The
issues have been resolved and the test system matrix shows, I
plan to conduct my test with the E760 Classified.
The margin for fault tolerance on a ATX v2.2 +3 volt rail is
between 3.135 volts through 3.465 volts. With varying CPU load between 65 -
100%, the rail settles at 3.325 volts and hovers there with only minor rises as
the CPU utilization recovers from 100%.
Tolerance on the 5 volt rail ranges from 4.75 volts - 5.25
volts. The 5 volt rail is the hardest hit as it directly feeds the voltage
rectifiers on the motherboard responsible for feeding the CPU. Aside from that,
OCCT reports a high of 5.09 and a low of 5.0v flat. This falls well within the
fault tolerance of the ATX specification and never drops below the 5v target.
Tolerance on our 12 volt rails range from 11.4 volts - 12.6
volts. Again we see some natural fluctuation while the CPU ramps
up and down in utilization. Highest degree of fluctuation during
the high/low utilization rates is roughly .1 volts and stays
well within prescribed ATX 2.2 standards.
