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 PLATIMAX 1000w 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.
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 provide the extra grunt for our max load testing.
As usual, all testing is conducted at 50°C (±5%) with the results being recorded using a Fluke Multimeter and Thermostat.

To reiterate what has already been said over on the previous page, the Enermax Platimax manages excellent voltage stability on all rails under both normal usage scenario's and also our additional cross-load and max-load testing. The highlight of the testing however has to be the fact that the Platimax 1000w was able to pump out 33% more power than what was written on the box. At 1333w the +3.3v and +5v rails did start to show signs of some strain with the voltages dipping to their lowest outputs, but the rock solid +12v rail continued to supply a whopping 98.20A with a voltages just a smidgen below 12.0v.

Ripple refers to the small fluctuations in voltage that occur in all PSU's on a millisecond scale. Large quantities of ripple on a PSU can damage or kill components in your PC over time and therefore testing a PSU's performance in this area is just as important as any other part. ATX specification states that ripple should be no higher than 50mV on the +3.3v/+5v rails and 120mV on the +12v rails, so what we're looking for in the screenshots above is for all rails to stay well within these limits during Test 1-4 at the very least.
The good news is that they do, and despite the ripple results not being what I would consider 'excellent', they are certainly in the 'very good' territory and perfectly acceptable for a high-end PSU. In fact, maybe I'm being a tad harsh on the Platimax because even when overloaded by 33% (1333w) in the TMax1 test all of the rails manage to remain within specifications.
Now to sum everything up....
