Testing (continued):
For a final check on the Silencer 750's performance, the data from OCCT was reviewed after its 30 minute run. As this program runs, it stresses the system and it can monitor the various voltages (with the help of Everest Ultimate Edition 2006 in this instance). The charts below were generated for the 3.3V, 5V, and 12V rails, and as you can see, the total ripple was minimal and the rails are considered stable.
The 3.3V rail had a total ripple of 0.03V (or 0.91%).
The 5V rail had a total ripple of 0.04V (or 0.81%).
The 12V rail had a total ripple of 0.06V (or 0.50%).
PC Power and Cooling advertises a total ripple of 1% on any rail, and this somewhat crude test suggests that the Silencer 750 is definitely capable of maintaining that.
Overall, the performance was extremely impressive. Even with the extra load generated by the Seasonic "Loader" device thrown on top of everything else, the voltage rails wouldn't flinch. They just kept on reporting the same static data, which is what you would like to see. In addition, the Silencer 750 drew about 6% less Wattage on the AC power line, despite having a power rating 50% higher than the reference PSU used in testing. There was just one area where I was a bit surprised... As the load increased, so did the temperature, and the fan in the Silencer 750 ramped up to deal with it. Under a significant load for an extended period of time, the term "Silencer" became less appropriate for this unit. While quite quiet at idle, the noise becomes more noticeable once things heat up.
