Testing (continued):
The first set of results take a snapshot of the voltage rail readings for the two power supplies being compared. During the initial review of the Cooler Master Real Power Pro 1250W unit it was noted that the rails did not flinch regardless of load condition. The same holds true here. At idle or load, all of the rails hold the values shown, even when the multimeter is left to monitor any single rail for an extended period of time. Just about the same is true with the Tuniq Ensemble, and the next set of results will take a closer look to show the minimal fluctuations experienced.
At idle, the Tuniq Ensemble's voltage rails did not budge from the values presented in the chart above. Under the load conditions, the rails were near static, but over an extended monitoring period there were minor fluctuations on the 12V and 5V rails. The next set of charts takes a look at the Ensemble PSU over a 15 minute period while the system was stressed as described on the previous page. The chart indicates that readings were taken once a minute for fifteen minutes, and what it really represents is a constant cycle between the three rails. I would connect to the 12V rail - wait for it to stabilize - take a reading, and then repeat the process on the 5V and 3.3V rail, making sure to get back to the 12V rail in 60 seconds.
What we see is a total ripple of 0.03V on the 12V rail (about 0.25%) and 0.03V on the 5V rail (about 0.58%). While not zero, the values are insignificantly small in my opinion.
