Testing

To test the unit, I’ll be using the following setup:

To make sure that the unit is being tested to the max, I’ll be using everything that my PC has that sucks power. This includes, running CPU Burn-in, playing load music, copying files, and playing Unreal and having as many powered USB devices as possible connected.

I’ll use Speedfan to graph and record the results. I’ll also use a multimeter to read the rails from a molex plug.

3.3v rail - Graph shows 18 minutes

5v rail - Graph shows 18 minutes

12v rail - Graph shows 18 minutes

The full load was started within the first 6 minutes of this graph. None of the rails vary a particularly large amount. The 5v rail is especially stable with it barely varying for the entire testing procedure. It should be noted that the graphs are really sensitive and a rise of just 0.01v will give a peak in the graph. ALL of the rails are WELL within their respective tolerances, in fact the 3.3v rail ± 0.01v (3.31v), the 5v rail ± 0.01v (5.18v), while the 12v rail is ± 0.04v (12.31v). Changes of less than a 0.1 are very commendable, especially under the testing conditions.

The voltmeter read the same as the motherboards on board voltage testing facilities.

The results are slightly less than the Coolermaster iGreen which I reviewed earlier. With that said, the difference is over 0.01 of a volt so its not a great deal. The supply has a similar efficiency to the iGreen but it has a higher wattage and it supports multiple graphics cards which the iGreen couldn't out of the box.
