When it comes to testing a power supply, there are two courses to travel. One takes you down a path using a device to stress out the PSU and provide data regarding the power levels across all three rails. The second, and the one I make use of, utilizes an actual test system to give a more real-world account of what the power supply is capable of. While both methods have their merits, I prefer to use an actual computer to more closely resemble the manner of use that you, the potential customer, will put the product through.
That said, let's take a quick look at the test system. At the request of readers, I have beefed up the system to put a more realistic strain on the power supply.

While this isn't a Quad-GPU setup, we are certainly in the realm of having a system that is going to put a significant power drain on any power supply. Testing will consist of checking the power levels across all three rails at idle and again while the system is under stress. This should give us a good look at the capabilities of the power supply being tested.
When putting the system under load, I usually expect to see some variance between voltage levels when compared to idle loads. It is customary to see differences of up to .04-.06v on the 12v rail and slightly less on the other rails, but this Cooler Master unit is extremely stable even under stress. I dropped a whole .01v at the 12v rail and at the 5v rail and the 3.3v rail remained exactly the same as idle. Now granted, I'm not running a Peltier cooler monstrosity here, but I'm putting a good deal of load on the power supply and it looks to be laughing back at me. This is very nice and bodes well for all you power users out there.
