Lately I have been using OCCT for testing PSUs. OCCT is a CPU benchmark program that maxes out the CPU in a timed test. The benefit for PSU testing is that the program makes charts of various results, including +12v. For some reason, OCCT doesn't find the correct Winbond sensor that ASRock uses to measure +12v. Not a big deal, I just have to tell you what happened rather than being able to show you on a chart.

I connected my trusty multimeter to the Power-Mod 700. With the system at idle, the +5v voltage was 5.01, and +12v was 12.02.

To stress the system, I opened several applications, including defragging the hard drive. I launched Sandra's Burn-in, set to run only Processor Arithmetic, which will max out the CPU. The +12v dropped from 12.02v to 12.00v, a very satisfactory flutter, and expected on a medium sized power supply with multiple +12v rails.

Next, while still running Sandra, I launched Ozone3D's FurMark, an OpenGL fur rendering benchmark, which maxes out the GPUs by a video of a moving furry doughnut. The +12v dropped to 11.98, with the occasional momentary drop to 11.97. Not bad at all for a multiple railed 700 watter. I ran the test several times and the air coming from the power supply never got really hot, nor did the PSU fan ever ramp up. The Power-Mod 700 remained silent for the entire testing.
