| Cooler Master iGreen Power 500W Power Supply Unit

Testing:
In this picture you can see how my system looks once the iGreen is installed with cables routed where possible. As you can see the extra connectors are tucked away at the top of the case (which would be unnecessary if it were a modular power supply).
To test the idle and load voltages of the Cooler Master iGreen Power 500W, I installed the following equipment for the respective conditions:

The idle condition was established by powering the base system at default speeds and voltages with no applications running for a period of at least 30 minutes. The load condition was established by loading the system up with components and fans, while Folding@Home and SiSoft Sandra 2005's Burn-in Wizard ran for a period of at least 60 minutes. In addition to these stressful applications running, the loaded system was overclocked to add more demand to the power supply. The table below details the idle and load conditions:
Here you can see both the idle and the load voltages. There was a slight drop in voltages from the idle to load readings, however, once the voltages dipped, they did not fluctuate from these readings in the five (5) readings I took. The only concern I have is the low power on the 5V+ rails, but thankfully this is still within the +/- 5% tolerance.
The next chart compares the load voltage readings of four power supplies on the same test system. All of the values are well within an acceptable range of +/- 5% of specification, and absolutely zero power issues were experienced during testing.
As an added test, I moved this power supply to my other system with a DFI NF4 SLI-DR Expert motherboard. This motherboard is particularly picky on components and I did not have any issues with this power supply, everything ran flawlessly.
