To test the voltages on this power supply, I measured each Molex, SATA and mainboard voltage at idle with my Craftsman Digital Multimeter and computed their average. Next, I measured these voltages at a system load. The load scenario was created by running Folding@Home on each core of the processor, defragmenting the main harddrive, playing music from the secondary harddrive in iTunes, reading a CD in Windows Media Player, using AIM and Firefox, and finally running the 3D view from ATi Tool. This stressed every component of the computer thoroughly.


On the front of performance, this power supply is, without question, solid and reliable. The fluctuation on the 12V line is slight and acceptable. Elsewhere, there's hardly any movement. Though this PSU is not “SLi Certified” or “Crossfire Certified,” I'm confident I could throw another card in there with no drawback whatsoever.

This power supply could, however, pose some problems in practical usage. The unit is light and small in length and the cables are all sleeved nicely, which helps with air flow and aesthetics. The cables are, however, slightly lacking. I used every single cord at least once in this setup, and I can easily see another case fan, CD drive, and hard drive causing issues. Further, the cables are quite short. I had some trouble routing the CPU cable around my heatsink, and the hard drive cables barely reached through the hard drive cage, such that I could not use the first connector on the cord. If you are going to be doing serious cable management, have a full tower case, or have a bottom-mount power supply, expect to have to buy some cable extenders. Also, if you are planning to run a card (or two) that requires an 8pin PCI-e connector, you'll have to buy some adapters for that as well.

The fan on this power supply is very quiet. Though it is slightly louder than my previous PSU with two low-RPM 80mm fans, it is still hardly noticeable in its sound. Nevertheless, it moves some serious air. I have never experienced a power supply that had such a full volume of air exiting the back of the unit.

The final major feature of this power supply is its price. Right now, it rings up at $94.99. This is about $25 less than average for a 600W power supply these days. When it all boils down, whether this power supply is right for you depends on how important certain things are. That is to say, if you want modular cables, long cables, and lots of options, and are willing to pay the price, this isn't the power supply for you. However, if you're on a budget and you don't want anything extra, seriously consider this PSU.

Thanks for reading and thanks to OCZ for supplying this review sample.
