Testing and Results:

Test System
Motherboard: Chaintech 9CJS
CPU: Intel Pentium 4 3.2 "C"
Memory: 2 x 512MB PC4000
Video Card: Radeon 9700 Pro
Hard Drives: Western Digital 80GB
OS: Windows XP Professional

For our testing procedure we take direct readings off the 20-pin ATX connector that goes to the motherboard. We find that using this method is the most accurate way to monitor the voltages coming directly off the power supply. For more information on why we test this way, please read this article. Two sets of readings are taken. One set is taken at idle, which we simulate by letting the computer sit at the desktop while not running any applications. The other set of readings are taken at full load, which is simulated by running Folding @ Home. We monitor the voltages and check for fluctuations as well.

Test Results
  +3.3V +5V +12V

Idle:

 3.39V - 3.40V 5.12V 11.93V

Load:

 3.39V - 3.40V 5.12V - 5.14V 11.86V - 11.93V

Results show this power supply to be within specified ranges and very solid voltage levels. These voltages were straight out of the box, remember there is a potentiometer for some of the more hardcore overclockers that want to fine-tune their rails.
