Great specs. With four independant 12V rails there should be enough power even for the most demanding systems that you could build.
Tested on: AMD Athlon64 3000+ @ 2000 MHz, ABIT AT8, Radeon X1900 XTX + Radeon X1900 XTX Crossfire, 2x 512 MB DDR400, WD Raptor 36 GB.
The load test shows that all voltages are ok. The high 12V line might be interesting for hardcore overclockers, because there is more voltage drop headroom. On the other hand, if you consider variations in manufacturing, either our PSU has an already high 12V line or there may be units which could break the specifications of 12.60V max.
Above image shows the Ripple Voltage measurement (5 mV per vertical division, 5uS per horizontal division). 14mV from peak to bottom is an average result. Ripple Voltage was measured at idle.

Standard deviation is a statistical term, which tells how far away from the average the measurements are. In other words it's the average of the average.
A large standard deviation indicates that the data points are far from the average and a small standard deviation indicates that they are close within the average.
