These specs looks very impressive. Four independent 12V rails means there will be juice for even the most power hungry systems available.
Tested on: AMD Athlon64 3000+ @ 2000 MHz, ABIT AT8, Radeon X1900 XTX + Radeon X1900 XTX Crossfire, 2x 512 MB DDR400, WD Raptor 36 GB.
In our load test we see that all voltages are quite stable and very close to their optimum values.
Above image shows the Ripple Voltage measurement (5 mV per vertical division, 5uS per horizontal division). 15mV 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.
