All voltages are well within the limit of the ATX specification. They are not exceptionally stable but sufficiently constant for everybody except the most demanding users (who will get a higher wattage model anyway).
The ripple voltage is about average with 21.0 mV peak to peak.
| Standard deviation 3.3V | 4.82 |

| Power Efficiency | 80.4% (377W:469W) |
For easier comparison between power supplies we put the (normalized) line regulation standard deviation into graphs.
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. So the smaller the standard deviation is, the better the line regulation.
