Tested on: AMD Athlon64 FX-62 @ 2800 MHz, ABIT AT8, 2x 512 MB DDR400, WD Raptor 36 GB, Radeon X1900 XTX + Radeon X1900 XTX Crossfire
Both 5V and 12V show great stability, the 3.3V line seems to be a bit low and does fluctuate a bit but this is no problem at all, since you can adjust the output voltage in the P-Tuner software. These tests were ran with voltage outputs set to 12.00V, 5.00V, and 3.30V.
The ripple voltage was measured on the 12V line at idle. With an amplitude of 13 mV it's very good.
| Standard deviation 12V | 5.25 |
|---|---|
| Standard deviation 5V | 4.97 |
| Standard deviation 3.3V | 7.44 |
| Power Factor | 0.99 |
| Ripple Voltage 12V | 13.2 mV |
| Power Efficiency @ 320 W | 84% (320W:380W) |
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.
GIGABYTE did a great job engineering this PSU to be as efficient as possible. With over 84% it can claim the number one spot of our test group.
