Thermaltake GF1 SNOW 650W Power Supply Review

Ripple
The ripple results provided in our testing of the Thermaltake GF1 SNOW were, shall we say, more than a little weird. As you can see in the chart below, while the 5V rail remained incredibly low, the 12V and 3.3V were a little more, well, everywhere. – With a minimum score of 18.4 recorded, this is clearly hugely below the EU maximum allowance of 50. – It does, however, seem that the power output does have a pretty notable effect on how cleanly the rails operate.
Anything to be worried about here though? In a word, no!
| Load (%) | 3.3V Ripple | 5V Ripple | 12V Ripple |
| 20 | 3.2 | 2.4 | 6 |
| 40 | 3.8 | 3.4 | 18.4 |
| 60 | 4 | 3.8 | 17 |
| 80 | 13 | 5.2 | 18.4 |
| 100 | 5.2 | 5.4 | 16.8 |
