Thermaltake Smart BX1 RGB 650w Power Supply Review

Ripple
If this power supply does have a fault in terms of the output testing, it lies in the ripple results. Specifically the 12V ripple. As you can see in the table and charts below, for 3.3V and 5V this power supply gives some fantastically solid results. When it gets to the 12V, however, the numbers start getting high.
A result of 48.8 is certainly quite high at 100% load. While this is within the acceptable levels by EU standards, it is skirting close to the edge. It, therefore, seems that while the power efficiency might be good, the 12V delivery is a little high on the ripple scale. We should again highlight though that all results are within the acceptable limits and this is not a fail.
| Load (%) | 3.3V Ripple | 5V Ripple | 12V Ripple |
| 20 | 9.2 | 8.6 | 24.2 |
| 40 | 11.4 | 9.8 | 29.6 |
| 60 | 13.8 | 9.8 | 35.6 |
| 80 | 16 | 10.4 | 43.8 |
| 100 | 19.6 | 10.6 | 48.8 |
