Ripple
Noise and Ripple can easily be measured by an oscilloscope. These show how much voltage fluctuation there is on a particular rail. We tested the rail stability of the 3.3 volt, 5 volt and 12 volt rails using an identical time and millivolt scale for all graphs. millivolt ripple is measured by the peak to peak size of the voltage curve.
The latest ATX 12 volt version 2.3 specifications state that ripple from peak to peak must be no higher than 50 millivolts for the 3.3 volt and 5 volt rails, while the 12 volt rail is allowed up to 120 millivolts peak to peak to stay within specifications. Millivolt figures are stated to the closest increment of 5 given their variability.
| Load (%) | 3.3V Ripple | 5V Ripple | 12V Ripple |
| 20 | 15 | 15 | 20 |
| 40 | 15 | 15 | 20 |
| 60 | 15 | 15 | 25 |
| 80 | 20 | 20 | 30 |
| 100 | 20 | 25 | 35 |
I don’t think the fan profile is terribly important. If you have a muscle bound system that can come close to occasionally demanding the kind of power this unit can supply then the chances are you’d rather settle on 1400w+ PSU.
I’m surprised XFX didn’t opt for a San Ace fan which is something Seasonic does and is touted to be one of the best if not the best in the the consumer PSU game. Can it really make much difference the in price?

Its very bad power i have one 1250 pro but its very shit dont buy this shit
