The ripple values of the Silent Pro M2 720W are far less impressive, as they're the worst of all the PSUs in every load test. Its ripple values range from 61.2mV at 200W to 115.4mV at 700W, which is only just within the 120mV limit. If you're a frequent heavy user or are interested in overclocking, you'll likely want to avoid this PSU.

The ATX12V Guide allows up to 120mV (peak-to-peak) of AC ripple on the +12V line and 50mV on the +5V and +3.3V lines. Ripple on all the lines was excellent at all power levels, staying under 10mV at all power levels up to around 200W, and only exceeding 30mV momentarily at full load only. This is excellent.

Dont think the review above is right as techpowerup says high ripple at 12v as well
