Corsair RM750i: 80Plus Gold PSU that performs very well

The efficiency is fine, neatly in line with other 80Plus Gold power supplies. The ripple is incredibly low and the power supplies are inaudibly silent. Other advantages include an FDB fan, 10-year warranty and extensive monitoring through Corsair Link.
