Fan: - 80mm ARCTIC F8 Pro
Fan Speed: - 700 - 2,000 RPM by Intelligent Controller
Noise Level: - 0.08 - 0.3 sone
Power Good Signal: - 100 - 500 mS
Hold Up Time: - >17 mS
MTBF: - 100,000 hours at 25˘XC ambient temperature

High Efficiency = Less Power Loss = Quiet Cooling, With an efficiency of at least 82 to 86%, less heat is generated inside the PSU. As a result of this a single 80-mm-fan is enough to cool the PSU. The rubber-mounted fan is spinning in a range between 700 and 2000 RPM making it virtually silent.
Effective energy-use preserves nature and saves money.
By making appreciated use of natural resources, especially energy you can contribute to lower CO2-Emissions. Additionally you save electricity cost of about 100 €, so the Fusion 550R is a true Payment Saving Unit*.
* In 4 years, 200 d/y with 4 h/d full load at 0,15€/kWh
It seems Arctic Cooling really are pushing this as a power saving unit, and with an efficiency of 82%-86% and power factor correction of 99% its right up there with the best of the rest. It has all the features one would expect of a good power supply, over voltage, over current protection, over power protection and short circuit protection. Arctic Cooling quote noise levels in sone rather than dB, as 0.3 sone is roughly 22dBa it should be fairly quiet even with the fan running flat out.
I would have liked to see some power ratings for the various power rails list under the specifications, as this is what most users would probably be interested in. This is only available in the downloadable manual. The two extra fan connectors are a nice inclusion as not all motherboards allow all case fans to be controlled. Also it should last a decent time too with a MTBF of 100,000 hours. What is interesting is the fact it is a 500w PSU and the 550R is peak which it could probably only maintain for about 2 secounds..
