So, what's special about the Fusion 550R PSU? Well, according to Arctic Cooling switching to this PSU can save you 100€ over four years compared to a standard PSU (assuming it's in service 200 days/year with 4 half days at full load and where juice costs 0.15€/kWh - you'll have to number crunch your own kWh figures to find out how much you can save). A quick number crunch based on average kWh prices across the US suggests that over 4 years you'd save roughly the price of the unit.

Here's the spec of the PSU:

  • Ultra quiet  80mm PWM fan with low noise impeller
  • 550W maximum output power, ATX 2.2
  • 82-86% efficiency, 99% PFC
  • 80mm ARCTIC F8 Pro fan
  • Intelligent fan control (700 – 2,000 RPM)
  • Controller for case ventilation
  • Over-Power, Over-Voltage, Short Circuit protection
  • SLI and Crossfire compatible

The externally mounted fan is certainly an interesting idea - as long as it doesn't get fouled by anything and fry the PSU.

Personally I think that this might be worth considering if building a new PC or replacing an old PSU, but I wouldn't bother replacing an existing PSU for those savings. Much better to switch on power management or turn your PC off when it's not in use.
