Features & Specifications:

There isn't really of lot of logos and other certification on the box or on the PSU itself in regards to what it can handle.  Arctic Cooling hasn't applied for SLI or Crossfire certification even though this unit comes with four PCIe connectors and seems to handle a pretty heavy load just fine.  Even though a "certified" PSU is said to be good, they can still fail, so don't put all of your money on the "certified" sticker on the box.  Arctic Cooling does say that it is Crossfire and SLI compatible though.  With that in mind, let's see what else they say about this unit.


Fusion Specs Fusion 550R follows the default ATX-Form-Factor and thus will fit into every ATX PC-Case. It fulfills the ATX 2.2 specifications and can offer a continuous power of 550 Watt - enough for every High-end System. Equipped with two 6-pin- and 8-pin PCIe connectors the PSU is ideal for powering a Crossfire- or SLi-setup.

Main features

  • Ultra quiet  80mm PWM fan with low noise impeller
  • 550W 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, Over-Current Protection
  • SLI and Crossfire compatible


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. Additionally to this the PSU comes along with two external fan-connectors giving the possibility to control the case ventilation based o­n load and temperature and thus lowers the noise level of the complete system to an absolute minimum.

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

Save and stable PSU
With a PFC-factor of 99 % and two separated 12-volt-rails, which are supporting each other if necessary the Arctic Fusion 550R is a very save PSU, that manages to come along with highest demands. The overload, overvoltage and short-circuit protection safeguards the hardware as well as the user from damage.

 

While Arctic Cooling rates this PSU as 550W, if you look at the label above and do a little math you can see that they didn't leave a lot of room.  According to the documentation, they nailed the math and their rating.  Hopefully they underrated the rails at 17A or we could have some stability issues later on.
