Arctic Cooling is possibly more popular for its cpu/vga coolers, but the peripheral manufacturer recently decided to enter the market of power supply units for PCs, with the release of the Fusion 550R PSU. The company claims that the device is among the less noisy PSUs available today while its ATX design make it compatible with any ATX PC case. The PSU offers a continuous power of 550 Watt, enough to cover the needs of PC gaming systems. In addition, the available 6-pin- and 8-pin PCIe connectors can be used to power 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 safe 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.
