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

I really liked that I could set 2 fans on it and have them slowed down. However for some reason a 140mm fan (Scythe Kaze) I had on the side pannel which require only 0.04A to work wouldn't get powered at all, while the 2 intake (Scythe Slip Stream 1200rpm) which require 0.26A worked flawlessly and even better since the PSU's fan wire work up to 0.15A so it slowed them down just enough so they get totaly quiet instead of very noisy. So other than the 4Pin very annoying issue, it's a great psu.
Im using this to power an Overclocked Radeon 4850, and an AMD 6000+, with 4 GB of 2v RAM. It is all very well powered, and the voltages delivered to all the components are well within specification, buuuuut, my one major complaint is the cable management. if you have a sata CD ROM and a Sata hard drive with a 21" case like I do.... Good luck.... Luckily my CDroms are ATA. Otherwise this thing is just perfect!
Well, seeing that I am the first to review I will do my best to add as much detail as I can.
Firstly what really liked about the PSU is the design and power consumption. For someone who has their PC on 24/7 with in an Antec 900 and all those fans, it's a dream come true for the hydro bill.
