Arctic Cooling Fusion 550R 500W PSU

It's not Power Supply Unit, it's Payment Saving Unit!
Fusion 550R follows the default ATX-Form-Factor and therefore will fit into every ATX PC-Case. It fulfils the ATX 2.2 specifications and can offer a continuous power of 550 Watt. Equipped with two 6-pin- and 8-pin PCI-E connectors the PSU is ideal for powering a Crossfire or SLI setup.

Features
1. Ultra quiet 80mm PWM fan with low noise impeller
2. 550W output power, ATX 2.2
3. 82-86% efficiency, 99% PFC
4. 80mm ARCTIC F8 Pro fan
5. Intelligent fan control (700 - 2,000 RPM)
6. Controller for case ventilation
7. Over-Power, Over-Voltage, Short Circuit protection, Over-Current Protection
8. 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 and as a result a single 80mm fan is enough to cool the PSU. The rubber-mounted fan rotates between 700 and 2000 RPM making it virtually silent. Additionally to this the PSU comes with two external fan-connectors giving the possibility to control the case fans based on the PSU load and temperature which lowers the noise level of the system to an absolute minimum.

Safe and stable PSU
With a PFC-factor of 99% and two separated 12-volt-rails (which support each other if necessary) the Arctic Fusion 550R is a very safe PSU. The overload, overvoltage and short-circuit protection safeguards the hardware as well as the user from damage.
