XFX Pro Series 450w and 550w Power Supply Review

The 7 blade 120mm fan is a ADDA AD1212MB-A70GL ball bearing unit which is rated at .33A, 2050 rpm while generating 38dBa of noise and pushing 80.5cfm of air. The 650w, 750w and 850w models in this series use a 9 blade 135mm ADDA ADN512UB-A90 unit.

XFX use high quality Japanese capacitors which are rated to withstand up to 105c. These are conductive Polymer Aluminum Solid Electrolytic Capacitors to help improve operational stability under continued load conditions.

There are also several rows of heatsinks seperating the components which receive air flow from the fan above.  The XFX PSU is supplied with automatic output protection to ensure no damage occurs. This includes Total Power Protection (OPP), Over Voltage Protection (OVP), Over Current Protection (OCP), Short Circuit Protection (SCP) and Over Temperature Protection (OTP).  The cables are sleeved well into the chassis, which helps to ensure no long term damage by fraying. The cabling is well routed and organised with ties.
