The Power supply is cooled by a 135x135x135 mm fan (Adda ADN512UB-A90). The impeller is a nice design, nine wide blades with small gaps between.

The XFX power supply is manufactured by Seasonic and it is a very clean internal design. This is a DC to DC Converter Design to provide enhanced Dynamic response while ensuring system stability and maximum 12VDC rail output.

There are several rows of heatsinks, seperating the components and ensuring adequate airflow from the large fan directly 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).

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

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.
