Enermax ECO 80+ 620W Power Supply Review - Cases and Cooling 37

The Enermax ECO 80+ 620W power supply features a black matte finish with a gold colored fan guard.  The enclosure is only 140mm (5.5”) deep so it should fit in most any case and uses a single 120mm fan for cooling.

The backside panel features an open grill and includes a power receptacle and master On-Off switch.  The honey comb grill allows air to exhaust out of the power supply for cooling the internal components.

The bottom fan opening is contoured around the edge to help guide airflow into the fan and reduce turbulence (less noise).  This is the patented AirGuard aerodynamic design feature.  The fan speed is automatically controlled by the internal component temperature (speeds up as the combined load and temperature increases) via an onboard fuzzy-logic controller.
