A Closer Look

The Power+ 650W power supply is part of Akasa’s Perfomance Series line.  The enclosure is painted satin black and uses two Sanyo Denki SanCooler80 ball bearing fans for cooling.  The intake fan is mounted in a small housing on front of the power supply and blows air in while the second 80mm fan is mounted inside the back panel and exhausts warm air out.

The speed of the two fans is automatically controlled by the internal component temperature (they speed up as the combined load and temperature increases).  This type of push-pull configuration can provide excellent airflow and cooling.
