At Antec, we continually refine and improve our products to ensure the highest

manual are correct.

Aria – MicroATX Cube Case
Your new case includes a preinstalled 300 Watt AR300 power supply, with
Universal Input and Active PFC (power factor correction). The AR300 includes a
quiet, low-speed 120mm fan that exhausts heat from the case.
The Universal Input feature allows you to connect the power supply to any
standard power circuit between 90VAC and 265VAC, without having to worry
about setting a voltage switch. The Active PFC feature improves the power
factor of the power supply by altering the input current wave shape. This
results in increased energy efficiency, reduced heat loss, prolonged life for
power distribution and consumption equipment, and improved output voltage
stability. Note: AR300's active PFC circuitry complies with European standard
regulation code EN61000-3-2.
Setting Up
1. Place the case upright on a flat, stable surface. The power supply fan
should be at the back, facing you.
