The third chapter in the Quiet Computing™ story written by Antec—it’s everything you’ve come to expect from the prestigious Sonata line with even more upgrades and improvements. The Sonata III is whisper quiet when it comes to system noise while with the new High Definition front audio ports the sound you want your system to make will be crystal clear. And the front eSATA connector allows for simple data transfer. It’s all powered by EarthWatts 500 Watt power supply unit (PSU) which is equipped with universal input and Active PFC. This PSU is also 80PLUS® certified making it one of the most efficient PSU’s available. And all that means the Sonata III is the perfect combination of style, silence and efficiency.
