At Antec, we continually refine and improve our products to ensure the highest quality. So it's
possible that your new case may differ slightly from the descriptions in this manual. This isn't
a problem; it's simply an improvement. As of the date of publication, all features, descriptions,
and illustrations in this manual are correct.
SONATA II USER'S MANUAL
This case is designed to meet Intel's Thermally Advantaged Chassis (TAC) design guide
requirements. It comes with a unique Antec Chassis Air Guide (ACAG) to help cool high
performance CPUs.
It comes with an Antec SmartPower 2.0 series power supply with the newest ATX12V version 2.0
specifications. This includes dual 12V output circuitry that delivers safer and more reliable output
to your system's components, as well as higher energy efficiency, which reduces power consum
ption by up to 25% saving you money on your electricity bill. In addition we've included a variety
of industrial-grade protective circuitry: OCP (over current protection), OPP (over power
protection), OVP (over voltage protection), UVP (under voltage protection), and SCP (short cir-
cuit protection).
THE PUSH-PULL FAN QUIET POWER SUPPLY
SmartPower 2.0 features an innovative design to help decrease noise during normal use, but which
still allows for superior cooling capabilities as load increases. To this end SmartPower 2.0 features
both an internal intake fan as well as a unique external exhaust fan. The internal intake fan
operates when the power supply is turned on. It rotates slowly to blow out the hot air from the
power supply, and is thermally controlled, speeding up as heat increases. The external exhaust fan
remains off to make sure your computer maintains a quiet computing environment until the power
supply senses the required temperature to turn on the external exhaust fan.
This power supply is backwards compatible with previous ATX foam factor power supplies. To
make sure you connect your power supply properly, please refer to the user manuals supplied with
your motherboard and peripherals before connecting any of them to the power supply.
The power supply comes with a main power switch. Make sure you turn the switch to the ON
( I ) position before you boot up your computer for the first time.
Applies only to models designed for sale in the European Union:
SmartPower 2.0 series power supply models designed for the EU includes Power Factor
Correction (PFC) circuitry in accordance with European standard regulation code EN61000-3-2.
By altering the input current wave shape, PFC improves the power factor of the power supply.
This results in increased energy efficiency, reduced heat loss, prolonged life for power distribution
and consumption equipment, and improved output voltage stability.
SETTING UP
1. Place the case upright on a flat, stable surface. The power supply fan should be at the back,
facing you.
2. Note (not applicable to models designed for the European Union): Before installation, check
