Antec SP-500 SmartPower 2.0 User's Manual
SmartPower 2.0 series power supplies comply 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
consumption 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 circuit protection).
This power supply is also backwards-compatible with previous ATX form 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.
Special Quiet Computing Fan operation
SmartPower 2.0 features an innovative design to help decrease noise during normal use, but
which still allows for superior cooling capabilities as loads increase. To this end SmartPower 2.0
features both a thermally controlled 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
hot air out of the power supply and case, 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, at which
point it starts to function.
We've also included a 3-pin fan signal connector. Connect it to one of the fan connectors on
your motherboard. You can monitor the speed of the internal intake fan through your
motherboard BIOS or through the monitoring software included with your motherboard.
Note:
When temperatures are low, the speed of the fan may drop below 950RPM. At such low
speeds, some motherboards may not be able to properly detect the fan speed and may generate
false warning of fan failure. To ensure proper fan monitoring, please refer to your motherboard
manual.
Active Power Factor Correction
(applicable only to models designed for sale in the European Union)
SmartPower 2.0 models designed for the EU include Power Factor Correction (PFC) circuitry
in accordance with European standard regulation code EN61000-3-2.
Power Switch
This 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.
In normal operation there is no need to turn the switch to the OFF (O) position since the
power supply is equipped with a soft on/off feature which turns your computer on and off
through the soft switch on your computer case. You may need to turn the switch to the OFF
position occasionally should your computer crash and you cannot shut it down through use
of the soft switch.
Advanced Cable Management System
SP-500 features Antec's Advanced Cable Management System. It allows you to use only the
power cables that you need, thereby reducing clutter and improving airflow inside your case.
Inside the package, apart from a power cord, you will find the following (see Picture 1):
