Antec TruePower 2.0 User's Manual
ATX12V version 2.0 power supply
Models: TPII-380, TPII-430, TPII-480, TPII-550, TPII-480Blue, TrueControl II-550
TruePower 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), UVP (Under Voltage Protection), and SCP (Short Circuit Protection).
Connectors: TruePower 2.0 is an ATX12V version 2.0 form factor power supply. It has a
24-and-20-pin Main Power Connector (pic 1, pic 2), a 4-pin +12V Power Connector, five 4-pin
Peripheral Connectors, four 15-pin Serial ATA Connectors, and one 6-pin PCI-Express
power connector.
This power supply is 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 TruePower 2.0 to any of your devices.
TruePower 2.0 includes an advanced temperature response system that provides optimum
balance between noise reduction and cooling. The power supply fan will always run at the
lowest speed possible for existing load and conditions. Furthermore, it can also control the
speed of your system case fans. You will find two dedicated fan connectors (marked "Fan
Only") to which you can connect your system case fans. TruePower 2.0 will then regulate your
case fans, further reducing system noise. Note: please don't connect more than three external
fans to the "Fan Only" connectors. If you need more cooling power than that, you can connect
your case fans to the regular 4-pin peripheral connectors, but that setup won't be as quiet as our
recommended setup. Note: Antec does NOT recommend connecting a CPU fan to the "Fan
Only" connectors.
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 rear power supply fan through your
motherboard BIOS or through the monitoring software included with your motherboard.
Note: When temperatures are low, the speed of the fan many drop below 1000 RPM. At such
low speeds, some motherboards may not be able to properly detect the fan speed and may
generate a false fan failure warning. 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): TruePower 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
