Antec TruePower ATX12V power supply
Models: TRUE330, TRUE380, TRUE430, TRUE480, TRUE550
Antec Low Noise Technology: The Antec TruePower power supply is equipped with
special circuitry to achieve optimum balance between noise reduction and necessary cooling.
Thanks to an advanced temperature response system the power supply fans run at the lowest
speed appropriate to load and conditions. The result is a great reduction in overall noise,
even in comparison to traditional thermally-controlled fans.
Your TruePower power supply can also monitor and control the system case fan speed.
There are two dedicated fan connectors marked Fan Only from the power supply for system
case fans. You may connect your case fans to them and have the TruePower circuitry
control the speed of the case fans.
Note: Please do not connect more than three external fans to the Fan Only connectors in
any combination. For maximum cooling you may choose to connect the case fans to the
regular 4-pin peripheral connectors, but in this fashion noise will not be reduced.
Connectors: The Antec TruePower power supply is an ATX12V form factor power
supply. An ATX12V power supply has a single 20-pin Main Power Connector, a 6-pin
AUX Power Connector and a 4-pin +12V Power Connector to the motherboard. It also
comes with seven 4-pin Peripheral Power Connectors and two 4-pin Floppy Drive Power
Connectors to your drives. It is backwards compatible to previous ATX form factor power
supplys. If your motherboard does not support the AUX Power Connector or the +12V
Power Connector, you can still use this power supply.
The TruePower power supply is also equipped with a 3-pin fan signal connector. Connect
it to one of the fan connectors on your motherboard. You may monitor the speed of the rear
power supply fan through your motherboard BIOS or through the monitoring software that
comes with your motherboard.
[Applicable only to models designed for sale in the European Union: TruePower
models designed for the EU include Power Factor Correction (PFC) circuitry in accord
with European standard regulation code EN61000-3-2. By altering the input current wave
shape, PFC improves the power factor of the power supply and results in increased energy
efficiency, reduced heat loss, prolonged life for power distribution and consumption
equipment, and improved output voltage stability.]
Installation:
Note (not applicable to models designed for the European Union): Check the red
power supply voltage switch setting before installation. It should be the same as your local
power voltage (115V for North America, Japan, etc. and 230V for Europe and many other
countries). Change the voltage setting if necessary. Failure to take this precaution could
result in damage to your equipment and could void your warranty.

Disconnect the power cord from your old power supply.
Follow your computer case manual and open the case.
Disconnect all the power Connectors from the motherboard and from the peripheral
devices such as case fans, hard drives, floppy drives, etc.
Remove the existing power supply from your computer case and replace it with
the Antec power supply.
Connect the Power Connectors to your motherboard and peripheral devices.
Connect the case fans to the dedicated fan connectors.
Note: Do not connect other devices except fans to these connectors. You may
connect case fans to the regular 4-pin Peripheral connectors if you choose not to
utilize TruePower Circuitry on your case fans.
Connect the 3-pin fan signal connector to one of the fan connectors on your
motherboard.
Note: You do not need to connect the 3-pin fan signal connector in order to make
the power supply work if you choose not to monitor the speed of the fan.
Close the computer case.
Connect the power cord to the Antec power supply
Note: The speed of the fan may be as low as 1500 RPM when temperatures are low. At
these speeds some motherboards may not be able to properly detect the fan speed and may
generate false warnings of fan failure. Please refer to your motherboard manual for proper
fan monitoring set up.
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.

3.0 PROTECTION:
If the power supply latches into shutdown stage (when over current, over voltage or
short circuit protection is working), the power supply shall return to normal operation
only after the fault has been removed and PS-ON is reset for a minimum of 1 Second
or remove AC power is removed and re-applied.
3.1 OVER CURRENT PROTECTION
Overload currents applied to each tested output rail will cause output trip before they
reach or exceed 110% ~ 150% for testing purposes. Overload currents should be ramped
at a minimum rate of 10 A/s starting from full load.
