Antec Neo HE User's Manual
ATX12V version 2.2 power supply
Models: Neo HE380, Neo HE430, Neo HE500, Neo HE550
Introduction
The Neo HE power supply series supports the newest ATX12V version 2.2/EPS12V 2.2
specifications. Neo HE has increased output power distribution to match the newest Intel and
AMD processor requirements. Furthermore, it includes three +12V outputs that deliver safer and
more reliable power to your system's components. Delivering up to 85% efficiency, this power
supply saves energy and money on your electrical bill compared to typical power supplies. Also,
Neo HE power supplies generate less heat because of the high efficiency which keeps the power
supply cooler and prolongs its working life. Also included are a variety of industrial-grade
protective circuitries: OCP (over current protection), OPP (over power protection), OVP
(over voltage protection), SCP (short circuit protection), and UVP (under voltage protection).
Special Quiet Computing Fan Operation
Neo HE power supplies feature an innovative design that decreases noise during normal use, but
which allows for superior cooling capabilities as loads increase. Owing to its ultra high efficiency
and low heat generation, Neo HE can utilize a smaller size exhaust fan that rotates slowly and
quietly to blow hot air out of the power supply, speeding up as heat increases.
Neo HE power supplies include Universal Input and Active Power Factor Correction (PFC).
Universal Input allows you to connect your Neo HE power supply to any AC power outlet
between 100~240V without having to worry about setting a voltage switch. Active PFC
improves the power factor value of the power supply by altering the input current wave shape,
helping the power plant provide power to users more efficiently.
Connectors: Neo HE power supplies are ATX12V version 2.2 form factor compatible. The
Neo HE380 and Neo HE430 include a 24-pin main power connector with detachable 4-pin
connector, and a 4-pin +12V power connector for ATX single CPU systems. Neo HE500 and
Neo HE550 include a 24-pin main power connector with detachable 4-pin connector, a 4+4 pin
+12V power connector for EPS12V dual CPUs and ATX12V single CPU systems with
detachable 4-pin connectors. In addition, all models include six 4-pin peripheral connectors, four
15-pin Serial ATA Connectors, and PCI Express Power Connectors (two for Neo HE500 and
Neo HE550, one for Neo HE380 and Neo HE430).
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 with the soft switch.
Advanced Cable Management System: Neo HE power supplies feature 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 cables (see Picture 1):
