1. Function Description
This power supply is designed for personal computer. There are eight DC
outputs:+5V,+12V1,+12V2,+12V3,+12V4,-12V,+3.3V&+5VSB and it provides
power to all computer systems and peripherals with maximum protection.
Here are some of the key features:
It is rather simple to install this power supply to your precious computer
tower. Follow the steps below to finish the setup.
Step1:Open the computer tower cover; put the power supply into the
corresponding location of the tower, and then use right screws to fix the
power supply to tower.
Step2:Put the Main Power Connector, ATX12V Connector, S-ATA Connector,
dual PCI express power connector, Peripheral Connectors and Floppy
Connectors to the corresponding male connectors of main-board,
peripheral devices(i.e. HDD, CDROM etc.) and floppy drivers
respectively. When you connect connectors, please pay attention to the
orientation of them because of the different hole sizes. Find the proper
orientation and push down firmly making sure that the pins are aligned.

3.4 Protection
The power supply itself is designed with short circuit, over voltage, over power
and over current protection functions described as below:
3.4.1 Short Circuit Protection
A short circuit on any DC output will cause the power to latch. The power
supply will withstand a continuous short circuit to the output without damage
or overseers to the unit. The +5V can be shorted indefinitely and will recover

3.2 Active Power Factor Correction
Active power factor correction (the advance technology most used in high power
SMPS) used a per-regulator before the main PWM convert circuit, applied the
current feedback technology. Regulated current drawing flow AC sinusoidal wave.
Therefore, the THD less than 5 percent,and the power factor increase to 0.99 or higher.
This method of PFC knows as Active Power Factor Correction because applied active
components and circuit inside. It can provide high power factor(up to 0.95-1),can
operate in world wide input range(100-240VAC).An intelligent solution for high regulation,
high power density power designs.
3.4.2 Over Voltage Protection
The power supply over voltage protection shall be locally sensed. The power
supply shall shutdown and latch off after an over voltage condition occurs. This
latch shall be cleared by toggling the PSON # signal or by an AC power

3.4.3 Over Current Protection
The power supply shall have current limit to prevent the +3.3V,+5V,and +12V
outputs from exceeding the values shown in below enclosed table. If the current
limits are exceed the power supply shall shutdown and latch off. The latch will
be cleared by toggling the PSON# signal or by an AC power interruption. The
power supply shall not be damaged from repeated power cycling in this
condition.-12Vand 5VSB shall be protected under over current or shorted
conditions so that no damage can occur to the power supply. All outputs shall be
protected so that on damage occurs to the power supply under shorted output
condition.

3.4.4 240VA Protection
System designs may require user access to energized areas of the system. In
these cases the power supply may be required to meet regulatory 240VA energy
limits for any power rail. Since the +12V rail combined power exceeds 240VA it
must be divided into separate channels +12V rails do not necessarily need to be
independently regulated outputs. They can share a common power conversion
stage. The +12V rail is split into four rails. Refer to section 6.4 for how the 12V
rail is split between different output connectors.

3.4.5 Over Power Protection
When the total load exceed 110%~160% of the maximum output current, the
power supply shall be latched into the state of shutdown.
Operation Conditions
The power supply shall be capable of continuous operation and meet all
electrical specification without need for adjustment when subjected to the
following environmental conditions:

5. Simple Maintainance
If power supply cannot work properly, before send for repair, please check the
following items:
5.1 Does power cord indeed plug into electrical outlet?
5.2 Does Input Voltage set in power supply correspond to the main source in your
environment?
5.3 Please check the output connectors plugging in proper direction and connecting
firmly.
5.4 Please turn off the power and turn it on for several times, and the interval must
be at least 5 minutes.
5.5 Having checked above items, if the power supply still does not function, please
send it back to your retailer or distributor for repair.
