Safety and Warnings
IMPORTANT INFORMATION ON
SAFETY AND PROPER OPERATION OF THE POWER SUPPLY.
<< Read the information carefully before using it. >>
1. Do not attempt to take apart the power supply. There are hazardous voltages inside.
2. Do not add or remove any components from the power supply. Warranty void by doing so.
3. Only authorized technician or service center is allowed to open the power supply for product
services.
4. Never alter the power supply cord or plug. Improper modification can result in severe electrical
shock.
5. Do not expose power supply to high moisture, very dusty or extreme temperature environment.
6. Connect power supply only to designated power sources. Do not place any other materials into
the inlet of the power supply other than the power cord.
7. Do not plug or unplug the power cord with wet hands.
8. To avoid power cord damage, remove the power cord from the wall outlet by grabbing the plug
instead of the cord.
9. Make sure the power cord is properly routed so that it will not be stepped on, tripped over, or
otherwise subjected to damage or stress.
10. To avoid electrical shock, unplug the unit from the power source before attempting any cleaning.
Note1: For safety purposes, power cord must comply with the requirements of the National Safety Code.
Note2: All relevant registered trademarks are strictly the property of their respective companies.
Note3: No further notice will be given for any revision of the product, either modification or a newer
version.

Product and Accessories
Please contact your local dealers if any of the following product or accessory is missing from the
package.
1. Power Supply Unit. (Refer to the Figure)
2. Screws x 4.
To prevent missing screws during shipment, screws were installed on the power
supply. When install power supply into computer, remove those four screws first,
please do not remove fan or case screws. All four screws should be installed and
fasten.
3. ATE (Auto Testing Equipment) report.
4. User manual.
5. Optional item – AC power cord.
Remark: All items listed above have been tested and approved; unauthorized accessories should
not be used on this product.
Note: The above figure is just a sample; please refer to the actual product.
Remark:
1. I/O switch on rear panel is only available for HG2 model.
2. The computer case shown above is not part of the power supply.
3. Screws and its specifications.

Specifications
Please refer to the specifications according to the actual product purchased.
Note: The new feature, “Prolonged Cooling” after power supply is remote-off only available on model
HG2. Under normal conditions, when power supply is at “Remote-off” mode, cooling fan will remain in
operation for the secondary heat dissipation, and will come to stop at a much lower temperature. This will
prolong the life of the power supply.

Operational Procedure
1. When removing four attached screws to install this product, please make sure not removing fan or
case screws by mistake.
2. Tighten four screws onto the computer case and double check for stability. (Please refer to the
figure on page 4).
3. Before connecting the units, make sure you verify connector and pin assignment for devices such
as motherboard, hard disk etc. For example, the pin assignments of 24-pin and 8-pin connector on
AMD Athlon MP Motherboard are totally different than Intel Xeon motherboard. Severe damages
may occur by wrong connection.
4. Check product specifications and calculate actual current requirements of each DC voltage. Make
sure these requirements fall within the minimum and maximum range of power supply. If the
current requirements are below the minimum load spec., the power supply may not start up. If the
current requirements are over the maximum load spec., our over protection circuitry will latch and
shutdown the power supply.
5. Plug in power cord to the inlet of power supply.
•Only HG2 models have line power I/O rocker switch. Please set the switch to “I” or “ON”
to turn on line power. For other models, just plug the power cord into the electrical outlet
directly.
•Active Power Factor Correction (PFC) function is available for all power supply models
listed in this manual. The PFC function ensures maximum efficiency of power usage to
preserve energy and lower your electrical bills. It also automatically adapts to a very wide
range of AC line voltage: 100V to 240V AC. (There are no manual switches for you to
select AC input). This unique design ensures you can use our power supplies anywhere in
the world.
6. You can start up the power supply remotely by using “Remote on”.

Troubleshooting & Maintenance
SYMPTOM COUNTERMEASURE
No power? After plug main connector, such as 24-pin or 20-
pin and aux. connectors
if needed, to motherboard socket, make sure AC power cord gets AC line
source that is on wall outlet, to this product
power supply. If AC power
cord gets AC line source through power bar or UPS, turn on these
devices first.
If product model is HG2, set I/O switch of power supply panel to “I”
or
“ON”. Other models HP2, PSM and PSL don’
t have line power I/O
rocker switch.
Boot system from computer case I/O.
Check product specifications and calculate
actual current requirements of
each DC voltage. Make sure these requirements fall within the minimum
and maximum range of power supply. (i) If the current requirements are
bel
ow the minimum load spec., the power supply may not start up.
Increase load. (ii) If the current requirements are over the maximum load
spec., our over protection circuitry will latch and shutdown the power
supply. Reduce load or use larger capacity power supply.
There may be a system incompatibility or
wrong connector pin out or
connection, when power supply its fan has spin for while then shutdown.
For example, (i) Use wrong pin assignments of 24-pin and 8-
pin
connectors e.g. For AMD Athlon MP Motherboard
connectors are totally
different than Intel Xeon motherboard. Severe damages may
occur by
plugging wrong connection. (ii) Plug wrong pin position on small 4-
pin
floppy drive connector to cause connection displacement.
[Action] Remove all connectors at all first, then one-by-one to
plug in
one connector at a time and
verify the operation of each device and
system function. When no problem, proceed next device.
The power supply could be latched by self-protection function (e.g.
“over
voltage”, “over current”, “overload”)
. Remove the power cord, wait for
20 seconds or more to discharge its electricity, then plug in the power
cord again, try to restart the computer.
Power is on, but no
monitor display?
Check if video card is seated properly; check the video cable connection.

Verify system and motherboard requirements. For example, some
motherboards require RAM in pairs to work properly
, such as Tyan
#S2665.
