Product Usage Instructions
Installation and Accessories:
Before you begin with the installation, please read the section Warnings and safety notes. For the arrangement only use the supplied screws since these have the correct thread. You need a screwdriver for the correct arrangement.
The following parts are included within the delivery:
- Screws for the PSU assembly
- Power cord (Please only use the power cord which is included; low-quality cords can damage your PSU and your PC-system.)
- Brief instruction incl. Information about the warranty
Place the PSU into its designated place within the case and fix it with the supplied screws. First insert the plugs for the mainboard supply (20/24 pin, 4 pin and possibly the power cord provided in the package. Low quality power cord may damage the PSU and PC system! Turn on the PSU and then start your PC.
Safety Functions:
UVP (Undervoltage Protection): If the voltages fall below a certain tolerance value on the single lines, the PSU automatically switches off.
OVP (Overvoltage Protection): If the voltages increase above a certain tolerance value on the single lines, the PSU automatically switches off.
SCP (Short-circuit Protection): In the case of a short-circuit this feature prevents damage to the core components of the PSU and its system components.
OPP (Overload Protection): If the system is oversized and requires more power from the PSU than it can perform, this protection function is activated.
OCP (Overcurrent Protection): If the current on a single line is higher than indicated,the PSU automatically switches off.
Troubleshooting:
WARNING: Never work on the PSU yourself. Even long time after its deactivation, life-threatening voltages can still be present in the PSU. Repairs should only be made by authorized specialists.
If there is smoke, cable damage or intrusion of liquids, the PSU has to be immediately disconnected from the power network and must not to be put into operation anymore afterwards. Never open the PSU. It contains components, which can show high voltages even after long periods of deactivation. Again, repairs should only be done by authorized specialists.
FAQ
- Q: What should I do if my PSU overheats?
- A: If your PSU overheats, immediately turn off your PC and check for any obstructions to airflow around the PSU. Make sure all vents are clear and unobstructed to allow for proper cooling.
- Q: Can I use a different power cord with the PSU?

Introduction
Dear customer:
Thank you for choosing a COUGAR® power supply unit. Before the installation please read the manual below carefully. If you have any questions, please contact our customer service:
Warnings and safety notes
Never open the PSU cover. There is a potential danger of life due to high voltage inside. The PSU should only be opened by an authorized technician. The manufacture warranty will be void, if the PSU is opened by an unauthorized person. Do not work on the PSU or the PC as long as the main voltage is still connected. Switch the I/O button to position “0” and disconnect the power plug from the power network. Protect the PSU against moisture. The PSU is suitable for operation at 200-240V/50-60Hz. The ambient temperature should not exceed 50°. Please pay attention to the power de-rating on all models with a decrease of 1%/°C starting at an ambient temperature of 25°C. Please ensure that there is sufficient ventilation of the entire system.The leakage current must not exceed 3.5 mA. Make sure during the installation of the PSU that the ventilation slots are not covered. Do not clog the ventilation slots of the PSU. Keep your PC away from direct heat sources such as radiators. When using an extension cord and/or multiple sockets pay attention to the maximum through-connection ability in order to avoid short-circuits. If you want to clean your PSU, disconnect the power plug from the power network and remove it from the PC case. Before the removal make sure that you are not statically charged, (e.g. through carpets or wool sweaters).Only clean the PSU on the outside, always using dry cloth, never water or detergent. During the operation of the PSU pay attention to the maximum loads. The single loads and the total loads must not exceed to cross the values shown in output power table. Avoid the use of adapters, such as 4Pin Molex to 6+2Pin PCI-Express.

Troubleshooting
WARNING:
Never work on the PSU yourself. Even long time after its deactivation, life-
threatening voltages can still be present in the PSU. Repairs should only be
made by authorized specialists. Working at power sources can lead to life-
threatening injuries. If there is smoke, cable damage or intrusion of liquids
the PSU has to be immediately disconnected from the power network and must not
to be put into operation anymore afterwards. Never open the PSU. It contains
components, which can show high voltages even after long periods of
deactivation. Again, repairs should only be done by authorized specialists!
Problem: After the installation of the new PSU the system does not start.
Possible solutions:
- Check the power code and the power supply of the wall socket and/or multiple socket strip. Also check whether the multiple socket strip can supply the necessary power.
- Check all connections within the PC; maybe not all cables are correctly connected.
- Check the internal cable of the I/O-switch of the PC case to the mainboard.
- Check the components for possible short circuits or defects.
Please also check the other components for compatibility. Often mainboard chipsets are not compatible with all memory and/or graphics card solutions. Contact the manufacturer of the component to get more information. If your PSU still does not function even though you have checked sources of errors mentioned above, please get in touch with our customer service This product is not to be disposed of in the regular household waste and must be brought to a collection point for electrical and electronic devices for recycling. The symbol to the left refers to that and can be found on the product, in the manual or on the packaging. Materials can be recycled according to their description. With the reuse, the recycling or other forms of reutilization of old devices you make an important contribution to the protection of our environment. Please inquire the appropriate location of disposal from your local administration.
