TROUBLESHOOTING

Please note:

 If you have an ATX system, the power supply is enabled by the 

motherboard in order to boot the PC� For this reason, please refer to the 

motherboard  or  case  manual  to  check  whether  the  on/off  switch  is  connected 

correctly�

Caution

:  There  is  a  risk  of  fatal  injury  when  working  on  power  sources.  If  you 

notice traces of smoke, damaged cables and exposure to liquids, immediately 

disconnect the power from the mains and do not use it again�

Never open the power supply case� High-voltage components in the interior of the 

power supply may still be live after a longer period of disuse�

Please have any and all necessary repairs conducted by an authorized expert!

Opening the device will void your warranty.

If the system in which you installed the power supply does not work properly, 

check for these possible sources of error first:

∙

Check that the mains cable to the power supply is correctly and firmly plugged 

into the power supply and the socket� Ideally, you should use a separate power 

socket for the computer power supply�

∙

Check whether all connectors are correctly plugged in, and make any necessary 

adjustments, such as in case of incorrect polarity�

∙

Check the connection between the on/off switch on the case to the motherboard. 

Refer to the motherboard manual if needed! Switch the power supply on by 

setting  the  switch  to  position  “I”  and  then  pressing  the  on/off  switch  on  the 

case� If the power supply still does not switch on, continue with the next item�

∙

Check your system for possible short circuits or faulty hardware, making sure 

that  you  switch  off  the  computer  and  disconnect  all  devices  not  required  for 

the computer to start� Switch the computer back on� Repeat this process and 

connect one device after each reboot, until you discover the fault� If the power 

supply does not react due to a short circuit, wait for at least 5 minutes before 

switching back on as the device is equipped with overload protection�

FREQUENT PROBLEMS

Problem: The selected voltages (via BIOS/UEFI) are to low/high

If you check the power supply voltages via the BIOS/UEFI on the motherboard or 

the operating system, note that they may be displayed incorrectly� This typically 

results from imprecise measurements by motherboard and does not necessarily 

imply a genuine problem�
