6. 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�
7. 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�
