8. 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

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.
