Safety Functions; Troubleshooting - BE QUIET! DARK POWER PRO 10 Mode D'emploi

7. SAFETY FUNCTIONS

All be quiet! power supplies have numerous safety functions. They are designed to protect the power
supply and the components connected to it against damage. If one of these safeguards is triggered, the
system will reboot or power off in most cases.
If this happens, you should immediately check the PC for errors.
For more info on troubleshooting see the "Troubleshooting" chapter.
The DARK POWER PRO 10 Series has the following safety functions:
OCP (Over current protection)
If the load on the individual circuits exceeds the specified limit, the power supply is automatically
switched off.
UVP (Undervoltage protection)
This safeguard is triggered if the voltage on the circuits drops below a certain limit.
The power supply is automatically switched off in this case.
OVP (Overvoltage protection)
The overvoltage safeguard is triggered if the voltage in the circuits is too high; the power supply is
deactivated.
SCP (Short circuit safeguard)
The fuse protecting the power supply's secondary circuits prevents physical defects of the power
supply and the components connected to it.
OTP (Temperature safeguard)
In the case of excessive heat build-up in the power supply, the power supply immediately and
automatically switches off.
You cannot switch it back on until it has cooled down. Please ensure that the PC has sufficient cooling.
OPP (overload protection)
This safeguard is triggered if the total output of the power supply exceeds the specified maximum load.
This can happen if the output of power supply is insufficient for the system (incorrectly dimensioned).

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
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.
