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 be quiet! Straight Power 12 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)
