Troubleshooting; Frequent Problems - BE QUIET! STRAIGHT POWER E9 Mode D'emploi

OTP (Temperature safeguard)
If the temperature within the power supply rises to a level where the hardware might be damaged the
power supply will automatically turn off. When the temperature falls the power supply can be used
again. Always make sure that your system receives enough cooling.
OPP (Over power protection)
This safeguard is triggered when the entire performance demanded of the power supply is higher than
the specified peak load. This can happen if the power supply doesn't have enough capacity left.

7. TROUBLESHOOTING

Please observe!
In ATX systems, the power supply receives the signal from the connected mainboard in order to be
started up. For this reason, please check whether – with the help of the mainboard or the case manual
– the activation/deactivation is connected correctly.
Attention: Work with electrical sources can lead to life-threatening injuries. In case of trails of smoke,
damaged cables and the effects of fluids, the power supply is to be immediately unplugged from its
source of electricity and after that, no longer brought into operation.
Never unscrew the power supply. The are components in the interior that can contain high amounts
of voltage when not used for a long period of time. Please have any and all necessary repairs be
conducted by an authorized expert!
If the system for an installed power supply does not function properly, you must first check for
these possible sources of error:
A. Make sure the electrical cable is plugged into both the socket and the power supply correctly and
tightly. Ideally, you use a separate power socket only for the computer power supply.
B. Check to make sure that all connections are correctly connected to each other and correct them if
necessary, for example, in the case of wrong polarity.
C. I nspect the connection of the on/off switch from the case to the mainboard. If necessary, consult
your mainboard instruction manual! Switch on the power supply by placing the switch on position
„I" and activating the on/off switch on the case. If the power supply doesn't turn on, continue with
the next point.
D. C heck your system for possible short circuits or defective hardware by turning off your computer
and separate all of the devices from the system that are not required for starting your computer. Turn
the computer back on. Repeat this step and after each re-start, re-connect one of the devices until
you have found the supposed defect. If the power supply does not react due to a short circuit, wait
at least 5 minutes until you re-start your computer because the device is equipped with overload
protection.

8. FREQUENT PROBLEMS

Problem: The selected voltages (via BIOS) are low/high
When you check the voltage of the power supply in the BIOS of the mainboard or in the operating
system, it is possible that these are displayed incorrectly. This results from the non-precise mesuring
of the mainboard and does not necessarily have to correspond to reality.
