be quiet! Pure Power 11 700W [7/52] Troubleshooting

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/o 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 rst:

∙ Check that the mains cable to the power supply is correctly and rmly 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/o 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/o 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 o 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�
