C. Inspect the connection of the on and 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 ac-
tivating the on/off switch on the case. If the power supply doesn‘t allow itself to be turned on, continue with
the next point.
D. Check your system for possible short circuits or defective hardware in that you turn off your computer and
separate all of the devices from the system that are not required for starting your computer. Turn the com-
puter back on. Repeat this step and after each re-start, close 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.
Frequent problems:
Problem: The selected voltages (via BIOS) are to 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 dimension of the mainboard and
does not necessarily have to correspond to reality.
Problem: After installing a new graphics card, the PC can no longer be turned on or crashes with
practically every opportunity:
You have installed a new higher performance graphics card in your system and now your PC no longer starts
or it seems to crash immediately with the first workload. The power supply is too weakly dimensioned for your
graphics card. Before making a purchase, please take a look at our watt configurator at www.be-quiet.net. Here
you‘ll find the right be quiet! power supply from our assortment
