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.

Problem: After installing a new graphics card, the PC will not power on, or it crashes frequently.

SAFETY INSTRUCTIONS

The power supply is only guaranteed to function properly if the instructions are followed.

Only use original be quiet! power cables. Check the compatibility on bequiet.com if you use be quiet! power cables not supplied with this power supply. Using not be quiet! power cables or cables of older power supply unit series may lead to defects!
Connect the power supply directly with a power source. Don't use a outlet power strip.
Never open the power supply case. There is a risk of fatal injury when working on power sources. The electronic components inside the case generate a high voltage that is dangerous to humans. Even after disconnecting the power supply from a power source, some parts still have high voltages.
If you notice traces of smoke, damaged cables and exposure to liquids, immediately disconnect the power from the power source and do not use it again.
Please have any and all necessary repairs conducted by an authorized expert!
Opening the device voids your warranty.

• Never handle the power supply with wet or damp hands when in operation.
• Never insert objects into the power supply's apertures/fans.
• Note that the power supply is designed for use indoors in conditions without high levels of moisture in the ambient air. Using the power supply outdoors will lead to serious damage.
• Never work on the power supply while it is connected to a power source. In this case, always set the power switch to "O" and / or disconnect the power plug.
• In the event of a short circuit in the device, unplug the AC cable and do not use the device.

Make sure that your PC is not located directly next to a heating system or any other source of heat.
Make sure that your computer case is sufficiently ventilated by means of additional fans; with today's complex and powerful systems a power supply is incapable of dissipating the heat produced in the PC case without additional support.
Before using the power supply, allow it to warm up to room temperature for one hour to prevent condensation accumulating in the power supply.
