2. Open the PC case also following the manufacturer's instructions.
3. Disconnect all plugs from the motherboard and all other components, such as an FDD, HDD or optical
drives. Ensure that there are no plugs from the old power supply connected to any of the components.
4. Now remove the screws on the rear of the power supply and take it out carefully. Make especially sure
that no cables get caught in the components and damage them.
Installing your new be quiet! Pure Power power supply:
1. Place the new power supply in the space provided in the case and screw it on the rear with the four
screws provided. Do not use excessive force.
2. Plug the 20/24 pin connector into the socket provided on the motherboard. If you have a 24 pin
connector, put the remaining 4 pins in the right position before plugging the connector into the socket.
If using a 20 pin connector, simply leave the additional 4 pins on the side.

Please note:
In ATX systems, the power supply receives a signal from the motherboard when switched on, without which
it cannot run. For this reason, please ensure that the power switch connector (usually located on the front
panel) is correctly connected to the motherboard using either the motherboard or case manual. If this is
the case, check the power (on/off) switch, as it may be faulty which means the power supply cannot be
started. You can use the reset switch instead of the power switch in order to avoid such faults.
Careful!
Working on power sources could lead to serious injury. You must read item 2 – „Warnings and safety
instructions" carefully. Repairs must only be carried out by authorised technicians!
