In the following figure System Power 7 PSU acts possibly a bit cheap by the photo. But this is not so, on the contrary! Clean processing and good quality. After installation and first start I heard absolutely nothing and got it with the fear to do. After loosening the side wall, I realized reassured that ran all the fans. Strange but true! The flexible and narrow harnesses were found to be very flexible, as the shell is very thin. I could almost all connections on the housing lay along, so that the airflow is not obstructed.
Not only for finished systems, I can recommend this power supply without restrictions. You will be surprised and it spares your ears and nerves.
