Very quiet and excellently finished PSU. I have it in the ground installation of Aerocool DS housing and had no problems - neither with the installation, even with the wiring of all devices / motherboard / hard drive / burner / fan. Compared to another identical Be Quiet PSU (without the Listan name), it is here at the Listan PSU not possible to insert cables separately or to leave out - which I think would be eh unnecessary anyway because almost all cables are required. Each harness is entwined with a fishnet, excellent verabeitet and long enough in order to move the way I want it. Strong buy recommendation, this power supply I would buy again at any time
