Anticipation about the device: Top! Keeps my system (FX8240, 8GB RAM, HD6870, 2SATA-HDs, 3 fan, opt. Drive) under tension and is almost not heard (for new games, such as BF3 is to hear something). He mounted smart and fast. In addition, everything is as described. Only one thing is not in the manual and the instructions: It runs only when consumers are connected. I'm desperate at first, because I thought he got broken. Prime was connected above all everything went as desired. Apparently a protective mechanism. If mans knows no problem. Somewhere Write it would also be a help ... Otherwise strong buy recommendation!
