The first power supply shipped showed no reactions, and went Worldvide Back. A fast supplied Power supply worked well at first. After a few days and a longer work on the PC, it crackled, the PC was made and lost his job. So we went a few times, was then being mostly off shortly after you start Windows. The power supply makes a very good first impression, it is well made and all the ports that are needed are present in sufficient number. It is quiet, just a little too quiet m ometimes because it has switched off. Now the work is a 350W power supply, which would have every reason to shut down due to overload.
