PACKING AND DELIVERY
The power supply unit arrived on time and neatly packaged for me to. In addition to the actual power supply all the necessary cables, screws and fasteners are available. What have I missed but was a sort of guide or explanation which cable is intended for what purpose. On the box the individual cables are described only briefly. As an example, my graphics card is required now two power connectors. The PCI-E cable actually has two connection options. So enough a cable to supply completely the graphics card? I first each connection indulged your own cable, as in the old power supply.
INSTALLATION
Installation proved to be fairly straightforward. First built in the AC adapter, then connect gradually the individual cables. Here I find, however, the ribbon cable is not so optimal. Only connect the EPS / ATX 8-pin cable I felt as fummeliger than with round cables of my old power supply (be quiet). The cables are relatively stiff, which makes a nifty embarrassed. For the cable management is excellent solved. You really need only connect the cables that are needed. Finally, feel and you do not hear, unfortunately, when the cable is properly connected to the power supply. This could be a source of error if you have as less idea about.
CONCLUSION
Despite the small criticisms, I am satisfied with the power supply. It is very quiet (in fact I did not hear it) and served its purpose. All games run again and there is no more emergency shutdowns. It provides all relevant security solutions for the hardware to protect, has a high efficiency and provides for a 650W power supply up to 650W on the 12V rail. In my previous be quiet it was at just over 530W 400W. And I suspect that since the problem was because Nvidia specifies for the GTX970, which must provide a power supply of at least 500W.
Finally, perhaps one more tip: One should with the wattage not overdo it, it should not be too little but not too much. This costs all electricity and therefore money.
