I have the power adapter now about 4 months in operation. It runs without complaint and is quiet. Aaaaaaaber, you have to get it up and running first! After my old (3 years old) Be Quit 500W NT was blown, I want the manufacturers still have a chance to give and have this ordered here. Thanks to Amazon, it came fast via DHL! But when I had joined it, did my PC no Mux! Have motherboard (Asrock AOD790GX) bought and installed, again no Mux! Power supply to other PC's tried, at one it was, not the second. After some perplexity I had the idea to connect the 20-pin ATX power connector only at the motherboard and the 4 additional pins to omit and the PC started! When I put the 4-Pin ATX to make the PC no Mux. The NT is probably not compatible with all motherboards! I then bought out of curiosity a 20 to 24 pin adapter to keep it running well. I do not know what Be Quiet did there, but I'm not the only one with this problem! On a forum was to read that it happens often times, that certain power supplies do not harmonize with certain motherboards.
I can therefore recommend the NT limited! What is positive, there is only cold air from the NT, my old was much warmer! And the power should be sufficient to virtually any system!
