I have the power supply at a retailer simply as "taken" as I had bought a R9 290x AMD. The power supply as such seems to me very easy compared to my Thermaltake Hamburg 530 Watt. It also provided for about two weeks its performance in a FX 8320 @ 4,2ghz. From now on the same but went out of my PC and could not be started. The power supply was defective and could be exchanged. Mind you do not spike took place. It adopted just in Idle / Windows.
