AMD fx6350 + GIGABYTE gtx660 + 1 x1Tb hdd + 1xDVDRW on an Asrock 970 Extreme4 . This machine already burns 2 psu the first was 450W and the second was 550W .Although either two of them were Corsairor thermaltake or any "Good " and expensive brands , the first was Powertech 450w and the second Hantol 550w. Is there any case to have Something faulty on my built wich burns every psu that I am installing???
