I have a ATX-AS500W-BK aspire psu v1.2 34A. ı have been using this psu with various mobos and cpus. I bought a gigabyte ds4 bult it and I powered it on. İt was running but there was nothing the screen I tried several times and the last time I tried unfortunately there was a flame on the upside the cpu beneath the passive cooling system. And the power suppliers of the board burned. I RMA it and they said it was because of a power supply failure so it is out of warranty. I did not have any problems with my previous systems but they were all 4 pin except the ds4 (8 pin12v) why do u think it burned and what should ı DO?
