I have just changed my Corsair 500W power supply to a new Antec 550W psu. I bought this power supply because it was rated high and didnt had any problems in it. But after installing it in my system, it is making a crackling sound when I start my computer. I have made sure that the fan is not touching anything lying in its way but there is nothing. Can anyone tell me whether this Antec PSU is dead on arrival? Thanks for any replies.
