Corsair HX1000W USA has a burned 24-pin

[Lu(ky]

Hello,

I was using this HX1000 PSU with my current specs in my sig. I notice one day the power supply came on and started to go off again back in forth deal then it basically started to power again. After that my Asus Rampage Gene II Micro x58 would not load windows, everything including PSU came on with a blank black screen. So I started to tear it down and when I got to the 24-pin connector I notice a burned in pin on the 4-pin attachment part to the 20-pin was melted. I also notice it was melted into the motherboard 24-pin. Do I need to setup a RMA or do I need to call tech support first? I tried looking for the number on website could not find it.

Thanks
