How to "Get a Native 2 x 8-pin to 12+4 pin cable"

First time, the Application status shows "ASUS Event notice - Information missing".
When I made the application again with all information, it shows "The product number entered has already registered for this event".
What should I do?
I can not understand why it is no doubt I bought the "4000 series graphics card together with an eligible ROG power supply", but I need more than a month to prove that.
