Well, Amazon is the place you bought them from, they are liable for your warrany, not the manufacturer, so it should not be your problem, Amazon will have to take care of it.
My experiences with Amazon have been amazing; I bought two 1TB 970 pro's when they just came out (hella expensive), and one of them was faulty. After explaining my troubleshoot, they were like: ok, sounds like you know what you are doing, we'll send you a new one, be sure to return the one that's faulty in the next few days. I was blown away, amazing experience for me and certainly a reason for me to look at Amazon first when I need something else.
