From Bitmain APW3-12-1600-B2 product page...
That's not the power supply that comes with the S7-LN, it's a Enermax 1000w. I'm sure it has a warranty, but may not be worth the shipping back to China.
Aargh, sorry, you're right. I read it wrong plus had a brainfart.
Try contacting Enermax and ask them:
