Mine also failed after 11 months, a good bet is to get a different brand to replace it. Use the RMA'd psu for something else or sell it, that's what I'm gonna do. That is if I feel like waiting. Mine only had a bad bearing in the fan, which I could just replace myself with a 20$ part. Too bad you can't just get your money back, RMA's seem like a nightmare through this company.
Short answer, go Corsair or Seasonic. Never had an issue with either of them. Only bought this because it was on sale for 75$ at the time, I needed more power for a GPU and it had good specs for the price.
Best or luck to ya!
