I am experiencing this exact problem. It seems like your support staff are either horribly over-worked, or exceptionally lazy. I'm very happy that I made the choice to buy a brand new (defiantly NOT thermaltake, after this expereince) power supply to replace my thermaltake, which died under warranty. That was many weeks ago and I've not received any sort of confirmation that the RMA request was even received. I purchased my thermaltake because it was supposed to be good quality and had a 5 year warranty. Turns out neither of these things were worth it.
