Hi the support of thermaltek is realy bad. i have also a bad PSU with 10 years of warrenty. I also bought this 3 years ago and after 1 year it dident work any more. I godt it replays from the dealer but now this newer one is behaving strange. The one i have is PS TPI 1250D. Alsp have made a RMA from Thermaltake home page but now answer. Hmm. Good luck with your's - Kind Regards Lars
