Evidently Antec's SmartPower 2.0 series had a really bad run about 8-12 months ago, and now hordes of them are dying. I ended up with one of these and, like the others, it suddenly began making a loud whining sound and died shortly after. This seems to mainly affect the 350 and 450W models. Just a heads-up in case no one knew about this. I had a 450W and replaced it with a 400W, so hopefully this one won't die
