I have the exact same PSU and I have no problems like that. I even have my confuser hooked into a 3k transformer (German standard wiring in my house) Sounds like an issue of house current. But here is the question? Do you have another PSU that does the same thing? Another computer perhaps? Know anyone that can plug their confuser into you place and see if it does the same thing... That will at least answer that question.
