I'm just not sold that its the PSU being bad yet.
Have you tested for RFI, other than using your TV no. Have you used an oscilloscope, no. A meter will not tell you about this kind of fault.
The only test you have done is swapping the psu over and now it causes problems when you turn it on.
What more evidence do you need. RMA it now, back to the shop, with the email from ocz, whilst its new, the longer you wait the more likely they are to claim there is no fault.
