What would you say is the sample size and the rate of failure? I've seen only hundreds, not thousands of PSUs. BTW, this thread is 2 years old and I happened to have my mails sorted by subject instead of by date and didn't check the year, so it seemed new. If I had realised it's 2 years old, I wouldn't have answered ... But I wonder what happened to the original problem; has it ever been solved, and what caused it?
