Bought an OCZ ModXStream Pro power supply about a year ago. Worked great for 3 days, but then it died for no reason.
This too has been my experience with OCZ... Couple died after a few days, and a few more died almost
exactly a week after the warranty was up...
Just hope you get lucky, and it doesn't break twice in the five year coverage. They would not replace my replacement after it exploded a week into use...
