Hello, I have had 2 power supplies i bought from corsair.. the HX850W that fried all my DVD drives and HD drives...they said thats impossible that 2 would do it...i sent 1 back over a month ago that the guy said was fine at tech support and i am afraid to send this back because they mite say it has no problem which my pc repair guy said it is defective...should i return it or send it to someone else to get a fair shake
