Summary: I've had two of these - the first was great, the second would turn on for a half a second, then shut down. I went to the Corsair site, followed their instructions to perform a "paper clip test" (which the unit failed), then followed the on-site instructions for requesting an RMA number and returning the part, which I sent Fed-Ex, and which they received last Wednesday (the 2nd).
Summary: Went with this Corsair because of all the great reviews and Corsair being one of the best for PSU's. It worked great for a week or two then just out of nowhere died. Waiting on Amazon to ship me new one hopefully will have better luck with it. Not happy with the downtime while waiting on another to get here.
