Did I choose the wrong power supply?

I'm new to gaming computers and made my first build two or three days ago. I chose a Corsair CX750 as my PSU for my gaming rig, not knowing whether or not it could handle my other parts. The power supply died the day after I first booted it up. I have already sent the PSU back to newegg for a replacement, but I'm already starting think if I should try for a refund instead. What I want to know is if my PSU was just defective and I should stick with the replacement, or if not, should I ask newegg for a refund and get a different PSU.

My other components are: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157500

    Corsair has stated that the CX series is not intended for gaming use. So why they sell a 750w unit is beyond me. The CX is worse than mediocre, its major con being it's longevity, as you seem to have found out.

    Refund, or expect that you stand a good chance of replacement again if you RMA.
