occasionally I do know what I am talking about ....
the CX series power supply are JUNK
also the wattage means jackshit its the amperage that counts and the FX chip draw a lot of amp's
coupled with the fact that his gpu is under-powered and GTA V seemly endless appetite for cpu-cycles + his attempt to record gamplay just pushed it over the edge
either of these will be fine

I would also be looking for a better a gpu . a 5670 is woefully inadequate
Did anyone mention CX series, may be I missed it. As far as I know there are 2 CX series from Corsair that were submitted for 80 PLUS Certification, and I have not looked those up to see if they remain in production - because I ignore all CX PSUs, they are manufactured for OEMs. I use and suggest HX and TX series Corsair; I noticed that you did NOT mention them. Personally, I do not care what company someone purchases from, as long as they are aware that they should buy quality - and that was the thrust of my post above, quality. That is why I left a link for ALL PSUs from every company that submitted them for 80 PLUS certification.
Also I said, "
I am extremely tired at the moment and hope what I wrote is understandable to you. If you have questions of me, please post here." And, jonnyguru does NOT recommend purchasing garbage power supplies. I would have provided more specific power supply companies and PSU series, however as I said, I was exhausted when making the above post.
Most Seasonic are good, however, Corsair usually is less expensive. It is obvious that Seasonic is trying to get to the mainstream user with the power supply you listed from newegg. Note that I provide links for people to learn from, links to an online seller sometimes follow. I want users to know what they are buying before looking at prices.
On a side note, the last power supply I purchased for myself was a Seasonic 80 PLUS Platinum, probably not what most people would purchase, and that is why I did not begin suggesting exactly what I purchased for my computer.
I did some quick leg work for you and am providing a link to a review site for the Seasonic you mentioned, it seems to be built on an older design, the review date was May 2010:

This is Jonnyguru's review of the 850 watt version, given here to let you see how both sites review PSUs:

Do the rest of the legwork yourself to provide through reviews of any other products, that will help the OP more than providing your personal preferences for a PSU. You may be correct in PSU recommendations - or wrong, the OP will never know without a through review to back up what you say. The links I originally posted provided enough information for you or anyone else to search for further information and reviews.
The next time you comment, please take an entire post [in this case I believe it was mine], including it's thrust, into consideration before commenting on another person's post. Or, if I missed something, list the person you are responding to. NOTE: In my above post, I did not say you were ignorant, neither do I now.
Thank you.
EDIT:
Removed double comment, and edited for clarity.
NOTE: You said something to the effect that wattage was worthless to consider. I was only looking at quality, and as [I assume] you know, a quality PSU rated at 550 to 650 watts will provide both the wattage AND amps needed for a non-overclocked computer with a single GPU. And, I know all about single rail, split rail, and split rail tied into a single rail - so, keep your "educational" comments to yourself, as they are domineering and have no detailed educational value at all.
