System Specs:
i5-2500K
Asus P8Z68-V LX
7200 RPM Hard Drive
CD/DVD
2 120mm LED Fans
Possibly a SSD

And then a GPU:
560Ti, 560 SC, 6870, 6850 or 7770


I currently have the Cooler Master eXtreme PowerPlus 600 Watt
I know its not the best PSU, so i am open to replace it if the community feels its absolutely necessarily.
If you guys think it will be sufficent, as i wont be using a power-intensive GPU, then i will keep it.

Here are some of the options:

This was one that i was really interested in

If i do end up getting one, I'm basically tossing the CM EP+ in the trash (literally). So unless it's worth it, like 100% worth it, then i will stick with the EP+.

Opinions Please?

You're right, the Cooler Master eXtreme PowerPlus 600 is basically a low end 450W PSU. I would prefer any of the XFX or Corsairs in your list. The one you 'really like' is a suitable choice. If you haven't already gone there, check out http://www.jonnyguru.com/modules.php?name=NDReviews
And use a PSU calculator like http://www.thermaltake.outervision.com/
The graphic cards in your list are not huge current drawers, so a really high amperage +12V rail(s) isn't an issue. For instance, the 560ti draws 16.5A at max load. Something you almost never achieve.

Im pretty sure it delivers about 500, but even if its 450, is that enough for my build?

Or do you think its worth the extra $60 to get that other one.
