Power Supply suggestion

Hey guys, I'm having a hard time deciding which of these PSU's I should get. I'm upgrading from a Rosewill RG630-S12, 630w unit with 50A (Manufactured by ATNG), which is slightly underpowered for my current setup, moving it to another PC.

The Corsair looks nice, makes 58 Amps. They are refurbished units so I'm not sure about this though.
I heard these fail quickly because of the fan profile, is this true?
Everyone ooh's and ahh's about Corsair PSU's though so at this price it seems good.

VS.

This Rosewill makes 62.5 Amps so it is appealing over the Corsair because of this. Also not a refurb... (Also manufactured by ATNG) I've heard a lot of bad things about Rosewill, but my unit has served me very well for the past 3 years. Tough choice.

Just found this and am seriously considering getting it. EVGA seems to have a really good track record with PSU's. The unit serves up 62 Amps, a reputable name, for less than the Rosewill, only downfall is the rebate.

Also open to other suggestions!
Thanks!

If you don't require modular cables I would spend the extra money and pickup a Corsair CX750. I run the CX/CXM series in most of my builds and haven't had any issues with them yet.
