Did I buy enough PSU??

I just purchased a brand new system, which everything has arrived now except the case and PSU. The components I purchased are:
AMD Phenom II X4 955 Black Edition 3.2Ghz quad core CPU,
ASUS M4A78 Plus mainboard
Gskill Trident 2 x 2GB DDR2-1066 5-5-5-15
XFX GTX260 c216
Xclio Windtunnel full tower case
and this PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817341019
OCZ StealthXStream OCZ700SXS 700w PSU

Nvidia recommends a minimum 620w PSU for single cards, and 680 for SLI... I have only one card, and never plan to use SLI, but, I heard that I needed a PSU with 24a on the 12v rails, and the one I just bought only has 18a, if I remember correctly... Think this will be enough??
I'm a bit worried about this, I see others using Nvidia 200 series cards on PSU's even smaller than this one, I just don't want to be the exception..
What do you think? My case and PSU will be here Saturday...

EDIT: Forgot to mention, to anyone looking to buy a GTX260 graphics card, see the one I listed??? If you search newegg, you'll see that there are TWO listings for the same card, both are XFX GTX260 core ed. core 216 models, same clocks, same box, etc... both come with the 2 free Nvidia gift games, CoD World at War (disc) and Terminator Salvation (download), BUT, the one I listed, if you look at the pictures of the card, you'll see that the picture showing the box's contents show that FarCry 2 is in there, although Newegg doesn't mention it... the other card doesn't show this game... I bought this one hoping that it really contained that game, and it DID. So, anyone wanting one of these cards, get the one that shows Far Cry 2 bundled with it in the pictures. It also comes with another game, "Mirror's Edge", although I don't know anything about it...

The amps you see for the GTX 260 are the minimun total for the 12V rails for the average system. Your has 56 amps. total on the 12V rail/s
 
So that means I have enough??
I'm still a little new to the in-depth details of PSU's, even though I've been building systems and working in this business for 10 years now... I always just bought the biggest Antec or OCZ I could afford and forget about it... Just want to make sure I'm safe with this one...
 
The stealthxstream will run two of those cards in SLI, let alone a singlecard. Those ratings should be taken with a grain of salt, as those are usually not referring to quality power supplies. Heck, on a good 500W you can run a gtx260c216.
