Default Getting away with 700w Supply? (GeForce 580 GTX)

Okay, before I begin let me post my specs:

700w Power Supply (Made by Xion, or that's the label anyway.)
AMD Radeon HD 5770 1gig (Primary)
GeForce 8800 GT 512mb
4gig DDR3 PC1600 RAM
On-board sound (using Tritton AX 720 headset)
500gig Harddrive

Now that this is out of the way let me state my question.

I plan on purchasing a GeForce 580 GTX. It will be replacing the Radeon HD 5770 and the GeForce 8800 GT outright and one will go into an older computer of mine for "Just in Case" purposes, while the other is sold off.

I used a quick thing to check if my specs would work. I used's custom computer maker thing they have and substituting my specs. They say the GeForce 580 requires at least a 750watt power supply. I read a review of the 580 stating Nvidia recommends 600watt supply for single card use and 850watt supply for dual in SLI. This has made me concerned.

I want to know from someone with a little better computer knowledge than myself if I can get by on a 700watt without dampening my gaming experience or browning out my computer power.

As I said, both the graphics cards will be removed as this card, from what I'm reading is more powerful than the two combined would be even if I could have linked them together.
