GEForce 8800 in a Xion II Case (450W PSU)

Folks,

I am considering buying a GEForce 8800 for my new system. Specifically, this one:

Currently, I have a XION II case with 450W PSU, as follows:

At present the system has:

Asus M2N SLI Deluxe MB with AMD X2 5000+ CPU and 2x 160 GB Sata Hard Drives.

I am wondering if I am going to hit a power bottle neck of any sort trying to install this card. I don't know very much about power consumption so it might seem like a somewhat newbie question, but it is what it is

Oh, if it won't work, any recommendations for a good card (180-215 or so if its not an 8800) would be more than welcome!

Thanks in advance.

Thanks for the quick replies.

A couple of things. First off, I don't have the luxury of holding off on buying a video card at this point as the system does not have one at the moment and I am not willing to waiting a few more weeks to get it going, so I'll be buying SOMETHING

As far as the power stuff goes,

Here is the manufacturers picture of the specs:

As mentioned by mpilchfamily it does only have 18A on a single rail from the looks of it, so I suppose that limits me somewhat.

The next question would then be, what would be the best I could do for a video card that would run on that system? Unfortunately, I do not nor will I have the funds in the near future to buy a new power supply AND a 8800 so something else will have to do, which I can live with.

Acording to it specs u will need atleast a 500w.

Myself got a 750w thermaltake

System
intel 6600 cpu
8800 gtx leadteach
2 gig ram
250 gig hd
asus comando mb

my 2 pc have a 7950 gt in it with the same specs as 1 pc

my psu is a 550w coolermaster and i think it ma be to small

Game's like bf2 sometimes freezes up and have to restart pc

Go for atleast a 600w
