Shuttle 400w PSU and system upgrade?

[Thermite Paste]

I want to upgrade my system, but I'm not sure my PSU will be able to handle it. Currently I have a 65w processor, and a 7600GT (not sure how much power it draws) in an SN27P2.

I'm looking to upgrade to an Athlon X2 6400 (125w) and an 8800GT (not sure, but I know it draws more than my current one.)

I know shuttle PSU's are usually better than the desktop equivalents, but will my current PSU be enough for an upgrade?

What's the max amperage on the +12V rail?

If you don't understand what I just said above, can you please find or take a pic of the side of the PSU where it has all those numbers? Looks something like this:

I think it's 10.5A, but part of the label is obstructed by a cable guide so it's hard to tell.

That's strange... it's not showing up like I posted, even though I did :/
