PSU with a GTX480 upgrade

[Odc]

I'm a bit out of date when it comes to PSU's these days and presume that my current one wouldn't be able to take an upgrade of a GTX 480 or something of that nature. (Check out my system specs <----)

What kind of wattage am I looking at for that upgrade? I'm guessing something at least 750W?

should be ok with the one you've got if you have the right physical connectors....

an 8 pin and a 6 pin.

I've been using a Zalman PSU on a test rig that's only 550W and that's been running fine with my GTX 480. Overclocked too!

Oh awesome. I was convinced I'd need an upgrade!
