video card question

[misterfatal]

right now i have a AGP 9800pro and my PSU handles it fine. i bought a new computer that only has pci-e, and im upgrading to either a x1800xl or a 7600GT. my question is can my PSU power these video cards fine? my psu is a Coolmax CT-450. my +12v is 20A

Don't compare the X1800XL to the 7600GT. Look at either the X1800GTO or the 7600GT, or the X1800XL and the 7800GT (which both make no sense to buy now for reasons).

I can't locate the voltage information for those specific cards at the moment, however I think that for an X1800 series card your going to want at least 24-26A. Also, I'd reccomend an Antec or FS Nortron PSU, as that brand isn't really reliable. You'll also want that extra power and ampage for OCing and the ability to upgrade in the future.
