wattage = voltage X amps
Look and see what your amp rating is on your units power supply , then multiply it by your voltage (usually about 120 VAC).
This would be the TOTAL available for your system tho, and other things are using wattage too.
You could get at ammeter and see what it is drawing without the graphic card to see if there is still more available capacity. The 450 W would be about 4 amps itself.

Usually you can find the wattage output for the power supply either on the back or side of the PS. For the side, you'll neeed to open the case (usually the left side of a tower or top of a desktop).
Hope it helps.

open your computer the power supply has a sticker on it with all the information. oh and when it comes to power supply it's not just the watts but you also have to pay attention to the 12V rails.

go into the computer and look around the big metal box on the inside top that has a bunch of wires coming fro it that hook up to everything else in the computer, that is the power supply incase you didnt know
