Upgrading my video card, question on power supply?

I'm upgrading my video card to EVGA GeForce GT 430, Requirements Minimum of a 300 Watt power supply. (Minimum recommended power supply with +12 Volt current rating of 22 Amps.). The power supply I have now is a CoolMaster 460W, +12V1, 18Amps....+12V2, 18Amps. Will this be enough amps for the video card? What problems would it cause?|||Yes , it will power your new GPU fine, you might not see the cards full potential but you will notice better graphics|||Yup, that will be more than enough to support the video card. You will have no probems. Enjoy!
