If i Get a XFX GeForce 9800 GT Video Card and my Power Supply Needs to Be...?

If i Get a XFX GeForce 9800 GT Video Card and my Power Supply Needs to Be 450Watt and 26 amps on the +12-Volt Rail and i Have 420 Watt Will It Be the Same?|||i have a 500W power supply with 30A on the 12+ rail with my 8800gt which is basicly the same card as the 9800gt if your power supply is 420W just make sure it has 26A on the 12+ rail and it should be fine - if your running quad core then i would upgrade your psu. p.s: i ran my 8800gt on a 20A 400w psu for 2 days before i replaced it i only ran into problems when gaming which uses more power - i run pentium D 3gb ram and 8800gt|||No it will not work. Some times then up up working, but you will not get the full potential of the card.
