[URGENT] PSU for the BFG 7800gs oc agp

[rxzero]

hi, i have recently brought a BFG 7800gs oc agp, and figured that my psu isn't upto scratch, so i've decided to purchase a new psu, but isn't sure if i'm looking at the right ones so that the new graphics card and current system will run smoothly. here are my system specs:
GA-8I848P-G
northwood P4 2.8ghz
1GB ddr-sdram
2x hard drives
1 dvd drive
3x fans
7800gs oc agp
the current psu i'm looking at is: http://www.antec.com/specs/SP500_spe.html

please provide advice/comments if this psu is sufficient, as the minimum specs recommended by the graphics card is 400w with current ratings on the 12V rail at 20A, but since this is dual 12V rails i'm not sure.

-thx-

It is more than adequate for your system since it can provide a total of up to 36 amps on the 12v rails.

500W is MORE than enough. My current rig (see sig) is powered by a TT 550W...does it like a champ.

I am close to the above setup, just 2 more HDD's, and Opty, and 2 GTX's and my pc never consumes more than 300W. I am using an Antec 480 PSU.

yah 500w is over kill, get the antec true power 430w or 480w
