geforce 9800 minimum power supply?

[movingincircles]

Hello, i have an antec 430 Earthwatts psu, should I get a new one if I were to buy a Geforce 9800 card? (only planning on one video card, no sli). In other words, what would be the minimum watts needed for the 9800 card

Currently i'm running a core2duo E6300, 2gigs of ram, 3 hard drives (2 PATA, 1 SATA), one dvd drive, and a couple of PCI cards for USB+FIREWIRE expansion, and a PCI-E x800xl ATI graphics card.

The cards aren't out yet, come back in two months. I would estimate around the same as 8800GT consumption, and I would want something 500W+ if you have multiple hard drives/are overclocking.
