the back of my 7800GTX boxes suggest 400 watt power supply for one card and at least 500 for two.
With the high end agp cards, they use the 4 pin molex connector. With the pci-e cards, they either use a 6 pin connector from the psu or a dongle that comes with the card to plug in two 4 pin molex connectors.
I would get a larger psu.
