That should be totally fine. Not sure, but it seems like Dual 22 amp 12v rails with 32 amp combined? Even an Antec earthwatts 380W (27 amp combined 12v) can power a 9600GT no problem, not sure on what those cost out your way.
Basically look for a name brand with 26 amps 12v, and a pci-e power cable, and you will be fine. 20-22 amp 12v may even do it, but if buying a new PSU, I'd go higher.
