Your PSU will be ok for the 9600GT, but if you upgrade to anything more powerful or power hungry, you most likely will need to upgrade your PSU as well.
Thnks for the reply guys...
I'm having a second thought buying a PALIT 9800gt...
Is this card going to have a problem or will it run this card smoothly?
So have you tried 9800gt with a superB 460w???
I'm not going to OC or anything because Palit 9800gt i think is factory OC'ed and i don't want to OC any further(from youtube review^^)
What do you think should i buy this PSU?
How can i know the Amps and what is 12v rails??? I'm noob in PSU^^...
GPU"s need external power from the PSU via a 6 pin connector if I remember correctly that is powered by the 12v rail. That'sa why a GPU specs on its box will say like 26 amps or something. Some power supplies haves a single 12v rail with 50 amps or more, while others have 2-4 rails with 18 amps.
If you haven't bought it yet then go with this or the VX450.
