That "430watt" is actually a 380w PSU. The max continuous power output is 380watts and the peak rating is 430.
And its max +12v output is 23amps and not the 28amps you were hoping to see.
It might power a system with a 9600GT but I sure don't feel good about recommending that PSU.
Actually graphics card manufactures over state the power requriements for their cards. It might run it if HIPRO PSU can actually produce the 380watts and the 23a. I've read that a full system with a 9800gt only really uses under 300 watts of power.
If you haven't aready bought that power supply I would definately get the corsair WR2 recommended.
