The 9800 GTX literature says it requires 2 6-pin connectors (not a problem) but 24A minimum. Most of the modular (need explanation plz) PSUs can't get over 22A max on the +12V rails. I searched for one with over 24A and the Corsair (non modular, still needing explanation) linked above has it. I did notice only a single +12V rail? Is this compatible with the v-card?

Thanks for the fast reply. I'm hoping to get this answered and order today.

Most modular psu's have mutiple rails, and you add the total amount of amps, not only the single rail.

For example, my psu has 17A on each rail, for a total of 51amps.

I lose a few, due to it being modular but still plenty juice to run dual cards.

That rosewill should be running the card just fine, it has 36amps total, the 18 number is on each rail but you add both rails together.
