The 4850 "450 Watt or greater power supply with 75 Watt 6-pin PCI Express® power connector recommended"

I wouldn't trust an Antec Smartpower to power anything.

E4400 @ 2.4 GHZ (I don't mind to return to stock), 2 Sticks of 1 GB DDR2 800mhz, 1 Sata DVD-RW, 1 IDE CD-RW, 2 Sata HDs (250 and 160 GB), Creative X-Fi platinum.
I googled and read that 4850 takes 22 amps.
These are my PSU Specs: http://www.antec.com/specs/SP400_spe.html

Which rail does it use? 12v?
