I've an old system from 3 years ago and I decided I would upgrade my graphics card to the ATI 5570 1GB version. I learned that my power supply was not enough to handle my system with the ATI 5570 card. I need help with selecting a power supply that would handle the current specs of my system. I have no intention of upgrading this one as I would rather buy a new pc. That would take a while so I would rather this worked till then.
The specs are as follows:
Intel Pentium D 945 3.4Ghz
Intel DG965RY motherboard
500GB Seagate 7200RPM HDD
LG DVD+/-RW 16x
1.5 GB DDR2 RAM
The current power supply I have is a Zebronics one with 400W rating. And after a bit of research I found that it depended on the Amps on the 12v rail. My current SMPS has a rating of 17 amps on the 12v rail.
After a little bit of searching, I came across dual rail power supplies. I do have a question here, do both the rails supply power seperately. If so, Can I install the Coolermaster eXtreme Power Supply 460W? Will it handle the load of my system. Or do I need to find a power supply that supplies 24A on a single 12v rail according to msi's graphic card requirement page.

Any suggestions are welcome.
PS: The ATI 5570 is a passively cooled one.
