Im planning to upgrade my PC and see if I can keep my current Antec Neo Power 430 power supply for my new build:
-Antec neo power 430 watts with 25 amps on 12v rail
-eVGA 7900 gs KO factory overclocked (needs 20 amps on the 12v rail)
-Phenom II 550 callisto at 80w stock power consumption- this will be overclocked hopefully up to 3.7 ghz
-GIGABYTE GA-MA770T-UD3P AM3 AMD 770 ATX AMD motherboard
-filling my ram slots with a total of 8 GB at 1066 mhz (not overclocked)
-just 1 hard drive and maybe 1 or 2 dvd-rom drives
So I'm wondering if my power supply is good enough to power that overclocked video card (20 amps) and that overclocked cpu (unknown amount of amps)
Details about the power supply here:

Basically it can output 430 watts at 50 degrees celsius and the review says it can output 25 amps on the 12v rail.
question 1 Do you guys think I can safely run my new build with my current power supply?
question 2 And what if I went even further and also unlocked the 2 dormant cores of the Phenom II X2 550 and turn it into a quad core, would the quad core at 3.7 GHZ overclocked consume more power and would the antec neo power 430w PS handle this?
question 3 How would the CORSAIR CMPSU-450VX 450W handle the builds of question 1 and question 2?

Thanks for any info. This will be my first overclocked cpu and I'm looking forward to it. It seems really easy to do with bios interface and simply changing the multiplier.
