Power supply for system upgrade?

[smadge]

Hi all,

My computer stopped working the other day and I'm pretty sure that the motherboard died(It turns on but BIOS doesn't post). I'm getting a new mobo/cpu/ram combo to fix the problem. The items are here on newegg:

Cpu:
e7200 wolfdale core 2 duo

Mobo:

Ram:

GPU:
I already have a 9800gtx
Other stuff:
already have 2 hard drives, 1 optical drive.

1) What power supply should I use?

2) I have a 430 watt 18a on the 12v rail psu right now. Would it be pushing it to use this?

3) Any comments on the system itself. Am I balanced? Am I getting good "bang for the buck?"

Thanks.

ps: ignore the signature, thats my old setup.

Recommended power requirements for a 9800 GTX:

450W power supply with a combined 12V current rating of 24A or more

I'd get a 500W or greater unit.

500w will handle it but I'd go 600 for reassurance

+ 1, 600W just to be on the safe side.
