New Build - Questions on PSU, CPU cooler

[Bablos]

Hi There...

My AGP graphics card is knackered on my current PC, so rather than source a decent replacement from the now dwindling list of decent AGP cards, I've decided to bring my new build forward several months.

So, on to my questions;

1) I'm planning a PC based around a Conroe 6600, 2GB PC6400, GeForce 7900GTX, 2 HDs, 1 optical drive, 3 or 4 fans. Just wondered what kind of PSU wattage I'd need to be looking for - dare I try and get away with the 420W Tagan, or do I need to jump up to a 550W or so?

2) What is the supplied cooler like with the Conroes? I want things cool and silent, so would I be better replacing it with the likes of a Freezer 7 Pro?

Thanks in advance.

I'd be aiming at 450w as a minimum really, more likely 500w if you are thinking of overclocking(and with a Conroe it seems almost rude not to ), any one from Tagan, Enermax, FSP or Seasonic ought to do in that sort of range. The 420w Tagan would probably cope but it might be near to it's limits.

I don't know about 2. really, I think that the supplied cooler is decent enough but probably not up to heavy duty overclocking, that isn't in the CPU manufacturers interests so why would they supply a fantastic heatsink when one that is "good enough" will do?
