Actually you can power a system with two PSU. But no if you look at EZcool's psu reviews their not very good at all. I'd just stick with a corsair 430 or 500W if you're on a budget then a SeaSonic 520W or a OCZ 550W if your not (look at it's good reviews before you say it isn't a good PSU). http://www.newegg.com/Product/Product.aspx?Item=N82E16817341050

I'd bet the computer cold run on a 430W your have more than enough power.
I'd check out this site when you have questions on wattage, if has a amps calculator but you have to pay then . http://extreme.outervision.com/psucalculatorlite.jsp
They update it quite often (whenever there are new parts out) so that's the only time the site is down.
Why 2 PSU's Just get one.. 550W PSU will be able to handle it. but i suggest to get a bit better 600W PUS just to give you that Extra Power if you need it for some reason..
This is a simple setup so try and go with 1 PSU if you can there no need for you to have 2 PSU's.
well, since i'm computing at the age of 12 years and now i'm 18s but I've never heard between the two psu's in one system how is that possible,
i guess the @OP actually mean that those are the two options for him/her which one to buy, am i right?
So my vote goes to Cooler Master gx 550w, it is very good model in GX series for mid-range cards.
He is asking what is better between the 2 not if he can run both at once.
I would not use either Coolermaster or Thermaltake. If you want a quality unit stick with Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ or Antec.
What Core2Duo are you getting? For the most part you will not be getting much of an upgrade going to a Core2 from a Phenom II x4 840.
