This is the system I will probably build. T'M GOING TO BUY ANOTHER 1GB 4780 in the near future so the power supply needs to consider that!

Well if u are not gonna add another graphic card and nt overclocking, then 450W is more than enuf...
But if u are jus gonna overclock and not gonna add another graphic card and nt overclocking, then 550Wis more than enuf...
But if u are planning to verclock and add another gfx card later, then get atleast 700W PSU..
But be sure u get top tier PSUs...

sunbeam is two thumbs down. Try to stick with compainies like Corsair, Antec, or PC Power & Cooling. Probally going to be your best bang for your buck psu's and still maintain a high lvl of quality. Like dokk2 said, "Do not fool around when buying a psu." There's a good chance it'll be more than the psu you'll be replacing if something goes wrong.

With just the listed components, you'd have to try hard to even draw over about 300W. A 600W or so supply would give some room for future expansion (a second 4870, a quad, etc), so it would be a good choice. The 650TX is an excellent choice in this category. If you just wanted to run the system as specified above though, you could easily do it with a good quality 400-450W, such as the 450VX for $30 less.
