Best PSU for my build

[Rodramble]

Need PSU suggestions for my new build.

GA-MA790X-UD4P
X3 720 BE
HDT-S1283
8gb Patriot Viper DDR2 1066 2.1v
HD 4850 (maybe crossfire in the future)
1x WD640
1x Asus DVD burner
4x 120mm fans
1x 140mm fan
NZXT Sentry LX

Would like headroom for OC & future GPU etc.

What are you looking to spend? For what you have now a good 550W PSU is fine, if you want to CF 4850s a good quality 750W.

Corsair TX650.

looking for the best bang for the buck $100 or less. (US)

Well if you really do want to crossfire a couple of HD4850s then there are not many choices below $100

Corsair TX750 for $100

That's my budget, I might could go over a little but money is tight.
Maybe I should stick with what I need now. Someone recommended LS-550 seams like a good choice.

How about EA650 for $60 & free shipping. Compared to LS-550,TX650 and TX750 thoughts?

 

[theAnimal]

EA650 would be a very good choice.

Corsair TX850 for $110 AR at newegg. Although, I really don't think dual 4850's would be a wise choice. It would have a combined cost that is more than a single gpu, lower reliability, lower min frames, more heat, more power, low VRAM, and by the time you buy it will probably have a price drop.

Thanks for your opinion.
