Hello all sorry if i ever trolled you.

Im mounting a Crossfire capable machine, piece by piece bit by bit. Money isn't on the strong side.
Im not doing the crossfire now, ill wait a bit for the prive of the 4850/4870 lowers a bit and the coolers that come with it improves. So it goes a bit like this.

So far i have a nice cooler and case. Ive been checking a corsair 550W PSU.
Ive read that yes, it is capable of Crossfire 2x4850. Seen Anand and Toms reviews (and many others when it launched) but i think 550W can be short. I think it will do, but 550w seems really short with almost no headroom. Im think on a Phenom or a 6400+ X2 (but that i will see at the time) and a top notch mobo aswell. I know im strange but i like to buy this way.

Basicly it is a 550W PSU with a 12v/41amp Rail.

Give your estimated guess ofc. I know you need all specs and stuff, but hey, more on that in December/January. I like to save money then burn it in Hardware :) 
I leave the specs here and the link to the Corsair product page.

I went for the Corsair TX750. 60 Amps on the 12v Rail and more headroom. Thank for reading i guess.

Yup. More headroom. About 400watts of headroom.
