ASUS P5E3 Premium - Qs regarding PSU and GPU

[Tinki3]

Hi there,

I was looking into buying a 790i mobo and flagged it as I heard it was loaded with problems and that Intel boards were more stable.
Also Nvidia seem extremely over-priced at the moment and ATI 4800 GPUs give huge bang-for-buck.
So, I decided to go with Intel for a mobo and ATI for GPU.

I was looking online at a store and found the "ASUS P5E3 Premium" mobo.
It looked pretty decent and had some good reviews so I decided to plan on getting one.
I will be hopefully be running 2 4870s in Crossfire OR 2 4870X2s (or whatever they'll be named).

However, I'm a little edgy as to what PSU to use;
I was looking at an 850w Thermaltake Toughpower but was unsure whether it'd be compatible with the Intel mobo I was planning on getting?
Also, if I ever decided to get 2 4870X2s, would 850watts be large enough to run them smoothly?


Thanks.
