Hello!

I want to know if I can place 2 ATI HD5070 in crossfire mode in my Alienware Aurora with its 850 watts power supply?

2 5070's?

I am sure you mean either 5870 or 5970. Which?

Yes, depending on the quality of the PSU...

Corsair, Antec, SeaSonic for example, you should have no issues with dual 5870's.
CoolMax, Rosewill, XION for example, you might not be so lucky
