Hi everyone I have a 650w Antec Earthwatts Green PSU supply and I'm looking to power an HD5870 and my spare HD6850 at once. It isnt for crossfire but rather for bitcoin mining since I had the spare lying around.
Also if the power requirements hold, I will be using a dual 4 pin molex adapter to pci since the psu only comes with 2 6 pins which is used by the 5870.
Does this plan seem sound? Any feedback is appreciated, thanks.

Plenty of power, not many here that would advocate the use of adapters on a long term basis.
your PSU should be fine.
Also, is bit coin mining graphically intensive? iv seen bit coin around and have always wondered.
