I have two R9 290s arriving in the post soon and need to know if the xclio greatpower 1200w will run them in xfire?
The 290s have 2 8pin if I'm right? Meaning I'll need 4 8pin?

The power supply only seems to have 3 6pin and 3 8pin, and does it matter if I have blue and red (3 and 4 volts) going into the same card??
