Good day
I would like to know what is the minimum wattage required to handle a crossfire of 2 cards (Powercolor Radeon R7 260X 2gb). I see according to this card's specs it requires minimum 500w, so if I want to add a second card for crossfire what will the minimum be.

Kind regards...

the card consumes about 100 watts so a 600W unit would be the logicall answer.
But seriously, if you have a good 500W psu with strong 12V rail(s) it should have plenty of power to run 2 in crossfire. (like 450W on the 12V rails, 200W for the cards, 50-100W for cpu and another 50W for everything else and there would still be 100W of capacity left unused...)

Thanx...I'll rather go with the 600w since I don't understand the rails:D
