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...

A ~600W unit from XFX, Seasonic, Antec, EVGA (G2 and P2 units only), or Corsair (AX, TX, and HX units only) should do.

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

heh ok, if you're building a new system the price difference between 500 and 600W psus isn't that big anyways.

I found this one: http://silverstonetek.com/product.php?area=en&pid=295 . I hope it will be sufficient. I'm getting it for lower than a 500w's price. Thanks.

the smaller 600W Strider Essential didnt do that well in this review

the biggest problem was the low quality main cap, but if the pics on Silverstone website are accurate they have used better caps in the 700W model, so that should be good.
