Console gamer's 1st build

R9 290 = one pcie x16 slot = 75w one 6pin pcie power connector = 75w one pcie 8pin power connector = 150w = a maximum total of 300w meaning you can not pull more than 300w's with that card no matter how much you oc.

In practice you can pull more than 300w
 
Okay, I've pretty much decided on the RM series. Now I'm considering whether to just get a 650w for my one card now or prepare for potential crossfire in the future. Anyone got any idea how much wattage i'd need for this? I've seen comments that 750w would be fine, to others saying you'd need 1200w!
