I apologize ahead of time. I'm sure questions like this are asked all the time. So, again, I'm sorry for the repetition.
I was originally going to go with a higher wattage PSU, but I was told that it's the amperage in the 12v rails that matters most, and that a 550W would be fine. I'm kind of skeptical, though. The guide here recommends a 750W PSU for the two cards I may crossfire in the future. So I was wondering if this will be fine? And would it still be fine should I crossfire down the road?
I don't want to end up blowing up my computer due to some bad advice, or something. If the PSU won't be sufficient, could someone recommend me one?
