Thanks, that's what I was thinking.
However, they only have 1 750 in stock atm you think I will be ok with 1 750w for 4 cards and the CPU? I will buy another 750w later when I add the other two cards?

It would be better if you could get 2x750 at the same time. It'd be a waste to just buy 1 now. You won't be profiting on half of your cards in an indefinite time until you get the second one.
