PSU Wattage

[Asen]

Hi there,
I have an Asus h87 plus motherboard., an i5 4670, Corsair Vengeance 1600Mhz 8 Gb, a WD 1 Tb Caviar Black drive and I want to put an gtx 870 ( I know it's not out yet, but lets say it's like a gtx 770) and I have to change my PSU because this one has only have to power the iGPU and the other things which I listed and I think its crap if I want to put a high end GPU, what PSU do you advise me to buy. I was thinking of an RM 650W is it too much or better the 550W?
