Is 650 watt good for Sapphire r9 280x, dual-x?

Hi, i already ordered all of my computer parts, but after reading 750 watts is required for the video card, I got a bit scared, knowing that i already bought my PSU before the Video Card.
I also got all my pc components, its just that they need to be shipped first, so im hoping i could get it saturday, I dont really wan't to continue to wait, because ive been looking for deals for about 3 1/2 months, just finding good deals on my components. Anyways, back to topic. Is 650 watts ok for Sapphire R9 280x Dual-X? Also, i do plan to only overclock my processor, but only at 4.2 GHz, and i am not overclocking my video card, incase that info is important.
