[kjartanp91]

How big PSU do i need for 3x 1TB hdd, 1x ssd, intel i5 3750K, 2x hd7870 using crossfire, dvd/cd drive and 16 gb. 1866ghz memory?

i would say 650w, because of the Crossfire configuration.

650 watt will do it but for overclocking and safety get Corsair TX750w

You will need a good 600W or greater and make sure you have at least 4 6-pins.

This is a better price than the 650W right now. XFX 750W http://pcpartpicker.com/part/xfx-power-supply-p1750snlb9

If you want modular this is a great buy http://pcpartpicker.com/part/xfx-power-supply-p1750snlb9
