PSU Crossfire Question

This is my current PSU: http://www.evga.com/Products/Product.aspx?pn=220-G2-0550-Y1

 

I had an idea of wanting to crossfire my RX 470 4GB with another one for more performance.  (Yes i know i could get a 480)

 

This is my current build: https://uk.pcpartpicker.com/list/jrqXd6 ( with another rx 470 added to it)  Would i be short of wattage if i were to do so.

 

Thanks, sorry for a dumb question

Sell the 470 and get a single 1070 instead of 2 470s

Well as far as I know the RX470 uses around 150 watts of power. Meaning two of them will use aroung 300. You still have 250 watts. Now, I suppose if you do not have vehicle radiator fans installed in your PC then it is just fine with 550. But yes, as @nerdslayer1 said: 650 would be better.

Without OC it should be fine, so there is no need for a new PSU at all.
