It depends a lot on the quality of your power supply. Post your exact power supply, model number etc and I am sure someone could confirm it if will work.
Also the age of the power supply comes into play as well.

You should be fine, give it a go!

nobody going to ask what the rest of his specs are?

and no way in hell I would fool with crossfiring two old 4890 cards at this point. you could just sell them both as even a sub $150 7850 will beat 4890 crossfire.
