I've got a Carbon fork, but it doesn't have a carbon steerer..... I'm using the True Temper Alpha Q with a Ti steerer, however, I'm a long way from 380. (I'm 220) So I can't honestly say it would be OK for you, check with the manufacturers.
I also ride a Fixie, just watch your gearing, start out in the mid 60's in gear inches and you'd be ok.
