Not so much the electrical de-rating, but the mechanical de-rating you have to worry about. Unless your winder is really experienced with choke load inductors, expect some nice physical hum/buzz from the unit. Make sure your working voltage rating is +800 as the choke gets beaten pretty hard.

Play with DuncanAmps.com PSUII, it will really help you visualize the supply and it will tell you your problems. You can put in stepped current demand to see how the filter works at various draws.
