If you measure by WEIGHT, it should be about the same. When measuring by
VOLUME, cane (sucrose) and corn (dextrose/glucose) are slightly different.
Also, when you say "powdered" it makes me think of "confectioner's"
powdered sugar, which has other additives like cornstarch that
would change the fermentability of it. That would be a reason
"confectioner's/powdered" sugar wouldn't produce as much carbonation
as corn (look up "confectioner's sugar" on wikipedia.com).

I just use plain granulated table sugar, measure by weight (4 to 5 ounces
by weight per 5 gallons).
