4 x 47% One-Handed enchantments
Daedric Mace (567) 81 Frost Damage, 81 Shock damage
Daedric Mace (567) 15 fire damage, absorb 34 health
130% one handed damage potion
Damage output of a standing power attack = Over 3370 on Master difficulty
One shot alduin. Guess we can't test max damage

Edit: Worked out some numbers;
Alduins health during the three hit power attack
3370
1482.82 (1887.18)
Dead
Dead
Then I swapped the weapons;
3370
1535.00 (1835)
Dead
Dead
So I would have done 1887.18 * 2 + 1835 = 5609.37 damage, on master. So 11218.72 on normal.
If I got rid of the absorb/health drain mace, I'd do 1887.18 * 3 = 5661.54 on master, 11323.08 on normal
A one handed power attack with the dual elemental mace did 2525.26 damage on master
Not bad for 40 perks
