This is bad and you should feel bad. Why would you intentionally restrict yourself to only being able to effectively deal damage with your utlimate? Sure you can buy Nashor's Tooth and Lich Bane, but even at 600 AP you'll end up with 105 damage per auto-attack and 450 damage every 2 seconds, assuming you're using Lich Bane properly. Let me do some math for you:

An optimal build for AP Ashe would look like this: Ionian Boots of Lucidity, Rabadon's Deathcap, Deathfire Grasp, Zhonya's Hourglass, Lich Bane, and Nashor's Tooth, granting you 713 AP and 40% CDR (including masteries but not runes). This build costs an expensive total of 16,580 gold. With this build, Lich Bane will do 535 damage and you will deal 143 damage per hit from you ability power.

With Ashe's attack speed and Nashor's Tooth you get to 1.471 attacks per second at level 18. The Nashor's Damage combined with her base attack damage gives you a grand total of 241 damage on hit, for a total of 355 damage per second. All of these numbers are rounded up.

With 40% CDR and optimal usage, you will be applying Lich Bane every 2.4 seconds by using Volley. This means that Lich Bane increases your DPS by 223. Volley will be doing 178 damage every 2.4 seconds, another 75 DPS. You can use your ult once every 48 seconds to deal an additional 1313 damage, increasing your DPS by 28.

Your total DPS on a full build AP Ashe is 681.

But now let's talk about burst. We'll assume you Ult, Auto, Volley, Auto and get two Lich Bane procs. This nets you a whopping total of 3042 damage over 4 seconds (two Lich Banes = 4 seconds). That's before resistances and is a pitifully low number as far as burst damage is concerned.

All this assumes you were capable of reaching level 18 and full build, which, if you ask me, is completely impossible with how terrible this builds damage numbers are. Any ADC with simply an Infinity Edge and Phantom Dance will get comparable auto-attack DPS for only 40% of the gold. In short: Never play AP Ashe unless you have no desire to win. At all.
