So without a custom ROM, i've had to settle with fine tuning WattMan. I'm happy with the final results. I probably could have undervolted a little bit more than this, but I wanted stability, so i'm happy with the current power consumption levels.
I'd like to thank
@cpluscote and the other users who have helped me to get to where I am now
3 x 480 PowerColor Red Devil 8GB, Windows 10 Pro, Crimson 16.8.2 hotfix drivers, Claymore v6.4, ETH/SIA dual mining.
~28.1MH ETH and ~435MH SIA per cardTime for me to catch up on some sleep

Modding my reference 480 to optimize the memory timings made a big difference.
@Truthchanter I flashed the latest PowerColor ROM that was just released to the public in order to unlock the clocks on the card. Without flashing the card with the latest ROM update, you may not be able to set clocks as I have above.
I would love to modify the memory timings but i'm a noob in that department. I'll wait for someone else to test and release a ROM with those adjustments before I try myself.
Here's the rom I'm using on my 480 devil. I added boysie's settings from powerplay, powertune, gpu, memory and timing (1500 to 1625, 1625 to 1750, 1750 to 2000).
Dual mining: -ethi 16 (29.9 - 30.4) -dcri 22 (322 - 335) and -tt -100
I take no responsibility if this destroys your card. I have only tested this for the last few hours... stable so far.
Edit: 240w at the wall w/ EVGA g2 1600
My OS automatic restart after your setting
Thank for your share. It's automatic restart 4th.
I use it for 2 days. After i edit wattman, it's crash.
I'm try to edit it at 1am. )
@imperialtex what error?
@bctopics I copied what boysie's had in the slower v2 rom he posted into the unlocked rom from powercolor.
Now, i can't run more than 1 hour.
Some error with wattman, after i edit his share. Now, i can't run my edit anymore. Damm it! I'm going to work, so i lost 1eth today ( 1 eth today, 0.5 last night)
LOL

After i use hasher share, my windows 10 automatic reset ( 45-1hours)-anytime-
I'm sick with that problem. It's always take me from 2 to 4 hours.
