I would like to thank Phil, Iegion and xleejohnx for helping get this far! THANK YOU!
Situation:
I have 6 MSI RX 470X GPUs running:
-each gpu hashing = 23.5mh
-total system hashing = 141.2mh
-ave wattage = 94W (range 86-104)
-total system Watts = 1115W
-total system Amps = 9.61A
-2 Antec 750 Platinum PSUs
-Motherboard = MSI Z97 Gaming 5
Question:
I am planning to goto 28mh on each gpu.
1) Would you recommend adding another gpu?
2) How many watts would going from 23.5 to 28mh add to the system?
3) Has anyone done 7 gpu's?

6 x 470 with 1000w or 1300w PSU should do it, avoiding using 2 x PSU which can introduce more complicated issues with power distribution.
Adding a 7th card will surely increase wattage and you motherboard will need to have more than 6 x PCI slots, unless using a multiplexor
I have a R7 370 x 7 using a 1-to-3 PCI multiplexor, running Win7, running strong with CDM v7.2, Crimson 16.9.2, drawing about 1200w from a EVGA 1600-G2.
7 x GPUs max on Windows, 8 x GPUs if using registry modded Windows Advanced Server, otherwise Linux can go beyond 6 with ease.
To increase hash.... if you adventurous ... you can mod your rom ... https://bitcointalksearch.org/topic/m.16476759
I've got 7 going right now on the msi gaming 5. You need a 16x to 16x riser for the main pcie port and windows 10.
Its a mixed GPU rig: 4 msi 4g 470s at 27.5mh, one 370, one 380, and a 1070.
Wow, that is a crazy rig! How many watts are your 470s pulling at 27.5mh? How did you get them to 27.5mh? What is your "at the wall" wattage?
I just ran out an bought another gpu. That makes 7 gpu's on 1 rig. The rig will only start with 6 gpu's! What can I do to get the 7th running?
Note: I can disconnect any of the gpus and the rig will start just fine, but when I plug in the 7th, it will not start.
Any ideas to get all 7 gpu's to work with this rig?
funny i am trying to bump a 4 card to a 5 card. and one card is fucking around.
as for a 7 card no way will i try it.
7 cards is a gamble imo. Sometimes it'll work first then sometimes never
What issue are you having Phil? Maybe I can help
add a fifth card and only four drivers load I get error 43.
every card works in the full slot as the 1 and only card
every card works in the 1x riser slots 1 at a time.
all combos of 1x riser work up to four cards on the fifth card fuck you bitch and it won't load.
so with all testing i did I am pretty certain all five of my riser boards are good
I am pretty sure all five cards are good
i am pretty sure the 16 slot is good.
I run windows 7 pro. so has anyone got windows 7 to run 5 boards. on a h81.?
and maybe need a simple mobo setting.
windows 7 amd driver doesnt support more than 4 amd cards i always forget you run windows 7
Okay. Since I have the card and now all five boards are 4 cards.
I am capped at 20 cards.
Unless I add to my 3 card asus z170 empty mobo that has everything but gpus.
Since the garage is overheated right now I will do no builds until I shift gear to the solar array.
