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 ...

Its a mixed GPU rig: 4 msi 4g 470s at 27.5mh, one 370, one 380, and a 1070.
