I would offer $9300 for the lot if your interested. I live in Olathe, so we can pick up the units, but would you potentially be available to help set them up if we make a deal, we could include an extra charge for the assistance with smOS and cabling set up? I have not worked with multiple PSU's per rig before, so I want to make sure there won't be any issues and we can get setup and running with no problems.
just make sure you power the cards before the computer...
similar to an antminer on multiple psu's
I usually run the risers on the psu hooked up to the motherboard.
If you run multiple high power cards per sata connector it might fry them... <--old amd cards are bad at this... newer nvidia not so much.
