Also... your going to need 3 separate circuits to run those off of, presuming you have them plugged in 15Amp ones. At 1200W/120V each will be pulling 10amps, well under the 12amps a 15amp circuit can handle continuously, but no way to combine (3) power supplies onto (2) 15amp circuits and not pop a breaker.
Hmmm, each miner is going to pull something like 1422 watts, so roughly 475 watts per hash card (not accurate since I split the controller power across all three cards, but close enough). So your at 950W/120V or 7.9 amps per power supply. So no... still can't run two on a 15 amp circuit, although your right on the edge for running two on a dedicated 20 amp circuit (rather depends on how efficient your power supplies are, and if your getting 115V, 120V, or more at your socket).
Topic: Can I use 3 x APW++3s to power 2 x S9s? (Read 145 times)
Thanks guys.
I assume in the case of the "wrong" PSU failure my S9s might be damaged?

^^^ Yup, that would be a possible 'gotcha' 
Remember to power up the PSU running the controller last
That should work fine. Only caveat, which you have done correctly, is to never power a board with more than 1 PSU. I use multiple PSU's on my miners all the time for cost and eff reasons.
Mine On!
Mine On!
Stuck on 120V here, looking for powering solutions.
The APW3++ gives 1200W. Any reason I can't power two hashcards on one S9 from one, another two on the other S9 from a second, and both remaining cards (one one each S9) plus the two controllers from a third?
Powerwise it works. Any gotchas I haven't considered?
