The APW3++ is supposed to be rated for 1200w on 110v. You can't run 3 minis on 1 APW without 6 pin splitters which I believe you're not supposed to do. However I am going to try to run 5 of them on 2 of these PSUs
The mini draws like 350W overclocked. You can likely run three of them on one APW3++ (though it's rated for only 1000W @110, I've never had a problem going over with any of mine--not suggesting others do it, just saying).
The APW3++ is rated for 1200W on 110v. You can't run 3 minis on a single APW unless you use 6 pin splitters which I believe you're not supposed to do. However I am going to try running 5 of them on 2 of these PSUs
Never use pin splitters. If you switch to 220, you can add more cables if you want, but splitting limits you to the max output of each cable, not the overall psu. And yeah, you're right, I forgot there are only 10 cables. You'd have to add more.
It depends which/when you bought. Bitmain's current APW listing says 1000 @ 110. All of mine were rated 1200W, I was just being conservative in the examples.
