the 16 card had a special back plane and run not stop in a 95f room for 5 weeks zero issues rock solid gear.
Just not that efficient.
a 19 card build with carefully tweaked risers would be better power wise, but if all 1080ti's it would be hard to power or cool.
it would pull over 3000 watts more like 3500. It would need 2 delta 2400 watt plus'
We are talking about the 19-GPU motherboard that is ASUS B250 Mining Expert right?
How do you figure that it would be hard to power 13pcs of 1080ti and 6pcs of p102 mining GPUs? I am of the impression that the ASUS B250 already has built-in ATX adapters capable of supporting up to 3 PSUs. Do motherboards have a maximum electrical load or are problematic with high powered rigs? I've only mostly run 1070s and 470s in the past.
okay 19 cards 1080ti = 19 cables for the risers 38 cables for the cards or 57 cables. the closest to that using atx would be 3 corsair ax1500i they have 9 2x cables = 18 so three of them = 54 cables and $$$. and 4500 watts max
If you went with 2 delta 2400 watts (very hard too find) and the better break outs
you can do 4 of them or 64 cables this would work. but the delta 2400 is hard to find you could use other hp power supplies
