as i said AT THE MOMENT OF WRITING , stongest card providing HIGHER HASH RATE (no matter the power consumption) is RADEON PRO DUO ... 900 to 1100 hashes /s depending on the oc you apply ... of course the higher the hash rates the more inefficient it is... at 900 hashes is a bit less efficient than nvidia cards (4.5 w for each hash)
Per that number the TI only uses 156 w per hash?The 1080 Ti can be set to do ~600 sols at ~150-155 watts. About 3.9 hash per watt ratio. You can get it up around 700 sols or higher but it will use the full 250 watts and beyond, making it very inefficient if you run it that way.
so running 6x 1080ti should be possible with a 1200W psu?
If you had the requisite 12 PCIE connectors on that PSU and you made sure to reduce the power limit on each GPU before you start to mine you might be ok. 150 watts per GPu is 900 watts, depending on the rest of your hardware you could have anywhere from 50-200 watts added onto that. When you take into account your PSU's efficiency rating you will be pulling anywhere from 1050 to 1220+ watts from the wall and you should never load your PSU to the 100% max... 80% is the most I like to do myself. You will burn out your hardware allot faster if you stress it too much.
