That picture looks awesome !!!! I will do it that way, - riser "problem" solved Thanks!  What about the PSU? Please correct me if i am wrong but as i understood it: 1 x 1080 ti = 250 Watt stock 6 x 1080 ti stock = 1500 Watt + System power = Way more Watt than Corsair HX Series HX1200 or even EVGA SuperNOVA G2 1300W. So whats an option here? To be honest i also did not understand rather i should underclock/volt my GPUs 1080TI or not? Even if i undervolt them to lets say 150W, i would still be almost at Max power / PSU. (I am not sure if it is a good idea that PSU is at Max power capacity) Other question is that i heared that if my rig has 6-10 GPUs i might get much more problems running it correctly. (Hashrate gets low, or i get Driver problems, and so on. Is it true? Would i get less problems overall with 2-3 GPUs? |

We have a rig with 6x GTX 1080 Ti GPUs - running at 62% power the watts at the wall are ~1025, with an average hashrate of 580 on Zcash via NiceHash miner. --- I have a GTX 1080 Ti in my personal computer that does ~615 hashrate on Zcash with the EWFB miner at the same 62% power limit. |

Hi all! to be honest, i dont get it aswell  Why invest in 6 x 1080 TI but only use 60% of it? Is it really smart? If i am still going with 6 x 1080TI , how can i make them run? Would need 2 x PSU than? How do connect them? |

Would need 2 x PSU than? How do connect them? you can buy 1 corsair ax 1500i, should be more than enough for 6 1080ti, even if you run them at 100%, but i suggest 80%, the gain is minimal over 80% not worth it, just overclock the core to get more hash |

I am not 100% sure if i am gonna use 250w or undervolt but looks close to the limits. (i also dont know how much Watts all the other hardware uses) Maybe a EVGA SuperNOVA G2 1600 1600W 331€? or 2 x psu at 900w? |

In the near future that rig will be in a separate building where the possibility of using server PSUs will allow us to run them at the full 250 watts each if need be. The server PSUs are too loud to use in the house where the rig is right now. |

Hi!
Well i think i will go EVGA G2 1600W and just pray that i will be enough power.
