Downtime is your biggest hidden cost. Don't expect it to be running smoothly 24/7, never happens.

Great tool, using on my all rigs, gets rid of so much hassle and especially problem when rigs crash midnight and are offline till morning when you can notice it.
Would be great if you would integrate one more option - restart on loss of internet. I currently have script running that does that, but would be nice to have such option inside this tool. And possibility to have rigs named when sending emails otherwise cant know what rig have been restarted and having problems.

This is quite funny to be fair. You got money, someone told you that you will make shit loads doing nothing and you bought in without realising that mining is far from doing nothing. I would strongly advise you to spend those 3 month studying about mining, about electricity, data centre cooling, static pressure etc as mining isnt just plug in and leave and watch how money rolles into your bank account and be prepared for massive down times, spending days on trying to figure out what is not working and why and etc ... really ... get yourself informed and educated on technicals or you will burn out your 50k work of investment.

I use ATX power connector, connects ATXs cables from both PSU and goes into motherboard. So yeah, it just takes 2 pins and joins them together.

I do agree with you but you mention you have 8gpu on 1000w is something I would like to learn from you. Do you mind sharing the cabling diagram or a pic would do.
I have a plat 1000w with 8 x 8pin but I am worried to push it.
There is nothing special about it, just connect everything together. Only thing, I am using gtx 1070 with lowered power limit, so they consume only 100-110W. |

As most altcoin algorithms are memory heavy, ASICs would not be faster then GPUs as memory speed would bottleneck device as ASICs and GPUs use same memory. Only gain from ASICs would be fact, that they would be more power efficient, but impact on mining would not be as near as close as it was when BTC went from GPUs to ASICs when we say massive increase in performance and massive drop on power usage at same time. And that is biggest reason why there are non and most likely wont be one in near future.

Then its just cheap connectors. Try to take them to some PC repair and ask them to re-solder you new connectors.

Nothing to do with PSU it self nothing to do with how much current system draws. You can produce flame with AA battery as well.
Looks like just faulty soldering or faulty connectors. Loss of proper connection causes open circuit > resistance closing to infinity thus current without other path will try to flow trough and heat up at point where resistance is high causing connections to catch fire. Might as well be just your own fault if you did not connect wires properly but I would go with cheap connectors used that doesn't fit together too well.

First of all, 1300w PSU would be sufficient if you have enough cables. Buying expensive PSU - pointless, buying oversized PSU - pointless. You have to take into consideration only 2 things. Your system power draw is around 100% of PSU power rating or below and PSU is gold rated or above. That is it.
All those comments - get expensive PSU, get 2x1000w or what ever other wattage PSU are complete BS and are factless. Period. I got couple of 8 gpus (gtx 1070) rigs running with SINGLE 1000w gold rated PSU! Stable! First of all, to all people giving those random things like unstable, reduced lifetime etc I would suggest go and study little bit of structure of PSU and how they work.
Most of normal PSU have 5 or more year warranty, meaning you can run them straight at 100% load of at least 5 years! End of the story.
One I am using is Enermax Revolution 87+ 1000W PSU that have 4 12V 30A power rails. Quick calculation P=IV=1440W + sata cables that supply part of power to GPUs trough powered risers are on different rail thus there is even more total wattage supplied by PSU. And that is just amount it have to reach to have Over Current Protection (OCP) kick in. This is reason I would suggest using multi rail PSU if you require more then 500-650W - extra safety as if you have everything on one rail that have OCP, lets say 100A, then most of your equipment will burn out until OCP trips and switches off PSU.
Most of PSU manufacturers will state total wattage produced from 12V rail while there are 5V and 3.3V rails that supply mobo, sata, etc that are not included and alone are extra 100-150W.
Oh and in all my years working as electronics engineer, we design things capable of working way above values specified to customers!
Currently I am building 8 GPU rigs with 2x750W Chieftec gold rated PSU just because it cost less then getting single 1000w-1300w.

Yes, you will make around 30 euro profit on that.

I have a plan to build zcash mining rig with 6x 1080Ti on same motherboard and 2 powersupplies (2x 1300w). will it be stable for mining?
Yes, if you don't overclock too much. And 2x1000w power supplies will suffice for 6 cards. With 2x1300w you can get 8 cards running there for good option if you want to upgrade later. |

And? It does not say how many GPUs and it does give that only for ETH mining that have different algorithm so different amount of data received and sent to network. + by context he talks about GPU not GPUs and gives number of 150MB per 14 days so 300MB for GPU per month. That is year ago and does not specify what kind of GPU that is. So my statistics are quite close if my GPU requires 350MB per month as it might be faster then common GPU a year ago. All your arguments are silly and does not hold if you analyse them so do not go and say my statistics are wrong. That is average from multiple rigs mining ZCash and it is in range of 340-360MB per card. You give random numbers from random post a year ago "answered Apr 17 '16 at 22:18" I gave specific number stating specific conditions from past month. |

This thread if for EWBF miner not PSU discussion, but answering some replies about PSU.
No, it is NOT dependant of manufacturer of PSU if you can attach 4 GPUs to it or not.
It is dependant only on two things - firstly - does your PSU can produce required wattage for your system? As rule of thumb good way to look at it is that system itself will draw around 100w so rest is left solely for your GPUs, so you looking around 650W for GPUs. For 4 cards that's 162.5W per card. You could easy run slightly under-clocked GTX 1080 with that or GTX 1070 with maximum possible OC. So in your case you could even go with smaller PSU, but most PSU bellow 750 don't have more then 4 PCI-E power cables and that's your second limitations - number of cables.
Im running 8 GTX 1070 with 1000w PSU with ease and stable.
wow nice mining rig. im only familliar with amd cards bios mod and oc etc. how do you oc 1070's for mining? bump up the memory clock then lessen the core clock and target voltage? or do i just bump up the memory clock? I increase base clock and memory clock and decrease voltage. gtx 1070 with EWBF miner gets me 420-425sol/s and draws 115-117W per card. hmmm i thought you cant decrease voltage in nvidia 10 series. what i do is just set the power target limit to 80% That pretty much translates into decreasing voltage. |

Miner only with 6 GPUs - 2.2GB per month, 8 GPUs 2.7GB per month.
not really, the more miners you have wont increase 500mb consumption by adding 2 more. if 6 using 2.2gb it dont add upp. This question was answered years ago, the consumption is not eqal to how much machines you have, t he soncumption will mostly depend on the connection . But around and no more than 3gb should it be montly if yo uare using LTE or 3g.. Makes no sense. More GPUs you have, more task you will get, more answers you will send back thus - more data per second. Each GPU work in parallel with others not series. Same as rigs, each rig works in parallel with other rigs, not in series. the machines are not working on a web, so they are not working on the network, they work alone , by the multiple cpus they got, the only data that goes out is hash information. , and besides a person whit 3 posts and explaining wrong stuff, when as said this question has been asked and aswered many times , by LEgendarie members and not a newbie whit 3 posts. And as said , your calculations dont add upp. i have 10 machines running, they bearly get to 2gb montly. and i guuess most of community can cornfirm this as all miners have control and watch over their mines statistically and economicaly. It all depends on what kind of GPU you have and how much of them you have. Currently my rigs with GTX 1070 consumes around 350-360MB per month per card (upload/download) solely by miner. And yes, calculations are done locally, but from server you get tasks to solve and send back your answers. So data consumption is proportional to speed your GPUs work at and what kind of algorithm they use. Faster you GPU makes calculations more tasks it will receive and more answers it will send. My numbers are for ZCash only. And what does it have to do with post number? That is not an argument. The argument is that this has been answered already by alot of members. ou are giving out wrong information. I gave my statistics under my conditions. As mentioned above, there are lot of variables, that affect that. And wrong? I told my 6gpu rig gets 2.2GB data per month, you said less then 3GB ... I guess with variations between GPUs/algorithms that is around the same. |

No. You want them all at 1x. That way your CPU has more lanes available for more cards.
Why does it have more lanes? Can i plug more riser cable at a same slot? No that is not what he meant. He meant that each slot on the mother board is connected to CPU. CPU have limited number of slots you can connect to them. Basically, answer to your question is NO and extra comment given by him does not really concern you. |

The number of slots on a motherboard doesn't mean they will all work with GPU's and risers. That;s why it's important to stick with motherboards that are known to support 6+ cards.
A single reason it wont? |
