You COULD also, if you're not using the outlet at all, install a breaker box and run 110 lines out of it. On a 40a 220 line you should be able to run 3-4 20a 110 lines safely. If you don't feel comfortable doing that DIY, hire an electrician.
That sounds asinine. Why the fuck would you do that? Not saying that you can't do it, but why would you? You can run double the rigs at the same wattage on 240 as opposed to 120, because the amp draw is exactly 1/2, but you're ruling out the overload protection and equal distribution per outlet that a pdu will provide ... And better efficiency at 208/220/240. Efficiency to a degree is valid, yes, though in my house I've noticed an extremely negligible difference when testing antminer PSUs (though they are SUPPOSED to have significant efficiency variance). Draw? 4x120=480W. 2x240=480W. How are you running double the rigs on the same wattage? You're able to run more on less amp draw with 240. Not more wattage. Maybe I said that wrong. If you have 100amp service, that's your limit. If you have 200amp service, that's your limit ... |

The problem is you are cashing out and not holding till market value comes up. Hold and that 2 dollars today 30 days from now maybe worth 6 dollars. Mining is not a get rich quick unless you hit the jackpot mining a coin with no value that goes to the moon. Just my 2 cents.
Exactly ... And it is moronic to track daily in fiat value even if you are not cashing out daily. The exchange rate to fiat is constantly changing. Some people cash out frequently to convert to fiat to pay their electric bills..... I cash out 3-4 times per month just for that reason. Or once per month if the prices are good. Well I can understand that but you can't complain if you cash out you have to live with that choice. Everyones circumstance is different but in the end we all have to be satisfied in our choices in the end. Do you pay your electric bill 3-4 times a month? I pay mine once a month. Just front it with your other money and cash out for a few months of electricity when it's good to do it. If anyone thinks this is a short term thing, they are dreaming. Nope once per month, but I cash out depending on the ebb and flow of the price of coins. If you cash out 1 day then you might not be cashing out at the most optimum time. I do it as I go along. a $320 electric bill each month isn't difficult to pay for with the least amount of coin if you time it correctly once a week. As someone else said i guess ... Everyones situation is different ... I have a full time job, so paying to power my small 24 gpu mining operation out of regular income isn't that big of a deal, until I feel that it's worth cashing out a bit for electricity costs. I just wouldn't do it multiple times a month over the past a 6 weeks. |

Mining is no longer profitable for home miners, unfortunately decentralized technology became centralized due to interests of these who hold 99% of the riches. Basically same story than our banks, within 1 year only...
True that ... Can I buy your gpu's really cheap? Lol. I don't care how old they are, I will give you 40 cents each plus shipping. |

hmmm, why not just buy a less expensive card that mines more per day. I'm still getting $2.25 per day with my 570's that only cost me $200 over a month ago only drawing 88 watts each. They seem to always be in stock.
for now im just mining shit coins in hope they blow up, but every single coin started out as a shit coin, even bit coin nobody took serious. when the does price of these GPU go down? You're mining with 2 gpu's? I mean come on ... Expect some little profits if you do it right, but don't expect your Lambo in six months ... Lol. |

Never heard of this before. Build bigger rigs. Don't have small rigs. I honestly don't think it makes any difference. Difference is in the hardware even if they are the exact same model. Did you think of the other variables that you haven't thought about yet?
Main difference is if one goes down, you still have others mining while you fix it. But yeah, if you trust your gear, you're only saving a little bit of electricity (for my three rigs, combining would probably save 80W) by combining. Switched PDU solves that problem. |

Profitability has dropped some the last couple weeks, combination of folks adding some new rigs and coin prices dropping from their peaks.
Still not down to where it was at one year ago.
I'm hopeful that we haven't hit the bottom yet. I have orders in that need to be filled ... Lol. Crossing my fingers for 7500-8000 btc price in the near future. |

When I compare the ratio of worked performed and accepted shares on my smaller machines compared to my larger ones - the pool seems to sometimes drown out the smaller machines. A small starving machine with barely any data to process suffers doing nothing but wasting electric. My idea would be to combine my work into one large loaded stream, to make efficient use of all my machines and not just the largest and fastest. There are other advantages as well.

Certainly don't just buy a "adapter" and use a standard surge protector with it, because the plug fits. Standard surge protectors are rated at 15A, in the USA at least. ... You're talking multiple rigs anyway, right? So you're going to want a PDU. Spend the money on it, before you blow everything up.
And as we've seen in this very thread ... Electricians don't know everything.
I'm planning to buy this adapter : https://www.amazon.ca/Conntek-P1450650-Generator-250-Volt-Adapter/dp/B00SSQIYLUand a 40 amp PDU to distribute the power and not blow anything up lol I'll be using around 3500+Watts. I'll talk with an electrician just in case... thanks for your help. That isn't the proper female plug for a 240V PDU. Most 240V PDUs have a L6-30P. If you goto Lowes or Home Depot you can buy the parts needed to make an adapter. So I guess something like this will be suitable for the PDU: https://www.amazon.ca/Conntek-Electric-Vehicle-Pigtail-Adapter/dp/B074SFKZN9And the PDU will look like this: https://www.amazon.ca/Tripp-Lite-PDUMV30HV-Metered-Vertical/dp/B0012VN0I0Also, I've noticed that there is no 40 amp PDU... So If I use and 240V 30Amp PDU, I won't be able to go over 5760Watts (240V * 30Amp * 0.80%), even if my circuit allows me to have a little more, right? Please correct me if I'm wrong. I have one of those Tripp Lite PDU's that you linked to sitting in my closet. That was the first pdu that I ever used. Recently swapped them out for switched pdu's, so I could shut off, turn on, cycle power on individual pdu outlets remotely, but that will work and it displays amp draw. Huge plus. I would still have the breaker replaced with a 30A and it would probably be cheaper to have the outlet replaced so you can plug the l6-30p directly in, rather than buying that adapter. |

If you goto Lowes or Home Depot you can buy the parts needed to make an adapter. Better yet. Have the outlet replaced by someone who knows what they are doing, before plugging a pdu or any adapter into it. And have them inspect the wiring to the breaker box as well. I think my electrician used 8 romex, can't remember for sure. Don't 40A pdu's exist? I have no clue, because I use 30A breakers for the L6 outlets in my mining room that each pdu is connected to. Each outlet has a 30A pdu on it that can power up to six of my 6 gpu rigs. And if you don't know this already ... Don't use more than 80% capacity. Bottom line is ... Don't fuck with electricity, if you don't know what you're doing. At best, you'll kill your rigs, at worst you'll burn your house down. |

You're going to use that and then try to plug a fucking surge protector into it for more outlets? |

Buy a 220V surge protector and 220V cords for your PSUs (assuming they can handle 220V, I've only ever used 220 with Bitmain PSUs, but I assume it's doable). You'll have multiple 220 outlets and up to around 7KW to play with (provided the surge protector can handle that much).
OMG, NO! |

i think you should familiarize with your amperage of each wall connectors. Mine is older condo and it appears all the sets of wall distributed around 2bedroom is controlled by 2 major circuit breaker. One time I tripped the circuit breaker and half of my miner lost power. Using that chance I decided to tinker with the patch panel to found out which switch will enable/disable which electrical items. There are separate breakers for lighting, walls sockets, dryer, kitchnen washer and dryer and I think I identified most of it. And each of them has marking of max amperage.
I've checked already by running test with the breaker and turning off and on the breakers to see witch rooms/outlets are affected. My basement is very small and the picture I posted shows 40amp 240V for that circuit (witch is used for my stove only). Certainly don't just buy a "adapter" and use a standard surge protector with it, because the plug fits. Standard surge protectors are rated at 15A, in the USA at least. ...

My 1070 struggle to make $3 a day
They want $999 for a 1070 I just spent less (780€) for ten 1080 Ti, you should search for better deals. He has no idea what he is talking about and he doesn't know the difference between a legit retailer and a reseller selling on a legit retailers website like NewEgg, Amazon, ect. |

but the card prices keep going up....
and no dont tell me bitcoin is down, its still $10,000 a coin!!!
Ohhhhhhhhhhhhhh noooooooooooooo!!! The sky is falling!!!!!!! Run while you still can!!!!! Lol. Card prices aren't up that much from MSRP with legit retailers. Problem is legit retailers don't have stock. So you wait! Simple as that. Not sure how many times I have to tell you this. It's becoming a daily thing I think. You don't know the difference between a legit retailer and a reseller. See your other thread where I explained it to you. |

Is he really going to unplug this stove/oven and put mining rigs in his kitchen? To each their own I suppose ... Lol. Mining is getting crazy.

I’m an electrician. It’s defintiely doable. Just get the right cord which plugs in to your oven receptacle and then the correct adapters for you PSUs and you should be good.
As in a 40A 240V PDU? Since I’ve never done it myself, I can only guess yes. The oven plug is 240V 40A so that would make sense. However, I would suggest get an electrician over to double check before flipping on the switch. You pay for my flight there and I’ll gladly come check it out for you.  I'm not the OP. Just thought you'd know a little more since you're an electrician. I personally run rigs off of two 30A 240V circuits. I have a pdu on each of them which provides enough outlets for multiple rigs. You'll find pdu's in any data center. You can get metered ones that display the amp draw on each bank and you can even get switched ones that will allow you to turn any of the outlets off and on remotely. The big thing is that it provides evenly distributed power over all outlets and provides overload protection. So my question to you since you're an electrician ... The adapter that he linked to above is not going to provide any overload protection, right? Is there a possibility that he is going to harm his equipment by just using an adapter like that? I personally would never use something like that for this application. |
