Hello,

Currently, I am living in at apartment complex.
I am trying to build 3 mining rigs in my apartment and have a question.

How can I connect all 3 mining rigs in my living room?
Can I use a same outlet? or should I spread out through out each outlet for all 3?

Thank you for your help.

What is the expected wattage of each of your rigs? The GPUs you will be using will play an important factor here. If you are running rigs less than 1000w at 220v sockets then you may be fine.

HOWEVER, you will need to know the maximum load your electric circuit is capable of handling. It is highly advised that you first consult with a real electrician.

What country are you in? How is your apartment wired as far circuits in say the living room (common U.S. practices are one maybe 2 different branch circuits in a livingroom and it all depends on when the place was built as to what size they are 15a/20a,  15a being the most common).

Dont let the numbers fool you.  Mining rigs are CONTINOUS DUTY and since that is so you will have to derate your branch circuits that they powered by.  The derating factor is 80%.  So a 15a circuit is ONLY good for 12a of continous duty! That is only 1440w at 120v and the includes ANYTHING that is powered on the same branch circuit also.

How do you plan on getting rid of the heat in your apartment during the summer? 

If I were you I would try to find out how many different lines (distinct circuits) you have in your apartment. I don't know your situation, but if you are in US you can add up the wattage in use on each. Wattage = volts * amps, and your lines in US would be 110 / 120 volts, at 15 or 20 amps.

Ex: there is a line that powers 3 light fixtures, and 2 receptacles. 110 volt, 15 amps = 1650 watts max. You want to stay less than 80% of that, so say 1200 ish to be safe. when your 3 lights are turned on they each use 100 watts so you have 1200 - 300 = 900 left to use on the receptacles of that line. If you have a rig of say 6*1060s running at 80 apiece, + a bit for cpu/mobo/fans on say an 850 watt psu, you are good. You don't want to use all of the psu capacity, leave lots of overhead there too.

That is just an example--but I and many others here would recommend a bit of time and research and running #s so you can run your rigs safely, as there've been some bad incidents lately in the news in apartment buildings. Good luck. There are some electicians on here who can weigh in too.

First do you have access to the circuit box?

If you do take a few photos and post them.

If you don’t have access to the box I would suggest you don’t mine with three large rigs.

Since you don’t know how much power you have available I would do one three card rig first.

I have 3 rigs (13 amd 570 on each rig) in my apartment (220v). They use 1500w each and is connected to each own circuit (bathroom, living room and kitchen). Main fuse is 40A. No problem using other household appliances.

Already a bad sign for mining. Apartment complexes normally are strained for power consumption as it is. There are many people sharing breakers and all sorts of unfortunate things that mean if you draw too much power you will blow a fuse or something.


Why have you decided that 3 rigs is what you are interesting in? You should start with one rig, as others have suggested, because you don't want to overwhelm yourself. At the very least you should do them one at a time, to make sure you are even able or willing to get them set-up and maintain them properly.


You will need to provide more information on the electrical situation. We don't know what kind of capabilities your outlets, fuses, breakers or how things are wired. I would imagine that using the same outlet will result in you blowing a fuse, given the information that you've provided so far.

Usually living apartments completed to use 10-15kWt.
You must know what are wire used in your appartment anc circuit scheme need for now how reallized outlets
to minimize problems connect each rig to different rooms

Have you considered your electricity costs? Regularly being in an apartment complex means that you pay a premium on top of whatever the electricity company is charging the apartment owner. Unless you have the electricity in your own name, but still; if your electricity costs are above something like 10-cents per KW/h then you have some big hurdles to overcome before mining is a feasible option.

Here is a list my rigs
1. 6x 1080ti (my place)
2. 2x 1070ti (parents house)
3. 6x 1080ti (future rig at my place)

I was thinking to put each rig on each room. (living room, bedroom, kitchen, etc)
Also I do an access to a circuit board in my bedroom. (I think they are either 15A or 20A when I checked last time)

I am paying about 9-10cents/KWH (living in 60440 US)
Thank you

OK, that's great and a start--but the crucial info, as Phillipma and others have pointed out, is a) how many different circuits in your apt, b) voltage and amperage of each and c) what else is drawing on those circuits.

In general the 1080tis are going to eat up a lot of power and take a big psu or 2 mediums--might be best to put the 2x1070ti at your place. Small psu, unless you've got its line overloaded with other stuff that is safest.

But again, take a bit of time and work out the #s, also heat/air flow etc., you will thank yourself in the long run.

What kind of PSU are you planning to use for those 1080ti rigs? It might be better to swap a few of those for the 1070's, because the 1080ti's use a ridiculous amount of power for a GPU. Sometimes putting them in separate rooms is simply not enough. Many rooms can be on the same breaker/circuit and this might prove to just be more work for no gain.


Since you are getting decent power cost, then it sounds like mining should be doable as long as the wiring and circuitry is done properly throughout your apartment. Do you have access to this information, the breakers or anything like that?

Most household 120V 15A wall sockets will get very warm when pulling over 1000W continously. Replacing the wall sockets with 20A sockets keeps them from heating up.

this is not always true.

in usa
14 ga  wire can be in circuits
12 ga  wire is pretty good
10 ga  wire is no wqrries.


if he has some 14 ga wire in his apartment  and puts a 20 amp circuit breaker he can do a fire in the wall.
.
another problem is aluminum wire.   rare but if the building was built from 1965 to 1975 some areas allowed it to be put in due to copper shortage ( Vietnam war ).

Aluminum  is shitty compared to copper and in a house really shitty.

I know this because my home in NJ  had aluminum wire.
I fully wired my home with copper in the 90's I put in a lot of heavy duty wire for amps to run subwoofers ,lucky as my house now has 2x 30 amp 240 volt circuits for mining.  and only 1 subwoofers for HT

The reason most household 15A sockets heat up is because they are cheap and not meant to carry a continous high amp draw, even if the wiring is the correct gauge for the load. Replacing the socket with a higher amp socket solves the problem. It obviously dosen't change the capacity of the circuit though, so if it's 15A circuit, putting a 20A socket won't change that. If you have aluminum wiring, then you also need a socket that's compatible with that as most sockets are made for standard copper wiring.

This is exactly what happened to my father's garage. Poorly set-up and designed wiring and circuitry, mixed with time is not a good outcome. You are bound to create a fire if you are unaware of what you are doing down to the precise measurement. You need to know how much power you're pulling, what temperatures everything is operating at and what the complications of each moving piece could possibly be.

If you are only planning on doing one rig now and another rig in the future, then why are you asking about putting three rigs into a single apartment? It sounds like one of them will be left at your parent's house, another is down the road in the future and so the only consideration that needs to be thought through at this point is the single rig that you plan on doing now. By the time you get to the other rig(s), there may be a lot that changes.

Here is my circuit breaker setup. https://imgur.com/hbkDDsM
I just cheked my kill-a-amp and it is drawing 10A from this outlet. Nothing else is connected to this outlet.
I think this line is connected all living room outlets. And I connected only my modem,TV, and sound system. (I watch TV really rarely)
Thank you

With as many breakers as you have, it shouldn't be a problem to run 3 rigs across different breakers. To find out exactly which outlets are controlled by each breaker just flip the breaker off and plug in a lamp around the different outlets to determine which outlets are controlled by that breaker. Do that for all the outlets that you plan to use for rigs. Then spread the rigs across different breakers to keep the TOTAL draw of all the outlets on that breaker to less than 80% MAX, so for a 15A circuit no more than 1300W TOTAL.

Thank you for all information.

I started to mining about 2 month ago. (I know that I started late)
This is one of my hobby and trying to get out a decent amount from these rigs. This is why I purchased many cards and running current setup.

I will try to spread out though out entire my space and run rigs safely.
Thank you all..

Can confirm. Electrician.

I think better you use different socket. I am worry if you use 1 socket with 3 rig it wil be burn. What my experience, i use 1 rig to 1 socket with 15 amp. So i separating 1 socket to 4 socket for my 4 rigs.

modern LED lights only use 7 to 10 watts each. even the older spiral bulbs are maybe 20w. no one uses incandescent in the US anymore

best thing for someone to do is measure with a kill a watt then calculate what else is on the line. my advice is turn off a breaker you plan on using and see what else dies. if it's just lights. 100w is like 10 lightbulbs which means the rig could have a max draw of 1200-1300w to stay at 80%
