Title: How do people have 20 mining rigs setup in 1 room without blowing a fuse?
Post by: bbitcoin on March 18, 2012, 10:39:08 PM
I've seen people have like 20 or more mining rigs set up in one room? how is that possible. Each outlet can handle only 15-20 amps. You can't even put 2 mining rigs into 1 outlet or its going to blow a fuse.

Don't put them all on the same circuit?

I run a 200 amp 208v three phase service.  ;)

a 20 amp outlet can handle two rigs, just not the biggest rigs.   But power is only half the battle, cooling is the other half and that gets pretty tough even on the commercial level.

Install more/bigger outlets.

My rigs never go hungry with these outlets. I run 4 rigs per outlet.

Hint #1: There is no such thing as "the outlet".  
Hint #2: Most homes have NEMA 5-15 outlets.
Hint #3: NEMA 5-15 is a max of 1800W (1440 for continual loads) but there are other kinds of outlets and you can install more than 1.

Just finished wiring my basement for 8 more 220v outlets on a 6ga wire to a 40a breaker.  My fingers are raw... fuck you 6ga wire and your stiffness!

Actually, I think it was the feeder 12ga wires that did the most damage to my precious little digits.

Yup I hate working with 12ga; it's amazing how much easier 14ga is to work with.  Unfortunately I ran out of 14ga years ago but have plenty of 12ga left and I'm too cheap a sumbitch to buy more.  8)

you run alot of copper...

2x 10/3
1x 10/2
1x 12/3

The quick and dirty way to run a bunch of rigs in one room is to run extension cords through a closet or up/down stairs from outlets connected to other circuits.  This was the only way I could run five rigs in my house without exceeding the angry wife threshold.  Of course, if you own your house, you can put in larger circuits and stuff.  I wish I had that option.

This is how solo miner 88.6.216.9 does it.

110v is for kids. My desklamp, phonecharger, alarmclock runs on 240v. Bladesaw, boiler and weldingmachine on 3-phase 380v.

Hi, I upgraded my mining appliance and using 100gw of atmospheric energy now.
How do people deal with winds created by the thermal chimney effect, can you build structures strong enough???


Everybody has different problems ;D

110v is for kids. My desklamp, phonecharger, alarmclock runs on 240v. Bladesaw, boiler and weldingmachine on 3-phase 380v.
How much did it cost to have a 380v installed?


Title: Re: How do people have 20 mining rigs setup in 1 room without blowing a fuse?
Post by: ElectricMucus on March 24, 2012, 11:48:03 AM
That's just dependent on where you live, plus 240V would be equal to 415V 3-phase (times the square root of 3).

It doesn't make any tremendous difference though, anybody needing huge amounts of power would need their own transformers anyway.
The thing is you can run 3*3600W ~ 10KW off a standard household wiring (for 110V it should be half with the same wiring) , for anything more you need thicker wiring and stronger fuses. And the electrical supplier would gladly supply you with another circuit if you use that much.
People actually doing this you can probably count with a few fingers.

The heater, dryer, stove, AC has large 208V going into them. One could build a circuit to supply power to either the appliance or your rigs; just make sure they aren't drawing current all at once.

Notice that not one person has mentioned solar or wind power?

I have been thinking about solar powered FPGA rigs, but it's so huge one-time investment that I would need a loan.

Solar or wind power has nothing to do with blowing a fuse.

that is because solar power would NEVER work. At least not with current existing technologies.

What do you mean it would never work?  You may not power 100% of your rigs from just your PV array, but you offset as much as you can.  We are installing 33 panels that total to 7.6kW.  We have one bitcoin mining rig that takes ~600W and a whole bunch of TV's and other electronics.  During the day a percentage of our total power draw is going to come from the panels, during the night we should be backfeeding (selling) a significant amount back to the grid.  Explain to me how that doesn't work?  Scale it up to tons of bitcoin mining rigs, say you even had 8kW of rigs...you are still offsetting the cost with the array.

I would really like to see the Break Even Analysis on 33 Panels and mining.

How long until the break even point?

Anything over 5 years is a no go for anything.



Title: Re: How do people have 20 mining rigs setup in 1 room without blowing a fuse?
Post by: DeathAndTaxes on March 31, 2012, 09:08:49 PM
Why would the break even analysis be different for mining than anything else?  A kWh is a kWh.  It isn't like mining uses special mining kWhs.

Depending on where you live like it or not there can be MASSIVE subsidies for solar.  All that matter is which is cheaper over the life of the system solar or power company.  In CA between federal subsidies, federal tax credits, state tax credits, real estate tax exemption, and more cash out of pocket can be less than 1/3rd of retail.

Still solar is irrelivent to the thread.  Regardless of you you get your power (solar, power grid, 100 prisoners on excercise bikes) the issue of how to distribute power remains the same.

Just finished wiring my basement for 8 more 220v outlets on a 6ga wire to a 40a breaker.  My fingers are raw... fuck you 6ga wire and your stiffness!

Actually, I think it was the feeder 12ga wires that did the most damage to my precious little digits.


With that kind of power usage, they'll think you are operating a weed farm.

Well the traditional cost benefit is the cost of the GPU, Mobo, etc... and the cost of kWh.

The cost of a kWh from Solar will have to be judged from the Cost of the Solar Panels and electronics required to provide the power necessary to run a mining Rig/Farm. How long will that Farm have to run until it pays for the Solar Panels and Electronics required?

But yes, a kWh is a kWh.

extension cords?

i use power from 3 rooms

just make sure you get a good extension cord
