things are getting moving along for the shed build out.

met with the Electrician and his Journey man again last night for 1 final walk through for a complete bid.

I got approval from the boss lady to finance 4 new rigs as long as I do it as cheap as possible to get quickest ROI.

Coins can only be cashed out to pay for Equipment and Electricity and a itemized list of components for each rig must be provided. So easy stuff so far...

I am in the process of searching for 24 graphic cards (that's the budget for right now). Prefer 4gb unless I can get the 8gb for around the same costs. I pull the same hash rate from my RX570 4GB cards as I do my RX 570 8GB cards just better wattage.

We will continue to expand, but if I can get 24 cards for average cost of 250 I can have some extra funds for the hick ups that always happen.

If anyone has any tips on helping make this as cheap as possible let me know. I'm building 4 rigs with these components:

1x2 wood frame for each moving-$5
HP1200watt server PSU-$43.99
Evga 400watt PSU-$40
DDR4 288pin 4gb RAM-$53
Asus h27- Prime AR Motherboard-$101
SSD 60GB-$35
CPU-$55
Risers 6pack-$40

GPUs--unknown as of now

electrician came out last night and looked things over.

House is 200amps total but he estimated that we are using maybe 35% of that for the 2400sqft house.

I do have a dedicated 50amp breaker for a hot tub that was removed before we bought the home.

He gave me 2 options:

1. He said he could run a line from the 50amp to the shed since that is in the  main box already and that would give be enough for 8 rights. 11,000 watts total but wanted to keep it under 80% so I figured 8 rigs plus fans, network switch, overhead light, outside light at entrance, video security and monitors to view or troubleshoot each rig.

2. Run a 150amp subpanel from the main panel and have all new wiring, conduit, and run Ethernet easier that way also since we would be going from the house.

Bid should be coming in via email today or tomorrow. another electrician is wanting to come out for a bid today but I will be at work and cant leave so its frustrating.

Option 2 seems best! A 150A subpanel would give you 120A dedicated to the shed. If you are only using 35% of the 200A, that equates to 70A. 70A + 120A=190A. You are under your 200A main, but you are over the whole 160A target for continuous load. However, you will not pulling the 70A continuously. This is when you are running AC, doing laundry, microwave, etc all at the same time.

So... seems good!

thanks for following up. if I can post pics on here easier I would. I know this shows my profile as a newbie but I recently changed usernames so im not 100% retarded when it comes to mining but at the same time im definitely not 100% an expert.

this is going to be a BIG journey for me but so far I am not disappointed with my 2 Rigs.

I will be having "the talk" with my wife tonight if its a good time to borrow and build out 5-6 rigs once the shed has the electric.

I will respond to only one part : aim for as many 230v line you can.
It will save you electricityand you can pull more from PSU with 230v than with 110v

A shed buildout, my kind of project! Here is mine: https://bitcointalksearch.org/topic/55gh-eth-man-mining-shed-needs-de-humidification-please-provide-suggestions-2373161

If you have a 200A panel that really means you are only able to run 160A (200*80%). You have to leave some reserve for the house AC, Washer, Drier, Hot tub, (all high amerage items) etc. 200A is overkill actually. My home had a 100A panel, so we upgraded to 400A service and a dedicated 225A feed to the shed.

If you have the capacity, I would run 2-3 30A 220V circuits. Don't worry about the existing circuits because you are not using all that power. I don't think you need a dedicated sub-panel, but that is up to them. If you are going to spend the money, get as much ran out there as possible.

Questions I wanna know before I ask someone in person:
1. If my panel is only 200amp, can we reduce any amps for the bedrooms to give more Amps for the shed?

You have 200 total, entire house draw and draw per breaker different things.

2. Can we add a brand new 200amp box just dedicated for the shed but would be billed on the same electric bill monthly? (might be a eclectic company question)

You CAN add a 200A sub, but you need to understand MAX house draw and how much are you pulling so you can be sure not to overload your Main

3. Can I put the electrical wiring and the Ethernet wiring in the same trench or run them on the fence line to the shed to save from not digging? (Shed is approx. 170ft away from panel)

You can, some electricians will tell you there might be feedback/talkback/chatter whatever it's called usually there's a min distance so up to you really I haven't noticed any I ran an Ethernet on my 220 line no issues.

any possible ideas, or other things to think about please let me know. I don't want to spend $1000-$2000 just installing electric when there might be better ways




Thanks for the answers. When I lookat my main breaker switch (like if I turn it off it will turn everything off in the house) it says 200amps.

all my individual breakers are set at 20amps except for the 50amp breaker for the hot tub and I wanna say there was another 50 amp for the range in the kitchen. I wish I had time for an electrician to come and look and give a bid. working 8-6pm daily sucks when that's when all the electricians wanna go home.

****I did create a new username because the last one was not the best and I could not change it. This is not my first post.****


As tax return season is coming quickly (for most people with typical jobs) my wife and I have decide to pull the trigger and run electricity to the shed in the backyard and start scaling our mining operation up.

We currently have a free 50amp breaker from a hot tub that was removed before purchasing the home. The house is set up for 200amps total base on the main switch I see on the Electrical Panel in the garage.

We are in the process of getting bids to run a sub panel to the shed for the electric. But before we have electricians come out and ask us questions that may be over our heads (like how many 220v and 110v would we need etc.) I figured I would ask for a rough idea on here. You advise will be just that.... advise for me to continue to brain storm on and have the final plan up hopefully by Feb. 1.

I would like to have 3 220v outlets that I would have 3 PDU plugged into for the miners so that if a given.

How many 110v outlets would be needed for fan (3-4 box fans for movement and 3 450 cfm vortex fans for heat exhaust--cool air will be from passive cooling because of the negative pressure.


Questions I wanna know before I ask someone in person:
1. If my panel is only 200amp, can we reduce any amps for the bedrooms to give more Amps for the shed?
2. Can we add a brand new 200amp box just dedicated for the shed but would be billed on the same electric bill monthly? (might be a eclectic company question)
3. Can I put the electrical wiring and the Ethernet wiring in the same trench or run them on the fence line to the shed to save from not digging? (Shed is approx. 170ft away from panel)
