Thank you again for the great info and replies!

I'm starting to feel like the Canaan 741 might be a good first purchase, of course if I can get one.  It's not a super powerful unit, but the cost is really reasonable ...for now...again, if I can acquire one.

My father has a rental house sitting empty that has a very large power panel on it.  It has room to make up to 8 240V breakers on it!!!   I need to contract an electrician and get an estimate for a PDU or some form of one...I hope the guy knows alot about electricity!  (In my town, you never know how much they really know! hahaha)

The house has a whole house exhaust fan in the ceiling not far from the area I would setup my units and the noise won't matter as it's empty! 

It's hard not to want to go crazy and jump in....doing all the calculators makes this look like a sure money maker and I get all excited about it and want to rush, but my wife is very skeptical and to her EVERYONE and EVERYTHING is a scammer....She's been burned on Ebay as she is a very active seller of unrelated things...

I want to do it right though too.

Thank you for the great info!!!

Thank you both again so much for the helpful replies!

At this point getting my hands on hardware is the only consideration as to what my power consumption needs will be.


Might I inquire your preferred places of purchase for quality mining hardware? 
I've looked at bitmain, Blokforge, and a couple others that look questionable....it's a maze out there!

I appreciate any info you may have.

I also noticed bitmain only takes bitcoin as payment, which is ok, I'll just need to buy some bitcoin and get my feet wet! lol

Thank you both for great info!

My wife and I are really interested in getting started, so having an electrician put in a dedicated 220V line for a 4 pack of higher end miners is what we originally talked about...

You given me something to think about regarding the noise....i never realized they'd be Vacuum cleaner loud....   I'm used to having loud Server fans running in my office but
this sounds WAY louder!!!   lol...i don't think I'd like it in my current setup space at all hahahaha....3 feet from my main computer.

If I had a 220v line ran, how do you split it off for more than one miner?   In the US here where I am, a 220V line is typically for a single appliance and no more.

I love the plug image you gave me by the way.

Would an electrician know how to set that up for more than one miner? 

I realize getting my hands on a miner at all right now is practically wishful thinking, but my wife is on board so we're really going to try and get started.

I am thankful for any more info and advice!!!

Thank you both

Hello world.

So I totally have been watching this for some time and decided to try and learn more about mining hardware.

I'm trying to understand their power supply requirements better as some units say they are rated for 220V (example the DragonMint)

I do want to try my hand at some gear soon, (assuming I can get my hands on some) but

The miners aren't all 220V power are they?    What kind of power infrastructure do I need to plan for here?

What's odd is that DragonMint says it's 220V but uses a "standard" power cable like our computers all use...hence my confusion on the matter.

On one page I saw the Antminer S9 PSU with 10 plugs has spec info for BOTH power levels, 110v and 220v...are the PSU's rated for EITHER or one or the other?

I've yet to touch my first unit, but I'd sure like to prep a proper electrical plug for it if I ever do get one...

Any advice on this topic would be greatly appreciated.
