Best places to buy a new antminer s7

Anyone know a reliable site where I can grab one for around $400-$500? My electricity is free here, so I'm looking to set up a little mining operation. What do you think?

I've got a hosting customer with some solid used units he'd let go at quite a bit less than $400. I can provide PSUs as well.

The s7 has been out of production for over a year. There are NO 'new' ones. I would look into Sidehack's offer of proven used ones.

You might find some new ones on sites like eBay but otherwise unless some people have hoarded the miners new and are only now selling them you won't get any new. Also, Bitmain usually mines with the units before they are sold so most units are not truly new even buying directly. The miner is not available on the site new anymore.

I'd be surprised if anyone actually bought miners without the intent of using them. They depreciate in value very significantly. The case I can think of are those who buy more than they can use in order to get a volume discount and then sell the remaining units. Also, it is very common for products to be "burn in" tested so by that definition, they would be "used". That's actually a good thing since it cuts off a good part of the front of the "bathtub curve". (The back of the curve, like computer hardware in general, is not very relevant since the hardware would be long obsolete by then.) If electricity is free, the key factor to look at is hashing power per dollar. The S7 is pretty good if you have a well ventilated place to put it where the noise is not an issue. Also consider researching altcoins.

In the case of Bitmain I've received dusty products that have been used for possibly days, which definitely sounds like they use them to mine for profit before selling em first. They could've made the S7s months before they were actually sold and mined with some in that time before selling.

The last source for "new" S7s I am aware of was NewEgg - but they've been sold out for months now.  It would appear that BitMain dumped the last of their S7 units there as opposed to needing months to trickle them out via their own website.

They do a minimum 72 hour burn-in on all the miners. It is not a full on data center where this happens, and can be a bit dusty. I have personally seen the location where it is done.

Ive got an almost new s7 4.7th/s that was run from jan 12th till the end of feb.  So its got about 6 weeks total use on it that I was thinking of maybe throwing up on ebay.

Antminer S7 is out of stock since summer 2016 latest Last batch was the number 20 .. if i remeber well .. but there is no problem to buy one old S7, if they work properly .. i think is better to buy one S7 who works fine since 1 yers, instead a new one, without know how does it work ...

Kind of a late reply, but do you know if he still has any?

You looking for stock units? Or would a quiet undervolted 900W/3.7TH unit do the trick?

Honestly I would be interested in either.  After months of GPU mining I am trying to dip my toes into ASIC mining before I dive in and start doing pre-orders from China

S7's have been out of production for almost 2 years  so finding a New one is out of the question. However, as Sidehack mentioned he does now <cough> have some that he can undervolt/clock for around 900w and low noise all while running well over 3.2THs or more. They of course had been used running 24x7x365 since the day I had gotten them and range from batch-1 up to the last one produced early 2016 which was finally retired a couple months ago (replaced by 2x Avalon 741's)

I'm setting them for 550MHz (3.7TH max) and around 880-900W stable, but I've got some boards that aren't behaving at low threshold voltage so I can take them back to approximately stock power and hashrate. I say "approximately" because I'd probably tune them individually for more optimal voltage at stock hashrate, which should save some watts. Or, if you were interested in buying one, I could tune it to the optimal hashrate for whatever maximum power draw you wanted to deal with. PM me if you're interested and we can probably work something out.

off topic, how much hashrate i can get for my 2000$? i want to know and where can i buy it?

Be careful with "free" electricity; nothing is "free". If you have a landlord, and he realizes that you spent thousands of dollars in electricity alone, expect an eviction or even your power cut off.

Depends on how fast you want it. There are threads out there that cover the 3 companies pumping out new equipment. Canaan (Minerwarez), Bitmain, Ebang. They all have products working and that ship out, they all have different reliability track records, and different efficiency ratings. So check out those sites, then check the forum threads and boom, you can buy some equipment. Or you can cloudmine, but I think running your own equipment is better; but that's just my opinion. And yes off topic, so don't reply to me, just dig around in the forum.

that is unless; a. have reasonably low cost power at home b. want to mine at home or office where the howling noise of an s9 is unacceptable ASICPuppy has a few available that have been mod'd by Sidehack for lower power and noise.

Does he still have any?  (PM sent to you)
