Topic: WTS: Antminer S1 Bitcoin Miner + PSU's (x2) 0.75BTC + shipping (Read 1870 times)

.2 each plus shipping.

I offer .2BTC each..no psu's

Bump

FIRESALE:

Price is now 0.75BTC + shipping costs for both miners and the power supplies.

Ah, I am talking all 400GH/s.

Even with free electricity it's only .0067 at current difficulty and the electricity is not included yet. 

I guess I'll just hold onto them then or what till someone with free electricity wants them.
I still think your numbers are off though. It doesn't take 10 days to make .04 it takes < 3

I pay .16 for electricity.  Alot of people in Europe pay .35 or more.

Maybe you dont see the difficulty moving up to 17 Billion next week, and increasing every 13 days after that.

Nah, that's a crock. Not sure how much you pay for electricity but that seems outlandish

More like .15 btc remaining in lifetime for each mining at 17% diff rise and .16 electricity.

Are you serious about this? If you let them run forever with free electricity thei will never achive positive ROI at this price.

Sorry sir going to have to refuse that offer. I have free electricity and they are running 200GH/s each.
When you factor in shipping I can't really afford to let them go at anything less than the ask price.

Pretty costly for ROI, good luck on selling them at that price , but if willing to sell for .25 like others offer pm me

Ohio..I have plenty of PSU's laying around so not wanting those.

Hmm. Never thought about selling just the miners. Would rather sell as a whole package. :/
I'll get back to you sir. Where in the US? If you don't want to say in public  just pm me.

What about the 2 x antminers and no PSU's shipped USA?

Specs:

Hash rate: 180 GH/s (~200 GH/s Overclocked)
Power Consumption: 360 watts (~450 if overclocked)
Efficiency: 2 watts per GH/s
Power Input: +12 Volt DC
Dimensions: 13.5cm x 15.5cm x 30cm
Network: Ethernet and WiFi
Cooling: 120mm fan w/ twin heat sink

 


Both units are about a month old and have had been running great in this time period.
They have been overclocked to maximize profitability and run ~200GH/s with 5% variance.

The miners have a 3 month warranty but need to be reset to stock factory settings before sent in as Bitmain will not service units that come in overclocked.

Slightly more power is used when the units are overclocked (~450 watts).
A factory reset could be performed on both if you wish to return them to stock.
These miners are still quite profitable at the moment (depending on electricity costs) and likely will be for a decent time frame.
They also support undervolting via an easily do-able mod, which will extend the usable lifetime of the hardware, allowing them to be run at a profit for the next 8 months or more. (Even longer if BTC prices raise as they have recently or if you have low/free cost of electricity)


Powering these units are 2 Corsair TX750 power supplies which were also bought new at the same time as the S1 Antminers. These are high end 80-plus bronze rated power supplies and come with a 5 year warranty. They run quietly under load and provide adequate voltage as well as amperage for the miners. In theory you *could* reset the miners back to 180 GH/s and run them off of 1 PSU but it would be operating past its limit and likely burn out given the high constant load. Another S1 Antminer could be powered by the current pair of TX750's if you wish to expand your mining operation.

A climate controlled space is preferred for the hosting and running of these miners as they do produce a fair amount of heat while running. They run at a decent quiet volume when ambient temperature is <23 Celsius. Automated fan controls within the S1 Antminer sense temperature and will speed up or slow down the fan as needed to keep the device from over heating. Personally I run the air conditioner during the day and open a window at night and they seem to have no problem temperature wise.

 

included:

2x S1 Antminer (overclocked ~200GH/s)

2x Corsair TX750 Power Supply

2x Detachable Wifi Antenna

1x 1' RJ45 ethernet cable (for configuring miners)

All necessary cords are included as well as the original boxes.




The reason I am selling these units is because I have massive debt after the whole IPO fiasco and need to pay back investors.
Wish I could hold onto these units, as they will produce far more Bitcoin in their lifetime then what I am asking for them.

Buying them as a pair would be highly preferred but a single S1 Antminer + PSU can be purchased for a slightly higher price.

The Setup:



Buyer backed out it seems. :/

These are on sale priced to move immediately @ 0.75BTC for everything listed / pictured above. (Power bar / shelf not included)
Shipping costs will be added onto the total and you will have the option between regular or express post.
Miners are boxed up and ready to ship immediately after payment is received.

Cheers,
