Hello

I used up all the power limitations of my building for my mine and have 21 extra Avalon 741 for sale.  These miners have never been used and are still in the original packaging.

AVALON 741 Bitcoin BTC Bitcoin Cash BCH Miner
Hashes 7.3 TH/S at ~1150W from the wall
You are buying one Avalon 741s miner. The unit was used to mine bitcoin.
 AvalonMiner 741 provides 7.3 TH/s Reliable Hashrate Per Second (RTHS).

Comes in original box with all cables and manuals from Canaan.

The unit doesn't come with PSU.  I can sell PSU separately, contact me if you need one.

Doesn't come with Avalon Miner Controller. Can be sold separately, please contact me if you need one. 

The Avalon 741s are known for being quieter and more dependable than the Bitmain S9.

By connecting AvalonMiner Controller (sold separately) to a single AUC3 (AvalonMiner USB Convertor 3), you may connect five AvalonMiners. For maximum usage, you may connect the AvalonMiner Controller to 4 AUC3 devices which may each connect to 5 AvalonMiners for a total simultaneous management of twenty AvalonMiner 741 to reach 146 TH/s (RTHS).
