USED Canaan Avalon 741 8TH/s ASIC Bitcoin Miners SHA-256

Excellent Condition Canaan Avalon 741 7.3TH/s ASIC Bitcoin Miners SHA-256. Miners are used but in excellent condition. These are 7.3TH/s miners and can be reliably undervolted for power efficiency or overvolted to reliably provide a 8.0-8.4 TH/s hash rate. This can be done in the setup and admin interface. We have had these miners in service in our climate controlled mining room for approx 7 months. I have run just about every piece of BitCoin mining gear in our racks, and these are by far the most reliable, coolest running, most solid miners on the market in my experience. Each miner includes a Avalon AUC3 I2C 5PIN Cable and Avalon Miner USB Converter 3 (AUC3). Controller (Raspberry Pi) and power supply (PSU) are NOT included, so you will have to purchase those separately. Up to 20 of these miners can be daisy chained to run on 1 controller unit. Miners will be fully checked 100% and factory reset prior to shipment. We will package the miners VERY WELL for shipping in their original boxes, and the shipment will be fully insured. These miners will be shipped fully checked and functional, and absolutely NO RETURNS will be accepted for any reason. Please make sure you are familiar with the function of this equipment and know how to correctly hook it up and use it before powering it up. 5% Discount for full direct payment in BTC, exchange rate to be agreed upon at time of payment.
