Bitmain Antminer T9+ New In Box 10.5 TH/s

Description

New Bitmain Antminer T9+ 10.5 TH/s Bitcoin Miner
Bitmain produced the Antminer T9+ as an industrial version of the Antminer S9. It is a little bit slower, but more resilient and stable.
The miner is new - never used and still sealed in its original box. It is a surplus from our Oregon data center.
Being unopened, the miner has the older version of the Bitmain firmware. We greatly recommend you upgrade it to the Bitmain-Xilinx-2019-07 T9+ version. This version will significantly improve the efficiency and also enable you to easily adjust speed/power consumption from the miner control panel. If you upgrade the firmware beyond the 2019-07 version, you'll not gain in performance but Bitmain will "lock" your miner SSH access.
A power supply is not included in this listing.
As with all large bitcoin miners, the T9+ should be ran on a 220V circuit. However, with the upgraded firmware, it's possible to reduce the power consumption to 1000W or under, making it acceptable to run the miner on ordinary 110V outlets.
With the
Bitmain-Xilinx-2019-07 firmware, the average at-the-wall power consumption is as follows:
Stock mode: 10.5 TH/s  @1250 Watts
Low-power -0.0TH mode: 10.5 TH/s @1090 Watts
Low-power -0.5TH mode: 10.0 TH/s @1000 Watts (recommended setting)
Low-power -1.0TH mode: 9.6TH/s @ 960 Watts (suitable for 110V)
Low-power -2.0TH mode: 8.7TH/s @ 860 Watts (suitable for 110V)
... and so forth. The T9 is a good platform for experimenting with ASIC settings.
With the out-of-the box firmware, the power consumption is about 1400W @ 10.5 TH/s. We can upgrade the firmware for you before shipping if you send us a note requesting it.
Important ! Please Note Before Buying:
Non-Returnable Item:
Miners are not returnable unless they are defective out of the box. The reason is that miners are a speculative asset, subject to the
volatile
nature of cryptocurrencies. Please inform yourself about the economic risks of mining and the possibility of loss. You cannot return a miner just because the market has become unfavorable.
Non-Returnable Item:
Another reason why miners cannot be returned is that they can be
damaged
through inexperienced use.
Miners cannot be returned if they have been overheated, overclocked, or otherwise damaged/misused during operation.
Noise:
The Antminer T9+ is loud. This is not a "living room" appliance! The noise emitted by the miner depends on temperature and on where it's installed. Keep the miner cool to minimize the noise and make sure you have a location where it will not disturb you.
Heat:
The Antminer T9+ generates more than 1kW of heat. This is about as much as a small electric
heater
on the low setting. You cannot put it into a cabinet and close the door. Basements or garages are the preferred location for miners.
Don't install third party "firmware":
Please do not install third party (non-Bitmain) firmware. Most such "firmware" is basically
malware
that will syphon mining revenue from you and often damage your machine. Amity Labs miners ship with original Bitmain software and nothing else.  Return of malfunctioning miners will be denied if you have tried to install third party firmware or any other third party (non-Bitmain) application!
Dont go overboard:
Please do not purchase more than
one
machine unless you're an experienced miner. Mutiple miners however require properly set-up ventillation and 220V proper power distribution. Contact us for help if planning a multi-miner operation.
Why mining then?
Mining crypto may be cheaper than buying it. The machine provides a physical hedge against volatility and may have residual value. Miners are the people who keep the blockchain secure thanks to the cryptographic computing power of their machines, and thus they are part of a distributed financial network that may become the future backbone of finance. Finally, a small miner makes for a nice free heat source in cold weather. Please remember that the economics of mining depend on several factors - evaluate carefully your situation before getting into mining.
Amity Labs is one of the oldest miners / mine builders in the US. Based in Oregon, we have helped thousands of people get started with mining and become part of the cryptocurrency revolution.
