Mining Calculator Bitmain Antminer T19 Hydro (145Th)

The younger sibling in the T19 Hydro family, the 145-terahash version, represents one of Bitmain’s early experiments in creating a “people’s” hydrominer. On paper, 145 TH/s is still an impressive computing power, capable of generating revenue. This device was conceived as a more accessible entry point into the world of quiet and stable liquid mining for industrial sites that had already invested in the appropriate cooling infrastructure.

But the devil, as always, is in the details, and in this case, in the power outlet. A consumption of almost 5.5 kW at a hash rate of 145 TH/s translates into a catastrophic energy efficiency rating by 2024 standards – about 37.5 J/Th. This makes it one of the most power-hungry devices in its class. Any savings on the initial cost of this miner will be rapidly swallowed by electricity bills. In current realities, when flagships are fighting for every joule below 20 J/Th, the T19 Hydro looks like an energy vampire from the past.

The only thing that salvages its reputation is its “hydro” nature. A noise level of 40 dB allows one to forget about soundproofing issues and opens the door for ultra-dense equipment installation. Stable operation without temperature fluctuations, characteristic of air cooling, is also a significant advantage, potentially extending the life of the chips. However, make no mistake: this is not a standalone device, but only an element of a complex system requiring external cooling towers and pumps.

The verdict is simple: the Antminer T19 Hydro at 145 TH/s is a relic of a bygone era. Its place today is exclusively at facilities with conditionally free electricity or where its enormous heat dissipation can be effectively utilized for heating. For any commercial miner who pays market prices for electricity, this device is a direct path to operating at a loss. It clearly demonstrates the gigantic leap in energy efficiency the industry has made in just a couple of years.
