S19 90T Antminer BTC Miner 3105W Mining 34.5J/T​​

Product Description

Bitmain Antminer S19 Antminer BTC Miner bitcoin machine mining 90Th/s:

Antminer S19 rated computing power: 90TH/s; energy efficiency ratio: 34.5J/TH±5%; wall power consumption: 3105W±5%.

It adopts an aluminum alloy profile electromechanical integrated design, parallel four-fan structure, bare metal size is 400*195.5*290mm, and the net weight of the whole machine is about 14.2 kg. The shape is square, simple, and regular, and the space is saved to the greatest extent.

The air outlet fan is internally tested with a solid air grid to prevent foreign objects from entering.

After removing the fan, the removable hash board design can be seen after removing the fan. Unscrew the two screws on the top connecting the power supply, unplug the main control board cable, and the hash board can be easily pulled out.

The components at the top of the power box provide a safe distance between the power supply and the case enclosure.

Top: The wiring between the power supply, the hash board, and the main control board is neat. In addition to the power line and data line, there is also a voltage regulation line connecting the main control board and the power supply, which is responsible for regulating the voltage of the power supply during the operation of the mining machine.

The middle of the connection between the main control board chip and the front case is the Ethernet interface, and the SD card slot is next to it.

Close-up of the front and back of the hash board, with two heat sinks on the front, the front is light and the back is heavy, pasted with silicone grease, and then reinforced with spring screws.

77 independent heat sinks, effectively improve the heat dissipation capacity. There are a total of 228 hash boards in the whole machine.

The silicone grease is evenly spread between the chip and the heat sink. The chips are arranged in such a way that the density at the air inlet is high, and the heat sink is thin. The further to the air outlet, the smaller the chip density and the thicker the heat sink. This ensures that the whole machine dissipates evenly.

Each machine will be tested for computing power before it is sent out, and after the test is completed, it will be individually packaged and sent out.
We will send out the machine within 7~14 working days after you make the payment.

We have our own mine, have our own operation and maintenance personnel, and cooperate with multiple maintenance centers. Before the mining machine is shipped to you, we will test the mining machine and send the test video to you to ensure that the mining machine in your hand can operate normally and minimize the loss of transportation
