The Antminer S19J Pro+ appeared in December 2022 as an interim model in the S19 series, between the S19J Pro and the S19K Pro that followed later. The Bitcoin miner is built for the SHA-256 algorithm and can be used to mine Bitcoin or Bitcoin Cash. We carry it at 117 and at 120 TH/s, and both levels work at 27.5 joules per terahash. Four fans cool it, it puts 13.7 kilograms on the scale, and it is fed single-phase with 200 to 240 volts.
Performance levels of the Antminer S19J Pro+
- S19J Pro+ 117 TH/s at 3,218 watts (BTM-S19JPROP-117TH)
- S19J Pro+ 120 TH/s at 3,300 watts (BTM-S19JPROP-120TH)
Build j1-12 comes in four levels from 109 to 120 TH/s, all at 27.5 joules per terahash at 25 degrees. On hashrate Bitmain states a tolerance of three percent upwards, on power and efficiency five percent either way. Our two levels are the upper two of those four.
Design, power connection and cooling of the S19J Pro+
At 400 × 195 × 290 mm the housing has the same outer dimensions as the S19J Pro, with the power supply built in. The carton measures 570 × 316 × 430 mm and weighs 15.74 kilograms. Noise is 75 dB. Operation is cleared by Bitmain from 0 to 40 degrees, storage from minus 20 to 70, in both cases at 10 to 90 percent humidity with no condensation, and altitude up to 2,000 metres. A single unit gets by without an exhaust system; it only needs a place where fresh, cool air keeps flowing in.
Power comes from two mains cables with IEC connectors, 10 amps each, no more than 20 amps together, at 200 to 240 volts and 47 to 63 hertz, plus the RJ45 socket for the network at 10/100 Mbit.
The S19J Pro+ appears twice in the Braiins OS model list, once as the regular version and once as a variant without PIC, and Vnish offers its own firmware for it. Both firmwares regulate each hashboard individually, throttled for lower consumption or overclocked for more hashrate at slightly worse efficiency. If you want the firmware on the unit when it ships, we do that for 29.90 euros net per unit; this applies to miners you run yourself, units in our hosting are excluded. A flashed unit no longer has a warranty, and Bitmain and we handle that the same way.
As standard, Bitmain gives a 365-day factory warranty on the machine, counted from the shipping date; our standard price always includes our own warranty.
Comparison with the previous and next generation of the S19J Pro+
The S19J Pro+ replaced the Antminer S19J Pro and was in turn replaced by the Antminer S19K Pro. The step into a new generation then came with the Antminer S21, and the Antminer S23 marks the generation after that. Ordered by efficiency:
- Antminer S19J Pro: 29.5 to 32.2 J/TH (90 to 104 TH/s at 2,900 to 3,068 W)
- Antminer S19J Pro+: 27.5 J/TH (117 to 120 TH/s at 3,218 to 3,300 W)
- Antminer S19K Pro: 23.0 J/TH (105 to 120 TH/s at 2,415 to 2,760 W)
- Antminer S21: 17.5 J/TH (151 to 200 TH/s at 2,643 to 3,500 W)
- Antminer S23: 11.0 J/TH (318 TH/s at 3,498 W)
From the S19J Pro to the S19J Pro+ the drop is two joules per terahash, just under seven percent. The S19K Pro then takes off 4.5 joules per terahash, a sixth, the S21 a further 5.5 joules, just under a quarter, and the S23 another 6.5 joules, a good third. The miner comparison puts the daily yield of the S19J Pro+ side by side with every other unit we offer.
Verdict: Bitcoin mining with the Antminer S19J Pro+
The S19J Pro+ is a good successor model within the S19 series, an interim model that appeared before the S19K Pro. It is a solid miner that was deployed very widely by miners all over the world, and the experience with it is good.
It can still be used today, but only where very cheap energy is available.
Whether that is the case for you is shown by the Bitcoin mining calculator as soon as you enter your electricity price and the level of the S19J Pro+. Two live values flow into that, the Bitcoin network hashrate and the price, both from the cockpit; one step further in the cockpit sits the list of Bitcoin mining pools with share and fee.
