Bitmain Antminer T21 190TH Value Tier Air Cooled SHA-256 Bitcoin Miner

Bitmain's budget T series makes a quiet return. The T21 at 190 TH/s and 3,610W carries the tradition of offering lower hashrate at lower acquisition cost compared to the S series. The S21 produces 195 to 200 TH/s. The T21 sits just below, presumably from chips that narrowly missed S21 qualification. Efficiency around 19.0 J/TH. Competitive with the S19 Pro++ (26.0 J/TH) and respectable for a budget line product. Not in the same class as the S23 (11.0 J/TH) but significantly better than legacy hardware still circulating on the secondary market. Universal 100 to 240V. At 220V draws about 16.4 amps. 75 dB standard industrial. Daily electricity at $0.07 per kWh: $6.06. Monthly: $182. Bitmain… Antminer firmware ecosystem with fleet management tools. Ethernet. Third party firmware options like Braiins OS may be available for T21, though T series historically receives less third party attention than S series. The T designation has always signaled "value tier" in Bitmain's lineup. T9, T17, T19, and now T21. Each generation's T model offered a slightly less powerful alternative to the S model at lower cost. For fleet operators filling rack space on tight budgets, the T21 delivers S21 class hashrate without S21 pricing. 13.5 kg. 5 to 45 degrees Celsius. Standard Antminer chassis. The T21 competes directly with the MicroBT M60S (186 TH/s, 3,441W) and Canaan A1466 (150 TH/s, 3,230W) in the 150 to 200 TH/s air cooled tier.
