Las clasificaciones usan la moneda principal del algoritmo (BTC para SHA-256, LTC + DOGE para Scrypt): las cadenas secundarias pequeñas pueden pagar más por hash hoy, pero no pueden absorber mucho hashrate.
El Bitmain Antminer T21 (233Th) es un minero ASIC de Bitmain para el algoritmo SHA-256, con 233 TH/s a 4,427 W. Salió al mercado en febrero de 2024. Su eficiencia de 19.0 J/TH está cerca de la mediana de los mineros SHA-256 que seguimos (20.4 J/TH). A $0.036/kWh ocupa el puesto 108 de 299 mineros SHA-256 por beneficio diario y gana unos $4.65 al día minando BTC. El mejor precio en AsicProfit es $996. Con los datos de hoy se pagaría solo en unos 215 días. Con 75 dB su sitio es una instalación minera o un centro de hosting.

T21 shows warning J1:2 and power voltage read failed. What does it mean?
AsicProfit SupportAsicProfit · 27 oct 2026
It points to the power side: the control board could not read the supply voltage, and the miner restarts. Measure each phase under load, not just at idle, and check the PDU sockets and cable terminations, since loose pins at the back of the socket are a known cause. If all three phases are healthy, the power supply is the next suspect. A unit under warranty should go back to Bitmain or an authorised repair centre.

Is the T21 three-phase? I only have single-phase 240V at home.
AsicProfit SupportAsicProfit · 24 oct 2026
Yes, the standard T21 ships for 380-415V three-phase input, which surprises many buyers because most Antminers in this class are single-phase. Owners confirm it needed electrical upgrades and three-phase PDUs. A few hobbyists run modified T21s on single-phase power supplies at reduced wattage, but that is a do-it-yourself conversion outside the warranty. Check your supply before you order.

can i just pull the plug on a T21 to switch it off
AsicProfit SupportAsicProfit · 18 oct 2026
Not on the T21. An owner reported that its three-phase connector is not designed to be pulled under load, and if neutral breaks before the live pins it can damage the cable and power supply. Switch it off at the breaker first, then unplug. Frequent hard power cycling is also hard on solder joints, so fix the cause of any overheating rather than repeatedly cutting power.

Why is the T21 cheaper than the S21, and is it the better buy?
AsicProfit SupportAsicProfit · 15 oct 2026
The T21 does 190 TH/s at 19 J/TH, while the air-cooled S21 does 200 TH/s at 17.5 J/TH. You pay less up front but more electricity per terahash, so the T21's margin shrinks faster when difficulty rises or the Bitcoin price falls. It also needs three-phase power. With cheap three-phase electricity it can make sense; otherwise compare both in the calculator on this page at your power price.

My T21 keeps overheating in summer and some boards now show 0 of 108 chips. Hardware or cooling?
AsicProfit SupportAsicProfit · 1 oct 2026
It can be both. Owners report T21s struggling in hot containers, with corner chips running much hotter than the rest, and boards that lose chips after a restart. Check fans and intake temperature, reseat the hashboard and control board cables, and test boards one at a time. Repasting the heatsinks has helped several owners. Faulty PDU socket pins that drop a phase can also cause odd chip errors. Underclocking through the hottest months is a common workaround.

How loud is the T21 and how much heat does it put out?
AsicProfit SupportAsicProfit · 28 sept 2026
It is listed at about 75 dB, which is not suitable for a living space. Nearly all of its roughly 3,610 W becomes heat, about 12,300 BTU per hour, so the room needs strong ventilation or ducting for the exhaust. The listed operating range is 5 to 45°C, but owners advise keeping intake air well below the top of that range for long life.
