SHA256 ASIC Miner for Bitcoin

The Antminer S21 Pro+ 234T is an air-cooled ASIC mining machine built for the SHA256 algorithm. It delivers a hashrate of 234 Th/s while drawing 3510 W at the wall, yielding a power efficiency of 15 J/TH. The unit operates on 220–277 V AC input at 50–60 Hz with a maximum current draw of 20 A and requires a 4000 W power supply. It connects to the network via RJ45 Ethernet 10/100M.

Build Integration and Requirements

The miner measures 450×219×293 mm and weighs 18.5 kg, fitting standard rack or shelf deployments. It produces 76 dBA at 30 °C, so acoustic planning is necessary for indoor sites. Operating temperatures range from –20 °C to 45 °C with 10–90 % relative humidity, and it is rated for altitudes up to 2000 m. A 4000 W PSU and a 220–277 V circuit capable of 20 A must be provisioned before installation.

Upgrade Context and Value

Replacing older SHA256 ASICs that run above 30 J/TH cuts electricity cost per terahash by roughly half at current rates. The efficiency gain pays back the hardware investment faster when power prices exceed typical industrial tariffs. If your existing fleet operates near 45 J/TH or higher, the jump to 15 J/TH delivers a clear margin improvement within a single difficulty epoch.

Domande su questo articolo

What is the maximum operating temperature before the S21 Pro+ 234T throttles under sustained load?

The miner is rated for continuous operation up to 45 °C; above this temperature the hardware will begin to throttle to protect itself.

How much noise and heat does the S21 Pro+ 234T produce when running all day?

It emits 76 dBA at 30 °C ambient and draws 3510 W, so virtually all of that power becomes heat that must be exhausted from the room.

What power infrastructure must already be in place for the S21 Pro+ 234T to operate?

A 220–277 V AC circuit capable of delivering at least 20 A (4000 W) with a suitable IEC C19 or hard-wired connection is required before the unit can be powered on.
