Purpose-built Bitcoin miner

The Antminer S21 XP 270T is an air-cooled ASIC designed for SHA-256 mining of Bitcoin, Bitcoin Cash and Bitcoin SV. It delivers a nominal hashrate of 270 Th/s while drawing 3645 W from a 220–277 V AC supply, yielding an efficiency of 13.5 J/TH. The unit weighs 18.7 kg and measures 450 × 219 × 293 mm.

Network and environmental limits

Connectivity is provided by a single RJ45 Ethernet port operating at 10/100 Mbit/s. The miner tolerates ambient temperatures from -20 °C to 45 °C and relative humidity of 10–90 % non-condensing, with a maximum operating altitude of 2000 m. Acoustic output reaches 76 dBA at 30 °C while moving up to 480 CFM of air through four fans.

Installation notes

The machine ships in a 630 × 350 × 430 mm carton weighing 21.5 kg and requires a single-phase 220–277 V circuit rated for at least 20 A at 50–60 Hz. No wireless or secondary network interfaces are present, so a wired Ethernet drop is mandatory. Bitmain voids coverage if firmware settings are altered without prior consent.

Questions sur cet article

What power supply and circuit do I need to run this miner?

It requires a 220–277 V AC single-phase supply rated for at least 20 A and draws 3645 W at the wall.

How much heat and noise will the unit add to my space?

It exhausts up to 480 CFM of air and produces 76 dBA at 30 °C ambient, so plan for strong ventilation and sound isolation.

Which coins can I mine and how do I connect it to the network?

It mines SHA-256 coins such as BTC, BCH and BSV and connects via a single RJ45 Ethernet 10/100 M port.
