141 TH/s, model 240-Ca from the official support sheet. Do not mix these values with a 140 TH/s batch.
The reference uses 3,031.5 W. The table and mathematical differences above use your selected tariff, so all displayed comparison costs update together.
200 TH/s reference. Lower hashrate bins also exist; select the figures on your unit label.
The reference uses 3,500.0 W. The table and mathematical differences above use your selected tariff, so all displayed comparison costs update together.
Lower J/TH means less electrical energy per unit of hashing work. It does not account for purchase price, installation, noise, cooling infrastructure or resale value. Enter comparable hardware quotes and inspect the exact bin before using an estimate in a budget.
