234 TH/s reference from the multi-bin guide. The 220 and 245 TH/s variants have different power ratings.
The reference uses 3,510.0 W. The table and mathematical differences above use your selected tariff, so all displayed comparison costs update together.
188 TH/s upper bin of the listed 184–188 TH/s range. Power is derived from hashrate × efficiency.
The reference uses 3,478.0 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.
