Power & Breaker Load
We calculate sustained draw for units rated from 0.05 TH/s through current-generation ASICs, including startup inrush and whether your panel can handle a parallel second miner.

Your Second Miner Deserves More Than a Guess
Panel Hemlockpath reviews ASIC hardware at 0.05 TH/s and above, matching units to your power feed, ventilation, and noise limits before you commit to a second rig.
What We Assess
Every recommendation starts with your existing setup — breaker capacity, intake airflow, ambient temperature, and how close your first unit runs to its rated hash rate.
Thermal & Airflow
Two miners in the same room change heat rejection patterns. We map hot spots, exhaust paths, and whether passive cooling still works at your target hash rate.
Hardware Matching
We compare current and prior-generation miners — efficiency in joules per terahash, firmware support, and parts availability through Korean distributors.
From Operators Who Added Unit Two
These accounts come from clients who engaged us before purchasing their second ASIC. Names are abbreviated per their request.
We assumed any 100+ TH/s unit would slot beside our first S19. Panel Hemlockpath measured our 30A circuit and showed the inrush would trip the breaker every morning restart. They pointed us to a lower-draw unit that still cleared 110 TH/s.— J.H., Bucheon garage operation
The thermal report was thorough — maybe more detail than I needed on duct sizing. Still, knowing exactly where the second exhaust should go saved us from buying another inline fan we did not require.— S.M., Ilsan basement farm
