Watts Tell the Truth About Your Rigs
We bench-test cryptocurrency mining hardware at 0.05 TH/s and above, measuring joules per terahash under controlled load so you know what each unit actually costs to run.
What We Measure
Hashrate alone does not pay the electricity bill. Our reports focus on the ratio that matters.
Wall-Draw Wattage
We record true AC consumption at the outlet during sustained hashing, not manufacturer spec sheets or DC-side estimates.
Thermal Stability
Ambient temperature, inlet airflow, and chip junction readings are logged across a 4-hour run to catch throttling behavior.
J/TH Efficiency Score
Every unit receives a joules-per-terahash figure you can compare directly against your tariff and farm layout.
Benchmark Services
From a single pre-purchase screen to full farm audits.
Comparative Rig Analysis
Side-by-side J/TH benchmarking of two to four mining units under identical lab conditions.
On-Site Power Assessment
We visit your farm or hosting bay to measure aggregate draw and spot-check individual rack units.
Performance Benchmark Report
Full joules-per-terahash analysis for a single mining unit under controlled 4-hour load conditions.
From the Field
Operators who used our numbers before committing capital.
We brought three used S19 units to Daegu before signing a warehouse lease. Two matched their advertised efficiency; the third was drawing 400 watts over spec. That one report saved us roughly six months of margin on a 48-rig deployment.— Hyeon-jun Park, small-scale farm operator, Gyeonggi
The write-up was thorough and the lab conditions were documented clearly. I would have liked a faster turnaround during peak season, but the numbers themselves were solid enough to renegotiate our hosting contract.— Mei Lin, hosting facility manager, Busan
