Every bench report from our Cheongju lab leads with hash rate at the pool and watts at the wall. Operators who understand the relationship between those figures make better scaling decisions.
Hash Rate
We report a 24-hour average after burn-in, not a five-minute peak. Manufacturer spec sheets often cite ideal conditions. Our number reflects Korean line voltage (220V nominal) and 24°C lab intake unless noted otherwise.
Variance within three percent of spec is normal. Five to eight percent may indicate firmware profile, worn fans, or marginal power supply. Beyond eight percent, we flag the unit for inspection before you deploy it.
Wall Draw
Watts at the wall include PSU inefficiency and fan load. A machine rated 800W internal may pull 920W from the outlet. We measure with a calibrated meter on the same circuit used during your installation.
Efficiency matters for breaker sizing. Two units drawing 950W each cannot share a 20A circuit comfortably — the math leaves no headroom for startup surge.
Joules Per Terahash
We calculate J/TH when both figures are stable. Rising J/TH over a second burn-in week often precedes fan failure. Track it if you buy used hardware.
Using the Report With Your Electrician
Hand the PDF to whoever sizes your panel. The wall draw column is what they need — not the marketing hash figure from the seller’s listing.
