Antminer S19 Family
Bitmain's broadest operator recognition in Korea. XP and k Pro variants dominate new orders; j Pro still circulates second-hand.
Watch industrial tariff steps when stacking XP units on one feed.
Familiar Miner Families
A desk reference before you book a comparison visit. Nominal specs only — your tariff and cooling change the outcome.
We track these families because operators already ask about them by name in quote emails. This page does not rank winners — site conditions pick the fit.
Use it to shortlist two or three names before a Miner Family Assessment. Bring quotes and panel photos to the contact form so we scope the right comparison.
Whatsminer M50 / M50S
MicroBT units favored for hash-per-watt in co-location. Noise in sheds often exceeds factory sheets on tin roofs.
Humidity baffles recommended for uninsulated Gangwon sheds.
AvalonMiner A13 / A14 Series
Canaan batches appear in mixed-family rooms for phase-load spreading. Steadier fan PWM when filters stay clean.
Confirm firmware branch support before mixing with other VLAN policies.
Antminer S21 Family
Newer Bitmain generation entering Korean quotes. Breaker and intake planning from S19 expansions may not transfer directly.
Early procurement quotes should include on-arrival bench verification.
Whatsminer M60 Series
Higher hash per box with corresponding watt density. Co-location noise contracts need pre-check.
Exhaust capacity math before order — not after delivery.
Innosilicon T3+ / T4 Class
Older Innosilicon units still run in low-cost power pockets. Parts scarcity affects repair timelines.
Benchmark before assuming nominal hash on secondary purchases.
