Mining rigs above 0.05 PH/s, judged for the wrench—not the brochure
We document which ASIC and GPU farm units in South Korea can be opened, serviced, and kept running when hash boards fail—not which models look impressive in a rack photo.
Why repair access matters at this hash rate
At 0.05 PH/s and higher, a single failed hash board or blown VRM can idle an entire row. Buyers who cannot source pads, screws, or replacement boards locally pay weeks of downtime and freight from overseas depots.
Our reviews score each unit on documented service manuals, spare-part lead times through Korean distributors, and whether local technicians have successfully replaced fans, hash boards, and power supplies without voiding coverage.
Equipment we assess
On-Site Rig Assessment
A technician visits your farm or container to score repair access, spare-part paths, and hash-board swap feasibility on rigs at 0.05 PH/s and above.
From ₩450,000 per site visit (up to 20 units)

Parts Sourcing Review
We trace fan modules, hash boards, PSU gaskets, and control boards for your fleet and document realistic lead times through Korean channels.
₩280,000 per fleet review (up to 15 SKUs)
View detailsWhat operators tell us
They walked our Ulsan container through fan routing and showed which Antminer S19 boards we could swap without sending the whole unit to Seoul. Downtime dropped from twelve days to four.
— Hyeon Park, 0.08 PH/s container farm
The parts list for our Whatsminer M30S was honest—two items still ship from China, but PSU gaskets arrive in Busan within a week. I wish the cable routing diagram had been clearer on first visit.
