About Desktop Ashcore Mining Review
Our history, team, and approach to independent mining hardware assessment in South Korea.
Registered Business
Desktop Ashcore Mining Review Co., Ltd.
Established 2019 in Busan, South Korea.
We began as a two-person workshop in Jung-gu, testing used ASIC units purchased from operators shutting down after the 2018 market downturn. What started as resale quality checks evolved into formal PSU compatibility documentation when we noticed that most hardware failures in Korean climates traced back to power delivery — not chip degradation.
Our History
2019 — Founded by former industrial electrical technician Sang-woo Kim and mining operator Yuna Jeong. First clients were apartment miners in Busan seeking quiet, efficient single-rig setups.
2020 — Expanded lab capacity to bench-test eight units simultaneously. Published our first public PSU rail sag dataset for common Antminer models.
2021 — Added on-site audit service after a Gyeonggi farm lost twelve units to undervoltage during a summer grid event. Began documenting Korean residential voltage patterns by season.
2022 — Formalized the PSU-Matched Miner Selection consultation as our flagship offering. Reached 200 completed consultations.
2023 — Partnered with two Busan electrical contractors for referral on remediation work we identify but do not perform ourselves.
2024–2025 — Extended longevity testing to newer sub-0.1 TH/s efficient units as the market shifted toward lower-power algorithms.
Team
Sang-woo Kim — Lead electrical assessor. Fifteen years in industrial panel wiring before transitioning to mining hardware. Holds Korean electrician certification (전기기능사).
Yuna Jeong — Hardware bench lead. Operated a 40-unit farm in Ulsan from 2017 to 2020. Manages our 14-day longevity testing protocol.
Dae-hyun Lee — Field technician for on-site audits across Gyeongsang province. Background in HVAC, which informs our thermal clearance recommendations.
Working Approach
We accept no affiliate commissions from hardware vendors. Our recommendations come solely from measured data in our lab and field observations. When we suggest a PSU model, it is because we have logged its performance under Korean voltage conditions — not because a manufacturer sent us a sample.
We photograph everything. Every consultation report includes images of your actual panel, cables, and mounting arrangement so that future upgrades reference real conditions rather than assumptions.
Relationship to Clients
Most of our clients are repeat operators. They return when expanding hash rate, changing algorithms, or troubleshooting shutdowns. We do not sell hardware, manage farms remotely, or operate mining pools. Our role ends at the report — though we remain available for follow-up questions within the included window.
Values
Measurement over marketing specs. Factory wattage ratings assume 240V at 25°C. We test at Korean residential voltage with summer ambient temperatures.
Honest scope limits. We tell you when your electrical capacity cannot safely support your hash rate target, rather than suggesting risky workarounds.
Documentation as deliverable. Every engagement produces a written artifact you can hand to an electrician, a business partner, or a future buyer of your equipment.
