Buying guide
New vs used
Both are real options. The difference is warranty coverage and how much of the machine's life is already behind it.
New
- Sealed from the manufacturer, zero run hours.
- Remaining manufacturer warranty (varies by unit).
- Rated hashrate and efficiency out of the box.
- Higher price per terahash; longer remaining service life.
- Best when you are hosting long-term or financing the unit.
Used
- Pulled from operating fleets, cleaned and re-pasted where needed.
- Every unit is bench-run before it ships and the result is logged.
- 7-day DOA policy from delivery — if it doesn't hash, we make it right.
- Typically 20–35% below new for the same model.
- Best when you want hashrate per dollar today and can accept variance.

How we test
- 01 — Intake: serials recorded, chassis and PSU inspected for heat and water damage.
- 02 — Bench run: unit is powered under load and hashrate, chip count and board temps are captured.
- 03 — Service: fans replaced, thermal paste redone and dust cleared as needed.
- 04 — Pack out: foam-boxed for single units, strapped and crated for multi-unit orders.
How we grade used units
A
Like new
All boards hashing at spec, light cosmetic wear, original fans.
B
Clean
All boards at spec, visible scuffs or replaced fans.
C
Working
Hashes within 5% of spec, heavy cosmetic wear. Priced to move.
