| Manufacturer | Innosilicon |
| Algorithm | Equihash |
| Hashrate | 50 KSol/s |
| Power Consumption | 620 W |
| Status | Historical OEM reference |
A9 ZMaster exact historical evidence
The manufacturer launch record and exact A9 manual support a nominal 50 KSol/s Equihash solution rate and 620 W at-wall power. The manual states ±8% for hashrate and ±8% for power.
| Evidence field | Published value | Scope |
|---|---|---|
| Solution rate | 50 KSol/s ±8% | OEM A9 manual |
| Wall power | 620 W ±8% | OEM launch/manual |
| Calculated nominal efficiency | 12.4 J/KSol | 620 W ÷ 50 KSol/s; derived, not OEM-published |
The OEM does not publish an efficiency value or efficiency tolerance. Because hashrate and power each have their own tolerance, 12.4 J/KSol is nominal arithmetic only and is not assigned an ±8% band.
Exact-model boundary
A9, A9+ and A9++ are distinct entries in the manufacturer support selector. No suffix-variant specification or firmware is inherited by this record.
Electrical and operating evidence
The exact A9 manual identifies a 1000 W-or-greater external PSU requirement, seven PCIe 6-pin power connections, Ethernet, 360 × 125 × 155 mm dimensions, 5.13 kg without PSU, and a 0–40 °C operating range. Facility-side circuit requirements remain PSU- and site-specific.
Lifecycle and current-use boundary
This is a historical technical reference. Current OEM support, EOS status, network compatibility, coins, revenue, profitability and home-use suitability are not verified. No current availability or economics claim is made.
