Proto Rig is a shipping modular system
Proto Rig is a direct-sales, field-deployed SHA-256 mining system—not a chip, board-only prototype or generic retail appliance. It combines a chassis, control board, replaceable hashboards, three power supplies and replaceable fan modules.
Maximum configuration contract
- Up to 91 TH/s per hashboard
- Up to nine hashboards and 819 TH/s per complete chassis
- Up to 12,000 W from wall through three 4,000 W PSUs
- As low as 14.1 J/TH in a best-efficiency operating condition
- Up to 9.4 kW per foot at the stated dense configuration
These are separately qualified maxima and a separate best-efficiency claim. The former 14.652 J/TH value merely divided 12,000 W by 819 TH/s and incorrectly implied a guaranteed paired operating mode. Generic scalar comparison and profitability are withheld until one exact paired operating table is published.
Electrical and cooling boundary
Input is 208–240 VAC, 50/60 Hz. The system includes three six-foot C20-to-dual-C19 cables; fanless PSUs use system airflow and support three-phase power balancing. Current, phase mandate, branch protection, receptacle, conductor and installation design are not specified by these facts and require qualified facility engineering.
Air cooling uses 1,300 CFM and six 48 V variable-speed Delta fans up to 9,000 RPM. The system is also described as immersion-ready, but no fluid, flow, pressure, temperature or heat-rejection contract is published; no liquid-installation guidance is inferred.
Physical, environment and software
- 390 × 290 × 500 mm
- 110 lb complete with nine boards; 5.38 lb per board
- 10–90% RH noncondensing; altitude no more than 2,000 m
- Official Proto Fleet/ProtoOS management topology
No exact operating-temperature or acoustic test is published; the former 80 dB value is removed. Official sales are through the manufacturer site/direct channel. MSRP, BTU, home suitability and current economics are unavailable.
