Product Details

Proto Rig 819 TH/s Air Cooled SHA 256 Bitcoin Mining System

The Proto Rig produces 819 TH/s at 12,000W from nine individual hashboards, each contributing roughly 91 TH/s. It is the highest output air cooled single chassis Bitcoin miner currently available from any manufacturer, and its modular architecture makes it fundamentally different from every other ASIC on the market.

Traditional ASICs are sealed units. When a hashboard fails or a newer chip generation launches, the entire machine gets replaced. The Proto Rig's nine hashboards are individually removable and replaceable on the rack without tools in under 90 seconds. If one board fails, you lose 91 TH/s (roughly 11 percent of output) instead of the entire machine. When Proto releases next generation hashboards, you swap boards into the existing chassis rather than buying a completely new miner.

This modular upgrade path is the Proto Rig's primary differentiator. Over a multi year deployment horizon, the ability to replace boards instead of entire machines reduces capital expenditure on hardware refreshes significantly.

Proto Fleet is the company's open source fleet management software with open APIs for integration with existing monitoring infrastructure. Unlike proprietary management tools from Bitmain or MicroBT, Proto Fleet is designed for customization and third party integration.

Efficiency at approximately 14.65 J/TH. Six high performance fans at 80 dB (louder than standard 75 dB ASIC miners). 208 to 240V single phase. Three PSUs rated at 4,000W each. Fanless PSU design cooled by the system fans. 390 x 290 x 500mm at 50 kg. Ethernet. 5 to 45 degrees Celsius at 10 to 90 percent humidity. Bitcoin, Bitcoin Cash, and all SHA 256 coins.

Proto Rig 819 TH/s Air Cooled Bitcoin Miner Near Petahash Output

Proto Rig. 819 TH/s from nine modular hashboards at 12 kW. Highest output air cooled Bitcoin miner available. Each hashboard contributes roughly 91 TH/s and swaps tool free in under 90 seconds.

The modular architecture changes mining economics. Replace individual boards instead of entire machines when failures occur or newer chip generations launch. Extends chassis lifespan across multiple hardware generations, reducing capital cost of fleet refreshes.

Proto Fleet open source management software with open APIs. Integrates with existing monitoring infrastructure. 208 to 240V single phase. Three 4,000W fanless PSUs. 80 dB (louder than standard 75 dB). 50 kg at 390 x 290 x 500mm. Approximately 14.65 J/TH. Ethernet. Bitcoin, Bitcoin Cash, all SHA 256.

5 to 45 degrees Celsius at 10 to 90 percent humidity. Proto is a new entrant debuting with this modular flagship. Evaluate the engineering innovation against the shorter brand history compared to Bitmain and MicroBT.

FAQ

Frequently Asked Questions

The Proto Rig delivers 819 TH/s of SHA-256 mining power, one of the highest air-cooled outputs available in a single system.

Yes. The Proto Rig achieves near-petahash output using air cooling only. No water or immersion infrastructure is needed.

It draws 12,000W at full load, requiring dedicated industrial electrical connections with appropriate circuit capacity.

Bitcoin (BTC), Bitcoin Cash (BCH), and all other SHA-256 algorithm cryptocurrencies.

No. The 12kW power draw and heat output require dedicated mining facilities with industrial electrical and ventilation.

In hashrate terms, one Proto Rig produces the equivalent of roughly four 200 TH/s class miners, consolidated into a single system.

The Proto Rig achieves 14.7 J/TH, in line with current-generation air-cooled SHA-256 hardware.

High-capacity fans are required for 12kW of heat dissipation. Expect industrial noise levels appropriate for dedicated mining environments.
