Proto RIG – 819 TH/s

Product Description

The Proto RIG is an air-cooled SHA-256 ASIC miner from Proto for Bitcoin (BTC). This 819 TH/s version is listed at 12,000 W, an efficiency of 14.65 J/TH.

As an air-cooled machine it relies on its own fans, so it needs a steady supply of cool intake air and somewhere for the hot exhaust to go. Plan ventilation and noise before the unit arrives.

Before you order

• Power: 12,000 W. A load this size needs industrial power planning; check the rated input voltage and phase of the unit before you order.
• Noise: listed at 80 dB, so plan a space away from living areas.
