AvalonMiner 721 Power Connectors

With the AvalonMiner 721 we upgraded the number and quality of power connectors.

The AvalonMiner 721 is ROQ Solid. In the AvalonMiner 721 we upgraded the number and quality of power connectors to increase efficiency and reliability of the AvalonMiner 721. The front face of the AvalonMiner 721 now has “8-on-front” 6-pin female power connectors so that an operator connects 8 of a power supply unit’s 6-pin male power connectors to an AvalonMiner 721. In our tests, Canaan has seen a 5-8 % increase in efficiency in our latest generation miner by moving from 4 power connectors to 8. Also, by connecting 8-on-front power connectors with quality cables, an AvalonMiner 721 should run even more consistently and reliably.
