About AvalonMiner 921
Like its predecessors, AvalonMiner 921 comes with a simple build and an aluminum case that protects the miner from dust. The AvalonMiner has a dimension of 150 x 136 x 370mm and weighs 4.8kg per unit. In appearance, the AvalonMiner 921 has a different design from older models. This miner comes with 7nm Application-Specific Integrated Circuits (ASIC) chips, ensuring productivity and efficiency. The chipboards have 88 of such chips, giving the miner an impressive computing hash rate of 20Th/s and consumes 1700W of power.
Specifications
The AvalonMiner 921 is also known as a Reliable Open Miner (ROQ), which comes with 104 x A3210HP 7nm chips. This device produces a hash rate of 20Th/s. By connecting the AvalonMiner Controller (sold separately) to an AvalonMiner USB Converter (AUC3), you can connect up to 5 different miners. To increase profitability, connect up to 20 AvalonMiner 921s, which will give you an accumulated hash rate of 400Th/s. If you control a large installation of AvalonMiners (like in a mining farm), you can get a developed AvalonMiner Management System, which helps you manage thousands of AvalonMiner devices conveniently.
The AvalonMiner consumes 1800W at 25°C with a Power Supply Unit (PSU) efficiency of 220V AC. The device has a power efficiency of 0.089J/Gh/s. The AUC is required for this product and is shipped with the controller. The AUC3 is a 5 pin cable suitable for Avalon A7, A8, A9 series. AvalonMiner has mining pools like Slushpool, AntPool, Poolin, etc., associated with it.
