What is the Antminer S21 Pro+?
The Antminer S21 Pro+ from Bitmain marks a notable leap forward in Bitcoin mining technology, prioritizing both efficiency and performance. With a hash rate of up to 234 TH/s and an efficiency of up to 14 J/TH with Braiins OS (15 J/TH with Bitmain Stock OS), the Antminer S21 Pro+ demonstrates significant advancements. Developed in partnership with TSMC and featuring cutting-edge 5-nm chips, this model boasts up to a 40 % improvement in efficiency over its predecessors, the S19 series. This exemplifies Bitmain's ongoing commitment to refining mining hardware for superior performance and lower power consumption.
Efficiency with Braiins OS
The J/TH figures provided are reference values from Braiins and relate to undervolted operation under optimal conditions. Braiins itself describes these figures as best measured results achieved at the respective optimal power target. Due to natural chip variance, each unit performs slightly differently, while ambient temperature and cooling can further affect the results. These figures are therefore intended as a guide only and do not represent a guaranteed specification.
Power connection
The C20-P13 power cable is not included. To connect the miner to the mains, you need a suitable, correctly rated power cable, or a qualified electrician can make the connection for you.
Info: With a rated output of 3510 W, the Antminer S21 Pro+ can theoretically be operated from conventional sockets with a capacity of 3680 W. In order to ensure safety and optimum functionality, especially in continuous operation, we recommend clarifying the connection on site with a qualified electrician.
