Overview
The Bitmain Antminer DR7, launched in July 2024, is Bitmain’s high-performance ASIC miner for SCPrime (SCP) mining using the Blake2B-SCP algorithm. With a powerful hashrate of 127 TH/s and a power consumption of approximately 2730 W, it offers efficiency around 21.5 J/TH—making it one of the most capable and optimized machines for the SCPrime storage network.
About the Coin: SCPrime (SCP)
SCPrime is a decentralized cloud storage network that enables secure, encrypted file storage using blockchain-powered Proof-of-Work consensus. It supports long-term Web3 infrastructure with a utility-driven model.
Built on the Blake2B-SCP algorithm, SCPrime rewards miners for securing data transactions across the network, supporting real-world use cases for decentralized storage. The project has positioned itself as a serious alternative to centralized cloud providers.
SCPrime combines practical utility with mining rewards, making it appealing for long-term mining strategies — especially as demand for decentralized file storage grows globally.
Exterior Design
The DR7 features Bitmain’s industrial air-cooled chassis, measuring 400 × 195.5 × 290 mm with a net weight of 16.1 kg. Its robust, metal build is similar to the L7 but internally optimized for Blake2B-SCP operation. Built for endurance in high-load environments, the unit includes optimized heat sinks and layout for consistent long-term performance.
Power Supply & PSU Details
The DR7 comes with a high-efficiency built-in APW171417B V1.00 power supply that supports 220–240 V AC input at 50–60 Hz, drawing approximately 20 A at full load.
It includes a 2x C13 Plug (20A) optimized for stable performance during long-term mining operations.
Cooling System
The DR7 is cooled by 4x high-performance fans, arranged in a front-to-back airflow configuration for maximum ventilation. These fans actively maintain temperature stability even under continuous, high-density hashing.
