Asic Miner R4

The Antminer R4 is a legacy Bitcoin ASIC miner that holds a unique place in mining history as the first high-performance unit designed specifically for home use. While it revolutionized quiet mining at its 2017 launch, it is now considered an obsolete piece of hardware for profitable mining in 2026.

Product Overview & Specifications

Released in February 2017, the Antminer R4 was Bitmain's attempt to bring Bitcoin mining into the living room. It broke the traditional "shoebox" mold of ASIC miners, adopting a slim, stereo-component-like profile Bitcoinmagazine.

* Hashrate: 8.6 TH/s to 10 TH/s (with custom firmware like Braiins OS+) EbayAsicminervalue.

* Power Consumption: ~845W Asicminervalue.

* Noise Level: 52 dB, significantly lower than the 75-80 dB produced by industrial miners like the Antminer S9. This was achieved through a large tangential fan inspired by silent air conditioning units Bitcoinmagazine.

* Algorithm: SHA-256 (Bitcoin and Bitcoin Cash).

Current Market Trends & Insights (2026)

The market for the Antminer R4 has shifted from active production to a secondary legacy market focused on hobbyists and collectors.

1. 1Mining Profitability (Negative ROI): In 2026, the R4 is no longer profitable to run. At a standard electricity cost of $0.10/kWh, it loses approximately $1.76 per day Asicminervalue. Even at extremely low rates ($0.04/kWh), its efficiency of roughly 97 J/TH is vastly outperformed by 2026 flagship models like the Antminer S21 XP, which operates at a top-tier 13.5 J/TH D-Central.
2. 2Market Value & Availability:

* Operational Units: Used working units currently trade on platforms like eBay for $139 to $380, depending on condition and included accessories like the APW5 silent PSU Ebay.

* Non-Working/Parts: Units with dead hash boards sell for around $150 to collectors or those needing spare parts for legacy setups EbayEbay.

1. 3Shift to "Solo Mining" & Education: The R4's current market niche is driven by "Solo Mining" enthusiasts who run the hardware for the extremely small chance of finding a block personally, or by educators using the unit to demonstrate ASIC hardware due to its quiet operation and accessible internal design D-CentralBitcoinmerch.
2. 4Trend Toward Open-Source Home Mining: The market demand that the R4 once filled has largely migrated to small, ultra-quiet open-source devices like the Bitaxe, or high-efficiency home units like the Fluminer T3 (115 TH/s, 40 dB), which offer modern performance with the same "living room friendly" philosophy D-CentralD-Central.
