Product Overview

The BitAxe Gamma 601 is an open-source, ultra-compact SHA-256 solo Bitcoin miner delivering approximately 1.2 TH/s at just 20–22W. Part of the community-developed BitAxe project, the Gamma 601 is built around the Bitaxe architecture using Bitmain’s BM1370 ASIC chip (the same chip used in the S21 Pro series) — delivering legitimate SHA-256 mining capability in a device smaller than a paperback book.

The BitAxe Gamma series is the evolution of the BitAxe open-source miner project, building on previous BitAxe Ultra and Max models with improved efficiency using the BM1370 chip. The “601” designation refers to the Gamma variant with the BM1370 chip configuration. Unlike commercial ASIC miners, the BitAxe Gamma 601 is open-source hardware — schematics, firmware, and software are all publicly available, making it popular with hobbyists, educators, and cryptocurrency enthusiasts who want to understand mining at the hardware level.

For South African Bitcoin enthusiasts, the BitAxe Gamma 601 offers a genuinely unique proposition: a legitimate Bitcoin (BTC) mining device that draws just 20W, runs on any USB-C power bank or 5V adapter, is completely silent, and can operate continuously through South African load shedding with virtually any backup power source. While 1.2 TH/s is a modest hashrate for Bitcoin mining economics, the device delivers real BTC mining participation at minimal cost and maximum convenience.

Key Features

• 1.2 TH/s SHA-256 Hashrate: Real Bitcoin mining hardware at hobbyist scale. The BM1370 ASIC chip delivers genuine SHA-256 proof-of-work at 1.2 TH/s — significantly more than earlier BitAxe models. While modest for pool economics, it’s real hashrate contributing to Bitcoin’s security.
• 20–22W Power Consumption: Draws less power than a single LED light bulb. Run from any USB-C power source, USB wall adapter, or 5V power supply without any electrical modifications whatsoever.
• BM1370 ASIC Chip: Uses the same chip architecture as the Bitmain Antminer S21 Pro series — a cutting-edge 5nm ASIC delivering exceptional efficiency per core. The BM1370 is what gives the Gamma 601 its leading efficiency among open-source Bitcoin miners.
• Open-Source Hardware and Firmware: All schematics, PCB designs, firmware (AxeOS), and software are open-source. Flash custom firmware, modify the design, contribute to the project, or simply enjoy knowing exactly what your mining hardware does.
• Completely Silent: No fans, no moving parts. The Gamma 601 is passively or minimally cooled and operates in complete silence — suitable for any home environment, bedroom, desk, or living space.
• Wi-Fi Connectivity: Connects to your home Wi-Fi network for pool configuration, monitoring, and firmware updates through the AxeOS web interface. No Ethernet cable required.
• Compact and Portable: Fits in a shirt pocket. Can be taken anywhere with a USB power source — truly portable Bitcoin mining.

Power & Installation Notes

The BitAxe Gamma 601 draws just 20–22W from a standard USB-C 5V power source. This means zero special electrical planning is required — plug it into any USB-C wall adapter (5V/3A or higher) or USB power bank and it will run. No dedicated circuit, no registered electrician, no electrical modifications whatsoever. A phone charger can power it.

South Africa’s 230V / 50Hz mains power is completely irrelevant for direct installation considerations — the BitAxe Gamma 601 operates from USB-C 5V input, which is supplied by any standard USB power adapter. All USB-C wall adapters sold in South Africa are compatible with the Gamma 601’s power requirements.

Load shedding is essentially a non-issue for the BitAxe Gamma 601. At 20W, a standard 5 kWh home battery backup can run the Gamma 601 for over 200 hours straight. Even a basic USB power bank (20,000 mAh = ~100Wh) can power the Gamma 601 for approximately 4–5 hours. The device can also run from a car’s USB outlet, a laptop USB port, or any small solar panel with USB output. This makes it one of the most load-shedding-resilient mining devices available in South Africa.

Operating temperature: the Gamma 601 generates minimal heat and operates at room temperature in most environments. Keep it in a reasonably ventilated location (not sealed in an airtight container) but no special cooling infrastructure is needed.

Electricity Cost Context — South Africa

At Eskom’s approximate residential reference tariff of R2.80/kWh, the monthly electricity operating cost for the BitAxe Gamma 601 is estimated as follows:

(21 ÷ 1,000) × 24 × 30 × 2.80 = R42.34 per month

This is an operating cost estimate only — not a profitability projection. At approximately R42/month, the Gamma 601 has the lowest electricity operating cost of any Bitcoin mining device. The economics of Bitcoin pool mining at 1.2 TH/s are modest, but the experience, educational value, and participation in the Bitcoin network come at virtually zero incremental electricity cost. For solo miners, the possibility (however remote) of solving a Bitcoin block and earning the full block reward makes the electricity cost completely inconsequential.

Ideal Use Cases

• Solo Bitcoin mining: The BitAxe Gamma 601’s primary use case for many owners is solo mining — pointing the hashrate at a solo pool like CK Pool’s solo.ckpool.org for the lottery-like chance of solving a Bitcoin block and earning the full reward. At 1.2 TH/s the odds are remote, but it’s real SHA-256 work.
• Bitcoin education and DIY enthusiasts: The open-source hardware and firmware make the Gamma 601 ideal for learning about Bitcoin mining, ASIC hardware, and cryptocurrency proof-of-work at a hands-on level without a large investment.
• Collectors and enthusiasts: Building and running a BitAxe miner is a badge of honour in the Bitcoin hobbyist community. The Gamma 601, with its S21 Pro ASIC chip, is the current flagship of the open-source miner space.
• Load-shedding-immune mining: At 20W, the Gamma 601 is the most load-shedding-resilient Bitcoin miner available — it runs for days on a basic USB power bank, making it uniquely suited to South African home miners who want continuous participation in Bitcoin mining regardless of grid status.

Frequently Asked Questions

Does the BitAxe Gamma 601 require any special electrical setup in South Africa?
No. The Gamma 601 runs from a standard USB-C power adapter. Plug into any USB-C wall charger or power bank. No dedicated circuit, no electrician, no electrical modifications needed — just a USB-C port.

What is the difference between the BitAxe Gamma and the Bitaxe Supra/Ultra?
The BitAxe Gamma 601 uses the BM1370 chip (from the S21 Pro series), making it the most efficient BitAxe variant to date. Earlier BitAxe models (Ultra, Max, Supra) use older ASIC chips with lower efficiency. The Gamma 601 is the current flagship open-source Bitcoin miner.

Can I pool mine with the Gamma 601?
Yes. The AxeOS firmware supports major SHA-256 pools including public-solo.ckpool.org, Braiins Pool (STRATUM V2), and others. For pool mining, configure your preferred pool’s stratum URL in the AxeOS web interface accessible via your home Wi-Fi network.

How does the Gamma 601 handle load shedding?
Exceptionally well. At 20W, a 20,000 mAh USB power bank can power the Gamma 601 for approximately 4–5 hours — covering standard load-shedding stages. A 5 kWh home battery system provides over 200 hours of continuous runtime. It’s essentially load-shedding-immune.

Is the BitAxe Gamma 601 genuinely mining Bitcoin?
Yes. The BM1370 ASIC performs real SHA-256 proof-of-work, submitting valid shares to your configured Bitcoin mining pool. The hashrate is genuine, though modest at 1.2 TH/s relative to the total Bitcoin network. Earnings from pool mining will be proportionally small — this device is primarily for participation, education, and the solo mining lottery experience.
