Canaan Avalon Nano 3S Bitcoin Miner 6TH/s 140W - Quiet Home Miner

Our review of the Canaan Avalon Nano 3S finds it best suited for hobbyist and small-scale miners who want a simple, low-noise entry into SHA-256 mining. The single biggest reason to consider this unit is its balance of a stable 6 TH/s hashrate with just 140W power draw, which keeps operating costs reasonable for a home or office setup. Setup is straightforward and it includes the original power supply, so buyers get a ready-to-run miner that fits on a desk or shelf without the bulky footprint or high heat of larger rigs.

Key Features

• Stable hashrate: A consistent 6 TH/s performance provides predictable mining output for Bitcoin, Bitcoin Cash, and similar SHA-256 coins.
• Low power consumption: At 140W the unit reduces electricity costs compared with larger miners, which is helpful for small-scale or home mining.
• Quiet operation: Designed with a low noise profile so it is practical for placement in apartments, studies, or shared office spaces.
• Original power supply included: The bundled Canaan PSU ensures reliable, compatible power delivery and plugs into standard U.S. outlets.
• Compact footprint: The small size makes it easy to fit on a desk or shelf and to integrate into modest rigs or solo setups.
• Simple connectivity: Ethernet support and straightforward plug-in setup make the miner accessible to beginners and experienced users alike.

Who It's For

The Avalon Nano 3S is aimed at hobbyist miners, crypto enthusiasts testing SHA-256 mining at home, and small-scale operators who need a compact, low-noise device. Its inclusion of the original power supply and simple Ethernet setup mean newcomers can get mining quickly without sourcing additional accessories.

It is not intended for large commercial farms or those chasing the absolute highest TH/s-per-dollar; miners who require extreme hashing density or advanced cooling should look at larger, industrial-grade models instead.

Pros & Cons

Pros

• Good power efficiency for a desktop miner, balancing 6 TH/s with 140W consumption.
• Quiet and compact, suitable for home or office environments where noise and space matter.
• Includes the original Canaan power supply for simpler, safer setup and consistent operation.
• Easy Ethernet connectivity supports both solo and pool mining without complex configuration.

Cons

• Not designed for large-scale commercial mining where higher total hashpower and rack density are priorities.
