Product Overview

The Avalon Q 90T is a compact, energy-efficient Bitcoin (BTC) SHA-256 ASIC miner from Canaan — the company that invented the first commercial Bitcoin ASIC miner. Delivering 90 TH/s at approximately 1,670W, the Avalon Q carves out a distinct niche in the SHA-256 market: mid-tier hashrate at genuinely low power draw, combined with near-silent operation that makes it practical for home mining rooms, offices, and spaces where industrial-grade noise is not acceptable.

The Avalon Q distinguishes itself from most commercial Bitcoin ASICs by prioritising noise reduction and power accessibility alongside reasonable hashrate output. At 1,670W, it draws far less power than flagship miners like the S21 Pro (3,510W) or S21 XP (3,645W), making it significantly more manageable for South African home operators from both an electrical infrastructure and load-shedding resilience standpoint. Its quiet cooling system makes it one of the few Bitcoin ASICs that can operate in a home office or spare room without requiring acoustic isolation.

For South African Bitcoin mining enthusiasts who want meaningful SHA-256 hashrate without the electrical and acoustic demands of flagship hardware, the Avalon Q 90T represents a well-considered compromise between hashrate output, energy consumption, and operational practicality.

Key Features

• 90 TH/s SHA-256 Hashrate (±5%): Solid mid-tier Bitcoin mining contribution. While lower than flagship commercial miners, 90 TH/s provides meaningful pool contributions and consistent earnings proportional to network share.
• 1,670W Power Consumption: Significantly lower absolute power draw than most comparable SHA-256 miners. At 1,670W, the Avalon Q is accessible for South African operators with a dedicated 20A circuit — well below the 32A threshold required by 3,000W+ units.
• Power Efficiency ~18.6 J/TH: While not as efficient as the latest 5nm flagship miners, the Avalon Q’s efficiency is competitive for its price tier and power class, representing a practical balance between cost, hashrate, and electricity consumption.
• Near-Silent Operation: The Avalon Q’s cooling system is significantly quieter than conventional high-speed ASIC fans. This is one of its defining advantages — suitable for home rooms, home offices, or semi-residential environments where ASIC noise would otherwise be prohibitive.
• Compact Form Factor: Smaller than full-rack commercial miners, the Avalon Q is manageable for home deployment without industrial rack infrastructure.
• Ethernet and Wi-Fi Connectivity: Supports both wired Ethernet and Wi-Fi for flexible home network integration — a practical feature for home miners who may not have Ethernet runs to every room.
• Included PSU: Ships with an appropriate power supply — plug in and begin mining without a separate PSU purchase.

Power & Installation Notes

The Avalon Q 90T draws approximately 1,670W continuously — a moderate power draw for an ASIC miner. In South Africa, a dedicated 20A single-phase circuit is the minimum recommended installation. This falls below the 32A threshold that larger miners require, making the Avalon Q more accessible from an electrical infrastructure perspective.

South Africa’s 230V / 50Hz grid supply is within the Avalon Q’s 200–240V input specification. The included PSU handles South African mains voltage directly. Wiring must comply with SANS 10142; engage a registered electrician for any new dedicated circuit installation. At 1,670W, circuit planning is important but far less demanding than for 3,000W+ flagship miners.

Load shedding resilience is one of the Avalon Q’s key advantages for South African home miners. At 1,670W, a 3 kVA inverter with a 5 kWh battery bank can sustain the Avalon Q for approximately 3 hours — covering Stage 2 load-shedding cycles. A 10 kWh battery extends this to approximately 6 hours, covering most Stage 4 scenarios. This makes the Avalon Q substantially more inverter-friendly than 3,000W+ flagship miners, where home inverter backup is generally not viable.

Noise levels are another key advantage. The Avalon Q’s low-noise design means it can operate in a home room without requiring acoustic treatment or soundproofing — a significant practical benefit for South African home miners.

Electricity Cost Context — South Africa

At Eskom’s approximate residential reference tariff of R2.80/kWh, the monthly electricity operating cost for the Avalon Q 90T is estimated as follows:

(1,670 ÷ 1,000) × 24 × 30 × 2.80 = R3,367.20 per month

This is an operating cost estimate only — not a profitability projection. Actual electricity tariffs vary by municipality and supply category. At approximately R3,367/month in electricity, the Avalon Q sits at roughly half the electricity cost of a 3,500W+ flagship miner — a meaningful difference for home miners on residential tariffs. Always verify your specific electricity rate before modelling Bitcoin mining economics.

Ideal Use Cases

• Home Bitcoin mining without industrial noise: The Avalon Q’s near-silent operation makes it one of the few Bitcoin ASICs that can realistically operate in a home room without causing daily disruption. Ideal for South African home miners who want SHA-256 mining in a spare bedroom, home office, or garage.
• Mid-range hashrate with manageable power: For South African operators who want meaningful Bitcoin mining hashrate but cannot or prefer not to run 3,000W+ hardware, the Avalon Q provides a sensible mid-point.
• Load-shedding-conscious Bitcoin miners: The Avalon Q’s 1,670W draw makes it one of the most practical Bitcoin ASICs for load-shedding resilience — supportable on a well-sized home inverter for several hours per outage.
• Fleet diversification with low noise profile: Mining operators who want to add a low-noise Bitcoin mining unit to a space where full-size commercial ASICs would be disruptive will find the Avalon Q fits this role effectively.

Frequently Asked Questions

Does the Avalon Q 90T work on South African power?
Yes. South Africa’s 230V / 50Hz grid is within the Avalon Q’s 200–240V input range. The included PSU handles South African mains voltage directly. A dedicated 20A circuit is recommended.

How does the Avalon Q 90T compare to flagship miners like the S21 Pro?
The S21 Pro 234Th offers more than twice the hashrate at 3,510W — far more absolute Bitcoin mining power, but also roughly double the electricity cost and significantly higher noise levels. The Avalon Q 90T is the quieter, lower-power option for operators where home mining practicality is a priority over maximum hashrate.

Can the Avalon Q run during load shedding?
Yes — at 1,670W, a 3 kVA inverter with a 5 kWh battery can sustain the Avalon Q for approximately 3 hours. A 10 kWh battery extends this to approximately 6 hours. This makes it one of the better Bitcoin ASICs for load-shedding resilience in South African home setups.

What pool should I use with the Avalon Q 90T?
Major SHA-256 Bitcoin pools include Foundry USA, AntPool, ViaBTC, F2Pool, and Binance Pool. The Avalon Q supports both Ethernet and Wi-Fi connectivity, making it straightforward to configure on a home network.

Is the Avalon Q 90T suitable for a home office or spare room?
Yes — the near-silent operation is one of the Avalon Q’s defining selling points. While not completely silent, it operates at noise levels that most people find acceptable in a home room. It’s one of the few Bitcoin ASIC miners that doesn’t require acoustic isolation for residential deployment.
