Meet the Avalon Q – 90 TH/s of SHA-256 grunt

Looking for a sensible way into Bitcoin mining without the jumbo electricity bill? The Avalon Q hits a sweet spot: solid 90 TH/s hash rate, sipping just 1.67 kW, and whisper-quiet enough to park in a spare room. I’ve had one humming beside a chest freezer all week and barely noticed the fan spin-ups.

At-a-glance specs

• Hashrate: 90 TH/s ± 5 %

• Power draw: 1 674 W @ 25 °C

• Efficiency: 0.019 J/GH

• Algorithm / coin: SHA-256 – Bitcoin

• Noise level: ~50 dB at full tilt

• Cooling: Dual-fan air-cool

• Size & weight: 455 × 130 × 440 mm, 10.5 kg

• Warranty: 6 months, handled by Sell Your PC

• Extras: Gigabit Ethernet, low-rpm “quiet” fans

• Ideal for: First-time miners & anyone chasing low capex per TH

  Why miners pick this rig

  1. Respectable efficiency for the rand. At ~19 J/TH you’re edging close to the big boys without splashing out on hydro gear.

  2. Tame acoustics. 50 dB is office-fan territory, not jet-engine scream.

  3. Plug-and-play firmware. Standard Avalon dashboard – no weird SSH gymnastics.

  What it’s like to live with

  Power wise, you’ll need a single 16 A circuit (C20 plug works). Noise is a steady whoosh; I’d stash it in a scullery or garage, but it won’t rattle dishes. Setup took me ten minutes – DHCP picked it up, changed the pool URL, done. Temperature stayed under 70 °C in a Joburg winter evening; I reckon it’ll hash happily down to about 10 °C, but I’ve not tested below that.

 

Simple setup steps

1. Unbox, check for transit dings.

2. Plug C20 to a 16 A breaker, Ethernet to your router.

3. Power on; find the IP in your DHCP table.

4. Log in (admin / admin), set pool & wallet.

5. Hit “Save & Apply”. Sit back, watch shares roll in.
