Bitaxe Hex 701 Review
The Bitaxe Hex 701 (aka Bitaxe SupraHex 701) is an open‑source, multi‑chip SHA‑256 miner designed for desks and small rooms. It combines 6 × BM1368 ASICs and typically delivers ~4.2 TH/s at ~90 W (stock) with a Wi‑Fi web UI. Think of it as a quiet hobby “mini‑rig”: much more throughput than single‑chip boards, yet tame enough for apartments.
Pros:
- Multi‑chip throughput in a desk form factor — ~4.2 TH/s @ ~90 W (≈ ~21–22 J/TH).
- Open‑source design with an active community; transparent and mod‑friendly.
- Wi‑Fi + web UI onboarding (captive portal) — quick to get hashing.
- Low daily cost for continuous operation compared to heater‑class miners.
Cons:
- Not ROI‑focused; treat solo as lottery‑style — pools give steadier payouts.
- Noise depends on fan & room (~35–45+ dB typical); placement matters.
- Wi‑Fi‑only on most kits (no native Ethernet); use a small bridge for wired‑like stability.
If you want ultra‑low‑power learning (~20–35 W), see Bitaxe Gamma. If you prefer a plug‑and‑play mini‑heater with similar TH/s but more warmth, compare with Avalon Nano 3S. Browse all home‑friendly miners in our SHA‑256 index → https://homeminerhub.com/reviews/sha256/
Key Takeaways
- Throughput & efficiency: ~4.2 TH/s @ ~90 W → ~21.4 J/TH (lower is better; What is J/TH?).
- Noise: roughly mid‑30s to mid‑40s dB depending on fan/room — see decibel primer.
- Best use‑cases: pool mining, learning, and solo‑lottery experiments without server‑room noise.
- Networking tip: close to your AP or use an Ethernet bridge to cut stale shares.
- Compare: Gamma for silence/DIY; Nano 3S for heat + mining.
Technical Specifications
| Item | Spec |
|---|---|
| Also called | Bitaxe SupraHex 701 |
| Algorithm | SHA‑256 (BTC, BCH, etc.) |
| ASICs | 6 × BM1368 (multi‑chip) |
| Hashrate (typical) | ~4.2 TH/s |
| Power (typical) | ~90 W @ wall (kit/ambient variance) |
| Efficiency (math) | ~21–22 J/TH (e.g., 90 W / 4.2 TH/s → ~21.4 J/TH) |
| Networking | Wi‑Fi (web UI); captive portal onboarding |
| Display | Small status screen on many kits (varies by batch) |
| Power input | 12 V DC, ≥ 6–8 A recommended — see power supply basics |
| Cooling | 80 mm fan (varies by kit); aftermarket quiet fans are common |
| Dimensions / Weight | Compact desktop footprint, ~400 g class |
Plain‑English examples: 4.2 TH/s ≈ 4.2 trillion SHA‑256 guesses per second. 90 W is like a bright desk lamp or a mini‑PC under light load. 21 J/TH means 21 joules per trillion hashes.
Performance, Noise & Heat
Expect the Hex 701 to stabilize near ~4.2 TH/s after warm‑up, pulling ~90 W at the wall (PSU quality and mains can shift a few watts). Noise is a soft whoosh; perceived tone depends on room acoustics and the fan model. If you notice a hum, rotate the unit a few centimeters, change the surface, or swap for a quiet 80 mm fan.
Heat output (rule‑of‑thumb): 1 W ≈ 3.412 BTU/h → 90 W ≈ ~307 BTU/h — a gentle warmth near the device, not a heater. If you want meaningful room heat, see Avalon Nano 3S (140 W).
Electricity cost examples (24 h, continuous @ 90 W):
- €0.10/kWh → ~€0.22/day (~€6.6/month)
- €0.20/kWh → ~€0.43/day (~€13.0/month)
- €0.30/kWh → ~€0.65/day (~€19.5/month)
Formula: kWh = (Watts ÷ 1000) × hours. See kilowatt‑hour.
Setup & Pooling (quick start)
- Place & power: Keep the rear exhaust clear. Use a quality 12 V DC PSU (≥ 6–8 A). Short, thick DC cables reduce voltage drop.
- First boot: Power on; join the miner’s SSID (e.g., Hex701_XXXX). A captive portal guides you to the web UI.
- Network: Enter Wi‑Fi credentials. If Wi‑Fi is weak, use a small Wi‑Fi‑to‑Ethernet bridge for wired‑like stability.
- Pool or solo: New users should start with a mining pool (steady sats). Solo is lottery‑style; try https://ckpool.org or https://solopool.org carefully.
- Example pool string:
stratum+tcp://pool.example.com:3333
Username:bc1q...youraddress.worker1(Bech32 format)
Password:x(or as required by your pool). - Verify & monitor: After 5–10 minutes, hashrate stabilizes. Watch Rejected/Stale shares; if they rise, improve signal or switch to an Ethernet bridge.
Firmware & community: Development lives on Bitaxe GitHub. Retailer pages sometimes include setup videos and updated profiles.
Who Should Buy the Bitaxe Hex 701?
- Beginners & tinkerers wanting more TH/s than single‑chip boards without jumping to loud heater‑class miners.
- Apartment users looking for a compact, Wi‑Fi‑first miner for 24/7 operation.
- Solo‑curious miners who understand the lottery nature of solo payouts.
If you need the quietest possible learning device, try Bitaxe Gamma. If you want smoother UX with heater‑level warmth, see Avalon Nano 3S.

Verdict
Bitaxe Hex 701 hits a sweet spot: multi‑chip throughput in a body small enough for a desk, ~4.2 TH/s at ~90 W, and open‑source transparency. Treat it as a quiet, compact, pool‑friendly miner with optional solo‑lottery fun. If you want ultra‑low power (Gamma) or heater‑plus‑miner comfort (Nano 3S), those picks may suit you better.
FAQ's
Is Hex 701 profitable?
Generally no at residential tariffs; it’s about learning + sats + experiments.
How loud is it?
Depends on the fan and your room. Expect a soft whoosh; placement and surfaces can change the tone.
Can I solo‑mine with it?
You can, but solo is lottery—payout only if you find a block. Prefer a pool for steady payouts.
Does it include a PSU?
Some sellers include a 12 V adapter; others ship head‑unit only. Check bundle contents.
Ethernet support?
Most kits are Wi‑Fi‑only. If you need wired‑like stability, use a small Wi‑Fi‑to‑Ethernet bridge.
