Buy the Bitaxe Supra: ASIC performance at the lowest entry-level price
Are you ready for real ASIC hashrate but don’t want to spend €129 on a Bitaxe Gamma just yet? For €65, the Bitaxe Supra offers ASIC-level performance via the BM1368 chip and the trusted AxeOS web interface. It’s the fourth generation of the Bitaxe project, the direct predecessor to the Gamma, and for anyone who just wants to get started with ASIC-level bitaxe Supra, this is the most affordable entry-level model.
The Bitaxe Supra achieves a hashrate of approximately 700 GH/s with a power consumption of approximately 15 watts. You can get more out of it by overclocking, at your own risk. That’s millions of times more than the NerdMiner T-Display S3, at one and a half times the price. It’s the logical first step into ASIC mining for people who want to upgrade from the NerdMiner but aren’t ready to make the full Gamma investment just yet.
The fourth generation of Bitaxe: robust, open source, affordable
The BM1368 chip in the Supra originates from the Antminer S21 (not the S21 Pro, which has the newer BM1370). The Gamma is therefore the successor with a more efficient chip and higher hashrate. But for small-scale home mining, that generational difference matters less than you might think. The Supra offers solid ASIC hashrate at low power consumption, and the open-source philosophy and AxeOS interface are completely identical to the Gamma.
BitcoinStuffStore is an official EU reseller of Bitaxe, so when you buy the Supra, you’re purchasing from a Dutch company with an EU warranty, not through a middleman on a marketplace.
Supra vs. Gamma vs. NerdMiner: The Numbers
| Model | Hashrate | Chip | Power consumption |
|---|---|---|---|
| NerdMiner T-Display S3 | about 77 KH/s | ESP32-S3 | 5 to 10 W |
| Bitaxe Supra | about 700 GH/s | BM1368 | about 15 W |
| Bitaxe Gamma | about 1.1 TH/s | BM1370 | about 18 W |
| Bitaxe Gamma Silent | about 1.1 TH/s | BM1370 | about 18 W |
| Nerdaxe Gamma | about 1.1 TH/s | BM1370 | about 18 W |
| Bitaxe Naja Duo | about 4.4 TH/s | 2x BM1373 | about 42 W |
| NerdQaxe++ | about 4.8 TH/s | 4x BM1370 | about 76 to 80 W |
| NerdOctaxe Gamma | approximately 9.6 TH/s | 8x BM1370 | circa 160 W |
The Supra delivers 700 GH/s for €65. The Gamma delivers 1.1 TH/s for €129. Per terahash, the Gamma is more efficient, but if your budget is currently €65, the Supra still gives you a working solo miner ASIC with an identical software experience. If you want to upgrade later, the Bitaxe Gamma the obvious next step. If you want to start even smaller, the NerdMiner T-Display S3 for €39 the start option without ASIC.

Just like the Gamma, the Supra is fully open source and part of the OSMU project. The schematics, PCB files and firmware are publicly available on GitHub. You do not depend on a manufacturer that can shut down its cloud services. The hardware is yours, the firmware is yours. If you are going to earn sats, keep them safe with a Hardware Wallet. The full range is on the Solo Miners category.
Bitaxe is an open-source project from the OSMU community. You can find the designs, firmware and documentation on the official project site bitaxe.org.
Around 15 watts, comparable to an energy-efficient LED bulb. Suitable for 24/7 use without a significant impact on the electricity bill.
