Nexus S1-02 | 10 TH/s

The Nexus S1-02 is the big brother of the Nexus S1-01: the same device with colour display, Wi-Fi, Ethernet and stand, but with four BM1373 ASICs by Bitmain instead of two. It delivers around 10 TH/s on roughly 150 W, about 15 J/TH. It is cooled by a black AXP90 by Thermalright, and a 12 V power supply with 200 W provides the power.

It is run through an ESP32-S3 with the open-source NMAxe firmware in your browser. It joins your home network over 2.4 GHz Wi-Fi or an Ethernet cable. You set pool, worker and Bitcoin address yourself; you need no account and no cloud. The Nexus S1-02 is available to pre-order and is expected to ship from 10 December 2026.

The stated figures are around 10 TH/s on roughly 150 W. That is what we work with too, about 15 J/TH. Actual values depend on the individual unit, the room temperature and the settings.

• Hash rate: around 10 TH/s.
• Power draw: roughly 150 W.
• Efficiency: about 15 J/TH.
• Chips: four BM1373 by Bitmain.

• Chips: four instead of two BM1373.
• Hash rate: around 10 instead of around 5 TH/s, twice as much.
• Power: roughly 150 instead of roughly 80 W.
• Efficiency: about 15 instead of about 16 J/TH.
• Power supply: 12 V / 16.7 A (200 W) instead of 12 V / 10 A (120 W).
• The same: colour display, Wi-Fi, Ethernet and stand.

The Nexus S1-01 is the entry model with half the hash rate. The S1-02 doubles the hash rate and needs almost twice the power for it, so per TH/s it is slightly more frugal.

The Nexus S1-02 carries a black AXP90 by Thermalright, a low-profile CPU cooler from the PC world. Heat pipes move the heat from the chips into a dense fin stack, and a 92 mm fan pushes air down through it. The firmware sets the fan speed by temperature.

Board and cooler sit at an angle in a black stand with a honeycomb structure. That keeps the display easy to read and lets air flow freely through the cooler.

The colour display shows the values that matter for mining: hash rate, best difficulty, input and core voltage, current, power, efficiency in W/TH, temperature, fan speed and the IP address on your home network. For a quick look you do not need to open a browser.

Out of the box it runs the NMAxe firmware by the NMMiner team, an open-source offshoot of the Bitaxe firmware under GPL-3.0. Its web interface in the style of AxeOS shows statistics, manages several miners on a swarm page and offers the performance profiles ECO, Normal and Turbo. If you like to fine-tune yourself, you set clock and core voltage by hand. Updates are installed through the web interface.

The Nexus S1-02 joins your home network over 2.4 GHz Wi-Fi or through its Ethernet port (RJ45). Wired to the router, the connection does not depend on Wi-Fi range.

The Nexus S1-02 runs on 12 V. The box contains a power supply with 12 V and 16.7 A, or 200 W, and an EU power cord. That leaves headroom above the roughly 150 W of the miner, and all you need is a socket.

• Chips: four BM1373 instead of six BM1370.
• Hash rate: around 10 TH/s; the Gamma Hex 1300 reaches around 8.4 out of the box and around 10.5 TH/s overclocked.
• Power: roughly 150 W, as much as the Gamma Hex 1300 out of the box. Overclocked, it needs roughly 200 W.
• Cooling: AXP90 air cooler instead of liquid cooling.
• Firmware: NMAxe instead of AxeOS, both open source and used in the browser.

The Bitaxe Gamma Hex 1300 is the Bitaxe with liquid cooling and AxeOS. At roughly 150 W, the Nexus S1-02 gets about a fifth more hash rate than the Gamma Hex out of the box, with no liquid loop at all.

Running around the clock, the Nexus S1-02 uses about 110 kWh a month. What that costs at your tariff and how hash rate and power compare is worked out by the mining calculator with your own figures.

All of those roughly 150 W end up as heat in the room, so in winter the miner helps heat it. Stand it in the open, let the fan draw air freely, and do not put it in a closed cabinet.

Every hash is a ticket in the same draw the large farms take part in. If your Nexus S1-02 finds the matching block, the full reward of currently 3.125 BTC plus transaction fees goes to your own address, undivided and with no provider in between. At around 10 TH/s you hold about eight times as many tickets as with a Bitaxe Gamma. That does not change the order of magnitude of the chance; solo mining stays a matter of luck. How small it is, is shown in the article on the odds of finding a block.

Our solo pool pool.bitaxe.de runs in Frankfurt and charges a 0 % fee. The principle is explained in Bitcoin solo mining.

The Nexus S1-02 is sold as a pre-order. Shipping is expected to start on 10 December 2026, and orders go out in the order they were placed. You secure a unit from the first delivery, but you will have to wait until December for it.

Power, your home network and a browser are all you need for setup. Power supply and EU power cord are in the box.

For everyone who wants around 10 TH/s at home without a liquid loop and without a loud industrial machine. One device, one power supply, one display and one web interface.

It is less of a fit on a tight budget: the Nexus S1-01 offers the same technology with half the hash rate. And if you want to mine as quietly as possible in the bedroom, a Bitaxe Gamma serves you better.

Four BM1373 chips, around 10 TH/s at roughly 150 W, a black AXP90 cooler, Wi-Fi and Ethernet and a display with all the key values: the Nexus S1-02 gets ten terahashes out of one compact device.
