Notes
(1) The hashrate value, power on wall, and power efficiency on wall are all typical values. The actual hashrate value fluctuates by ±3%, and the actual power on wall and power efficiency on wall fluctuate by ±5%.
(2) Caution: Wrong input voltage may cause server damaged.
(3) The noise is loudest when the fan is under maximum RPM(rotation per minute).
(4) When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.

Jasminer X4-QZ
Jasminer X4-QZThe Jasminer X4-QZ is engineered as an accessible and reliable miner for Ethereum Classic (ETC) enthusiasts and small-scale operators. Powered by the EtHash algorithm and tuned for efficient hash production, the X4-QZ delivers an 840MH/s hashrate while keeping power consumption around 340W thanks to its integrated power supply unit (PSU). The inclusion of the PSU makes setup straightforward — simply mount, connect power and Ethernet, and start mining.
Its compact form factor and quiet cooling fans ensure that the miner runs smoothly with minimal acoustic disturbance, making it ideal for residential environments and small mining farms. The unit supports all major ETC mining pools and integrates easily with popular mining monitoring tools for real-time performance tracking.
Jasminer's Legacy & Product Line
Jasminer is a specialized ASIC manufacturer focused on energy-efficient, low-noise mining hardware for memory-intensive algorithms. Unlike brands that prioritize maximum power draw and industrial-scale deployments, Jasminer has consistently positioned itself around efficiency, stability, and accessibility, making its miners especially popular among home miners, small farms, and users operating in power-constrained environments. The brand gained industry recognition through its EtHash miners, where performance per watt and long-term reliability are critical.
Jasminer’s product strategy emphasizes quiet operation, compact form factors, and optimized airflow, addressing real-world deployment challenges such as heat management, noise limits, and electrical stability. This approach aligns well with Ethereum Classic mining, where sustained efficiency often matters more than raw peak output.
Jasminer Product Line Overview
The X-Series represents Jasminer’s core ASIC lineup for the EtHash algorithm, designed specifically for Ethereum Classic (ETC) mining:
X4 / X4-Q Series
Early generation EtHash miners that established Jasminer’s reputation for low power consumption and stable performance.
X16 Series (X16-Q, X16-Q Pro)
A refined generation delivering higher hashrates while maintaining quiet operation and strong efficiency. These models are widely adopted for home and small-scale ETC mining due to their balanced design.
Across its product line, Jasminer focuses on incremental efficiency improvements rather than aggressive power scaling, ensuring miners remain practical to operate over longer market cycles. This philosophy makes Jasminer hardware a reliable choice for miners seeking predictable performance, manageable operating costs, and long-term usability.
X4-QZ vs X4-Q vs X16-Q
The X4-QZ stands out as a plug-and-play ETC miner with included power supply, making it especially suitable for beginners and home miners who want a simplified setup. Compared with the standard X4-Q, it offers easier deployment. The X16-Q, with higher hashrate, is a stronger choice for users seeking more performance.
| Feature | X4-QZ | X4-Q | X16-Q |
|---|---|---|---|
| Hashrate | 840 MH/s | 1040 MH/s | 1950 MH/s |
| Power | ~340W | ~360W | ~600W |
| PSU | Included | No (requires PSU) | No (requires PSU) |
| Ideal Use | Plug-and-Play Entry | Entry / Home | Mid-Tier Home |
| Noise | Low | Low | Low |
