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.
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 |
