Used units in stock in Prague – we have 4 machines at our shop at Rostovská 260/2b. Personal collection or shipping once payment has been received.
Supplied without a power supply
The miner is sold without a power supply. Choose one of the two power supplies for it and add it to your basket:
| Power supply | Noise | Price |
|---|---|---|
| Goldshell 1500 W power supply – original power supply for Goldshell BOX miners, can power several machines at once | quiet | 6 899 Kč |
| 2000 W 12 V mining power supply – server power supply, 230 V mains only | louder | 3 499 Kč |
For a flat, we recommend the quiet Goldshell power supply. The 2000 W server power supply is cheaper, but its fan is louder than the miner itself. Not sure which one to choose? Write to us or drop by our shop.
