Product Appearance

Power Supply
It also functions with a programming interface to control voltage. Although its two inductors and transformers cause higher costs, they provide a stable power supply. One of the 12V 1.5A cooling fans is at the back of the power supply for successful heat emission through proper ventilation. To prevent oxidation and moisture intrusion, it uses an air exhaustion method. The power supply case is suitable for heat dissipation.

It has three hash rate boards with aluminum heat sinks on both sides. The aluminum heat sink has a high density, and the two heat sinks have 26 spring screws. The temperature on the side of the miner of 45.3℃ and the cooling fan bearing is 66.5℃.
