The APW7 can work stably in environments with an ambient temperature of 50 °C. If the temperatures exceed 50°C, the power supply should be underclocked. Considering the high temperatures in mining operation, all internal components are selected with a standard of 105 °C, which has a much longer service life than a universal power supply at similar high temperatures.
Perfect function to protect miners, if the circuit is disturbed or the power supply has a higher indoor temperature, it is automatically switched off for protection, including undervoltage protection, over-current protection, over-current protection and short circuit protection.
Compare with APW3 ++ 93.5% conversion efficiency, APW7 power supply is 95% conversion efficiency, which means that APW7 more electricity costs, efficiency, very quiet, performance.
As with other mining equipment, the fan and power cable interface are located on the front of the power supply, allowing easy heat dissipation throughout the lead.
An APW7 can power a S9i, L3++, D3, V9, X3, E3 or Z9 mini. This APW7 has 5 pairs of 6-pin PCI-E connectors (d. 10 ports), supports back wiring, is easy for the user to install and provides effective wear resistance.
