According to reports, the Antminer APW7 power supply is a high-efficiency DC power supply designed and produced by Bitmain. The power supply adopts a single-phase AC input and a single-channel DC 12V output design, which can meet the use of common DC loads within 12V 1800W, and is especially suitable for occasions such as servers and mining machines that have strict power requirements. The power supply has the characteristics of small size, high power density, and output ripple of less than 1%. It also supports undervoltage, short circuit, overload, and overtemperature protection, and can automatically resume normal operation after the fault is removed.

In terms of performance, the Antminer APW7 power supply has a rated output power of 1800W. Compared with the previous generation product APW3++, the rated output power of the APW7 power supply has been increased by 200W, which can drive a higher-power mining machine while increasing the power margin. Thanks to the increase in power margin, the APW7 power supply can effectively deal with the problem of sudden increase in mining machine power and ensure the stability of mining machine operation.
In addition to increasing power, another improvement of the APW7 power supply is the improvement of the maximum conversion efficiency. Compared with APW3++, the maximum conversion efficiency of the APW7 power supply has increased by 1.5%, which will save more power. Taking the Antminer S9i-13T with the APW7 power supply as an example, the power of the mining machine is 1300W. A single mining machine using the APW7 power supply will save about 0.462 kWh of electricity per day compared to the APW3++ power supply. If calculated at an electricity price of 0.5 yuan/kWh, assuming that a miner has 1,000 mining machines, it can save about 84,315 yuan in electricity bills a year. For large mining farms with many mining machines, the APW7 power supply is undoubtedly a power-saving tool.
In addition, the Antminer APW7 power supply has an optimized heat dissipation design to ensure stability under high-temperature operation. It can work at full load in an environment below 60°C. Miners can stay away from the troubles caused by the power supply not being able to work normally due to high temperatures in summer.
At present, the Antminer APW7 power supply has officially landed on the Bitmain official website, priced at 650 yuan, and is available for sale. It can be shipped as soon as 7 days after the user pays. If you want to replace or purchase a mining machine power supply in the near future, you may wish to pay attention to this new product.
