What it is and who it is for

The Bitmain APW7 is a 1800W server power supply built for ASIC miners such as the Antminer S9, Z9mini, Z9, L3+, D9 and T9. It delivers a single 12V output from an ATX12V form factor and operates on either 100-120V or 200-240V mains at 50/60Hz. The unit is new and rated for ambient temperatures from 0°C to 35°C.

The spec that decides fit

Maximum output is 1000W at 110-120V input and 1800W at 220-240V input, so the available mains voltage directly determines whether the unit can power your miner. Conversion efficiency is 95%, compared with 93.5% on the older APW3++, meaning less waste heat and lower electricity cost. Automatic shutdown protects attached hardware if a circuit fault or excessive internal temperature occurs.

Installation and common pitfalls

The supply measures 206x110x62mm, weighs 4kg and uses a single fan for cooling; ensure the chassis can accommodate those dimensions and airflow. It is not suitable for builds that require multiple voltage rails, standard ATX motherboard connectors or operation above 35°C ambient. Buyers needing higher wattage at 110V or redundant hot-swap modules should look elsewhere.

Questions about this item

What does the 1800W rating mean when the unit is running on a 220-240V supply?

At 220-240V input the APW7 can deliver its full 1800W maximum output to power high-performance ASIC miners.

How does the ATX12V design and single 12V rail affect what I can connect?

The ATX12V form factor provides a single 12V rail rated for up to 1800W, so all connected hash boards draw from one high-current 12V source.

Will the 206x110x62mm case and single fan fit in my mining frame?

The compact 206 mm length, 110 mm width and 62 mm height with one integrated fan is designed to slide into standard Antminer chassis slots.
