Antminer K7 CKB Miner

The Bitmain Antminer K7 is an application-specific miner built for the Eaglesong algorithm used by the CKB network. It delivers a rated hashrate of 63.5Th/s for operators targeting Nervos Layer 1 rewards. The unit ships with its power supply included so deployment can begin once power and networking are ready.

Thermals noise and power draw

Two onboard fans move air through the chassis and produce a measured noise level of 75db during normal operation. The system draws 3080W from the wall while hashing at the rated speed. Heat is exhausted directly from the rear so rack spacing and aisle airflow must handle the continuous thermal load.

Build quality and daily implications

The complete miner weighs 18kg and uses a rigid sheet-metal frame designed for shelf or rack mounting in a controlled environment. An integrated power supply removes the need for an external PSU and reduces cable count to a single mains lead and one Ethernet link. Front-panel status LEDs and the web dashboard give immediate visibility of hash boards temperature and fan health.

Questions about this item

What power supply is required to run the Antminer K7?

The unit ships with a built-in power supply rated for 3080W, so no separate PSU purchase is needed.

How much noise does the miner generate in a typical room?

It produces 75db, which is comparable to a loud vacuum cleaner; plan for a dedicated or sound-dampened space.

What physical space and support does the 18kg chassis need?

Allow a sturdy shelf or rack that can hold 18kg and leave clearance around the two fans for airflow.
